ROLLER BEARING Russian patent published in 2017 - IPC F16C19/38 F16C33/34 F16C33/60 B61F15/12 

FIELD: machine building.

SUBSTANCE: bearing comprises rollers, external and internal rings with toroidal races. Axis of symmetry of race profile is located relatively to plane of symmetry of the bearing at a contact angle close to angle of action on the bearing of the resulting load. The races have round profile with radius , and diameters of sides of the external rings are determined from the ratio D_b≥D_d⋅(1-α⋅Δt), where R is radius of profile of races, mm; L_d is length of work part of races, mm; β is angle of inclination of the axis of symmetry of the races profile relatively to plane of symmetry of the bearing, rad.; D_b is diameter of side of the bearing, mm; D_d is diameter of races of the external ring, mm; α is coefficient of linear expansion of the external ring material, 10^-6/°C; Δt is permitted heating temperature of the external ring.

EFFECT: increased load capacity of the bearing, reliable operation of the bearing, decreased overall dimensions of the bearing, and simplified design.
