Gear is used to transfer the prime mover and power movement, movement in the form of its transformation to meet the needs of the work of the device is an important part of the machine. The reasonableness of transmission will have a direct impact on the work of the machine performance, weight and cost. In addition to drive a reasonable program to meet the work function of the device, also called for a simple structure, convenience, low cost, high transmission efficiency and facilitate the use of maintenance. Design of the Central Plains motive for the electric motors, machine work for the conveyor belt. Transmission program uses twostage drive, the firstclass drive for the belt drive, the secondclass drive for the singlestage spur gear reducer. With a lower transmission capacity. In the same torque transmission, the size of the structure than the other forms, but there is the advantage of overload protection, but also ease the shock and vibration, the layout of the highspeed transmission level in order to reduce the transmission of torque, Reduce the size of the structure of the transmission belt. Gear transmission efficiency, and suitable for a wide range of power and speed, longer life, is the most widely used in modern machines of bodies . This reducer mainly applied to transport machinery, but also can be used for metallurgy, mining, petroleum, chemical and other general machinery. From the above data we can see a pact gear reducer, transmission, high efficiency, smooth operation, transmission ratio, small size, convenient processing, long life and so on. This design uses a singlestage spur gear transmission (note the advantages and disadvantages of spur gear transmission).
