Abstract

The invention discloses an overrunning clutch which comprises a base, a bearing, a transmission shaft, a limiting ring, fixed shafts, rotary shafts, magnetic-steel fixed blocks and non-magnetic-conducting metal discs. The non-magnetic-conducting metal discs are fixed at the upper end of the transmission shaft, the limiting ring is fixed at the outer edge of the upper end of the base, each fixed shaft is fixed at the upper end of the base along the inner side of the limiting ring, each rotary shaft is fixed on one fixed shaft in a pivoted manner, a pair of the magnetic-steel fixed blocks are fixed on each rotary shaft, a pair of permanent magnets opposite in polarity are fixed at second ends of each pair of the magnetic-steel fixed blocks, and the non-magnetic-conducting metal discs are disposed among the rotary shafts. By utilizing the Lenz's law, force is transmitted onto the base from the transmission shaft, and contactless overrun clutching is realized. The permanent magnets do not contact with the non-magnetic-conducting metal discs, so that friction is not caused, impact force is extremely small, abrasion cannot be caused, and the service life of the clutch is greatly prolonged.

Description

technical field [0001] The invention relates to a clutch, in particular to an overrunning clutch. Background technique [0002] The overrunning clutch is one of the basic parts of mechanical transmission. It is an important part used for power transmission and separation between the prime mover and the working machine or between the driving shaft and the driven shaft inside the machine. It uses the speed change or A device that changes the direction of rotation and realizes the automatic clutch function. Common overrunning clutches include pawl overrunning clutches, roller overrunning clutches and sprag overrunning clutches. [0003] The pawl type overrunning clutch is to realize the transmission or overrunning of force by using the mutual fitting or separation of parts in the structure, and there is impact and noise when combined; [0004] Roller type overrunning clutch is composed of inner ring, roller, outer ring, spring and ejector pin, etc. Generally, the inner ring i...
