Couplings suitable for reducers, commonly used couplings on reducers



As we all know, the reducer is a very common power transmission mechanism, which is used in various mechanical transmission systems. The importance of the coupling in the reducer is very high. The installation and use of the coupling is directly related to the operation effect of the reducer, and it must comply with the technical specifications and standards.

Reasonable installation and use of the coupling in the reducer, pay attention to the following points. There are many optional types of couplings used in the reducer, but it is best not to use rigid fixed couplings. This type of coupling is difficult to install. Once improperly installed, it will increase the load, which is easy to cause The damage of the bearing can even cause the break of the output shaft. The fixation of the reducer is very important to ensure stability and firmness. Generally speaking, we should install the reducer on a horizontal foundation or base, while the oil in the oil drain groove should be able to drain, and the cooling air circulation should be smooth. If the speed reducer is not fixed well and the foundation is unreliable, it will cause and vibrate. It will also cause unnecessary damage to the bearings and gears. The transmission coupling of the reducer should be equipped with protective devices when necessary, such as protrusions on the coupling or the use of gears, sprocket transmission, etc. If the output bearing is subjected to a large radial load, a reinforced type should also be selected. The installation position of the reducer should ensure the operation of the staff, including the position where the cursor, the vent plug and the oil drain plug can be easily accessed. After the installation of the reducer is completed, the inspector should comprehensively check the accuracy of the installation position in order to determine the reliability of each fastener. Before the reducer is running, prepare for operation. Remove the vent plug of the oil sump and replace it with a vent plug, open the oil level plug screw to check the oil line height, add lubricating oil beyond the oil level plug screw to overflow, Then screw on the oil level plug and confirm that it is correct, you can start trial operation. The trial operation time of the reducer cannot be less than two hours. The standard for normal operation is smooth operation, no vibration, no noise, no leakage, and no impact. If abnormal conditions occur, they should be eliminated in time.
