How to install the worm gear reducer correctly?

  Due to the improper operation of some friends when using the worm gear reducer, the output shaft of the reducer was broken, causing the enterprise to suffer unnecessary losses.

  First: Before installation, confirm whether the motor and the reducer are in good condition, and strictly check whether the dimensions of the parts connecting the motor and the reducer match. Here are the dimensions and matching tolerances of the positioning boss of the motor, the input shaft and the groove of the reducer .

  Second: Unscrew the screw on the dustproof hole on the outer side of the reducer flange, adjust the PCS system clamping ring so that the side hole is aligned with the dustproof hole, insert the hexagon socket and tighten.After that, remove the motor shaft key.

  Third: connect the motor with 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 are consistent, and the outer flanges of the two are parallel.Inconsistent concentricity will cause the motor shaft to break or the reducer gear to wear.

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