Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and specifically relates to an alignment device for couplings. Background Art

[0002] A coupling, also known as a shaft 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 to other parts. It is often composed of two halves, which are respectively connected by keys or tight fits, fastened at both ends of the shaft, and then connected together in a certain way; the coupling can also compensate for the offset caused by inaccurate manufacturing and installation, deformation during operation, or thermal expansion between the two shafts, as well as relieve shock and absorb vibration.

[0003] The rotation centers of the two shafts connected by the coupling should be strictly concentric. When installing the coupling, it must be accurately aligned and centered. Otherwise, it will cause great stress on the coupling and seriously affect the normal operation of the shaft, bearings, and other parts on the shaft, and even cause the vibration of the entire machine, thus damaging the machine parts.

[0004] During the alignment process of the coupling, a dial indicator needs to be used to measure the coupling at multiple angles. When using the double - dial method, the dial indicator needs to be firmly clamped. Otherwise, inaccurate measurement data will occur due to the unstable clamping of the dial indicator.

[0005] Therefore, the utility model provides an alignment device for couplings. Summary of the Utility Model
