Abstract
An end block defining a part of a slider of a linear motion guide unit is provided. The end block includes a rib structure fabricated in a desired shape from a first resin material by injection molding. The rib structure is provided with a rib system including a plurality of ribs, preferably, arranged in the form of a grid to thereby define a plurality of void spaces or recesses and also with at least one curved connecting path section of an endless circulating path provided in the guide unit. A filing material preferably of a second resin material is provided in at least one of the plurality of recesses. The second resin material preferably has a viscous characteristic after hardening.
Claims20
An end block for use as a part of a slider of a linear motion guide unit, comprising:
- a rib structure of a predetermined shape and comprised of a first resin material, said rib structure including at least one curved connecting path section of an endless circulating path provided in said guide unit and a rib system which defines a plurality of recesses;
- and
- a filling material provided in at least one of said plurality of recesses.
A linear motion guide unit, comprising:
- a rail extending over a length;
- a slider slidably mounted on said rail, said slider including a center block and a pair of end blocks each fixedly attached to a corresponding end of said center block, each of said end blocks including a rib structure provided with a plurality of recesses and a filling material provided in at least one of said plurality of recesses;
- and
- a plurality of rolling members interposed between said rail and said slider.
An end block for use as a part of a slider of a linear motion guide unit, said end block comprising:
- a rib structure of a predetermined shape and comprised of a first resin material suitable for use in injection molding, said rib structure including at least one curved connecting path section of an endless circulating path provided in said guide unit and a rib system which defines a plurality of recesses;
- and
- a filling material provided in at least one of said plurality of recesses;
- wherein said filling material includes a second resin material different from said first resin material, and wherein said second resin material is a viscous resin material which has a viscous characteristic after hardening.
