Problems solved by technology

Because the requirements for the bearing speed and strength are very high here, sometimes the bearing is set as a four-point support, but this limits the force that can be transmitted

Embodiment Construction

[0016] The rolling bearing 1 shown in the figure comprises a one-piece bearing ring, the outer ring 2 , and a two-piece bearing ring, the inner ring 3 . A spherical bearing body 4 or 5 made of ceramic material is mounted between the outer ring 2 and the (two-piece) inner ring 3 . Such ceramic rolling elements are known in the prior art. Rolling elements 4 or 5 form rolling element row 6 or 7 respectively.

[0017] In the drawing, rolling bearing 1 is configured as an angular contact ball bearing. The contact areas of the rolling elements 4 , 5 with their respective tracks in the bearing rings 2 , 3 form an angle to the radial direction. The contact angles of the two rolling element rows 6 and 7 are designated α1 or α2 respectively. The contact angle α1 of the first rolling element row 6 lies between 5° and 35°. In contrast, the contact angle of the second rolling element row 7 lies between 10° and 60°.

[0018] It can then be seen that rolling elements 4 , 5 with differen...

Abstract

A double-row roller bearing comprises a one-piece bearing ring, a bearing ring that is split in the axial direction, and rolling bodies that are arranged between the two bearing rings. The rolling body of the first row has a first diameter, and the rolling body of the second row has a second diameter that is different to the diameter of the rolling body of the first row. The rolling bodies consist of a ceramic material, and the contact angle of the first rolling body row is different to the contact angle of the second rolling body row.

Description

technical field [0001] The invention relates to a double-row rolling bearing, which is an integral part of a transmission system. The transmission system produces high speed and high temperature during operation. The double-row rolling bearing includes an integral bearing ring and a Two-piece bearing ring, and the rolling elements mounted between them, wherein the rolling elements of the first row of rolling bearings have a first diameter, and the rolling elements of the second row of rolling bearings have a second diameter, the second diameter is different The diameter of the rolling elements in the first row of rolling bearings. Background technique [0002] Such rolling bearings are described, for example, in GB 152 018. Bearings of this construction are mounted, for example, on high-speed motor vehicles, ie sports cars. In particular, the propeller shafts of sports cars are secured with such bearings. Because the requirements for the bearing speed and strength are ver...
