ROLLER BEARING Russian patent published in 2017 - IPC F16C19/22 F16C33/34 F16C33/58 

FIELD: machine engineering.

SUBSTANCE: roller bearing comprises at least one outer and one inner ring (4) having at least one bead with beveled at an angle ϕ° working surface (3), technological groove connecting the working surface (3) side raceway (6) and rollers (1) arranged between the rings (4). The surface (3) is smoothly connected to the groove bottom surface and the working surface (2) supporting the ends of the rollers are spherical. The position of point of contact surfaces (2) of the rollers (1) with a surface (3) of boards defined by the relationship with the sin ϕ°= tg ϕ° where L - surface distance of the contact point (2) with a surface (3) before forming the raceway ring (4), mm; d - the external diameter of the roller (1) from the surface (2) mm; H - molded depth of the ring (4), mm; e - the value of the surface (3), mm; R - radius of curvature of the surface (2) mm; ϕ° - angle of taper surface (3), degrees, which is selected in the range 010°'<ϕ°<2°. Chamfer at the roller (1) from the end face of the support are formed as blunt the sharp edge rounding with a radius not more technologically possible, resulting in a known manner.

EFFECT: maximum decrease sliding friction in the contact zone between the ends of the rollers with flanges rings, reducing thereby the work of friction, heating of the bearings and enhance their service life, by increasing the contact area raceway rings by narrowing process grooves in the raceway rings and rolling surfaces of rollers can reduce contact stress on the working surfaces of rings and rollers, bearings increased load capacity approximately.
