Working principle of ZQH750-23.34-III cylindrical gear reducer

The working principle of the ZQH750-23.34-III cylindrical gear reducer is to use the meshing transmission of gears. By meshing the small gear with fewer teeth on the input shaft with the large gear with more teeth on the output shaft, the purpose of reducing speed and increasing torque is achieved. Specifically, as follows:

Deceleration principle: The motor and other power sources drive the input shaft of the reducer to rotate, and the small gear on the input shaft rotates accordingly. The small gear meshes with the large gear on the intermediate shaft, driving the intermediate shaft to rotate. Due to the fact that the large gear has more teeth than the small gear, the intermediate shaft speed is lower than the input shaft speed based on the inverse relationship between the gear ratio and the speed ratio. If it is a multi-stage reduction, the intermediate shaft drives the large gear on the output shaft to rotate through its small gear, further reducing the speed, and ultimately outputting lower speed power from the output shaft to achieve the reduction function.

Principle of torque increase: According to the law of conservation of energy, the input and output power of the gearbox remain basically unchanged (ignoring energy loss), and power is equal to the product of torque and speed (P=T × n, where P is power, T is torque, and n is speed). Due to the decrease in output speed, the output torque will correspondingly increase, and the proportion of torque increase is the same as the proportion of speed decrease, which is proportional to the reduction ratio, thus providing greater driving torque for the load.
