ROLLING RADIAL BEARING OF GYROSCOPE Russian patent published in 2010 - IPC F16C19/22 F16C33/34 F16C33/36 G01C19/04 

FIELD: machine building.

SUBSTANCE: rolling radial bearing of gyroscope consists of internal and external rings with races, and of placed between them rolling elements made in form of rollers installed in seats of separators. Rollers and made two-stepped. A bigger diametre of the step with one section contacts only the race of the external ring of the bearing. The less diametre of the step made with two sections contacts only races of its internal groove of constant and similar rotation frequency. The race of the internal ring of the bearing has a groove to create a gap with diametre of the bigger step of the roller; the groove is made spherical or barrel shape, while the race of the external ring of the bearing is made spherical. Also ratio of diametr of the bigger step of the roller to diametre of the less step of the roller is equal to 2/1, while number of rollers equals to a prime number, for example five.

EFFECT: reduced noise, increased rotation frequency and service life, elimination of rolling elements skidding on races of bearing rings, increased reliability.
