In order to be able to control the speed and not make it too fast, many equipment have been installed with reducers. With it, the speed can almost drop. In this device, the coupling is an important part of it. In order to improve efficiency, everyone needs to do a good job in selecting the coupling. So how to choose a coupling?
1. According to the load transmitted by the reducer, the speed of the shaft, due to manufacturing, installation, load deformation and temperature changes, it is difficult to keep the two shafts strictly aligned after installation and adjustment, and there is a certain degree of directional displacement and Deflection angle. When the radial displacement is large, you can choose a slider coupling, and when the angular displacement is large or the connection of two intersecting shafts, you can choose a universal coupling. When the two shafts produce a large additional relative displacement during the working process, a flexible coupling should be used.
2. The coupling should be selected according to the working speed of the coupling and the amount of centrifugal force caused. For high-speed drive shafts, couplings with high balance accuracy, such as diaphragm couplings, should be used instead of eccentric couplings. Slider coupling. When the coupling is selected for the gearbox with severe impact load or the transmission system that requires the elimination of shaft torsional vibration, high elasticity and good shock absorption and excellent inter-axis offset compensation performance can be selected, suitable for impact occasions Couplings, etc.
3. The appropriate coupling can be selected according to manufacturing, installation, maintenance and cost. Under the premise of satisfying the performance of the reducer, a coupling that is convenient for assembly and disassembly, simple maintenance, and low cost should be selected.
There are many types of couplings, and couplings can effectively protect the safe operation of the reducer, and can reduce its burden and prevent it from bearing excessive loads. Therefore, it is related to the use of safety issues, we must choose a suitable coupling for it.
