Daily Maintenance of Worm Gearbox

After the worm gearbox is completed, it is officially put into use, so what routine maintenance work needs to be done during the use of the gearbox? as follows:

1. The working place, transmission efficiency, load capacity, and lubricant brand used by the worm gear reducer must comply with the values specified in its specifications.

2. The height of the lubricating oil surface of the worm gear reducer head box should be within the height range required by the design when the worm gear is officially put into use. And check the oil supply of each lubricating oil point at any time.

3. Regularly check the impurities, moisture, and viscosity changes contained in the lubricating oil. If it is found that the standard is exceeded or not up to standard, the lubricant should be treated in time, and the bearing and oil pool should be carefully washed while changing the lubricant.

4. During normal operation of the worm gear reducer, the temperature of the bearing and the oil sump and the noise of the reducer should be checked. If an abnormal situation is found, the cause should be stopped immediately, and it can be put into use again after the abnormality is eliminated.

5. Regularly check the tooth surfaces of the internal gears of the worm gearbox. If there is corrosion, scratches, glued or broken teeth on the tooth surface, it must be shut down immediately and processed.
