Abstract
Clutch is the automobile transmission and engine directly connected to the assembly，its function is cut off and the achievement of the transmission of power transfer, to ensure that the car will start when the engine and transmission smooth and engagement, to ensure a smooth start car. Engine and transmission system will be separated when the shift. Reduce the transmission of the gear shift between the impact of. By the time the largest dynamic load. in working, it can limit transmission of the largest faced by the torque, prevent the transmission of parts because of overload and damage. Reduce the transmission of noise and vibration effectively. The design is about friction on the clutch-drilling. The ordinary drill is a single drill. It will improve its productive efficiency, shorten its processing time if assembled a multiple spindle case on. That so calls a multiple drill. Hereby, the keystone of this design paper is how to design a multiple spindle heads. The design subjects include the selection and distribution of gear wheel, the design of spindle, and the guiding equipment and selection of the multiple spindle heads, etc.
Key words: Power System multiple drill multiple spindle heads friction
