外啮合和内啮合径向槽转位机构(马氏机构)的理论和计算问题,在一些技术文献中已经有所阐明,近年来对这些被广泛应用在机床制造业(如组合机床中,多轴自动车床中,单轴转塔自动车床中等)中的转位机构已有人开始进行实验研究,但是这些研究还远远没有达到完善的程度,例如对内啮合转位机构的效率问题就没有进行过理论的和实验的研究。苏联学者教授建议,在马氏转位机构实际计算时,机构的效率假定为常数[1],当然这是近似的假定,实际上马氏转位机构的效率是一个变数,它的大 The theoretical and computational problems of external meshing and internal meshing radial groove indexing mechanism (Markovian mechanism) have been clarified in some technical documents. In recent years, these are widely used in machine tool manufacturing industry Axis automatic lathes, single-axis turret automatic lathe medium) indexing mechanism has been started in experimental studies, but these studies are far from perfect, for example, the efficiency of the internal engagement index mechanism has not been carried out Through theoretical and experimental research. Soviet scholar professor suggested that in the actual calculation of the Markov indexing agency, the agency’s efficiency is assumed to be constant [1], of course, this is an approximate assumption, in fact Markov indexing agency efficiency is a variable, its large
