一、接触迹测量运动分析两个圆柱斜齿轮啮合时,如果它们的轴线不平行,则称为螺旋齿轮啮合。把相错轴传动中,轮齿为渐开线螺旋面的齿轮,叫做渐开线螺旋齿轮。螺旋齿轮啮合的任一瞬时,相啮两渐开线螺旋齿轮的齿面仅在一点接触,在传动过程中一个齿面上接触点移动的轨迹称为接触迹,也有称其为法向啮合齿形。接触迹是研究 First, the contact trace measurement motion analysis Two cylindrical helical gears meshing, if their axes are not parallel, then known as the helical gear meshing. The wrong axis drive, the involute helical gear teeth, called involute helical gear. Helical gear meshed any instantaneous, intermeshing two involute helical gear tooth surface contact at only a point in the transmission process, the contact point of a tooth surface moving track is called the contact track, also known as the normal meshing teeth shape. Contact trace is research
