What should I do if the worm gear of the worm gear reducer is worn?

The worm gear is generally made of tin bronze, and the matching worm material is hardened to HRC45 with 4555 steel, or 40Cr hardened to HRC5055 and then ground to a roughness of Ra0.8μm by a worm grinder.Reducers wear out slowly during normal operation, and some reducers can be used for more than 10 years.If the wear rate is fast, it is necessary to consider whether the selection is correct, whether it is overloaded, and the material of the worm gear, the quality of assembly or the use environment.
Worm gear reducers generally use 220# gear oil. For reducers with heavy loads, frequent starting 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 a protective effect. Membrane to prevent direct metal-to-metal contact during heavy loads, low speeds, high torque and start-up.The additive contains seal ring adjuster and anti-leakage agent, which keeps the seal ring soft and elastic and effectively reduces the leakage of lubricating oil.
