大变位齿轮自从1968年在磨机、机械化立窑上应用以来,取得了良好的效果。使用厂普遍反映这种齿轮运转平稳、噪音小,承载能力高、使用寿命长。一般来说,可提高使用寿命2～5倍。但是,在采用滚齿加工时往往会出现顶刀、烧刀、边刀刮齿等现象。于是有人便认为这种大变位齿轮加工复杂,不能用标准滚刀加工。使这种齿轮的推广受到一定限制。实际上,大变位齿轮也是渐开线齿轮,因此,可用 Great changes gear since 1968 in the mill, mechanized shaft kiln application, and achieved good results. The use of plant generally reflects the smooth operation of this gear, low noise, high load capacity, long service life. In general, can improve the service life of 2 to 5 times. However, the use of hobbing processing often appear top knife, knife, knife edge scraping and so on. So some people think that such a large change gear machining complex, can not use standard hob processing. The promotion of such gears is subject to certain restrictions. In fact, the large variable gear is also an involute gear and therefore, is available
