Abstract

Abstract A full complement bearing roller having an improved retaining end plate and seal, suitable for a carriage roller, a mast roller, a cam roller, a track roller and the like. The outer race is combined with a roller and the outer race or the inner race has an annular groove facing toward the space between the outer and inner races. The retaining end plate is provided with a series of spring lugs which engage in the annular groove, locking the end plate against the ends of the rollers and taking the thrust of the rollers. The end plate also has joined to it as by vulcanizing a rubber-like seal which engages the opposite radial member (inner or outer race) from the lugs. In the preferred embodiment the seal also fills the space between the lugs so as to complete the protection.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 232 words
A self-contained antifriction roller comprising an outer track roller having on the inside a roller bearing race, an inner bearing race opposite from the outer bearing race and within it, a plurality of full complement bearing rollers riding on the outer race and the inner race, an annular locking recess on the end of one of the races facing toward the other race beyond the end of the bearing roller, a resilient metallic end plate having a ring portion contacting the ends of the bearing rollers and supporting thrust loads on the outer race of rollers against the inner race in both directions, having adjoining the locking recess and disposed away from the bearing rollers a plurality of annularly distributed metallic spring lugs which protrude from the ring and which engage in the recesses, the lugs having their greatest depth remote from the end of the bearing rollerS and tapering to a minimum depth adjoining the end of the bearing rollers, and rubber-like material adhering to the end plate, intruding between the lugs, and forming with the lugs a continuous seal at the locking recess and having at the opposite end a molded on annular lip extending continuously around the circumference and engaging and sealing on the race opposite to the race which has the locking recess, the rubber-like material being omitted from the ring at the end adjoining the bearing rollers.
Claim 2
Dependent Claim 232 words
A self-contained antifriction roller comprising an outer track roller having on the inside a roller bearing race, an inner bearing race opposite from the outer bearing race and within it, a plurality of full complement bearing rollers riding on the outer race and the inner race, an annular locking recess on the end of one of the races facing toward the other race beyond the end of the bearing roller, a resilient metallic end plate having a ring portion contacting the ends of the bearing rollers and supporting thrust loads on the outer race of rollers against the inner race in both directions, having adjoining the locking recess and disposed away from the bearing rollers a plurality of annularly distributed metallic spring lugs which protrude from the ring and which engage in the recesses, the lugs having their greatest depth remote from the end of the bearing rollerS and tapering to a minimum depth adjoining the end of the bearing rollers, and rubber-like material adhering to the end plate, intruding between the lugs, and forming with the lugs a continuous seal at the locking recess and having at the opposite end a molded on annular lip extending continuously around the circumference and engaging and sealing on the race opposite to the race which has the locking recess, the rubber-like material being omitted from the ring at the end adjoining the bearing rollers.
Claim 3
Dependent Claim 21 words
A roller of claim 1, in which the locking recess is in the track roller and the lugs engage in it.
Claim 4
Dependent Claim 21 words
