Abstract：
 A clutch with adjustable friction index comprises a driving shaft and a slave shaft, whereon the flange of the driving shaft fixed a metal plate, whereon the flange of the slave shaft fixed a chinaware blade and an assistant electrode, a stainless steel sleeve filled in with water base lubricant, and the seal gasket between the driving shaft and the sleeve and between the slave shaft and the sleeve. The metal plate and the chinaware blade consists a friction couple, the friction index can be on-line adjusted through a voltage forced on the metal plate and the assistant electrode. This clutch doesn't need an outside pressure enforcing device and can avoid over friction raised by enforced outside pressure.
