本文介绍了小模数精密齿轮在滚削加工中,滚齿机分度传递齿轮D的误差对被加工齿轮的齿形误差和周节累积误差的影响。通过公式、图表等形式对齿形误差、周节累积误差进行了计算和分析,找出了合理的使用数据。还叙述了滚刀切削刃数、排屑槽数、被加工齿轮齿顶余量和切削转矩变动的关系,以及对被加工齿轮精度的影响。还简要介绍了小模数精密齿轮的测量问题。
This article describes the small module precision gears in hobbing, gear hobbing machine D transmission error of the gear to be machined gear tooth error and the impact of the cumulative error. Through the formula, chart and other forms of tooth-shaped error, the cumulative error of the week was calculated and analyzed to find a reasonable use of data. The relationship between hob cutting edge number, chip flute number, gear tooth top allowance and cutting torque variation is also described, and the influence on the precision of the gear to be machined is also described. Also briefly introduced the measurement of small module precision gear.
