<p>PURPOSE:To certainly prevent the hanging load from falling when the positive clutch which can constantly convey torque by the pressing force of the spring is used for the winding device. CONSTITUTION:The disk rotor 1 which is joined by the key with the driving shaft 2 and the rotor which is joined with the driven shaft 4 are clutch-operated by the pressing device 7 supported by the rotor 3. Both shafts 2, 4 are usually coupled by frictionally clamping a pair of the linings 12 with the disk rotor 1 through the piston 9 by the spring 8 fitted in the cylinder 10. Then, when the oil hydraulic pressure is injected into the piston cylinder from the oil drain hole 5 throhg the hose 6, the frictional clamping of the lining 12 and the disk rotor 1 are disconnected. Therefore, the positive clutch with the spring can be obtained and the falling of the hanging load can be prevented.</p> |
