Description

A kind of joint ball bearing

Technical field

The utility model belongs to technical field of bearings, is specifically related to a kind of joint ball bearing.

Background technology

The structure of oscillating bearing is simpler than rolling bearing, and it is mainly by an inner ring that has a spherical outside surface and oneOuter ring by Internal Spherical Surface forms. Oscillating bearing is generally used for the oscillating motion that speed is lower, due to slidingsurfaceFor spheric, also can within the scope of certain angle, make banking motion, in bolster and axle housing hole nonconcentricityWhen large, still can normally work. Oscillating bearing can bear larger load. According to its different types and structure,Can bear radial load, axial load or radially, axial simultaneous joint load. Due at inner ringSpherical outside surface on stud with composite, therefore this bearing can produce self-lubricating at work. Be generally used for speedLow oscillating motion, and low speed rotation also can be made banking motion within the scope of certain angle, when bolster withWhen axle housing hole nonconcentricity is larger, still can normally work. Self-lubricating knuckle bearing is applied to water conservancy, professional machineThe industries such as tool. Oscillating bearing is widely used in engineering hydraulic jack, forging machine tool, and engineering machinery, automation is establishedStandby, automobile absorber, the industries such as water conservancy machinery. But traditional joint ball bearing does not have good anti-friction wear-resistantPerformance, service life is low, and this time utility model utilizes bionical tribology principle to improve traditional joint ball journalHold.
