CouplingThe two measurement adjustment methods commonly used in the process can be divided into different measurement tools:
1) Use a knife-shaped ruler and feeler gauge to measure the misalignment of the coupling and use a wedge-shaped clearance rail or feeler gauge to measure the non-parallelism of the end surface of the coupling. This method is suitable for elastic couplings with low speed and low precision requirements. equipment.
2) Use a dial indicator and a meter frame or a special aligning tool to measure the misalignment and non-parallelism of the two couplings. This method is suitable for rotating equipment with high speed, rigid connection and high precision requirements.
It should be noted that: 1. When aligning with feeler gauge and knife-shaped gauge, the surface of the radial end face of the coupling should be flat, smooth, rust-free and burr-free.
2. In order to see the light of the knife-shaped ruler, it is best to use a flashlight.
3. For the final measured value, the anchor bolts of the motor should be completely tightened without any looseness.
4. When aligning with a special tool, make the same mark. In order to avoid the increase of the measurement data error, the backrest wheel should be divided into 4-8 points in order to obtain accurate data.
5. Keeping good records is an important part of correcting.
