Before installation, it is essential to check whether the two shafts of the original motor and the working machine are concentric and whether the shaft surfaces have packaging paper or damage. Also, inspect the inner holes of the two halves of the coupling for debris and for any damage to the edges, and if present, clean the shaft and half-coupling thoroughly and treat the damage with fine files. Then, verify that the inner hole diameter and length of the two half-couplings match the diameter and shaft extension length of the original motor and working machine. Generally, it is better to select a half-coupling length for the original motor and working machine that is 10-30mm shorter than the shaft extension length. Elastic coupling

To facilitate installation, it is recommended to preheat the two half couplings in an insulated box or oil pan at 120-150 degrees, making it easier to fit the inner diameter. After installation, ensure that the shaft end does not protrude beyond the half coupling face, with flush alignment being ideal. Measure the distance between the two half couplings: take the average of readings from 3-4 points along the two inner sides of the flange disk, and add the total measured dimensions of the extension section and both diaphragm groups. The error should be kept within the range of 0-0.4mm.

The Compensator Coupling Collector Equipment, due to the traditional collector equipment being located on the non-load end of the motor shaft, relies solely on the motor's single-end bearing to form an overhanging structure. The unbalanced torque during the motor's start and operation can easily cause radial vibration in the collector equipment, which may lead to uneven brush wear and shortened brush service life in mild cases; in severe cases, poor contact between the collector ring and the brush can cause sparking, burnishing the collector ring surface, and even damaging the collector assembly. In the normal operation of sensor equipment, a rigid coupling is typically selected for the compensator, resulting in significant vibration and poor concentricity (within ±0.2mm). In such cases, it is recommended to use an elastic coupling. Outside this scope, rigid couplings can be used. Secondly, when using torque sensors, they should be installed between the power source and load of two couplings, ensuring a fixed and reliable connection to prevent vibration; otherwise, the surface may not operate normally. Additionally, when using standardized torque gauges, regardless of the installation method, the couplings should bear minimal axial force and bending moments to prevent excessive surface stress, which can directly damage the gauge and render it unusable. When using torque sensors, attention must be paid to the installation issues, as torque sensors are power equipment, especially dynamic torque sensors connected to motors. Careful operation is required for the measurement of high torque forces, and the connections between the load and the coupling, as well as between the coupling and the sensor, and the coupling and the power source, are crucial and should not be overlooked.
