Abstract
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.
Claims19
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.
A toroidal roller bearing which allows for axial and angular displacement, the toroidal roller bearing having a plurality of spacer devices 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 comprising at least a portion of the first and second roller-contacting surfaces.
A method for manufacturing a toroidal roller bearing having a plurality of roller elements arranged between respective raceways of an inner and an outer ring, wherein the toroidal roller bearing allows for axial and angular displacement between the inner and outer ring,
- the toroidal roller bearing further comprising a plurality of spacer devices each having a first and second roller-contacting surface on opposite sides, which first and second roller-contacting surfaces being arranged to separate two adjacent roller elements in a tangential direction of said bearing, the method comprising,
- mounting the plurality of roller elements and the plurality of spacer devices by insertion between the inner and outer ring, which insertion comprises compressing at least one axial end portion of at least one spacer device between the two adjacent roller elements.
