Solution of common problems of worm gear and worm

Guarantee assembly quality. Can purchase or make some special tools, when removing and installing the reducer parts, try to avoid knocking with hammers and other tools; when replacing gears, worm gears, try to use original parts and replace in pairs; when assembling the output shaft, pay attention to Tolerance fit; Use anti-adhesive agent or reddish oil to protect the hollow shaft to prevent rust or area scale and it is difficult to disassemble when repairing. 2. Selection of lubricants and additives. The worm gear reducer generally uses 220# gear oil. For heavy-duty, frequent-starting, and poorly-used gearboxes, some lubricant additives may be selected so that the gear oil still adheres to the surface of gears when the gear reducer stops operating, forming a protection. Membrane to prevent heavy load, low speed, high torque and direct contact between metals during startup. The additive contains a seal conditioner and anti-leakage agent to keep the seal ring soft and flexible, effectively reducing oil leakage. 3. Selection of reducer mounting position. If the location allows, try not to use vertical installation. In vertical installation, the amount of lubricant added is much more than that of horizontal installation, which can easily cause heat generation and oil leakage of the reducer. 4. Establish a lubrication maintenance system. The speed reducer can be maintained according to the “five set” principle of lubrication work, so that each speed reducer is inspected by the responsible person regularly and it is found that the temperature rise is obvious. If the temperature exceeds 40° C. or the oil temperature exceeds 80° C., the quality of the oil drops or the oil When more copper powder is found and unusual noise is generated, stop using it immediately, repair it in time, troubleshoot it, and replace the oil. When refueling, pay attention to the amount of oil and ensure that the reducer is properly lubricated.
