Enough solve the above technical problem.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of ratchet device of rotary-wing transmission, including ratchet and ratchet mandrel, the ratchet inside circumference are evenly distributed with
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, close to each protrusion at two bearings seat in the middle part of the ratchet mandrel
There is an annular convex platform, protrusion has a partition in the middle part of the ratchet mandrel, and the two annular convex platform spaced winding ratchet mandrel axis is uniformly distributed
Have several pawl pin shafts across partition, the detent pin number of axle is equal with ratchet quantity, the pawl pin shaft it is upper in every
Plate two sides are respectively hinged with a pawl, the ratchet and ratchet mandrel and are sequentially connected 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 and pawl are connected 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.
The utility model has the beneficial effects that a kind of ratchet device of rotary-wing transmission provided by the utility model, is realized first
The single-direction transmission of ratchet and inner spindle and the function of reversely surmounting；Secondly, the engagement of multipair pawl and ratchet, it can be very big
The bearing capacity of structure is improved in degree；Finally, being uniformly distributed for multipair pawl and ratchet engagement, is effectively reduced shock loading
And noise.
