我们先后在电封闭和开式水力测功器加载试验台上,对NPL-350变长线齿轮减速器进行了稳定负荷下的承载能力试验。结果表明,变长线齿轮减速器的接触强度比同参数的渐开线齿轮减速器的额定值高3倍以上。相同破坏情况下的实际承载能力比渐开线齿轮高1.7倍左右。变长线齿轮传动的承载能力仍然受接触强度(点蚀)的限制,而在 We have in the electric closed and open hydraulic dynamometer loading test rig, variable length gear reducer NPL-350 under a steady load carrying capacity test. The results show that the contact strength of the variable-length gear reducer is more than 3 times higher than that of the involute gear reducer with the same parameters. The same under the destruction of the actual carrying capacity than involute gear 1.7 times higher. The load capacity of variable-length gear drives is still limited by the contact strength (pitting), while at
