Abstract

The invention discloses a high-speed angular contact bearing and relates to a bearing. The high-speed ball bearing solves the problems that when an existing high-speed ball bearing is used in a compact engine, the bearing is unreliable, and the bearing is prone to loosing in the assembling process. A first inner ring (4) and a second inner ring (5) are arranged side by side from left to right and connected through an inner diameter clamp (6), a plurality of rolling bodies (3) are installed on the first inner ring (4) and the second inner ring (5) through a retainer (2), a groove ring (1) is installed on the retainer (2) and the rolling bodies (3), and a U-shaped groove (1-1) is formed in the outer side wall, corresponding to an oil inlet hole, of the groove ring (1). An annular groove (1-2) is formed in one side of the U-shaped groove (1-1) and located on the outer side of the U-shaped groove (1-1). And the inner diameter of the two half inner rings is additionally provided with grooves for fixing through inner diameter clamps, and it is guaranteed that the bearing is not loosened in the using process. The invention is applied to the engine in a highly rotating environment.

Description

technical field [0001] The invention relates to a bearing, in particular to a high-speed angular contact bearing, in particular to a novel high-speed angular contact ball bearing with an inner ring with an oil return structure and an outer ring with a spring support-extrusion oil film structure. Background technique [0002] In today's mainstream engines, in order to reduce the vibration of the engine, reduce the weight of the bearing, facilitate installation, and improve reliability, it is necessary to add an elastic support structure to the bearing. At present, two methods are mainly used for the design of the elastic support structure. One is the bearing and the elastic support. The structure is designed, processed and manufactured separately, and then integrated, and the other is the integrated design of elastic support and bearing. The separate processing of the spring and the bearing will increase the cumulative error of the two, so it is necessary to carry out an inte...
