Three Steps of Planetary Gear Reducer Installation

- Aug 17, 2019-

Proper installation, use and maintenance of the reducer is an important part of ensuring the normal operation of mechanical equipment. Therefore, when installing the planetary reducer, be sure to carefully assemble and use it in strict accordance with the following installation and use.

 

First step, Before installation, confirm whether the motor and reducer are intact, and strictly check whether the dimensions of the parts connected to the reducer are matched. Here are the dimensions and matching tolerances of the positioning boss, input shaft and reducer groove of the motor.

Second step, Unscrew the screw on the outer dust-proof hole of the reducer flange, adjust the clamping ring of the PCS system so that the side holes are aligned with the dust-proof holes, and insert the hexagon socket into the hexagon. After that, remove the motor shaft key.

Third step, Connect the motor to the gearbox naturally. When connecting, it must be ensured that the output shaft of the reducer is concentric with the input shaft of the motor, and the outer flanges of the two are parallel. As the heart is inconsistent, it will cause the motor shaft to break or the reducer gear to wear.

 

In addition, it is strictly forbidden to hit with a hammer or the like during installation to prevent damage to the bearing or gear due to excessive axial force or radial force. Be sure to tighten the mounting bolts before tightening the tightening bolts. Before installation, wipe the anti-rust oil of the motor input shaft, positioning boss and reducer connection 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 motor shaft keyway should be perpendicular to the tightening bolt. To ensure uniform force, first screw the mounting bolts at any diagonal position, but do not tighten them. Then screw on the mounting bolts at the other two diagonal positions and finally tighten the four mounting bolts one by one. Finally, tighten the tightening bolts. All tightening bolts must be fixed and inspected with the torque wrench according to the indicated fixed torque data.

The correct installation between the reducer and the mechanical equipment is the correct installation between the reducer and the drive motor. The key is to ensure that the output shaft of the reducer is concentric with the shaft of the driven part. Planetary reducer torque calculation

 

Planetary reducer torque = 9550 × motor power ÷ motor power input revolutions × speed ratio × use efficiency (95%)
