Title: (EN) METHOD FOR ASSEMBLING CRUCIFORM UNIVERSAL JOINT, AND CRUCIFORM UNIVERSAL JOINT
Abstract: front page image
(EN)

After a cup bearing (13a) is incorporated into a circular hole (11c) of a coupling portion (10c) forming a yoke, a notch (25) having a V-shaped cross section is formed in a portion near the periphery of the circular hole (11c) on an outer side surface of the coupling arm portion (10c). Thereafter, a thin-walled portion (27) having a substantially trapezoidal cross section formed in a radially inner portion of the notch (25) in an opening edge portion of the circular hole (11c) is plastically deformed inward in a radial direction to form a staking portion (14a). Therefore, it is possible to achieve a method of assembling a joint cross type universal joint and a joint cross type universal joint which can form the staking portion for preventing the cup bearing from falling off without complicating the staking work.
