加工直齿圆柱齿轮时多以滚柱作为定位元件,斜齿轮由于齿槽为螺旋槽,不能采用滚柱,故多采用弹性滚柱(亦即外圆经过磨削的弹簧)或钢球作为定位元件,弹性滚柱可以看成是由无数很薄的圆片柔性地联接而成。由于斜齿轮螺旋状齿槽的法面截形比端面截形窄,所以组成弹性滚柱的每个薄圆片或钢球在螺旋形齿槽中是和法面截形相接触,也就是和法向齿形相接触。精确地求斜齿轮的法向齿形非常复杂,而且通常也没有必要,在实际生产中多
When machining spur gears, rollers are mostly used as positioning elements. Helical gears can not be rollers because they are helical grooves. Therefore, the use of elastic rollers (that is, the outer cylindrical grinding springs) or steel balls as positioning Components, flexible roller can be seen as a thin countless thin flexible wafer connected together. As helical gear tooth surface of the truncated truncated truncated narrower than the end surface, so the composition of the elastic roller of each wafer or ball in the helical gullet and the truncated contact surface, that is, and the law To tooth-shaped contact. Accurately determine the helical gear normal profile is very complicated, and usually not necessary, in the actual production of more
