(一) 我们曾讨论了非径向槽转位机构的几何关系,运动和动力计算问题,在本文内想讨论一下这种机构的误差问题——由机构元件的尺寸误差引起的运动误差问题。在某些情况下,机构的允许运动误差已经规定,需进而确定机构各元件的尺寸误差,以供设计和制定元件技术规范的参考。机构运动误差的研究对精密机械具有十分重要的意义。在研究转位机构的运动学时,曾假定机构各元件的几何尺寸是绝对准确的,并且绝
(A) We discussed the geometric, kinematic and dynamic calculation of non-radial slot indexing mechanisms. In this paper, we will discuss the error of such a mechanism - the problem of motion errors caused by the dimensional errors of the mechanism components. In some cases, the agency has allowed the movement error has been required to determine the size of the various components of the organization for the design and development of component specifications for reference. Research on the mechanism motion error is of great significance to precision machinery. In studying the kinematics of indexing agencies, it has been assumed that the geometrical dimensions of the various components of the agency are absolutely accurate and must
