Worm gears generally use more copper. What kind of worm gear is better for worm gear reducer? Why? However, there are many kinds of copper. How to choose? When the worm gear is worn: The worm gear is generally made of tin bronze. The matched worm material is usually hardened to hrc45 ~ 55 with 45 steel. It is also commonly hardened to hrc50-55 with 40C. During the normal operation of the reducer, 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. If the wear speed is fast, it is necessary to consider whether the selection of reducer is correct, whether there is overload operation, the material of worm gear, assembly quality or service environment. In case of heating and oil leakage of worm gear reducer: In order to improve the efficiency of worm gear reducers, non-ferrous metals are generally used as worm gears, and the worm is made of hard steel. Because it is a sliding friction transmission, it will produce high heat during operation, resulting in differences in thermal expansion between various parts and seals of the reducer, resulting in gaps on various mating surfaces, and the oil becomes thinner due to the increase of temperature, Easy to cause leakage.
Our products are mainly exported to Japan, the United States, Germany, Southeast Asia and other countries and regions. Our customers include many OEM customers specializing in construction machinery. We have partnered with several of the Fortune 500 companies to become one of their major foundry suppliers in China.
