Abstract
A ball bearing having first and second races and, disposed in a gap between the two races, a row of balls of radius Rthat roll along facing tracks of the two races, wherein centers of the balls move on a circular path surrounded by a torus circumscribing all the balls of the row and having the toroidal radius R, a toroidal angle coordinate φ, and a poloidal angle coordinate θ, wherein each track has with each ball two nearly punctiform contact areas P, P; PPat respective contact angles θ, θ; θand θ, wherein the cross section of the track in the region of the contact points P. . . Phas a finite transverse radius of curvature R. . . R, with R>R, and wherein in the vicinity of a contact point P. . . Pthe transverse radius of curvature (R) is a continuous and differentiable function of the poloidal angle coordinate θ: R=R(θ) that increases outward from the respective contact point P. . . Pin both poloidal directions: R(θ)≧R(θ).
