Abstract:
A silicone grease composition is disclosed. The grease composition contains a silicone oil and zinc dialkyldithiocarbamate as an extreme-pressure additive. The grease composition contains substantially no zinc dialkyldithiophosphate. The grease composition achieves high friction characteristics and wear characteristics. A method for transmitting torque of a clutch or a torque limiter mechanism is also disclosed. Moreover, a method for producing a clutch or a torque limiter mechanism is disclosed. The methods utilize the aforementioned grease composition.
