摘要:
An inner ring (6) is configured to simultaneously ensure the strength thereof and the dimensional accuracy of a female spline portion of a shaft hole (22) thereof in the case where the female spline portion (23) is subjected to heat treatment. Also it is configured to suppress the backlash of spline fit with a shaft (12). The inner ring (6) is mounted in a constant velocity universal joint for transmitting torque while the inner ring (6) is allowed to be angularly displaced relative to an outer ring (3) and is spline-fitted to a shaft (12) inserted into a shaft hole (22) formed through the inner ring (6). The inner ring (6) has a hardened layer by means of heat treatment which is formed only in an axial central portion (29) of the shaft hole (22), but is not formed in remaining inner diameter surface other than the axial central portion (29).

A wheel drive unit comprises a bearing unit for wheel drive which is light in weight and low in cost. The components constituting the bearing unit for wheel drive have optimum properties to secure the durability thereof. Of the components constituting the bearing unit for wheel drive, the portions indicated by a diagonal grid hatching are quench-hardened with the other portions being not quench-hardened and left as they are, whereby the rolling fatigue life and wear-resistance of the components are improved and cracking is prevented.

A retaining ring and method of installation are provided to maintain the relative position of an inner joint to an outer joint in a constant velocity joint. The outer joint (14) has an open end, a generally spherical internal surface with a plurality of ball grooves (30), and an annular groove (20) formed in the internal surface near the open end of the outer joint (14). An annular ring (18) with a radially extending tab (22) is aligned within one of the ball grooves (30) to axially align the tab (22) with the annular groove (20). The annular ring (18) is then rotatable within the annular groove to align the tab (22) between two of the ball grooves (30). The annular ring (18) is rotationally retained within the annular groove (20).
摘要:
Die Erfindung betrifft ein Verfahren zur Fertigbearbeitung von für Gleichlaufgelenke bestimmten Kugelkäfigen (1), die mit kugelringförmigen inneren und äußeren Lagerflächen (3, 2) und Kugeltaschen (4) für die Aufnahme von drehmomentübertragenden Kugeln versehen sind. Um die Fertigbearbeitung solcher Kugelkäfige (1) schnell, kostengünstig und möglichst vollautomatisch durchführen zu können, wird erfindungsgemäß vorgeschlagen, daß die Fertigbearbeitung sowohl der inneren und der äußeren kugelringförmigen Lagerflächen (3, 2) als auch der einander in Achsrichtung gegenüberliegenden Anlageflächen (5) der Kugeltaschen (4) für jeweils eine Kugel durch eine Drehbearbeitung erfolgt.
