齿轮电跑合是利用在齿轮传动时,且在齿轮间注以一定油量时齿轮间便有油膜形成,从而有变化的间隙接通电源,使齿轮间先将接触的区域进行放电,放电由此逐渐向齿长和齿高扩展,达到齿轮电跑合的目的。由于其放电间隙在电源参数确定后为一较小恒定值,故电跑合齿轮便具有良好的加工精度。实践证明,经电跑合的齿轮其齿长及齿 Running gear is used in the gear transmission, and the gear between the injection of a certain amount of oil will have a film of oil between the gears, so there is a change in the gap connected to the power source, the gear between the first contact area discharge, discharge by the This gradually extended to the tooth length and tooth height, to achieve the purpose of gear running together. Because of its discharge gap in the power parameters to determine a small constant value, so the electric running gear will have a good processing accuracy. Practice has proved that the gear running through the teeth of its gear length and teeth
