  • ball retainer structure 42 in one example, comprises four ball retainer segments 54 , each operatively associated with adjacent ball retainer segments along longitudinal sides thereof to form a polygonally shaped ball retainer structure having a bore there through for receiving a shaft 70 .
  • Each ball retainer segment 54 includes an outer radial surface 56 and an inner radial surface 58 .
  • Axial ball tracks 60 are formed in the outer radial surface 56 of each ball retainer segment 54 and include load bearing portions 62 , return portions 64 and turnarounds 66 .
  • the load bearing and return portions of the ball tracks in this embodiment are undercut to facilitate loading and retention of the bearing balls 46 therein. This also eliminates the need for a separate retainer structure to keep the bearing balls in the ball tracks.
  • a longitudinal bore 68 in the inner radial surface 58 of the ball retainer segment 54 extends substantially the length of the load bearing portions 62 and accesses support shaft 70 .
  • support shaft 70 is illustrated as a substantially cylindrical shaft, support members of other configurations may also be used.
  • a plurality of bearing balls 46 are disposed in the ball tracks 60 with those bearing balls 46 in the load bearing tracks 62 extending at least partially into longitudinal bores 68 to contact support shaft 70 .
  • a pair of axial ball tracks 60 are formed in each outer radial surface 56 of the ball retainer segment with the corresponding load bearing tracks being oriented in substantially parallel adjacent relation. This orientation facilitates enhanced load capacity and maximizes space utilization for a more compact and efficient bearing ball arrangement.
  • a locking structure in the form of locking clips 72 are formed on opposing longitudinal ends of each ball retainer segment 54 to facilitate assembly with outer housing sleeves 48 , 50 , discussed in greater detail herein below.
  • the linear motion bearing assembly in accordance with one preferred embodiment includes a pair of outer housing sleeves 48 , 50 which, when assembled serve to close and protect the exposed outer radial surfaces 56 of ball retainer structure 42 .
  • the outer radial surface 74 of sleeves 48 , 50 are preferably of a smooth cylindrical shape and are configured and dimensioned to fit within a mounting bore of a tool carriage (not shown).
  • the inner radial surface 76 of sleeves 48 , 50 include mounting surfaces 78 which are configured to receive at least a portion of load bearing plates 44 therein.

  • Mounting surfaces 78 may be recessed from outer radial surface 74 by a distance approximating the cross-sectional radial thickness of bearing plate to housing intermediary load structure 52 . In this manner, the outer housing sleeves 48 , 50 and the bearing plate to housing intermediary load structure 52 combine to form a relatively smooth and uniform outer radial surface of the linear motion bearing assembly 40 . See, FIG. 6 .
  • mounting surfaces 78 are configured to fit the shape of individual ball retainer segments 54 .
  • a plurality of locking bores 82 are formed in respective ends of sleeves 48 , 50 in alignment with locking clips 72 of ball retainer segments 54 .

  • load bearing plate 44 is elongated along the longitudinal axis of the bearing assembly and includes an outer radial surface 84 , an inner radial surface 86 , and a pair of side wall surfaces 88 .
  • the outer radial surface 84 is substantially accurate and may include a crown portion 90 disposed on the outer radial surface 84 in a medial position. Crown portion 90 is configured and dimensioned to permit the load bearing plates 44 to rock both circumferentially and longitudinally into and out of parallelism with the axes of the ball retainer structure 42 .
  • the inner radial surface 86 of the load bearing plate is advantageously provided with a pair of axial grooves which serve as the upper surface of load bearing portions 62 of ball tracks 60 .
  • a longitudinal groove 92 is formed in each side wall surface 88 of load bearing plates 44 . These grooves 92 make up a side wall of the axial ball tracks 60 and guide bearing balls 46 as they move through the return portion thereof.
  • bearing plate to housing intermediary load structure 52 is illustrated in a C-ring configuration having an outer radial surface 94 conforming substantially in dimension to the outer radial surface 74 of sleeves 48 , 50 .
  • the inner radial surface 96 is substantially parallel to the outer radial surface and is configured and dimensioned, when assembled, to contact crown portion 90 of load bearing plates 44 .
  • the radius of curvature of the crown portion 90 in the transverse direction may be smaller than the radius of curvature of the inner radial surface of the bearing plate to housing intermediary load structure 52 .
  • This configuration allows the plates to rock circumferentially and longitudinally with respect to the inner surface of the bearing plate to housing intermediary load structure 52 .
  • crown portion 90 is substantially flat as shown in FIG. 4 .
  • the bearing plate to housing intermediary load structure 52 encompasses and engages extension portions 80 of sleeve 48 , 50 to assist in enclosing and protecting ball retainer structure 42 .
  • the bearing plate to housing intermediary load structure 52 may extend substantially the entire longitudinal length of the bearing assembly.
  • the bearing plate to housing intermediary load structure is preferably formed of a hard abrasion resistant material such as, for example, stainless steel or ceramic. Alternatively, a softer material such as bronze or aluminum may also be used.
  • FIGS. 7 and 8 are perspective view drawings of another bearing plate to housing intermediary load structure 152 .
  • Bearing plate to housing intermediary load structure 54 in FIGS. 1-6 was substantially one piece and monolithic.
  • Bearing plate to housing intermediary load structure 152 is comprised of at least two discrete pieces 154 with spaces 158 in between pieces 154 .
  • Five pieces 154 a , 154 b , 154 c , 154 d , 154 e are shown in FIG. 8 though any number of pieces could be used.
  • Pieces 154 may be cylinders, spheres, flattened cylinders, pyramids, etc. An odd number of pieces may make it easier to tune bearing plate to housing intermediary load structure 152 .
  • Pieces 154 may be distributed around a circumference of sleeve 48 , 50 so that each space 158 between each piece 154 is of the same size.
  • Sleeve 48 , 50 may comprise multiple pieces or a single piece.
  • Each piece 154 has an internal arc with a radius of curvature 162 ( FIG. 8 ) that corresponds to or is slightly larger than a radius of curvature 160 of outer housing sleeve 48 , 50 .
  • the inventor has discovered that the tolerance accuracy needed to manufacture monolithic bearing plate to housing intermediary load structure 52 ( FIGS. 1-6 ) is quite high and therefore difficult and expensive to produce. In fact, a high percentage of manufactured pieces may need to be discarded because of the high necessary tolerances. If bearing plate to housing intermediary load structure 52 includes dimensions too far removed from defined tolerances, excess unbalanced pressure may be placed on outer housing sleeve 48 , 50 and then on bearing balls 46 .
  • bearing plate to housing intermediary load structure 152 having multiple pieces 154 .
  • Each piece 154 requires less tolerance accuracy which results in faster, less expensive manufacturing.
  • Pieces 154 are less sensitive to twisting forces applied to outer housing sleeve 48 , 50 .
  • Bearing plate to housing intermediary load structure 152 is less sensitive to out of “roundness” from each piece 154 .
  • Less material is used for bearing plate to housing intermediary load structure 152 and more manufacturing methods are available. Powder metal could be used to manufacture pieces 154 .
  • a retention member 156 (best seen in FIG. 8 ) may be used to affix bearing plate to housing intermediary load structure 152 to outer housing sleeve 48 , 50 .
  • Retention member 156 could be, for example, a flare from each piece 154 , a male extension, a female extension, etc.
  • a corresponding mating retention member 164 may be disposed in outer housing sleeve 48 , 50 .
  • Mating retention member 164 could be, for example, a recess, a female extension, a male extension, etc.
  • Each piece 154 may be pliant and biased toward the position shown in the figures.
  • each piece 154 may be pinched and inserted into recesses 164 of outer housing sleeve 48 , 50 so that flares 156 are bent inwardly. The bias then causes piece 154 to resume the position shown to mate with recesses 158 .
  • sleeve 200 which could be used in accordance with an embodiment of this disclosure.
  • sleeve 200 is split in half axially defining a top part 200 a and a bottom part 200 b .
  • Top and bottom parts 200 a , 200 b may be identical and each form a hollow half cylinder.
  • Pieces 154 of bearing plate to housing intermediary load structure 152 and recess 164 may be disposed in top and bottom parts 200 a , 200 b as discussed above.
  • Walls defining openings 202 may be disposed at distal ends of sleeve 200 to mate with clips 72 of ball retainer segment 54 discussed above.
  • top part 200 a may be placed on top of bottom part 200 b .
  • Top and bottom parts 200 a , 200 b may be strapped together with a strap or clip 204 .
  • a recess 206 may be disposed circumferentially around sleeve 200 to receive strap or clip 204 .
  • Sleeve 200 provides benefits not available in the prior art. For example, sleeve 200 may benefit from lower accuracy requirements during manufacture. Less accuracy requirements result in faster, less expensive manufacturing. Less tolerance for errors in size and shape is required for each part 200 a , 200 b . Further, as top and bottom parts 200 a , 200 b may be identical, only a single type of piece needs to be manufactured. This results is a simplified manufacturing process. Sleeve 200 can handle higher loads in the axial direction than the prior art structures resulting in higher axial strength.

  • FIG. 10A shows a front 214 of sleeve 210 and
  • FIG. 10B shows a rear 216 of sleeve 210 .
  • Sleeve 210 is a single monolithic structure so that no assembly of sleeve 210 is required.
  • Sleeve 210 may further include pieces 154 of bearing plate to housing intermediary load structure 152 and recess 164 .
  • Mating recesses and/or protuberances 212 , 272 may be disposed on sleeve 210 to mate with load bearing plates as discussed below.

  • a linear bearing including sleeve 210 provides significantly greater structural integrity than that available in the prior art.
  • a monolithic structure for sleeve 210 means that the sleeve cannot be disassembled without literally breaking the structure apart. Assembly of a linear bearing including sleeve 210 is simpler than prior art structures because no assembly of sleeve 210 is needed.
