ASSEMBLY METHOD OF BEARINGS OF PURE ROLLING ON BASIS OF STANDARD ROLLING BODIES Russian patent published in 2012 - IPC F16C19/55 F16C25/06 F16C19/02 F16C19/22 

FIELD: machine building.

SUBSTANCE: assembly method of bearings of pure rolling on basis of standard rolling bodies consisting of two-tier bearings with rolling bodies, which are installed in sockets of separator, which contact raceways: in upper tier, with raceway of outer race and external raceway of intermediate race of bearing, in lower tier, with internal raceway of intermediate bearing race and raceway of internal bearing ring consists in the fact that assembly of rolling bodies with raceways is performed with preloading, for example equal to "0". Also, assembly depending on operating conditions with a gap equal for example to +4 to +8 mcm is allowed. For bearings of spindles of high-speed machines, a radial gap, for example, of +0.50 to +0.25 mcm is chosen.

EFFECT: reduction of friction coefficient, vibrations and noise level; provision of pure rolling without sliding and slipping of rolling bodies; increase in rotation frequency, load-carrying capacity and durability of rolling bearings, and improvement of operating reliability and safety of friction assemblies.
