The offset detection and adjustment of motor and coupling is an important step to ensure the stable operation of mechanical equipment。The following is a detailed detection adjustment method：

one、Offset detection method

1. Traditional method：

• Tool measurement：The different concentricity of the coupling can be measured using a knife rule and a piston rule，The non-parallelism of the end face of the coupling is measured by wedge gap rail or feeler ruler。This method is suitable for low speed elastic joints、Equipment with low precision requirements。But be warned，This approach may be limited by the field environment and equipment complexity。

• Wire winding method：Wrap two pieces of wire around the two couplings，Adjust the distance between the wires，And rotate the axis all the way around，Observe the state of the wire to determine the deviation。This method is also suitable for low speed、Equipment with low precision requirements，But the operation is more complicated，With limited accuracy。

2. Advanced method：

• Laser alignment instrument：Using precision laser alignment instrument（Like SwedenEasy-laserseries）Conduct testing。The method is based on double laser and double meter method，Install the laser detectors on the rotating shafts on both sides of the coupling，In order to9-12-3O clock measurement reading value，The alignment of the axis can be checked immediately，And dynamically monitor the adjustment process。This method has high precision、Advantages of high efficiency，Suitable for high speed、High precision required equipment。

two、Adjustment method

1. Adjusting gasket：

• When installing the device，The slave motor is usually installed first（Like a pump），Make its axis horizontal，Then install the driver（Electric machine）。timing，Mainly by adjusting the drive（Electric machine）The support under the foot of the shims to achieve。If the motor is higher than the fixed end，Gaskets should be reduced；If the motor is lower than the fixed end，Gaskets should be added。

2. Precise adjustment：

• Based on the offset detection results，Calculate the exact thickness or amount of gasket adjustment that needs to be made。For angular displacement and radial displacement，Calculations and adjustments need to be made separately。

3. Review and confirmation：

• After adjustment，Measurements should be retaken，Verify that the offset has been adjusted to the allowable range。If necessary，It can be adjusted several times until the requirements are met。

three、Matters needing attention

1. Safe operation：During offset detection and adjustment，Be sure to follow safe operating procedures，Prevent accidents。

2. Equipment shutdown：Testing and adjustment work should be carried out in the equipment shutdown state，To ensure the accuracy of measurement and the safety of adjustment。

3. Professional tool：Use professional tools for inspection and adjustment whenever possible，To improve work efficiency and measurement accuracy。

4. Experience accumulation：For complex equipment and high precision requirements，Experienced technicians are required to operate and judge。

To sum up，The offset detection and adjustment of motor and coupling is a careful and important work link。Through reasonable detection methods and scientific adjustment means，It can ensure the stable operation of mechanical equipment and extend the service life of equipment。
