How to adjust the coaxiality between the reducer and the motor?

When the reducer takes over, check that the centerline of the motor takeover is the same as the centerline. And install the dial indicator, the rotary reducer takes over a circle, and record the dial indicator at the upper and lower points. (If the reducer is not suitable for rotation, you can attach the magnetic base unit to the motor and rotate the motor shaft. Yes) Calculate the difference between the upper and lower points of the dial gauge. Add a thick washer to the local area of the four-foot screw of the motor, and the edge value is 0.10~0.15 mm. The experience value is the time of the dial indicator. The motor foot screw is not tightened to cause an attack; in the case of rigid reception or poor reception compensation, together with the high-speed operation of the machine, the temperature difference and intermittent state of the reducer and mechanical bearing seat during operation are large, and the demand is based on the reducer and The empirical calculation of the bearing housing. During operation, due to the increase in temperature, the height of the nest is caused to increase.

More and more people are beginning to pay attention to the reasons for the cracking of the high-speed shaft of the hard gear reducer. The following are some points of view: Reasons for cracking of the high-speed shaft of the hardened gear reducer: There are problems with the installation and operation of the reducer In the planning of the hardened gear reducer, the large mismatch of the shaft diameters of the motor and the reducer is a problem. If there is a difference in the coaxiality between the motor shaft and the reducer shaft, the radial force will increase to the coupling, and the shaft diameters will be different, resulting in different modulus of the bending part. The additional radial forces generated by the coupling also have additional bending moments, i.e. stresses, for the risk curves of both shafts. If the bending stress on the shaft of the reducer is much greater than that of the motor shaft, cracking of the shaft of the reducer is inevitable.
