Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Application No. 60/908,755, filed on Mar. 29, 2007. The disclosure
of the above application is incorporated herein by reference.
FIELD
[0002] The present disclosure relates to a mechanism for mounting
and dismounting a bearing to a shaft. More particularly, the
present disclosure relates to a concentric locking mechanism
operable to secure and remove the bearing from one side
thereof.
BACKGROUND AND SUMMARY
[0003] One known bearing mounting mechanism includes a sleeve, nut,
and washer locking mechanism. This design uses a sleeve with a
straight bore and tapered outer surface which fits onto the shaft.
One end of the sleeve outer surface has a threaded portion and
there is a slit through the entire axial length of the sleeve. The
bearing inner ring bore has a taper which matches the sleeve outer
surface. The bearing is driven up the tapered sleeve with a nut
that threads onto the tapered sleeve. This compresses the sleeve
and locks the bearing to the shaft. A lockplate is then used to
keep the nut from rotating and loosening from the sleeve. The
bearing is dismounted by removing the lockplate, loosening the nut
and driving the bearing back down the taper.
[0004] Another mechanism uses a tapered sleeve and tapered inner
ring bore as described above but has a nut that is held captive to
the inner ring. This design is installed by turning the nut and
driving the bearing up the tapered sleeve. Once the bearing is
tight, a lockplate is used to secure the nut and prevent rotation.
To remove this bearing, the lockplate is removed and the nut is
rotated in the opposite direction. The nut is held to the inner
ring so this rotation drives the bearing down the sleeve and it
becomes loose to the shaft.
[0005] Another mechanism requires the use of two tapered sleeves
and an inner ring with two matching tapers. The tapers on the inner
ring begin with a thin cross section at each end of the bearing,
both increasing in thickness until they meet in the center of the
bore. The first tapered sleeve extends through the entire bearing
inner ring and contains a threaded portion on each end. The second
tapered sleeve extends only to the center of the bore and slips
over the extended length of the first tapered sleeve. The second
tapered sleeve is held captive in the first threaded nut. For
installation, the second tapered sleeve is installed over the first
tapered sleeve and the first threaded nut engages the first
threaded portion of the first tapered sleeve. This action pulls the
first tapered sleeve into engagement with the first inner ring
taper and pushes the second tapered sleeve into engagement with the
second inner ring taper which compresses both sleeves causing the
bearing to become tight to the shaft. At this point a screw on the
first threaded nut is tightened to prevent rotation and loosening.
For removal, the screw on the first threaded nut is loosened. The
first threaded nut is loosened from the first tapered sleeve and
the second tapered sleeve is removed from the bearing. The second
captive nut is then threaded onto the second threaded portion of
the first tapered sleeve which removes the first tapered sleeve
from the bearing causing the bearing to become loose to the
shaft.
[0006] Another mechanism uses a sleeve with a straight bore and a
multiple tapered outer surface. The inner ring has a multiple
tapered surface to match the sleeve. The sleeve extends from both
ends of the inner ring. Each side of the bearing has a washer which
rests against the end face of the inner ring. The sleeve outer
diameter on both ends has a recessed slot. A flange sits inside
that slot on both sides. Each flange has threaded holes containing
setscrews. To install the bearing the mounting side flange is used,
the setscrews are tightened which move the sleeve axially and drive
the bearing up the tapered surface tightening it to the shaft. To
remove the bearing, the mounting side flange is loosened and the
dismounting side flange is engaged. As these setscrews are turned
toward the bearing, the sleeve moves in the opposite axial
direction loosening it from the shaft.
[0007] The first limitation of the prior art is obtaining the
proper axial movement to tighten the bearing to the shaft while not
over tightening the bearing. If the bearing is over tightened then
the necessary clearance in the bearing will be reduced or removed
causing decreased life. The sleeve, nut, washer and captive nut
designs encounter this problem. They use the "turn of the nut"
tightening method, which provides a specific amount of rotation to
apply to the nut in order to obtain the proper shaft lock. This
method skews the accuracy of the shaft lock because it relies on
the consumer's personal judgment of a "zero point", which differs
between each user. The "zero point" is often defined by the
manufacturer as when the nut is "hand tight". Other manufacturers
require the user to tighten until the nut is "tight", giving no
quantitative value to tighten to. Both methods yield variation
between installers which will cause variation in the bearing
internal clearance and ability to lock the bearing to the
shaft.
[0008] The other major limitation with prior solutions is the
method of dismounting the bearing from the shaft. The sleeve, nut,
washer assembly provides no means of removing the bearing from the
shaft. To remove the bearing, the nut is loosened from the tapered
sleeve and then the bearing must be driven down the sleeve. This is
accomplished by hitting either the shaft or bearing with a hammer
to release the sleeve from the bearing. This often does not work
and the bearing must be cut off the shaft which may damage
expensive shafting and can add additional machine downtime. The
multiple tapered sleeve and multiple sleeve designs utilize a
separate mechanism for mounting and dismounting the bearing. The
dismounting mechanism is on the opposite side of the mounting
mechanism. This is undesirable in many applications due to a lack
of space or access to the back side of the bearing. In these
applications the dismounting feature of this bearing is not
usable.
[0009] It may be beneficial to incorporate a means of tightening a
bearing to a shaft using a sleeve that concentrically constricts
around the shaft. It may be desirable to incorporate certain design
considerations such as easy installation, easy removal, minimal
pieces, high strength, small size, and cost effectiveness. A need
may exist for a locking mechanism that would feature some or all of
these design considerations.
[0010] The disclosure provides a means to secure the bearing to a
shaft. The design provides a concentric locking mechanism to
minimize the amount of raceway distortion caused by the locking
mechanism. This design also provides a means to secure and remove
the bearing on one side of the bearing using the same set of
components. The disclosure also uses a metered torque tightening
approach to ensure the proper installation.
[0011] The present disclosure provides a mechanism for mounting and
dismounting a bearing to a shaft. The mechanism includes a split
sleeve and a receptive flange adapted to be axially fixed to the
bearing. A positioning flange is coupled to the split sleeve to
form a tapered bushing assembly. At least one screw extends through
at least a portion of the positioning flange and the receptive
flange. The screw threadingly engages one of the positioning flange
and the receptive flange. Rotation of the screw in a first
direction axially drives the sleeve into engagement with the
bearing to collapse the split sleeve into engagement with the
shaft. Rotation of the screw in a second opposite direction axially
pulls the sleeve out of engagement with the bearing to return the
sleeve to a more undeformed state. The sleeve is released from
engagement with the shaft.
[0012] Additionally, the present disclosure provides a mechanism
for locking a bearing to a shaft including a split sleeve having a
radially extending flange formed at one end. The flange includes
first and second bores. The second bores include internal threads.
The split sleeve has a tapered surface adapted to engage the
bearing. A first screw extends through the first bore and is
adapted to threadingly engage the bearing. Rotation of the first
screw axially drives the tapered surface into engagement with the
bearing to collapse the split sleeve into engagement with the
shaft. A second screw is threadingly engaged with the internal
thread of the second bore and is adapted to engage the bearing.
Rotation of the second screw axially drives the tapered surface out
of engagement with the bearing to allow the split sleeve to be
moved relative to the shaft.
[0013] A method of locking a bearing to a shaft includes coupling a
positioning flange to a split sleeve. A receptive flange is coupled
to the bearing. A screw is threadingly engaged with a threaded bore
formed in one of the positioning flange and the receptive flange.
The screw is rotated in a first direction to axially translate the
split sleeve into engagement with the bearing to collapse the split
sleeve into engagement with the shaft.

DESCRIPTION
[0020] FIG. 1 of the present disclosure provides a locking
mechanism 10 operable to mount and dismount an exemplary bearing
assembly 12 to a shaft (not shown). Locking mechanism 10 includes a
split sleeve 14 with a straight bore 16, an axially extending gap
17 and a tapered outer surface 18. A portion 19 of the outer
surface of split sleeve 14 is substantially cylindrically shaped. A
length of split sleeve 14 is defined so that it will extend axially
from one end of a bearing inner ring 20 of bearing assembly 12.
Bearing inner ring 20 has a bore with a tapered surface 22 matching
the tapered outer surface 18 of split sleeve 14. Inner ring 20
includes an extension portion 23 on one side which matches the
extension end of split sleeve 14.
[0021] A positioning flange 24 includes a threaded bore 26. The
extended portion of split sleeve 14 includes an external thread 28
terminating at a shoulder 30. Positioning flange 24 is threadingly
engaged with split sleeve 14 and fixed against shoulder 30.
Positioning flange 24 also includes a plurality of pockets 32
circumferentially spaced apart from one another. Each pocket is
defined by a stepped slot 34 radially inwardly extending from an
outer cylindrical surface 36 of positioning flange 24. An aperture
38 inwardly extends from an end face 40 in communication with
stepped slot 34.
[0022] A receptive flange 42 includes a bore 44 that receives the
extension portion 23 of the inner ring 20. An outer ring groove 46
is formed on extension portion 23 and an inner ring groove 48 is
formed within bore 44. A snap ring 50 axially fixes receptive
flange 42 to bearing inner ring 20.
[0023] Receptive flange 42 also includes a recess 52 sized to
accept positioning flange 24. As such, positioning flange 24 is
substantially concentrically aligned with receptive flange 42. A
plurality of threaded blind bores 54 axially extend from a bottom
surface 56 of recess 52. Blind bores 54 are circumferentially
spaced apart along a matching pattern to pockets 32.
[0024] A screw member 60 includes an enlarged head 62 positioned
within each pocket 32. A threaded shank portion 64 of screw member
60 extends through aperture 38 and threadingly engages threaded
blind bore 54. Each screw member 60 acts between the positioning
flange 24 and receptive flange 42 in order to affect axial movement
between the inner ring 20 and split sleeve 14 in both directions.
The screw members 60 are used to create axial movement of split
sleeve 14 relative to the bearing inner ring 20. The movement of
positioning flange 24 and split sleeve 14 is axial in direction,
substantially without rotation. Each aperture 38 is sized and
positioned to allow access for a tool to drivingly engage screw
member 60. The screw members 60 are rotated in a first direction
and tightened with a torque wrench to a specified torque value
yielding a consistent, repeatable value. The forced engagement
between tapered outer surface 18 and tapered surface 22 collapses
split sleeve 14 and locks the bearing assembly 12 to the shaft.
Split sleeve 14 may be constructed from a resilient material such
as SAE 4140. Accordingly, the size of straight bore 16 is greater
when split sleeve 14 is in a free state than when in an engaged
state while being driven into contact with bearing inner ring 20.
Other materials may also be used without departing from the scope
of the present disclosure.
[0025] To dismount the bearing assembly 12, screws 60 are rotated
in an opposite direction to cause enlarged heads 62 to engage a
wall 66 defining a portion of pocket 32. This, in turn, causes
axial movement of split sleeve 14 in the opposite direction.
Disengagement of tapered outer surface 18 from tapered surface 22
allows split sleeve 14 to elastically return to a more undeformed
state thereby releasing the circumferential grasp on the shaft. A
loosening of the bearing assembly 12 from the shaft results.
[0026] The invention improves the customer simplicity of the
installation and removal, by providing the means for installation
and removal on the same side of the bearing. The invention
incorporates a feature that allows the customer to mount and
dismount the bearing using screws all contained on one side of the
bearing. This arrangement provides a more efficient means of
installation and removal. The invention also provides a qualitative
method of tightening the bearing to the shafts by providing a
torque value to be applied with a torque wrench. This yields a more
precisely tightened bearing which ensures the proper holding force
and proper bearing internal clearance.
[0027] An alternate locking mechanism 100 is substantially similar
to locking mechanism 10. As such, similar elements will be
identified with reference numerals including a prime suffix.
Locking mechanism 100 includes a plurality of cap screws 102
extending through bores 104 formed in positioning flange 24'. Cap
screws 102 are rotated in a first direction to collapse split
sleeve 14' about the shaft. A predetermined torque is applied to
each cap screw 102 to provide the axial translation of split sleeve
14' in relation to bearing inner ring 20' and provide the desired
circumferential squeezing or clamping of split sleeve 14' about the
shaft.
[0028] To dismount bearing assembly 12' from the shaft, cap screws
102 are rotated in the opposite direction to disengage them from
threaded bores 54' formed in receptive flange 42'. Set screws 106
are then rotated in a first direction to place an end face 108 of
each set screw 106 in engagement with a face 110 of receptive
flange 42'. Set screws 106 include external threads in threading
engagement with internal threads formed in positioning flange 24'
such that rotation of set screws 106 causes axial translation of
set screw 106 relative to positioning flange 24'. Continued
rotation of each set screw 106 imparts a force on face 110 to cause
split sleeve 14' to be removed from engagement with bearing inner
ring 20'. As the tapered outer surface 18' of split sleeve 14'
disengages from the tapered surface 22' of bearing inner ring 20',
split sleeve 14' resiliently returns to a less deformed condition
and disengages the shaft.
[0029] An alternate locking mechanism 200 is substantially similar
to locking mechanism 10. As such, similar elements will be
identified with reference numerals including a double prime suffix.
Locking mechanism 200 contains a flanged split sleeve 202 with a
straight bore 16'', an axially extending gap 17'', a tapered outer
surface portion 18'', a cylindrical outer surface portion 19'', a
plurality of holes 204 circumferentially spaced apart from one
another, and a plurality of threaded holes 206 circumferentially
spaced apart from one another. An inner ring 20'' includes a
plurality of threaded blind bores 54'' axially extending from an
end face 208. Blind bores 54'' are circumferentially spaced apart
along a matching pattern to holes 204. Locking mechanism 200
includes a plurality of cap screws 210 extending through holes 204
in flanged split sleeve 202. Cap screws 210 are rotated in a first
direction to collapse flanged split sleeve 202 about the shaft. A
predetermined torque is applied to each cap screw 210 to provide
axial translation of flanged split sleeve 202 in relation to
bearing inner ring 20'' and provide the desired circumferential
interference or clamping of flanged split sleeve 202 about the
shaft.
[0030] To dismount bearing assembly 12'' from the shaft, cap screws
210 are rotated in the opposite direction to disengage from the
threaded bores 54'' formed in inner ring 20''. Cap screws 210 are
then inserted into threaded holes 206 in flanged split sleeve 202.
Cap screws 210 are then rotated in the first direction to axially
translate the cap screws 210 relative to flange split sleeve 202
and engage an end 212 of each cap screw 210 with end face 208 of
inner ring 20''. Continued rotation of each cap screw 210 imparts a
force on end face 208 to cause flanged split sleeve 202 to be
removed from engagement with bearing inner ring 20''. As the
tapered outer surface 18'' of flanged split sleeve 202 disengages
from the tapered surface 22'' of bearing inner ring 20'', flanged
split sleeve 202 resiliently returns to a less deformed condition
and disengages the shaft.
[0031] Another alternate locking mechanism 300 is depicted in FIG.
4. Locking mechanism 300 is substantially similar to locking
mechanism 10. As such, similar elements will be identified with
like reference numerals including a triple prime suffix. Locking
mechanism 300 includes a plurality of screw members 302 each having
an enlarged head 304 positioned within a pocket 306 formed within a
receptive flange 308. Each screw member 302 is free to rotate but
restricted from axial movement relative to receptive flange 308. A
positioning flange 310 includes threaded apertures 312 in receipt
of screw members 302. Each screw member 302 further includes a
drive socket 314 formed on an end opposite enlarged head 304. The
remaining components of locking mechanism 300 are substantially
similar to those previously described in relation to locking
mechanism 10. The function of locking mechanism 300 is also
substantially similar to locking mechanism 10 in that rotation of
screw members 302 causes relative axial movement between split
sleeve 14''' and bearing inner ring 20''' causing split sleeve
14''' to lockingly engage and disengage a shaft as previously
described.
[0032] FIG. 5 depicts another locking mechanism identified at
reference numeral 400. Locking mechanism 400 is substantially
similar to locking mechanism 100 shown in FIG. 2. Locking mechanism
400 differs from locking mechanism 100 in that a split sleeve 402
includes a tapered outer surface 404 having a taper in the opposite
direction as that of tapered outer surface 18'. A bearing 405
includes a bearing inner ring 406 having a tapered surface 408
tapered in a direction matching tapered outer surface 404.
Accordingly, the direction of taper formed on tapered surface 408
is in the opposite direction as tapered surface 22'. By changing
the direction of the tapers, a reduction in split sleeve diameter
is achieved by pulling split sleeve 402 through bearing inner ring
406. Split sleeve 402 may be driven into contact and clamped about
a shaft by positioning cap screws 410 within threaded bores 412
formed in a positioning flange 414. An end face 416 of each cap
screw 410 is driven into engagement with a face 418 of a receptive
flange 420. Split sleeve 402 is drawn through bearing inner ring
406 to drive tapered outer surface 404 into contact with tapered
surface 408 and collapse split sleeve 402, creating a lock to the
bearing.
[0033] For bearing removal, cap screws 410 are removed from
threaded bores 412 and placed within throughbores 422 formed in
positioning flange 414. Cap screws 410 are engaged with threaded
bores 424 formed in receptive flange 420. Rotation of cap screws
410 causes positioning flange 414 to move toward receptive flange
420. Previously contacting tapered surfaces 404, 408 disengage from
one another and split sleeve 402 disengages the shaft.
[0034] Furthermore, the foregoing discussion discloses and
describes merely exemplary embodiments of the present disclosure.
One skilled in the art will readily recognize from such discussion,
and from the accompanying drawings and claims, that various
changes, modifications and variations may be made therein without
departing from the spirit and scope of the disclosure as defined in
the following claims.
