确定渐开线表面的参数也会遇到测量曲面所固有的很多困难。同时,对这种表面的制造精度又提出了极严格的要求。用来形成绝大多数齿轮齿侧面的渐开线齿形是确定各种机床、机器和机构传动质量的最重要因素。齿形误差 Determining the parameters of an involute surface also encounters many difficulties inherent in measuring the surface. At the same time, very strict requirements have been placed on the manufacturing accuracy of such surfaces. The involute toothing used to create the vast majority of gear tooth flanks is the most important factor in determining the drive mass of various machine tools, machines and mechanisms. Tooth shape error
