Planetary reducers are widely used in servo, stepping, DC and other transmission systems due to their small size, high transmission efficiency, wide deceleration range, high precision and many other advantages.Its function is to reduce the rotation speed, increase the torque and reduce the load/motor moment of inertia ratio under the premise of ensuring precise transmission.In the past few years, some users have broken the output shaft of the reducer due to illegal installation and other human factors when using the reducer, causing the company to suffer unnecessary losses.Therefore, in order to better help the majority of users to use the reducer, I will introduce you in detail how to install it correctlyPlanetary reducer.
The correct 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, please strictly follow the following installation and use related matters, and carefully assemble and use it.
1. Before installation, confirm whether the motor and reducer are intact, and strictly check whether the dimensions of the parts connecting the motor and the reducer are matched. Here are the dimensions and tolerances of the positioning boss of the motor, the input shaft and 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 naturally.When connecting, it must be ensured that the concentricity of the output shaft of the reducer and the input shaft of the motor is consistent, and the outer flanges of the two are parallel.If the center is inconsistent, it will cause the motor shaft to break or the gear of the reducer to wear.
In addition, during installation, it is strictly forbidden to hit with a hammer, etc., to prevent excessive axial or radial force from damaging the bearings or gears.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 boss 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.
4. 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 inspected with a torque wrench according to the marked fixed torque data.
5. The correct installation between the reducer and mechanical equipment is similar to the correct installation between the reducer and the drive motor.The key is to ensure that the concentricity of the output shaft of the reducer and the driven part of the shaft is consistent.
