ROLLING BEARING Russian patent published in 2009 - IPC F16C19/34 F16C33/58 

FIELD: mechanical engineering.

SUBSTANCE: invention refers to the field of mechanical engineering and may be used in assemblies with pretension at high rotation speeds. The rolling bearing contains outer and inner rings with tapered bearing races, thrust board on one of them which is provided with facility for unloading rolling bodies from operating load in the form of local recession of thrust board working surface (the length of thrust board is defined by formula) and tapered rolling bodies located between the rings. Facility for unloading rolling bodies from operation load has the shape of surface cross section of which is curved line defined by equation: where a - free term, a=s; b - coefficient, s - maximum depth of facility for unloading rolling bodies from operation load, d_max - the largest diametre of bearing race of inner or outer ring.

EFFECT: gradual unloading of rolling bodies from operation load and sliding friction, improvement of lubrication conditions, lowering vibration and noise of rolling bearing operation.
