METHOD FOR DETERMINATION OF BASIC STATIC CARRYING CAPACITY OF BALL FRICTIONLESS BEARING Russian patent published in 2009 - IPC G01M13/04 

FIELD: physics, measurement.

SUBSTANCE: invention is related to machine building and may be used, in particular for determination of basic static carrying capacity (permissible static load) of machine bearing units with frictionless bearings. Method for determination of basic static carrying capacity of ball frictionless bearing consists in the fact that in bearing ball diameter D_w is measured, number of rows i and number of balls z are measured in one row, nominal angle α of bearing contact is also measured, and then basic static carrying capacity of ball frictionless bearing is determined. At that radiuses of bearing rings rolling paths curvature are measured in sections by two planes of the main curvatures, and the least reduced curvature radius R_red.min is determined with account of ball diameter in contact of ball and rolling paths of bearing rings, the least value of plastic hardness HD_min is determined for rolling path of bearing ring, limit even deformation ε_p is defined for material of bearing ring rolling path, which has the least value of plastic hardness, the least value of index of resistance to bearing rings material to contact elastoplastic deformation according to formula

EFFECT: higher accuracy of roller frictionless bearing basic static carrying capacity determination.
