Installation precautions for horizontal motor reducers

Horizontal motor reducers are widely used in industrial production, and their correct installation is crucial for the normal operation and service life of the equipment. Next, we will elaborate on the precautions during the installation process of horizontal motor reducers with examples.

1、 Preparation before installation of horizontal motor reducer

1. Check the equipment

Before installation, carefully inspect the appearance of the horizontal motor reducer to see if there are any damages caused during transportation, such as shell rupture, shaft bending, etc. At the same time, check if all components are complete and if the connecting bolts are loose.

Example: A factory installed a new horizontal motor reducer without conducting a pre installation inspection. After installation, it was found that the output shaft of the reducer was bent, resulting in severe vibration during equipment operation. Eventually, the factory had to shut down and replace the reducer, causing production delays.

2. Clean the installation site

Ensure that the installation site is clean, tidy, and free of debris and dust to prevent impurities from entering the interior of the gearbox.

For example, in a food processing plant, due to inadequate cleaning of the installation site, dust enters the gearbox, causing increased gear wear and shortening the service life of the gearbox.

2、 Key points in the installation process of horizontal motor reducer

1. Calibration of alignment

During installation, it is necessary to ensure the coaxiality between the motor shaft and the input shaft of the reducer, and the deviation should be controlled within the allowable range. Tools such as a dial gauge can be used for measurement and calibration.

For example, during the installation of a horizontal motor reducer in a cement plant, there was a significant deviation in coaxiality. Shortly after operation, the coupling was damaged, which affected the production schedule.

2. Tighten the bolts

Tighten the connecting bolts according to the specified torque value, avoiding over tightening or over loosening. Tightness may cause bolt breakage, while looseness can cause loose connections, resulting in vibration and noise.
