七八年,我国学者首创了变长线齿轮传动理论。七九年我厂进行了应用研究,成功地研制出变长线齿轮减速器。(图1)八○年三月正式投入工业试验,经过半年的生产运转,证明变长线齿轮承载能力远比渐开线齿轮大,而噪音又比单圆弧齿轮小。加之其加工、测量简便,所以具有广泛应用的前景。 In 1978, Chinese scholars pioneered the variable-length gear transmission theory. In 1979 I applied our research, successfully developed a variable-length gear reducer. (Figure 1) In March 1980 formally put into industrial test, after six months of production and operation, proved that variable-length gear carrying capacity is much larger than the involute gear, and the noise is smaller than the single arc gear. Coupled with its processing, measurement is simple, so has a broad application prospects.
