FIELD: mechanical engineering; shaft and axle supports. ^ SUBSTANCE: proposed combination bearing designed for operation under rolling friction and dry or semidry sliding conditions has outer race with friction path along which balls move being uniformly arranged over circumference and installed in cage, and inner race with path. Inner race has at least flange at one side of outer end face side of which and also on inner working surface of inner race antifriction self-lubricating coating is found, implementing at friction with counter body, selective transfer effect (no-wear effect) at friction with counterbody. Said antifriction self-lubricating coating is made in form of composition in which technical cloth is used as reinforcement member containing fibers for instance of Teflon and arymide and impregnated with binder and running in layer implementing effect of selective transfer (no-wear effect) at friction with counterbody of pair, for instance, axle or shaft. ^ EFFECT: provision of combination bearing featuring increased service life, operating at slow speeds and higher loads under abrasive wear conditions. ^ 2 cl, 1 dwg |
