Gear Reducer Drive

The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the original moving part (motors)and the working machine(grinding mill). It plays a role in matching the speed and transmitting torque between the prime mover and the working machine or the actuator, and is extremely widely used in modern machinery.

Gear reducer transmission efficiency is the highest in common mechanical transmission, which has great economic significance for high-power transmission.Transmission ratio is stable and accurate.

Belt Drive

The belt drive uses a tensioned (annular) belt, which is set on the pulleys of two drive shafts. It relies on the friction force generated when the belt and the pulley are tensioned to transmit the power of one shaft to the other shaft. The belt rotation can be used for large-distance transmission between two shafts (working machine and power machine). Due to the elasticity of the belt, it can alleviate the impact and reduce the vibration, and the transmission is stable, but it cannot maintain a strict transmission ratio (the ratio of the number of revolutions per minute of the driving wheel to the number of revolutions per minute of the driven wheel). When the transmission part encounters obstacles or overload, the belt will slip on the pulley, so it can prevent the damage of the mechanical part. The belt drive is simple, easy to operate, low cost, easy to maintain, and easy to disassemble and replace. However, because the belt slips on the pulley, the mechanical efficiency of the belt drive is low, and the durability of the belt itself is also poor, and it will gradually extend after a long time, so it should be adjusted at any time.
