The roller body, inter alia, for a spherical roller bearing as well as rolling element bearing with the roller body

摘要

It is the object of the invention, the roller body for a spherical roller bearing, for a torodiallager to improve or for a barrel roller bearings. As well as a corresponding roller bearing with improved roller members to be designed.For this purpose, a roller body 1 for a spherical roller bearing, for a toroidal bearings or for a barrel roller bearings is proposed, wherein the roller body 1 in the range of possible contact surfaces, with a running track in the direction of its axis of rotation 3 has a central portion 8 on both sides an end section 9, wherein the total profile curve 5 of the roller body in a longitudinal section through the axis of rotation 3 of the superimposition of a base profile course 6 with a correction profile course of 10 is formed, wherein the base profile course 6 in the form of a segment of a circle with a radius r is formed, and wherein in the region of the end sections 9 of the diameter dw of the roller body 1 in the total profile course of 5 by means of the superposition of the correction profile course of 10 with respect to the base profile course 6 is reduced, and wherein in the middle section 8 of the total profile course of 5 the base profile course 6 corresponds to.
