• Function

1.Torque transmission: It is primarily used to connect two shafts, like the driving shaft and the driven shaft, enabling them to rotate together and transmit torque. This allows power to be effectively transferred from one shaft to another, ensuring that different mechanical components can work in coordination. For example, it can connect the engine shaft and other components to make the excavator's various working parts operate properly.

2.Compensating for shaft - axis deviation: In actual operation, due to factors such as processing and installation errors or temperature changes, the two connected shafts are difficult to be completely co - axial, and there may be problems such as eccentricity, angular deviation, or axial movement. The coupling can absorb these axis deviations within a certain range, reducing the equipment's dependence on high - precision installation, and thus reducing debugging and maintenance costs.
