Block bearing sleeve for railway vehicle

Abstract

The railcar is arranged to include two side frames and corbels. Each side frame has axle box openings at each end to accommodate bearing adapters. The bearing nipple arrangement includes a cast steel bearing nipple that is shaped to fit onto the top of the bearing arrangement. Fitted to the top of the bearing nipple is a nipple pad comprising an elastomer of selected durometer. The protrusions extend from the nipple pad and are received in notches in the bearing nipple to provide longitudinal stability to the nipple pad on the bearing nipple itself.

Description

technical field [0001] This invention relates to railroad vehicles, and more particularly to support bearing nipples for use in the axle box cutouts of the side frames of railroad vehicles. Background technique [0002] In a railroad car, the two axles are held in a pair of laterally spaced side frames such that a corbel extends laterally between and bears on each side frame. The wheels are crimped onto the axle so that the end of the axle is also fitted with a rolling bearing arrangement. The rolling bearing arrangement fits itself into bearing sleeves which fit into the axle box cutout openings at the longitudinal ends of each side frame. The bolster ends themselves bear on a spring set which bears on the lower part of the central opening of the side frame. [0003] US Patent No. 5,562,045 discloses a nipple and spacer arrangement useful in fitting a bearing arrangement into the pedestal cutout opening of each side frame. It is to this document that the improvements of ...
