Planetary gear reducer

The transmission ratio of a planetary gear reducer refers to the ratio of the output shaft speed to the input shaft speed, usually represented by the symbol i. The size of the transmission ratio i determines the relationship between the output shaft speed and the input shaft speed of the gearbox, that is, the output speed is equal to the input speed divided by the transmission ratio.
It is one of the important indicators for measuring the performance of a gearbox. The transmission ratio of a planetary gear reducer refers to the ratio of the output shaft speed to the input shaft speed, usually represented by the symbol i. By reducing the speed of the output shaft to increase the output torque, the purpose of deceleration can be achieved. The larger the transmission ratio, the lower the output shaft speed and the greater the output torque. The calculation method for transmission ratio is to divide the output shaft speed by the input shaft speed.
Normally, the transmission ratio of planetary gear reducers can be achieved by selecting the appropriate gear combination. Different types of reducers have different transmission ratio ranges, and suitable reducer models can be selected according to actual needs. In engineering applications, the selection of transmission ratio for reducers should take into account factors such as load characteristics, working environment, and required output torque.
The transmission ratio of planetary gear reducers is determined according to actual needs, and different application scenarios require different transmission ratios. Usually, the larger the transmission ratio, the lower the output shaft speed and the greater the output torque.
