Document Type and Number:
Japanese Patent JP2019052718
Kind Code:
A
Abstract:
To provide a thrust roller bearing which can suppress wear by reducing a contact force between a roller rolling face and roller stop parts of pockets of an inner cage and an outer cage at the rotation of the bearing.SOLUTION: A thrust roller bearing comprises: a plurality of rollers which are arranged between a fixed-side raceway surface formed at a non-rotation member and a rotation-side raceway surface formed at a rotation member; an annular inner cage having pockets for rollingly accommodating a plurality of the rollers in a peripheral direction in a plurality of points in the peripheral direction; and an annular outer cage externally fit and connected to the inner cage, and having pockets for accommodating a plurality of the rollers in the peripheral direction in a plurality of points in the peripheral direction. In each of the pockets of a plurality of relatively-opposing pairs in an axial direction, a pocket end face of the pocket which is arranged outside in the radial direction so as to oppose the rotation-side raceway surface is located inside the radial direction of the pocket which is arranged so as oppose the fixed-side raceway surface rather than the pocket end face at the outside of the radial direction.SELECTED DRAWING: Figure 1
