There are three solutions to the common problems of worm gears :

Solution one, to ensure assembly quality

You can purchase or make some special tools. When disassembling and installing the parts of the reducer, try to avoid hitting with other tools such as hammers. When replacing gears and worm gears, try to use original parts and replace them in pairs. When assembling the output shaft, pay attention to it. Tolerance fit; use a release agent or red dan oil to protect the hollow shaft to prevent wear and rust or to match the area scale, which is difficult to disassemble during maintenance.

Solution 2, lubricant selection

The worm gear reducer generally uses 220# gear oil. For heavy-duty trucks with heavy load, frequent start and poor use environment, some lubricating oil additives can be used to make the gear oil still adhere to the gear surface when the reducer stops running, forming protection. Membrane to prevent heavy load, low speed, high torque and direct contact between metals at start-up. The additive contains a seal regulator and a leak preventer to keep the seal soft and elastic, effectively reducing oil leakage.

Solution three, reducer installation options

When possible, do not use a vertical installation. When installing vertically, the amount of lubricating oil added is much more than that of horizontal installation, which may cause heat generation and oil leakage of the reducer.
