一、前言小模数齿轮的精密测试.是确保其质量必不可少的重要手段.小模数齿轮绝大部份采用渐开线齿形.而齿形误差对于齿轮传动时的瞬时速比变化以及噪音、冲击或振动等有密切关系.它是评定齿轮工作平稳性的主要指标.
I. INTRODUCTION The precision testing of small modulus gear is an important means to ensure the quality of it.Most involute gear adopts involute tooth shape.The change of gear speed to the change of instantaneous speed ratio As well as noise, shock or vibration, etc. It is the main index to evaluate the work stability of gears.
