Centrifugal Clutch Pulley

Grenco Engineers offers a Centrifugal Clutch Pulley. This has simple construction and is fit on motor shaft for no-load starting. The centrifugal clutch pulley eliminates the drop of voltage in power supplying circuit at the starting time of electric motors. It consists of a shell, spider and spring controlled four shoes lined with friction material. The spider is mounted on the motor shaft, while the spider holds the shell and shoes. The shell fits on with GM bush or two ball bearings on the spider. At the starting of the motor there will be no motion of the shell, i.e., driven pulley. The shoes will be free on the spider. As the motor speed gradually increases, the centrifugal force of the shoes will start to be engaged with shell.

When the motor will attend its full speed, the shoes engage with shell firmly and full load comes on the motor. The clutch portion is available in standard seven sizes – 4.5/8, 5 ½, 6 ½, 7 ½, 8 ½, 10 ½ and 12 ½, while the V-pulley grooved on the shell is made as per customer’s requirement basis. The centrifugal clutch pulley of any motor safety device, such as fluid coupling and electronics device is of low cost. Fluid coupling requires regular attention and maintenance, whereas centrifugal clutch pulley requires only little attention and maintenance. Grenco centrifugal clutch pulley is used in textile and jute mill machinery such as speed frames, ring frames, carding drums, draw frames, knitting machine, weaving looms and twister machine, sugar mill machinery, conveyors and chemical process machinery.
