Technical Field

[0002] A coupling, also known as a coupling, is a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque; sometimes it is also used to connect the shaft with other parts (such as gears, pulleys, etc.). It is usually composed of two halves, which are connected by keys or tight fits, fastened to the two ends of the shaft, and then connected in some way.

When the length of the coupling needs to be increased, the driven shaft 6 moves, driving the spring 33 to stretch, so that the distance between the driven shaft 6 and the driving shaft 7 increases. When the length of the coupling needs to be reduced, the driven shaft 6 moves, driving the spring 33 to contract, so that the distance between the driven shaft 6 and the driving shaft 7 decreases. The sliding block 322 can only move inside the sliding groove 312, ensuring that the linkage shaft 32 will not separate from the linkage cylinder 31.
