Multipoint radial bearing, has rolling elements constructed such that contact region with cylindrical mold is provided in middle of rolling elements, where elements are guided on ring by line contact and on another ring over point contacts

摘要

The bearing has rolling elements (4) constructed such that a contact region with cylindrical mold (4'') is provided in middle of the rolling elements and the contact region with convex, spherical geometry (4') is provided at sides of the rolling elements. The rolling elements are guided on a bearing ring (3) by a line contact (7) and on another bearing ring over two point contacts (5, 6). A spacer ring with higher thermal expansion coefficient is mounted between ring halves (1, 2) having a concave groove geometry.
