Rollerbearing for machinery comprises cage and races for rollers using cage roller pockets and specified circumferential surfaces and cage and race axial lengths to limit cage offset

摘要

The cylindrical rollers (6) ride between inner and outer races and lie in interposed cage (1) pockets giving a rollerbearing to this specification 1.5*10-3D = H = 9.0*10-3D and A/B = 0.6-1.0. In this, (D) is the diameter, (H) the dimension of the ring gap between cage surface and race surround surface, i.e. the inner diametral surface of an outer race rib (4) or the outside diametral surface of the inner race in relation to the cage circumference. (A) is the axial length of the circumferential cage surface and (B) is the length of the circumferential race surface. The cage has a roller guiding surface (7) in the axial direction of the spherical sector (8). The radial offset of the cage is limited by each cage and roller engagement.
