在齿轮传动中,齿轮的材料除通常选用钢以外,灰铸铁和青铜也是常用的材料。我们选用灰铸铁,是因为它具有优良的消震性、耐磨性、切削加工性。青铜的抗腐蚀性很好,故常用作与酸、硷、蒸汽等接触的齿轮材料。由于青铜的耐磨性能好,它还被用在有高速滑动的传动中(如蜗轮传动)。近几年来,在某些传动装置中,有一种用mos_2填料尼龙(mos_2-fillednylon)来代替庆铸铁和青铜的趋势。这种变化带来的最大好处是:减少了噪音,提高了啮合齿轮的工作寿命,缩短了维修时间,增加了齿轮材
In the gear transmission, the gear material in addition to the usual selection of steel, gray cast iron and bronze are also commonly used materials. We use gray cast iron, because of its excellent shock absorption, wear resistance, machinability. Bronze corrosion resistance is good, it is often used as acid, alkali, steam and other contact gear materials. Because of its good abrasion resistance, bronze is also used in high-speed sliding drives (such as worm gear drives). In some transmissions, in recent years there has been a trend of replacing mosquitos and bronze with mos_2-filled nylon. The greatest benefits of this change are: reduced noise, improved service life of meshing gears, reduced maintenance time, increased gear material
