Description
Technical field
The utility model relates to technical field of bearings, particularly relates to a kind of 160km/h AC transmission electric power locomotive driving bearing.
Background technique
At present, 160km/h AC drive locomotive being in great demand at home, and the bearing on locomotive all adopts imported bearing, supply falls short of demand for imported bearing, and cost is high, and this bearing production domesticization research has been put on the agenda by country.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of 160km/h AC transmission electric power locomotive driving bearing, and the bearing solved on locomotive all adopts imported bearing, and supply falls short of demand for imported bearing, and the problem that cost is high.
For solving the problems of the technologies described above, the technical solution of the utility model is: 160km/h AC transmission electric power locomotive driving bearing, comprise outer ring, keep stand, retainer lid, roller and inner ring, maintenance stand is cirque structure, keep stand offers several pocket holes, pocket is placed with roller in hole, retainer lid is fixed on the side keeping stand by rivet, roller is placed in outer ring raceway, the both sides of outer ring are equipped with rib and rib contacts with the both ends of the surface of roller, outer ring, rivet, keep stand, retainer lid, roller forms cup roller group, inner ring is placed in cup roller group.
Further, inner ring be provided with rib and rib contacts with a side end face of roller, the another side of inner ring contacts with back-up ring and back-up ring contacts with the opposite side end face of roller.
The utility model structural design advantages of simple, manufacture cost is extremely low, can substitute imported bearing completely, is that country saves foreign exchange, for locomotive works solve imported bearing inadequate supply and the high difficult problem of cost.
