目前,应用在汽车主减速器上的锥齿轮,多为美国格里森制渐缩齿圆弧锥齿轮和瑞士奥利康制等高齿延伸外摆线锥齿轮以及这两种齿制的双曲面齿轮。对锥齿轮传动安装的最根本要求是节锥面相切、节锥顶点重合。螺旋锥齿轮是成对制造和使用的,其加工、安装的检查,通常延用成对齿轮的检验方法,即检查成对齿轮的齿面接触区、齿侧间隙及噪音。齿面接触区对齿轮的平稳运转、使用寿命和噪音有直接影响。所以,齿面接触区是衡量
At present, the bevel gear used in the main reducer of the automobile is mostly the American Gleason’s tapered bevel circular bevel gear and the Swiss Aulikang equal height tooth extended external hypocyclic bevel gear, and the two kinds of gear made hyperboloids gear. The most fundamental requirement for bevel gear drive installation is taper section tangency, section cone vertex coincidence. Spiral bevel gears are made and used in pairs. Inspection of their machining and installation usually follows the test of pairs of gears, ie the contact area of tooth surfaces, flank clearance and noise of the pair of gears. Tooth contact area on the smooth running gear, life and noise have a direct impact. Therefore, the contact area of the tooth surface is a measure
