THRUST-RADIAL MULTI-ROW ROLLING BEARING

摘要

FIELD: .mechanical engineering ^ SUBSTANCE: thrust-radial multi-row rolling bearing comprise at least two rows of rolling bodies of same diameter and same number of pairs of outer and inner races having the same heights and base faces provided with ways with contact points. The radii of the generatrises of the ways are greater than the radius of the generatrix of the rolling bodies. The base faces of the inner and outer races point in opposite directions. The sums of the distances from the contact points of ways of each pair of the outer and inner races to their base faces are equal. ^ EFFECT: simplified structure and prolonged service life. ^ 3 dwg
