花键磨削的特点之一,是高速旋转的砂轮轴中心线与被磨削花键中心线相垂直。M8612花键磨床砂轮轴的两端装有精密的径向推力球轴承,砂轮轴在高速旋转时,因摩擦温升增高,轴向上逐渐伸长。而磨削花键时是一个齿一个齿的分度磨削,随着轴向上的伸长,成形砂轮对称中心则慢慢偏离被磨花键中心线,这个误差会敏感的反映到被磨削花键上,使花键齿形、相邻误差和积累误差等技术要求增大或超差。
One of the features of spline grinding is that the centerline of the grinding wheel shaft rotating at a high speed is perpendicular to the centerline of the splined shaft. M8612 spline grinding wheel shaft at both ends equipped with precision radial thrust ball bearings, grinding wheel shaft at high speed due to increased friction temperature, the axial elongation. Grinding the spline is a tooth of a tooth indexing grinding, with the axial elongation, forming the wheel center of symmetry is slowly away from the spline centerline, the error will be sensitive to be worn Cut the spline, the spline tooth shape, adjacent errors and accumulation of errors and other technical requirements increase or exceed the poor.
