摘要
齿轮副侧隙是齿轮机械设计和齿轮啮合时的重要参数,为了提高齿轮副侧隙的测量精度,解决由于结构所限无法实现两个齿轮上同时安装圆光栅光电码盘作为角度传感器的齿轮副侧隙的测量问题,提出了一种基于光电角度测量模块的齿轮侧隙自动测量技术,在主动齿轮上安装微型光电角度测量模块,从动齿轮上安装光电编码器,来采集两个齿轮的角度,并进行数据处理和软件控制,实现了齿轮副侧隙的自动测量;给出了影响该自动检测系统的主要误差来源,进行了误差分析;最后通过实验给出了一种锥齿轮副侧隙的自动测量结果。
Gear pair gap is an important parameter in gear mechanical design and gear meshing.In order to improve the measurement precision of the gear pair gap and solve the problem that it is impossible to measure the gap of the gear pair which is equipped with a circular grating photoelectric code disk on both gears as an angle sensor due to the limitation of structure?an automatic measuring technique based on the photoelectric angle measurement module is proposed for measuring the gap of the gear pair.To collect the angles of the two gears?a micro-photoelectric angle measurement module is installed on the driving gear and a photoelectric encoder is mounted on the driven gear?and then data processing and software control are performed to realize the automatic measurement of the gear pair gap.The main error sources affecting the automatic detection system are given?and an error analysis is carried out.Finally?the automatic measurement results of the gap of bevel gear pair are given through experiments.
