Half-clutch device B can relatively rotate.
Preferably, described hub internal bore is the stepped hole that outer end is big, the inner is little, setting pressure in the endoporus of sleeve outer end
Plate, pressing plate is fixed with revolution axial end by screw, and pressing plate top is located at the step of hub internal bore.
Preferably, being provided with copper bush between described half-clutch device A and sleeve outer wall.
Preferably, being provided with adjustable plate outside described half-clutch device B, the outer end top holding out against spring is located on adjustable plate, adjusts
Section plate outer face is provided with stop washer and adjusting nut, and described adjusting nut adopts screw thread even with the sleeve outer end of half-clutch device
Connect.Adjustable plate can pass through adjusting nut adjusting position, thus adjusting the pretightning force holding out against spring.
Preferably, described axially extending bore is uniformly arranged 3-12 on ring week.
This utility model using the clutch mode being located at steel ball top using spring in trapezoidal draw-in groove, according to trapezoidal draw-in groove
Sidewall angles, can intuitively calculate relation, convenient construction and the installation of load and clutch on-off it is ensured that cutting in time when transshipping
Disconnected power.
