DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0026] Please refer to FIGS. 1 and 2, which show an embodiment of
the instant disclosure. The embodiment provides a linear guideway
100 including a guide rail 1, a sliding block 2, two circulation
modules 3, two retainers 4, and two end cap modules 5. The
circulation modules 3 are coupled through the sliding block 2, the
retainers 4 are respectively disposed on the circulation modules 3,
and the end cap modules 5 are respectively fixed on two opposite
end surfaces 23 of the sliding block 2 (i.e., the front surface and
the rear surface of the sliding block 2 as shown in FIG. 2).
Moreover, the sliding block 2, the circulation modules 3, the
retainers 4, and the end cap modules 5 are slidably disposed on the
guide rail 1 and symmetrical to the guide rail 1.
[0027] Please refer to FIG. 3. The guide rail 1 is an elongated
structure, the axis of elongation of guide rail 1 defines a sliding
direction S, and the cross-section of the guide rail 1, which is
perpendicular to the sliding direction S, is approximately
I-shaped. Specifically, the guide rail 1 includes two elongated
rolled grooves 11 respectively formed on two opposite side surfaces
thereof (i.e., the left side surface and the right side surface of
the guide rail 1 as shown in FIG. 2), and each rolled groove 11 is
parallel to the sliding direction S. The other portion of each side
surface of the guide rail 1, which is connected to the edge of the
rolled groove 11, is defined as a contact surface 12. Each rolled
groove 11 has a bottom wall 111 and two loaded side wall 112
respectively connected to two opposite edges of the bottom wall 111
(i.e., the top edge and the bottom edge of the bottom wall 111 as
shown in FIG. 2).
[0028] Please refer to FIGS. 3 and 4. The sliding block 2 is an
elongated structure, and the length of the sliding block 2 is
smaller than the length of the guide rail 1. A mating trough 21 is
concavely formed on the sliding block 2, that is to say, the
cross-section of the sliding block 2, which is perpendicular to the
elongation direction of the sliding block 2, is approximately
U-shaped. The mating trough 21 of the sliding block 2 is slidably
sleeved at the guide rail 1. The elongation direction of the
sliding block 2 is parallel to the elongation direction of the
guide rail 1 (such as the sliding direction S). Two opposite inner
side surfaces of the mating trough 21 are respectively spaced apart
from the opposite side surfaces of the guide rail 1 (as shown in
FIG. 1A) for enabling the circulation module 3 and the retainers 4
to arrange between the opposite inner side surfaces of the mating
trough 21 and the opposite side surfaces of the guide rail 1.
[0029] The sliding block 2 includes two opposite side portions
substantially symmetrical to the guide rail 1, such that the
following description just discloses one side portion of the
sliding block 2. Specifically, the inner side surface of each side
portion of the mating trough 21 is formed with a positioning groove
211, two side positioning grooves 212, and two carrying walls
213.
[0030] One carrying wall 213 is arranged between the positioning
groove 211 and one side positioning groove 212, and another
carrying wall 213 is arranged between the positioning groove 211
and another side positioning groove 212. In the cross-section of
the sliding block 2 perpendicular to the sliding direction S (as
shown in FIG. 1A), the perpendicular bisectors of the carrying
walls 213 are perpendicularly intersected at a position, which is
at one side of the positioning groove 211 away from the guide rail
1. In other words, the positioning groove 211 and the carrying
walls 213 are corresponding to the rolled groove 11. Specifically,
the positioning groove 211 faces the bottom wall 111 of the rolled
groove 1 and the carrying walls 213 respectively face the loaded
side walls 112 of the rolled groove 11.
[0031] Moreover, a portion of the sliding block 2 apart from each
carrying wall 213 in a predetermined distance is formed with a
penetrating accommodating channel 22 along the sliding direction S.
The carry walls 213 together with the faced loaded side walls 112
are respectively corresponding to the accommodating channels 22.
Specifically, in the cross-section of the sliding block 2
perpendicular to the sliding direction S, the perpendicular
bisector of each carrying wall 213 passes through the center of the
corresponding accommodating channel 22.
[0032] As shown in FIG. 3, the circulation modules 3 are
respectively installed on two opposite inner side surfaces of the
sliding block 2 (i.e., the inner left side surface and the inner
right side surface of the sliding block 2 as shown in FIG. 3). The
following description just discloses one circulation module 3 and
the corresponding components, because the circulation modules 3
have the same structure.
[0033] Please refer to FIGS. 5 and 6. The circulation module 3
includes two circulation tubes 31, two separating sheets 32, and
two rolling units 33. Each circulation tube 31 in the instant
embodiment is formed by assembling several half tubes, but the
following description takes each circulation tube 31 to be one
piece for conveniently explaining the construction. Each rolling
unit 33 in the instant embodiment takes the rolling pillars
connected by the chain for example, but the rolling unit 33 is not
limited thereto.
[0034] As shown in FIG. 7, each circulation tube 31 includes a
straight portion 311 and two U-like cornering portions 312
respectively extended from two opposite ends of the straight
portion 311. The length of the straight portion 311 of each
circulation tube 31 is greater than the length of accommodating
channel 22. The ends of two cornering portions 312 of each
circulation tube 31 are facing to each other, and the distance of
the ends of two cornering portions 312 of each circulation tube 31
is smaller than the length of accommodating channel 22. One of the
cornering portions 312 of each circulation tube 31 includes a
fill-in opening 313 formed on a portion thereof adjacent to the
straight portion 311. The separating sheet 32 is arced and
installed on the circulation tube 31 to shield the fill-in opening
313, such that the circulation tube 31 and the corresponding
separating sheet 32 are jointly defines a rolling path, in which
the rolling path communicates with the outer space via the ends of
cornering portions 312 of the corresponding circulation tube
31.
[0035] As shown in FIG. 8, the straight portion 311 of each
circulation tube 31 is configured to couple through the
corresponding accommodating channel 22, and the straight portion
311 is firmly arranged in the corresponding accommodating channel
22 by a step-like structure formed on the outer surface of the
straight portion 311. The ends of the cornering portions 312 of
each circulation tube 31 are disposed on the corresponding carrying
wall 213. A portion of the straight portion 311 of each circulation
tube 31 adjacent to the fill-in opening 313 is protruding out of
the sliding block 3, and the cornering portion 312 having the
fill-in opening 313 is arranged outside the adjacent cornering
portion 312 without the fill-in opening 313.
[0036] In other words, when viewing the cornering portions 312 of
the circulation module 3 from one end portion of the sliding block
2, the cornering portion 312 having the fill-in opening 313 of each
circulating tube 31 (i.e., the position of separating sheet 32) is
arranged outside the cornering portion 312 without the fill-in
opening 313 of another circulating tube 31. The circulation tubes
31 of each circulation module 3 are installed on the sliding block
2 in a staggered and crossed arrangement.
[0037] The rolling unit 33 is rollably arranged in the
corresponding circulation tube 31 via the fill-in opening 313, in
which the rolling unit 33 is rolling out of the circulation tube 31
from the end of one cornering portion 312 along the carrying wall
213, and then rolling into the circulation tube 31 via the end of
another cornering portion 312 for establishing an entire
circulation loop. The separating sheet 32 is installed on the
circulation tube 31 after the installation of the rolling unit 33,
so that the rolling unit 33 is shield by the circulation tube 31
and the separating sheet 32, thereby preventing the rolling unit 33
from exposing out of the sliding block 2. Specifically, the rolling
unit 33 is rollable on a track structure, which is formed on the
inner surfaces of the circulation tube 31 and the separating sheet
32, and the corresponding carrying wall 213.
[0038] Additionally, a portion of each circulation tube 31
protruding out of the sliding block 2 has an oil-guiding opening
314. Each oil-guiding opening 314 is communicated with the inner
space of the corresponding circulation tube 31, and the oil-guiding
openings 314 of each circulation module 3 are arranged adjacent to
each other, such that each oil-guiding opening 314 is configured to
provide a lubricating oil to be injected into the circulation tube
31.
[0039] As shown in FIGS. 1 and 2, the retainers 4 are respectively
clipped between the opposite inner side surfaces of the mating
trough 21 and the opposite side surfaces of the guide rail 1. The
retainers 4 are configured to position and keep the positions of
the circulation modules 3 with respect to the guide rail 1. The
following description discloses one retainer 4 and the
corresponding components, because the retainers 4 have the same
structure and symmetrical to the guide rail 1.
[0040] Please refer to FIGS. 5 and 6. The retainer 4 is elongated,
and the length of the retainer 4 is greater than the length of the
sliding block 2. The retainer 4 includes a retaining member 41, a
supporting member 42, and two dustproof strips 43. The retaining
member 41 is integrally formed, and the cross-section of the
retaining member 41, which is perpendicular to the elongated
direction of the retaining member 41, is approximately
V-shaped.
[0041] Specifically, the retainer 4 has an elongated base portion
411 and two side wing portions 412 respectively and slantingly
extended from two opposite long edges of the base portion 411 along
two different directions (i.e., the upper left direction and the
lower left direction of the base portion 411 as shown in FIG. 5).
The base portion 411 has a receiving groove 4111 formed on the
center portion thereof along the elongation direction thereof. The
base portion 411 further has two pair of clipping bumps 4112
respectively formed adjacent to two opposite ends of the receiving
groove 4111 (i.e., the left end and the right end of the receiving
groove 4111 as shown in FIG. 5).
[0042] Moreover, each side wing portion 412 has an elongated
positioning opening 4121 formed along the elongation direction
thereof. One positioning opening 4121 is offset with respect to the
receiving groove 4111 along a first direction (i.e., the upper
positioning opening 4121 is formed toward the right side of the
receiving groove 4111 as shown in FIG. 5), and another positioning
opening 4121 is offset with respect to the receiving groove 4111
along a second direction opposite to the first direction e., the
lower positioning opening 4121 is formed toward the left side of
the receiving groove 4111 as shown in FIG. 5),
[0043] Specifically, each positioning opening 4121 is surroundingly
defined by two elongated walls 4123 and two arced walls 4122 of the
side wing portion 412. Two positioning flanges 4124 are
respectively extended from the two elongated walls 4123 of each
side wing portion 412. The positioning flanges 4124 of each side
wing portion 412 are arranged in the corresponding positioning
opening 4121 and facing to each other. The distance between the
positioning flanges 4124 of each side wing portion 412 is smaller
than the biggest distance of arced walls 4122. Moreover, a mating
flange 4125 is formed on a portion of each side wing portion 412
away from the base portion 411, and the mating flange 4125 conforms
to the side positioning groove 212.
[0044] The supporting member 42 has a mating post 421 and two
clipped pillars 422. The cross-section of the mating post 421,
which is perpendicular to the elongation direction of the mating
post 421, is hexagon, and two opposite portions of the mating post
421 (i.e., the front portion and the rear potion of the mating post
421 as shown in FIG. 5) respectively conform to the positioning
groove 211 and the receiving groove 4111. The clipped pillars 422
are respectively and integrally extended from two end surfaces of
the mating post 421 (the left end surface and the right end surface
of the mating post 421 as shown in FIG. 5).
[0045] Moreover, one side portion of the mating post 421 is wedged
to the receiving groove 4111 of the retaining member 41, and the
clipped pillars 422 are respectively clipped by the pairs of
clipping bumps 4112. The dustproof strips 43 are respectively
disposed (e.g., adhered) on the side wing portions 412 away from
the base portion 411 and approximately located at the back of the
mating flange 4125. That is to say, the dustproof strips 43 are
respectively disposed (e.g., adhered) on two outside end portions
of the retaining member 41.
[0046] Please refer to FIGS. 1A and 9, and with reference
occasionally made to FIGS. 5 and 6. The relationship between the
retainer 4 and the corresponding components is disclosed as

the mating post 421 is wedged to the positioning groove 211, and
the mating flanges 4125 of the side wing portions 412 are
respectively wedged to the side positioning grooves 212. The
cooperation of the retainer 4 and the circulation module 3: the
circulation tubes 31 are respectively coupled through the
positioning openings 4121 of the retaining member 41, in more
detail, the ends of cornering portions 312 of each circulation tube
31 are respectively wedged to the arced walls 4122 and the adjacent
end surfaces of the positioning flanges 4121, and part of the
rolling unit 33 disposed on each carrying wall 213 is arranged in
the corresponding positioning opening 4121. The cooperation of the

dustproof sheet 522 integrally extended from the rear portion of
the oil-guiding block 521. The oil-guiding block 521 has an
oil-guiding passage 5211 by concavely formed on the front portion
thereof. The dustproof sheet 522 has a dustproof brush 5221, and
the dustproof brush 5221 is conforming to the guide rail 1 for
abutting against the guide rail 1. Specifically, the oil-guiding
passage 5211 defines three inlets 5212 and two outlets 5213. The
oil-guiding passage 5211 is concavely formed on a surface of the
oil-guiding block 521 away from the dustproof sheet 522. The
oil-guiding block 521 has a protrusion 523 substantially around the
oil-guiding passage 5211.
[0052] Please refer to FIG. 12, and with reference occasionally
made to FIGS. 10 and 11. The dustproof member 52 is installed
(wedged) in the accommodating slot 517 of the cap 51. The surface
of the oil-guiding block 521 away from the dustproof sheet 522 is
coplanar with the inner surface 513 of the cap 51, and the
protrusion 513 is protruding out of the inner surface 513. The
inlets 5212 of the oil-guiding passage 5211 are respectively
communicated with the oil-input hole 515 and the side oil-input
holes 516. Additionally, an oil nozzle (not numbered) can be
installed at the oil-input hole 515, and two socket set screws (not
numbered) can be respectively installed at the side oil-input holes
516.
[0053] Moreover, the dustproof brush 5221 is arranged on the rail
opening 511. The dustproof sheet 522 and the cap 51 jointly defines
an accommodating space 53, that is to say, when the dustproof
member 52 received in the accommodating slot 517, the remnant space
of the accommodating slot 517 is regarded as the accommodating
space 53.
[0054] Please refer to FIGS. 1B, 2, and 12. The end cap module 5 is
fixed on the end surface 23 of the sliding block 2, a portion of
each circulation tube 31 exposed from the sliding block 2 (i.e.,
the cornering portions 312) and the separating sheet 32 are
arranged in the accommodating space 53, and the separating sheet 32
and the cornering portion 312 having the fill-in opening 313 are
approximately contact the dustproof sheet 522. Moreover, the end of
each retaining member 41 protruding out of the sliding block 2 is
abutted against the dustproof sheet 522. The protrusion 523 of the
oil-guiding block 521 is seamlessly abutted against the end surface
23 of the sliding block 2, and the outlets 5213 of the oil-guiding
passage 521 respectively align the corresponding oil-guiding
openings 314 of the circulation modules 3. In other words, the
oil-guiding passage 5211 is arranged between the oil-input hole 515
and the side oil-input holes 516 of the cap 51 and the adjacent
oil-guiding openings 314 to enable the oil-input hole 515 and the
side oil-input holes 516 of the cap 51 to communicate with the
adjacent oil-guiding openings 314 via the oil-guiding passage
5211.
