Solution to the wear and tear of RV reducer
Worm gear wear of RV reducer: The worm gear is generally made of tin bronze, and the matched worm material is generally hardened with 45 steel to HRC45-55, and 40C: hardened HRC50-55 is commonly used, and it is ground by a worm grinder to a roughness of RaO. 8 fcm, When the reducer is in normal operation, the worm is like a hardened "file", constantly filing the worm gear, causing the worm gear to wear.

　　 Generally speaking, this kind of wear is very slow. Some reducers in a certain factory can be used for more than 10 years. If the wear rate is fast, it is necessary to consider whether the selection of the reducer is correct, whether there is overload operation, the material of the worm gear, the assembly quality or the use environment and other reasons.

Solution: selection of lubricants and additives. Worm gear reducers generally choose 220 # gear oil, for some reducers with heavier load, frequent starting, and poor use environment. Use some lubricating oil additives. When the reducer stops running, the gear oil is still attached to the surface of the gear to form a protective film to prevent heavy load, low speed, high torque, and metal-to-metal contact during startup.

　　 The solution to the above RV reducer wear is introduced.
