有许多设计者断言,齿轮的纯滚动啮合是做不到的。美国加利福尼亚州的圣罗萨滚动接触齿轮公司正在从事发展的却正是这种纯滚动接触的新齿轮系统。据滚动接触齿轮的专利发明者说:“试验表明,这种新的齿轮装置比普通渐开线更经久耐用,并且可能在许多齿轮装置的应用中代替渐开线齿轮,可能还会与 V 形皮带和同步皮带竞争”。因为滚动接触齿轮的耐磨性至少能提高十倍。这就意味着用塑料、粉末冶金等模铸齿 There are many designers who assert that purely rolling gear meshing can not be done. The Santa Rosa rolling contact gear company in California, USA, is working on a new gear system for this purely rolling contact. According to the patented inventor of a rolling contact gear, “Tests have shown that this new gear unit is more durable than regular involutes and may replace involute gears in many gear applications, possibly with V-shaped Belt and timing belt competition. ” Because the rolling contact gear wear resistance can be increased at least tenfold. This means using plastic, powder metallurgy and other die-casting teeth
