Harmonic reducer manufacturer-how does the motor match the harmonic reducer

2023-09-11

Harmonic reducer is generally composed of three parts: gear, rack and transmission shell; while planetary reducer is generally composed of two parts, shell and internal gear, harmonic reducer has high transmission efficiency, low noise and light weight; planetary reducer The transmission efficiency is low, the noise is high, and the weight is heavy. From the structural point of view, the harmonic reducer is composed of one or more discs and cranks. Its working principle is, when the input speed is greater than the output speed, the disc will continue to run due to inertia. The harmonic reducer manufacturer tells you that at this time, the crank will transmit kinetic energy to the disc through the gear and change its direction of movement. Due to the different tooth profiles of the gears, the purpose of deceleration can be achieved in this way. How does the motor match the harmonic reducer? Today, the manufacturer of harmonic reducer will give you a detailed explanation of how the motor matches the harmonic reducer. Let's have a look.

First of all, the power of the motor and the harmonic reducer must be matched. We can see the power of the motor through the manufacturer's brand. We must first determine the parameters (torque and speed) of the harmonic reducer, and then match the appropriate motor according to the parameters of the harmonic reducer. First, calculate the output power according to the torque value of the output shaft and the speed of the output shaft, and then multiply this value by 1.2, this is called power margin. Ask the staff who sell the reducer directly how much motor their reducer should be equipped with. The manufacturer of the harmonic reducer said that this is a standardized configuration. The engineers of the manufacturer are more professional. When the harmonic reducer is connected with the motor, it is directly suit on the main shaft of the working machine. When the reducer is running, the counter torque acting on the box body, the anti-torque bracket installed on the box body is balanced by other methods, directly matched, and the other end is connected with the fixed bracket.

If the power of the harmonic reducer is different from the power of the motor, the output torque of the motor is at least 2 times the rated torque when overloaded, and the harmonic reducer is easy to be damaged, so unless there are reliable protection measures or ensure that overload conditions are never possible, the motor can be matched with the harmonic reducer to make it operate better and improve the working efficiency. When matching the motor to the harmonic reducer, the correct method must be followed, or directly find manufacturers or sales personnel to match, harmonic reducer manufacturers said, it is easier to make correct judgments, so as to avoid detours, harmonic reducer is a kind of gear transmission enclosed in a rigid shell, Worm drive, gear-worm drive composed of independent components, commonly used as a reduction transmission device between the original moving part and the working machine, it plays the role of matching speed and transmitting torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery.
