Permanent magnet crane round suction cup

Abstract

The utility model relates to permanent -magnetic chuck technical field, and disclose a kind of permanent -magnetic crane circular chuck, including shell, the lower surface of shell is equipped with permanent -magnetic chuck, threaded hole is set in both ends of connecting seat, the one end of connecting plate is equipped with mounting hole, first connecting shaft is set in the inside of mounting hole.The utility model is injected lubricating oil into recess by oil inlet hole, and lubricating oil is stored by oil storage sponge adsorption, when connecting plate rotates around first connecting shaft axis, ball is rotated by the driving of mounting hole inner wall friction force, in this process, the lubricating oil adsorbed on the surface of ball is evenly applied to mounting hole inner wall, to form sustained lubrication to the hinged place of first connecting shaft and connecting plate, reduce the friction resistance between first connecting shaft and connecting plate, by reducing friction resistance, further inhibit wear, maintain the original design cooperation clearance of first connecting shaft and mounting hole, ensure force transmission stability.
