High-speed bearing retainer

Abstract

The invention discloses a high-speed bearing retainer. The high-speed bearing retainer comprises a frame body, a plurality of pockets arranged at the upper end of the frame body and a ring groove formed in the bottom of the frame body, concave-up arc surfaces are arranged at the bottoms of connecting parts between every two adjacent pockets, lubricating grease accommodating cavities are formed inthe connecting parts, bottom openings of the lubricating grease accommodating cavities are located in the ring groove, and oil grooves are formed in the inner surfaces of the pockets. The connecting parts are divided into upper parts and lower parts, the lower parts have the same thickness as the frame body, the upper parts are thinner than the lower parts, and the upper parts and the lower partsforms a step outside the connecting parts, and oil guide holes communicating with the corresponding lubricating grease accommodating cavities on the lower part are formed in the step. According to thehigh-speed bearing retainer, through the design of the arc surfaces, the step and the oil guide holes, the high-speed bearing retainer has the advantages of reducing own weight, shifting up the center of mass and enhancing the lubricating effect while the strength of pocket claw mouths is ensured to the greatest extent, the weight is reduced, the lubricating effect is improved, the strength and stability of the pockets are ensured, and problems such as relatively large deformation are solved.

Description

technical field [0001] The invention belongs to a bearing cage, in particular to a high-speed bearing cage. Background technique [0002] Bearings are an important rotating support component in contemporary mechanical equipment. Its main function is to support the mechanical rotation, reduce friction during its movement, and ensure its rotation accuracy. The cage (that is, the bearing cage, also known as the bearing cage) refers to the bearing parts that partially wrap all or part of the rolling elements and move with them, to isolate the rolling elements, and usually guide the rolling elements and keep them in the bearing Inside. [0003] Existing high-speed bearing cages such as figure 1 As shown, its publication number is CN109027009A. The inner and outer diameters of the cage 1 are of uniform wall thickness. Bearings using this type of cage, because the inner and outer diameter surfaces of the cage and the inner and outer rib surfaces of the bearing The gap between t...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a high-speed bearing cage, which can solve defects such as unstable operation of the cage, accumulation on one side of the internal grease, and uneven distribution, and at the same time ensure the stability of the shape of the pocket to the greatest extent. Avoid large deformation
