摘要:
A wheel end (A-F) or other assembly for facilitating rotation about an axis includes a tubular housing (2), a spindle (20) that extends into the housing, and a double row antifriction bearing (6, 120) between the housing and spindle. The bearing includes at least one separate inner race (50, 126) that fits over the spindle, with the axial position of that race determining the setting for the bearing. Preferably, a spacer (66, 150, 160) fits around the spindle between the inner race and a backing element (30, 48, 60, 110, 132). The assembly is unitized by deforming the end of the spindle outwardly against the end of the separate inner race with the deformation being sufficient to drive the inner race toward the backing element and collapse the spacer, if present. The deformation of the end of the spindle continues until bearing produces a torque that reflects a desired preload in the bearing.
摘要(中):
用于促进围绕轴旋转的车轮端(AF)或其它组件包括管状壳体(2),延伸到壳体中的主轴(20)和在壳体和主轴之间的双列减摩轴承(6,120) 。 轴承包括装配在主轴上的至少一个独立的内座圈(50,126),该座圈的轴向位置决定了轴承的设置。 优选地,间隔件(66,150,160)在内座圈和背衬元件(30,48,60,110,132)之间围绕心轴配合。 组件通过使主轴的端部向外抵抗分离的内圈的端部变形而变形,其变形足以驱动内圈朝向背衬元件,并且如果存在则折叠间隔件。 轴的端部的变形继续,直到轴承产生反映轴承中期望的预载荷的扭矩。
