Description
Technical field
The present invention relates to a kind of clutches, more particularly to a kind of torsion spring type freewheel clutch.
Background technology
Freewheel clutch is the important component for realizing power between driving shaft and driven shaft and transmitting and detaching.It is to utilize
The velocity variations of driving and driven part or the transformation of direction of rotation have the device of voluntarily clutch function.Existing freewheel clutch
Including the case and ontology being connected, the end face of case is located at the ontology side, and ontology is annular, is set on the internal perisporium of ontology
Be equipped with the groove for placing roller and compression spring, groove has multiple and is uniformly distributed, due to existing reeded bottom wall, antetheca and
Rear wall is to be process on the body, and shape is complex so that the broaching tool structure of broaching body upper groove is also more multiple
Miscellaneous, wire pulling method surplus is big, and processing efficiency is low and broaching tool is of high cost, and because the reason of groove antetheca and rear wall makes ontology consume
Take that material is more, these all make the production cost of existing freewheel clutch higher.Moreover, because ontology inner circumferential space is limited,
The axis of compression spring is longer, and the axis of compression spring is perpendicular to roller, if being intended to by increasing roller quantity come the carrying of lifting clutch
Ability, roller quantity are limited.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of torsion spring type freewheel clutch, ontology internal perisporium shape
