一、概述近年,针摆行星传动应用于机械行业以来,由于它的传动比大,体积小,重量轻,机构紧凑等显著优点为人们所欢迎。然而它的加工制造困难,特别是摆线齿轮加工更为困难,给针摆行星传动的推广应用带来一定的局限性。这样齿差行星传动的出现引起了人们极大的兴趣。在矿山机械方面应用也越来越多,如联合掘进机,外回转凿岩机,齿差慢动绞车,梭车等机械设备上都有用齿差传动的。我
I. Overview In recent years, the needle swing planetary gear used in machinery industry, because of its transmission ratio, small size, light weight, compact body and other significant advantages for the people welcome. However, its processing and manufacturing difficulties, especially the cycloidal gear processing more difficult to promote the application of pin cycloid planetary transmission has brought some limitations. This tooth difference planetary transmission has aroused great interest. More and more applications in the mining machinery, such as joint boring machine, rocking machine outside the rotary, gear differential slow winch, shuttle and other mechanical equipment are useful toothed drive.
