FIELD: mechanical engineering. SUBSTANCE: invention relates to bearings of shafts and axles. Proposed combination support consists of inner race 1 and outer race 2, rolling elements 3, outer race inserts 4, inner race inserts 5, rolling element inserts 6 and step bearing 7. load bearing hydrodynamic layers of lubricant are formed operation between mating surfaces of inner race 1 and outer race 2 with sliding inserts 5 and 4, respectively. Sliding inserts 6 provide liquid friction in mating with rolling elements 3. Step bearing 7 serves for self-alignment of sliding inserts. EFFECT: reduced wear of combination support. 3 cl, 3 dwg |
