摘要： A linear motion bearing assembly as provided for movement along a shaft. The ball retainer of the bearing assembly is assembled from a plurality of arcuate interengageable self-contained ball retainer segments. Preferably, the plurality of segments are all identical and can be assembled to a variety of configurations for either open-type bearing assemblies or closed-type bearing assemblies. Each of the ball retainer segments includes at least one ball track having a load bearing portion and a return portion. These segments are preferably formed of an engineering polymer and are substantially self-contained to protect the bearing balls contained therein from ambient contamination. At least one load bearing plate is axially positioned in each segment and serves to receive and transmit loads from the bearing balls in the load bearing portion of the ball tracks. The load bearing plates are preferably retained in the segments to facilitate ease of assembly and to eliminate the need for an outer housing. The segments are joined together to form the overall bearing assembly either through interlocking structure formed on each segment or by retainer clips or bands. Optionally, end seals may be positioned on the longitudinal ends to protect the bearing assembly from ambient contamination. A novel and efficient assembly process is also provided for linear motion bearing assemblies. This process includes the steps of providing a plurality of arcuate self-contained ball retainer segments, each of said segments including at least one ball track having a load bearing portion and a retainer portion; loading a plurality of bearing balls into the ball track; positioning a load bearing plate in the segment adjacent the load bearing portion of the ball track; and assembling the arcuate self-contained ball retainer segments to form a linear motion bearing assembly.

摘要： A linear motion bearing assembly is provided and includes ball retainer structure, outer housing sleeves, a plurality of load bearing plates and plate retainer structure. The ball retainer structure of the bearing assembly can be either monolithically formed or, alternatively, assembled from multiple elements. At least a portion of axial ball tracks are formed in the outer radial faces of the ball retainer structure with each ball track having a load bearing portion providing access to a support shaft or spline. An outer housing including a pair of sleeves are provided to encompass and protect the ball retainer structure and the bearing balls contained therein. These sleeves are preferably formed of an engineering plastic. A plurality of load bearing plates, preferably of the self-aligning type, are positioned within the outer housing and serve to receive and transmit loads from the bearing balls in the load bearing portion of the ball tracks. Separate plate retainer structure is configured and positioned to directly receive and transmit loads from the load bearing plates to a carriage into which the bearing assembly is mounted. This plate retainer structure may be extended longitudinally to substantially enclose the exterior surface of the ball retainer structure. In this configuration, no separate outer housing structure is needed.

摘要： A linear motion ball bearing is disclosed for providing relative linear motion in combination with a shaft. A housing has an axially elongated opening therethrough and an axially elongated generally tubular shaped ball retainer is positioned within the housing opening and defines a plurality of endless ball loops therein extending generally in the axial direction of the retainer. The retainer has a radially inner surface and a radially outer surface and the ball loops are spaced generally circumferentially about the retainer. Each loop contains a plurality of balls and has a first ball duct for a row of loaded balls and a second ball duct for a row of unloaded balls. Each first ball duct is open through the radially inner and radially outer surfaces of the cage, and each ball loop is arranged with the first ball duct next adjacent the first ball duct in the adjacent ball loop along one axially extending side and the second ball duct therein adjacent the second ball duct in the next adjacent ball loop along the other axially extending side. The housing defines a land opposite each pair of adjacent first ball ducts and extending radially inward, each land extending sufficiently radially inward and being of sufficient circumferential dimension to support the loaded balls of adjacent pairs of the first ball ducts and having a contoured relatively smooth surface for accommodating the loaded balls positioned within the corresponding opposed pair of respective first ball ducts of respectively adjacent ball loops. A uniquely shaped complex ball support surface connects each pair of ball ducts while maintaining constant floor to ceiling height about the balls to provide smooth, quiet operation of the bearing so as to combine with the uniform loaded ball arrangement to provide a unique bearing having improved load life performance and substantially quiet characteristics, while simplifying the manufacturing procedures.
