AXIAL NEEDLE ROLLER BEARING WITH SELF-ALIGNING WASHERS

摘要

An axial needle roller bearing assembly is provided having first and second axial end washers, each with a radial body having a concave outer profile and a convex inner profile in radial cross-section and each including an axial flange on one of a radially inner or outer side. First and second intermediate washers having respective intermediate radial bodies with first and second axial sides are provided with the first axial sides defining first and second bearing races and the second axial sides defining contact surfaces for the respective first and second axial end washers. A cage and roller assembly is located between the first and second bearing races, and includes a cage with a plurality of radially extending needle roller pockets, and a plurality of needle rollers received in at least some of the pockets.

1. An axial needle roller bearing assembly, comprising:
a first axial end washer having a first radial body with a concave outer profile and a convex inner profile in radial cross-section, and a first axial flange on one of a radially inner or outer side; a second axial end washer having a second radial body with a concave outer profile and a convex inner profile in radial cross-section, and a second axial flange extends from the second radial body on the other of the radially inner or outer side from the first axial flange, and the first and second axial flanges extending in an axial direction toward one another; a first intermediate washer having a first intermediate radial body with a first axial side and a second axial side, the first axial side defining a first bearing race and the second axial side defining a flat surface in contact with the first axial end washer; a second intermediate washer having a second intermediate radial body with a first axial side and a second axial side, the first axial side defining a second bearing race and the second axial side defining a flat surface in contact with the second axial end washer; and a cage with a plurality of radially extending needle roller pockets, and rollers received in at least some of the pockets that roll against the first and second bearing races.
