文变位齿轮传动应用有着良好的效果和显著的经济效益。它具有承载能力强、寿命长等优点，国外在磨机上用大变位齿轮传动代替标准齿轮传动，而国内由于加工方法和加工难度问颗．很少应用。1采用大变位齿轮的理论依据国内外资料显示，磨机大、小齿轮大多是由于磨损而造成齿厚减薄 Text variable gear transmission applications have good results and significant economic benefits. It has a strong carrying capacity, long life, etc., the foreign mill in the use of large displacement gear instead of standard gear transmission, and the domestic due to processing methods and processing difficult to ask questions. Rarely used. A large displacement gear theory based on domestic and foreign data show that the mill, the pinion is mostly due to wear and tear caused by tooth thickness reduction
