How to install copper worm gear reducer correctly
In the copper worm gear reducer, the reducer is widely used in servo, stepping, DC and other transmission systems because of its small size, high transmission efficiency, wide range of deceleration, high precision and many other advantages. It is mainly used to reduce the rotational speed, increase torque and reduce the load/motor inertia ratio on the premise of ensuring the precision transmission. In the planet > reducer industry, Germany NEUGART is undoubtedly the world's most famous manufacturer, but also the largest domestic sales manufacturers. The company has the world's top mechanical engineers and excellent equipment, product sales in more than 100 countries and regions. In the past few years, some users in the use of reducers, due to illegal installation and other human factors, resulting in the output shaft of the reducer broken, so that enterprises suffered unnecessary losses. Therefore, in order to better help the majority of users to use the planetary reducer, this paper analyzes the reasons for the shaft breakage of the reducer and the drive motor, and introduces in detail how to install the planetary reducer correctly.
Broken shaft problem with different concentricity
Some users broke off the output shaft of the motor after running for several months. Why does the reducer twist the output shaft of the drive motor? For this reason, we looked at the output shaft cross-section of the drive motor and found that the output shaft cross-section of the reducer is almost exactly the same. The outer ring of the cross section is brighter, and the darker the cross section is toward the axis, the more broken it is at the axis. Figure 2 is a photograph of the cross section. This fully explains that the main reason for the output shaft of the drive motor to be broken is that the motor and the decelerator are not aligned when they are assembled.
When the concentricity between the motor and the decelerator is guaranteed to be very good, the motor output bearing is only subjected to rotational force, running smoothly. However, the output shaft bears the radial force from the input of the reducer when it is not centered. The long-term effect of the radial force will force the output shaft of the motor to bend, and the direction of bending will change with the rotation of the output shaft. When the output shaft rotates one week, the direction of lateral force changes 360 degrees. If the concentricity error is large, the radial force will cause the temperature of the motor output shaft to rise, and the metal structure will be destroyed continuously. Finally, the radial force will exceed the radial force that the motor output shaft can bear, and eventually lead to the output shaft of the drive motor broken. When the concentricity error is greater, the driving motor output shaft breaking time is shorter. When the output shaft of the drive motor is broken, the input side of the reducer will also bear the radial force from the motor. If the radial force exceeds the maximum radial load both of them can bear at the same time, the result will lead to deformation and even fracture of the input side of the reducer. Therefore, it is very important to ensure concentricity during assembly.
