Abstract
A linear roller bearing having a rolling body circulating shoe (15) including end-arranged attachment elements (16) as a lubricating device, wherein each attachment element contains a volume (9) for storing lubricant and transferring lubricant to a rail that guides the circulating shoe. According to the invention, the attachment element is formed from an inner housing shell (8b), which lies against the head piece (4) of the support body (1) of the circulating shoe, and an outer housing shell (8a), which faces away from the support body, which housing shells can be fastened to the head piece of the support body by a central screw (17).
Claims16
A linear roller bearing, comprising:
- a roller body circulating shoe that includes a support body with a head piece at each end,
- a first attachment element arranged on one of the ends as a lubricating device,
- said first attachment element includes a cavity defining a volume for lubricant storage and lubricant transfer to a rail guiding the circulating shoe,
- the first attachment element is centered and rotationally locked on one of the head pieces via:
- (i) a portion of one of the head pieces defines an arcuate surface that abuts a complementary arcuate surface formed on the first attachment element, and (ii) insertion of the portion of one of the head pieces inside of the first attachment element,
- the first attachment element comprises an inner housing shell that contacts the head piece of the support body of the circulating shoe and an outer housing shell facing away from the support body, said inner and outer housing shells are mounted by a central screw on the head piece, and
- the central screw is guided through passage holes that are aligned with each other in the outer housing shell and the inner housing shell.
An attachment element for a linear roller bearing including a roller body circulating shoe with a support body with a head piece at each end used for lubricating a running rail, the attachment element comprising:
- a housing formed by:
- an inner housing shell that is adapted dimensioned to contact the head piece such that the housing is centered and rotationally locked on the head piece via:
- (i) a portion of one of the head pieces defines an arcuate surface that abuts a complementary arcuate surface formed on the first attachment element, and (ii) insertion of the portion of the head piece inside of the first attachment element, and
- an outer housing shell that is dimensioned to face away from the support body, said inner and outer housing shells are dimensioned to be mounted by a central screw on the head piece,
- a cavity located in the housing that defines a volume for lubricant storage and lubricant transfer to a rail guiding the circulating shoe,
- the central screw is guided through passage holes that are aligned with each other in the outer housing shell and the inner housing shell, and
- a lubricant transfer element in communication with the cavity and dimensioned to contact the running rail.
