The invention relates to a deep groove ball bearing with a pulley groove on the outer diameter of an outer ring of the deep groove ball bearing, which comprises the outer ring, an inner ring, a retainer cover, a retainer seat, a steel ball and rivets. The outer diameter of the outer ring is provided with the crescent pulley groove which only needs finish turning instead of grinding, so that cost is reduced, friction force is increased when the deep groove ball bearing is used, and the problem of relative sliding of the bearing is solved. The invention particularly relates to a pulley bearing, which is suitable for pulleys and has the advantages of convenience in mounting and flexibility in use.
Description
technical field [0001] The invention relates to a bearing. Background technique [0002] Currently used in the construction industry and small household application accessories, simple pulley blocks are used, but these pulleys do not use special pulley bearings, which brings inconvenience to use. Contents of the invention [0003] In view of the above disadvantages, the present invention proposes a deep groove ball bearing with a pulley groove on the outer diameter of the outer ring, which solves the problem of ease of use and also solves the problem of safety in use. [0004] The invention constructs a deep groove ball bearing with a pulley groove on the outer diameter of the outer ring, which is composed of an outer ring, an inner ring, a cage cover, a cage seat, steel balls and rivets. A crescent-shaped pulley groove is provided in the middle of the outer cylindrical surface of the outer ring. [0005] The invention has the advantages of reducing labor costs, reducing...
