Abstract
Official abstract text for this publication.
A cross shaft joint includes a bearing cup, a cross shaft, and a joint yoke. The bearing cup includes a cylindrical portion in which an opening portion for receiving a shaft portion is formed in one end of the cylindrical portion in an axis direction, and a bottom portion that closes the other end of the cylindrical portion in the axis direction. The bearing cup is press-fitted into the fitting hole and supports the shaft portion through a rolling element so that the shaft portion is able to rotate. The bearing cup is fitted onto the shaft portion inside the fitting hole and holds the rolling element with the shaft portion. A diameter of an inner peripheral surface of the cylindrical portion is smaller on the opening portion side than the bottom portion side in a free state of the bearing cup before being press-fitted into the fitting hole.
First claim
Opening claim text (preview).
What is claimed is: 1. A bearing cup of a cross shaft joint, the cross shaft joint including a cross shaft having four shaft portions arranged in a cross shape; and a joint yoke having fitting holes into which the four shaft portions are respectively fitted, the bearing cup comprising: a cylindrical portion, in which an opening portion for receiving a shaft portion of the four shaft portions is formed in one end of the cylindrical portion in an axis direction; and a bottom portion that closes the other end of the cylindrical portion in the axis direction, wherein the bearing cup is adapted to be press-fitted into the fitting hole and supports the shaft portion through a rolling element so that the shaft portion is able to rotate, the bearing cup is adapted to be fitted onto the shaft portion inside the fitting hole and adapted to hold the rolling element with the shaft portion, a radial direction diameter of an inner peripheral surface of the cylindrical portion is smaller on the opening portion side than the bottom portion side in a free state of the bearing cup before being press-fitted into the fitting hole, and the diameter of the inner peripheral surface of the cylindrical portion is gradually reduced from the bottom portion to the opening portion in the free state. 2. The bearing cup according to claim 1 , wherein a part of an inner surface of the bottom portion is bulged towards an inner space of the cylindrical portion.
