Abstract: Aiming at the transmitting requirements of high power supply and hydraulic oil in the limited rotation range, the design of new wind equipment of the cable and oil pipe is discussed. In this paper, the wind equipment of the cable and oil pipe including its composition, operation principle and structural feature is introduced. The design method of the wind equipment of the cable and oil pipe is described in detail. The structures inlayed in radius and composed in axle, the fixed plate and motive plate with different diameters are illustrated. The wind equipment is characterized by compact structure, low cost, combination function, wide application scope, safe and reliable performance. It can achieve transmitting of the power supply, signal and hydraulic oil in limited room with the simplest and the most reliable method and can resolve simultaneously the winding problem of several cables, optical fiber cables and oil pipes.
