Abstract

The invention relates to the area of production and operation of bearings and can be used at production of roller bearings, operation and repair of those. In the roller bearing that includes the outer and the inner rings with the rollers placed between those the working surfaces of the sides of the outer and inner rings are arranged as sections of surface of a tore in such a way that they smoothly go to surfaces of recesses provided on the working cylinder surfaces of the rings, at that the distance between the plane of symmetry of spherical surface of the end of the roller and the surfaces of the tore for the outer and the inner rings is related to the radii of those surfaces and the distance of the points of contact of those with the working cylindrical surface of the rings with dependence: l=(d/2-h)(R/R1-1), where l - distance between the plane of symmetry of spherical surface of the edge of the roller and the surfaces of the tore ; d - diameter of the roller; R - radius of surface of the tore; R1 - radius of spherical surface of the edge of the roller; h - distance of the point of contact of working surfaces of the edges of the rings with the edges of the rollers from the working cylinder surface of the rings. Besides that, in the roller bearing the ratio of the value of radius R of surface of the tore to the value of radius R1 of spherical surface of the edge of the rollers is chosen as mainly equal to R/R1=1,1…1,25. Such construction of the roller bearing provides substantial increase of its reliability and durability (resource).
