Installation method
In the reducer family, planetary reducer is widely used in servo, stepping, DC and other transmission systems because of its small size, high transmission efficiency, wide deceleration range and high precision. Its function is to reduce the speed, increase the torque and reduce the load / motor moment of inertia ratio on the premise of ensuring the precision transmission. In the past few years, when some users use the reducer, due to illegal installation and other factors, the output shaft of the reducer is broken, which makes the enterprise suffer unnecessary losses. Therefore, in order to better help the majority of users make good use of the reducer, I will introduce to you in detail how to correctly install the planetary reducer. Correct installation, use and maintenance of reducer is an important link to ensure the normal operation of mechanical equipment. Therefore, in the installation of planetary reducer, please be sure to strictly follow the following installation and use related matters, carefully assemble and use.
The first step
Before installation, confirm whether the motor and reducer are in good condition, and strictly check whether the dimensions of the parts connecting the motor and reducer match. Here are the dimensions and matching tolerances of the positioning boss, input shaft and reducer groove of the motor.
Step two
Screw down the screw on the outer dust hole of the reducer flange, adjust the PCS system clamping ring to align the side hole with the dust hole, insert the inner hexagon and tighten it. After that, remove the motor shaft key.
The third step
Connect the motor and reducer naturally. When connecting, the concentricity of the output shaft of the reducer and the input shaft of the motor must be consistent, and the outer flange of the two must be parallel. If the centrality is not consistent, the motor shaft will be broken or the reducer gear will be worn.
In addition, it is strictly forbidden to strike with hammer during installation to prevent bearing or gear from being damaged by excessive axial force or radial force. Be sure to tighten the mounting bolt before tightening the tightening bolt. Before installation, wipe the antirust oil of 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 with the reducer, the keyway of the motor shaft should be perpendicular to the tightening bolt. In order to ensure uniform stress, first screw on 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 tension bolt. All tightening bolts shall be fixed and checked with torque wrench according to the marked fixed torque data.
The correct installation between reducer and mechanical equipment is similar to that between reducer and drive motor. The key is to ensure the concentricity of the output shaft of the reducer is consistent with the shaft of the driven part.
