In the reducer family, planetary reducers are widely used in servo, stepper, DC and other transmission systems due to their small size, high transmission efficiency, wide reduction range, and high precision. Its function is mainly used to reduce speed, increase torque, and reduce the load/motor moment of inertia ratio while ensuring precision transmission.

Proper installation, use, and maintenance of reducers are important steps in ensuring the normal operation of mechanical equipment. Therefore, when installing the planetary gearbox, please strictly follow the following installation and use related matters, and assemble and use it carefully.

Before installation, confirm that the motor and reducer are intact and undamaged, and strictly check whether the dimensions of each part connected to the motor and reducer match. Here are the dimensions and fitting tolerances of the motor's positioning protrusion, input shaft, and reducer groove.

Unscrew the screws on the outer dust-proof hole of the reducer flange, adjust the PCS system clamping ring to align its side hole with the dust-proof hole, and insert it into the hexagonal socket for tightening. Afterwards, remove the motor shaft key.

Connect the motor and reducer naturally. When connecting, it is necessary to ensure that the concentricity between the output shaft of the reducer and the input shaft of the motor is consistent, and the outer flanges of the two are parallel. Inconsistent alignment can cause the motor shaft to break or the gear of the gearbox to wear.

Attention: It is strictly prohibited to use hammers or other tools to strike, in order to prevent excessive axial or radial force from damaging bearings or gears. Be sure to tighten the installation bolts before tightening the tension bolts.

Before installation, wipe off the rust proof oil on the motor input shaft, positioning boss, and reducer connection parts with gasoline or zinc sodium water.

Before connecting the motor to the reducer, the keyway of the motor shaft should be perpendicular to the tension bolt. To ensure even force distribution, first tighten the installation bolts at any diagonal position, but do not tighten them, then tighten the installation bolts at the other two diagonal positions, and finally tighten the four installation bolts one by one.

Finally, tighten the tension bolt. All tightening bolts need to be fixed and checked with a torque wrench according to the indicated fixed torque data.

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