METHOD FOR DETERMINATION OF BASIC STATIC CARRYING CAPACITY OF ROLLER FRICTIONLESS BEARING

摘要

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 consists in the fact that in suggested method for determination of basic static carrying capacity of roller frictionless bearing, and the method consists in the fact that in bearing roller diameter D_w is measured, as well as length L of roller and rolling path contact, number of rows i and number of rollers z are measured in one row, nominal angle α of bearing contact is also measured, and then basic static carrying capacity of roller frictionless bearing is determined, at that radiuses of bearing rings rolling paths curvature (or parts that replace them) are measured, and the least reduced curvature radius R_red.min is determined with account of roller diameter in contact of roller 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.;3 cl
