一、前言近年来,用于传递机械功率的齿轮装置的输出功率与重量的比值一直在升高。这种趋向固然是由于齿轮材料和润滑剂改进的结果,但另一方面,也不能忽视齿轮设计制造技术进步所起的重大作用。近来,该领域在设计方面的进步之一,可以说是由于使用了高啮合率齿轮(HCRG),提高了齿轮装置的承载能力。所谓高啮合率齿轮,是指在齿轮啮合循环过程中,总有2对或者3对轮齿同时进入啮合状态的齿轮。由于这种齿轮所传递韵载荷分散在
I. Introduction In recent years, the ratio of output power to weight of gear units used to transmit mechanical power has been on the rise. This trend, of course, is due to improvements in gear materials and lubricants, but on the other hand, the significant role of gear design and manufacturing technology can not be overlooked. Recently, one of the advancements in design in this field can be attributed to the use of a high meshing gear (HCRG) to increase the load capacity of the gear unit. The so-called high meshing gear, refers to the gear meshing cycle, there are always 2 or 3 pairs of gear teeth into the state at the same time into gear. The rhyme load transmitted by this gear is dispersed
