In the reducer series, the gear reducer is widely used in servo, stepper, DC and other transmission systems because of its small size, high transmission efficiency, wide reduction range and high precision. Their role is to ensure the premise of precision transmission. Down, mainly used to reduce the speed and reduce the load/motor moment of inertia ratio. How to choose a gear reducer? 1. When choosing a gear reducer, please multiply the rated torque of the servo motor you choose by the reduction ratio. The value obtained is in principle less than the rated output torque of a similar reducer provided by the product sample, and also takes into account the drive motor. Actual required overload capacity and maximum working torque. The maximum working torque required is less than 2 times the rated output torque. After meeting the above conditions, please select the smallest reducer. Smaller reducers are relatively low cost. If there is not enough space for the motor reducer to connect in a straight line. You can also choose a corner reducer that can turn the torque 90 degrees. 2. Consider the return clearance of the gear reducer. The smaller the return gap, the higher the accuracy and the higher the cost. Users should choose to meet the accuracy requirements of the reducer. 3. Also consider lateral/radial force and average life. Reducers with large lateral/radial forces are very reliable in installation and use and are not prone to problems. Usually its average life far exceeds the life of the servo motor. After meeting the above indicators, you can choose the gearbox suitable for your motor on the installation size, shaft diameter and input flange according to the product catalog provided by the company. Finally, you must also consider the weight of the motor. One type of reducer is only allowed to match motors of less than a certain weight. The motor is too heavy. Long-term operation will damage the input flange of the reducer.
