Toroidal spacer

摘要

The present invention relates to a spacer device for roller elements in a toroidal roller bearing, and a method for manufacturing a toroidal roller bearing comprising a plurality of spacer devices. The toroidal roller bearing allows for axial and angular displacement between an inner and outer bearing ring. The spacer device provides first and second roller-contacting surfaces having a concave shape adapted to conform with respective convex contacting surfaces of the toroidal roller elements, and at least one axial end portion which is elastically deformable.

主权项

1. A spacer device for roller elements in a toroidal roller bearing having an inner and an outer ring, wherein the toroidal roller bearing allows for axial and angular displacement between the inner and outer ring, the spacer device comprising:
a first and second roller-contacting surface on opposite sides of the spacer device, wherein the first and second roller-contacting surfaces are arranged to separate two adjacent toroidal roller elements in a tangential direction of the bearing, wherein each of the first and second roller-contacting surfaces has a concave shape adapted to conform with respective convex contacting surfaces of the toroidal roller elements, and wherein at least one axial end portion of the spacer device is elastically deformable, the axial end portion including at least a portion of the first and second roller-contacting surfaces.
