AbstractReducer is an enclosed by a rigid casing of gear transmission, worm transmission or gear - worm transmission, which is composed of independent components used in the study and work as a deceleration machine, between the transmission device, In a few cases are used to speed transmission device, this is called the growth. Due to the structure is compact, gear reducer, high efficiency and reliable motion using simple maintenance and batch production in the modern machines, so it is widely used in the measures.I designed by slow-moving hoist device is termed as main body, and motor and roller, to realize the provisions of the object function. Speed drive Reliable in performance, simple in structure, compact, easy to manufacture.The main design ideas from the working principle of thrust machine, then according to the corresponding functional components design, organization, and the optimal portfolio selection. Comprehensive utilization of the motor and reducer, ball screw, pusher and to realize the coordinated movement, the default function to thrust machine. All components design through scientific data processing and using Auto Cad software powerful drawing function and Word of editing functions, which makes the design scheme illustrated, lifelike.Keywords reducer gear axis motor
