Ge Le Transmission
Glee Transmission Technology Co., Ltd. is a research and development, production and sales in one of the power transmission manufacturing enterprises, the company is located in Wenling City Daxi town Jin Ao industrial area, convenient traffic.
The company produces reducer products complete, the main products are: precision planetary gear reducer, NMRV series of aluminum alloy worm gear reducer, UDL series CVT, SRC series helical gear reducer, SKM helical-quasi-hypoid gear (K, R, F, S) series of hard gear reducer, PC helical gear reducer and so on. Products are widely used in the automation industry, industrial robots, aerospace, CNC machine tools, metallurgical mines, beer drinks, tobacco light industry, environmental protection engineering, warehousing logistics, plastic machinery, lifting transport, three-dimensional parking, automobile manufacturing, textile, food, ceramics And so on.
In the family of worm gear reducer, the planetary reducer is widely used in the transmission system such as servo, stepping and DC with its small size, high transmission efficiency, wide speed range and high precision. Its role is to ensure that the premise of precision transmission, mainly used to reduce the speed increase torque and reduce the load / motor moment of inertia ratio. In the planets> reducer industry, Germany NEUGART company is undoubtedly the world's most famous manufacturers, but also the largest domestic sales of the manufacturers. The company has the world's top mechanical engineers and excellent equipment, product marketing around the world more than 100 countries and regions. In the past few years, some users in the use of reducer, due to illegal installation and other human factors, which led to 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 for the reducer and drive motor broken shaft of the reasons for the analysis, and a detailed description of how to correctly install the planetary reducer.
Do not have the heart of the broken axis problem
Some users are driving the motor's output shaft after a few months of operation. Why does the reducer break the output shaft of the drive motor? For this reason, we looked at the cross section of the output shaft of the drive motor and found that the cross section of the output shaft of the gear unit was almost exactly the same. Cross-section of the outer ring is brighter, and the more the color toward the axis of the darker, and finally to the axis of the broken! Figure 2 is a cross-sectional photograph. This fully illustrates the cause of the drive motor output shaft shaft is the main reason is the motor and reducer assembly do not mind!
When the motor and reducer assembly when the concentricity of the guarantee is very good, the motor output bearing only by the rotating force, running will be very smooth. However, when the center is not concentric, the output shaft is subjected to a radial force from the input of the gear unit. This long-term radial force will cause the motor output shaft to be forced to bend and the direction of the bend changes as the output shaft rotates. Each direction of rotation of the output shaft, the direction of the lateral force changes 360 degrees. If the concentricity error is large, the radial force causes the motor output shaft temperature to rise, its metal structure is constantly destroyed, and finally the radial force will exceed the motor output shaft can bear the radial force, and finally lead to drive The motor output shaft is broken. When the greater the error of the concentricity, the shorter the time the drive motor output shaft is broken. While the drive motor output shaft is broken, the reducer input also receives radial forces from the motor. If the radial force exceeds the maximum radial load that the two can bear, the result is Resulting in deformation of the reducer input or even fracture. Therefore, it is important to ensure concentricity when assembling!
