Under what circumstances do I need to use a coupling? How to choose and install it?
There are many optional types of couplings used in the reducer, but it is best not to use rigid fixed couplings, which are difficult to install. 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, After screwing on the oil level plug and confirming that it is correct, the test run can be started.
The fixation of the reducer is very important to ensure stability and firmness. Generally speaking, we should install the gear reducer on a horizontal foundation or base, while the oil in the oil drain tank should be able to drain, and the cooling air circulation should be smooth. If the speed reducer is not well fixed and the foundation is unreliable, it will cause and vibrate. It will also cause unnecessary damage to the bearings and gears. The installation position of the reducer should ensure the operation of the staff, including the convenient access to the cursor, vent plug and oil drain plug. After the installation of the gear reducer is completed, the inspector should comprehensively check the accuracy of the installation position in order to determine the reliability of each fastener.
When the reducer is installed, pay special attention to the centering of the transmission center axis, otherwise it will cause damage to the gear reducer. Once installed improperly, the load will increase, which will easily cause damage to the bearing and even break the output shaft. 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 or sprocket transmission, etc.
If the output bearing is subjected to a large radial load, a reinforced type should also be selected. When installing the transmission parts on the output shaft of the gear reducer, you must pay attention to the soft operation. It is forbidden to use hammers and other tools to install it roughly. It is best to use the assembly fixture and the internal thread of the end shaft to install, and the drive should be screwed in with the force of the bolt. The parts are pressed into the reducer to protect the internal parts of the reducer from damage.
