Installation Sequence and Precautions for Gear Motors

Proper installation, use, and maintenance of gear motors are crucial for ensuring the normal operation of mechanical equipment.

Therefore, when installing a planetary gear motor, please strictly follow the installation sequence below.

1. Before installation, confirm that the motor and gear motor are intact and carefully check that the dimensions of all parts connecting the drive motor and gear motor match. This refers to the dimensions and tolerances between the locating boss and shaft diameter of the drive motor flange and the locating groove and hole diameter of the gear motor flange; wipe away dirt and burrs from the mating surfaces.

2. Unscrew the plug on the process hole on the side of the gear motor flange. Rotate the input end of the gear motor to align the locking hexagonal head cap with the process hole. Insert an Allen wrench to loosen the locking hexagonal head screw.

3. Hold the drive motor and align the keyway on its shaft perpendicular to the locking screw in the input hole of the gear motor. Insert the drive motor shaft into the input hole of the gear motor. During insertion, ensure that both are concentric and that the two flanges are parallel. If the concentricity is not uniform or the flanges on both sides are not parallel, the cause must be investigated. Furthermore, during installation, hammering is strictly prohibited. This is to prevent excessive axial or radial force from damaging the bearings and to allow for a manual assessment of the fit. The method to determine the concentricity and parallelism of the flanges is: after inserting the flanges together, they should be roughly touching, with consistent gaps.

4. To ensure even force distribution on the flange connection, first loosely screw on the drive motor, but do not tighten it completely; then gradually tighten the four screws diagonally; finally, tighten the clamping screw at the input end of the geared motor. Always tighten the drive motor screws first, then tighten the clamping screw at the input end of the geared motor.

Note: The correct installation of the geared motor and the mechanical equipment is similar to the installation of the geared motor and the drive motor. The key is to ensure the concentricity of the geared motor output shaft and the input shaft of the driven part.
