Correct Installation of Planetary Reducer

- Jan 05, 2021-

Correct installation and use of planetary reducer is an important part of ensuring the operation of mechanical equipment. Therefore, please strictly follow the guidance during installation. Now Gigager engineer will tell you how to install planetary reducer.

1. Before installation, confirm whether the motor and reducer are intact, and strictly check whether the dimensions of each part connecting the motor and the reducer are matched, especially the dimensions and tolerances of the positioning convex platform of the motor & the input shaft to the groove of the reducer.


2. Unscrew the screw on the dust-proof hole on the outer side of the reducer flange, adjust the PCS system clamping ring to align the side hole with the dust-proof hole, and insert the inner hexagon to tighten. After that, remove the motor shaft key.


3. Connect the motor and the reducer. Make sure that the concentricity of the output shaft of the reducer and the input shaft of the motor is the same during connection, and the outer flanges of the two are parallel. If the concentricity is inconsistent, it will cause the motor shaft to break or reducer gears to wear.


In addition, during installation, it is strictly prohibited to hit the reducer with a hammer, etc., to prevent excessive axial or radial force from damaging the bearing or gear. Be sure to tighten the mounting bolts before tightening the tightening bolts. Before installation, wipe off the anti-rust oil on the motor input shaft, positioning convex platform and the connection part of the reducer with gasoline or zinc-sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear.


Before connecting the motor to the reducer, the keyway of the motor shaft should be perpendicular to the tightening bolt. To ensure uniform force, first screw on the mounting bolts at any diagonal position, but do not tighten, then screw on the other two diagonal mounting bolts, and finally tighten the four mounting bolts one by one. Finally, tighten the tightening bolts. All tightening bolts need to be fixed and checked with a torque wrench according to the marked fixed torque data.


The installation between the reducer and mechanical equipment is similar to that of installation between the reducer and the drive motor. The key point is to ensure that the output shaft of the reducer is consistent with the concentricity of the driven part.
