一、概述砂轮主轴是磨齿机中的关键零件之一。砂轮主轴本身的精度和其装配精度对磨齿机磨齿质量有很大的影响,特别是轴颈间的尺寸精度、光洁度、形位公差(不同轴度、不圆度等)比一般零件技术要求高。为了使其精度能够长期保持稳定,这与主轴的结构刚性、材料选择、热 First, an overview Wheel spindle is one of the key parts in the grinding machine. The precision of grinding wheel spindle itself and its assembly precision have a great influence on the grinding quality of grinding machine. Especially, the dimensional accuracy, smoothness and form tolerance between the journal (non-coaxiality, out-of-roundness, etc.) High technical requirements. In order to make its accuracy can be long-term stability, which is the structural rigidity of the spindle, material selection, heat
