BEARING ASSEMBLY

摘要

A bearing assembly includes first and second rolling-element bearings each having an inner ring with a running surface for rolling elements and a guide flange that extends radially outwardly beyond the running surface for limiting axial movement of the rolling elements. The inner rings are configured such that they are in contact with each other exclusively within a contact surface diameter that is smaller than an average value of a maximum diameter of the running surface of one of the inner rings and a maximum outer diameter of that inner ring. The guide flanges are disposed on sides of the inner ring of the first rolling-element bearing and of the second rolling-element bearing that face each other axially.

1. A bearing assembly comprising:
a first rolling-element bearing including an inner ring that is connectable to a shaft for rotation therewith, the inner ring of the first rolling-element bearing having a running surface for rolling elements of the first rolling-element bearing; and a second rolling-element bearing including an inner ring that is connectable to the shaft for rotation therewith, the inner ring of the second rolling-element bearing having a running surface for rolling elements of the second rolling-element bearing, wherein the inner ring of the first rolling-element bearing and the inner ring of the second rolling-element bearing are configured such that the inner ring of the first rolling-element bearing and the inner ring of the second-rolling element bearing are in contact with each other exclusively within a contact surface diameter, the contact surface diameter being smaller than an average value of a maximum diameter of the running surface of the inner ring of the first rolling-element bearing and a maximum outer diameter of the inner ring of the first rolling-element bearing, and the contact surface diameter being smaller than an average value of a maximum diameter of the running surface of the inner ring of the second rolling-element bearing and a maximum outer diameter of the inner ring of the second rolling-element bearing, the inner ring of the first rolling-element bearing and the inner ring of the second rolling-element bearing being disposed directly adjacent to each other, wherein the inner ring of the first rolling-element bearing includes a guide flange which extends radially outward over or beyond the running surface of the inner ring of the first rolling-element bearing, the guide flange being configured to axially limit a movement of the rolling elements of the first rolling-element bearing, and wherein the inner ring of the second rolling-element bearing includes a guide flange which extends radially outward over or beyond the running surface of the inner ring of the second rolling-element bearing, the guide flange of the second rolling-element bearing being configured to axially limit a movement of the rolling elements of the second rolling-element bearing, and wherein the guide flange of the inner ring of the first rolling-element bearing and the guide flange of the inner ring of the second rolling-element bearing are disposed on sides of the inner ring of the first rolling-element bearing and of the second rolling-element bearing which face each other axially.
