How to choose a planetary gear reducer, what are the key points of selection

Planetary gear reducers are also called planetary reducers and servo reducers.In the reduction family, planetary reducers are widely used in servo motors, pedal motors, DC motors and other drive systems because of their small size, high transmission efficiency, large reduction range and high precision.Today, I will show you how Li Aijie chooses 'planetary gear reducer' and what are the key points of the selection.

The planetary gear reducer is the most important type to match the servo motor.When selecting a planetary gear reducer, first determine the reduction ratio of the reducer.If the standard reducer does not have the desired reduction ratio, choose an off or custom reducer.

Secondly, after determining the reduction ratio, please multiply the rated torque of the servo motor you choose by the reduction ratio, and the obtained value should be less than the rated output torque of similar reducers provided in the product catalog in principle.At the same time, the overload capacity of the driving motor and the maximum working torque required in practice should also be tested.The required maximum operating torque should be noted in second place of the rated output torque.After meeting the above conditions, please choose the smallest volume reducer.The cost of a smaller reducer is relatively low.

Also, consider the backlash of the planetary range gears.The smaller the return gap, the higher the accuracy and the higher the cost.Users can choose from a range of reducers that meet their accuracy requirements.Outboard/radial forces and average life should also be considered.A reducer with a large side/radial force has high reliability in installation and use, and is not easy to cause problems.In general, the average life of a servo motor is longer than the average life of a servo motor.Feel free to continue browsing Restore Maker to learn more about Restorers.
