Several ratchets, the ratchet both ends are respectively provided with an end cap, and the two end cap is extended with bearing block, the ratchet mandrel into ratchet
It is rotatablely connected by the bearing and two end cap that are set on bearing block, each protrusion at close two bearings seat in the middle part of the ratchet mandrel
There is an annular convex platform, the ratchet mandrel is central raised to have a partition board, the two annular convex platform spaced winding ratchet mandrel axis uniformly distributed
Have several pawl axis pins across partition board, the detent pin number of axle is equal with ratchet quantity, the pawl axis pin it is upper in every
Plate both sides are respectively hinged with a pawl, and the ratchet is sequentially connected with ratchet mandrel by pawl and ratchet engagement, the detent pin
Torsionspring, described torsionspring one end and ratchet mandrel are equipped on axis between pawl and the annular convex platform closed on the pawl
Connection, the torsionspring other end are connect with pawl close to ratchet mandrel one side.
Further, involute spline is distributed in the ratchet mandrel inside circumference.
Further, the quantity of the ratchet is six.
Further, be evenly equipped with can be with the circle-arc tooth of toothed belt transmission for the ratchet outer circumference.
Beneficial effects of the present invention：A kind of ratchet device of rotary-wing transmission provided by the invention, realize first ratchet with
The single-direction transmission of inner spindle and the function of reversely surmounting；Secondly, the engagement of multipair pawl and ratchet can be carried largely
The bearing capacity of high structure；Finally, multipair pawl and ratchet engagement are uniformly distributed, and are effectively reduced shock loading and noise.
