Abstract

The invention discloses a conical dynamic pressure spiral groove bearing containing self-lubricating material, aiming at solving the problem of adhesive wear of a conical dynamic pressure spiral groove bearing at present. According to the invention, the lubrication condition of the conical dynamic pressure spiral groove bearing is improved at the low-speed and heavy-load working conditions, and the bearing performance of the conical dynamic pressure spiral groove bearing is further improved. The surface, which is in contact with a bearing main shaft (1), of a self-lubrication bearing seat (2) is provided with a conical concave pit, and the surface, which is in contact with the self-lubrication bearing seat (2), of the bearing main shaft (1) is provided with a conical body meshed with the self-lubrication bearing seat (2); the surface of the conical body of the bearing main shaft (1) is provided with a spiral groove (11); the self-lubrication material is adopted by the self-lubrication bearing seat (2), or a self-lubrication material coating (21) is prepared on the conical contact surface of the bearing seat.

Description

technical field [0001] The invention relates to a novel self-lubricating material tapered dynamic pressure spiral groove bearing, which belongs to the field of mechanical engineering. Background technique [0002] Conical hydrodynamic spiral groove bearings are widely used in rotating machinery (centrifuges, flywheel energy storage, motors, pump machinery) because of their compact structure, large load capacity, and low power consumption. The basic principle of this type of bearing is to use the pumping effect and the step effect generated by the spiral groove during rotation to form a hydrodynamic oil film, so that it has load-carrying capacity. Under a given load, the traditional conical dynamic pressure spiral groove bearing must reach the corresponding speed to form a dynamic pressure oil film, and before this speed, because the dynamic pressure oil film is not formed, the bearing has high friction and is easy to wear. This defect of tapered bearings is mainly determine...
