优化重型变速箱副箱齿座与输出轴配合

Optimization Operation of the Side-box Gear Seat of the Heavy Duty and the Output Shaft

在重型变速箱中齿侧间隙的合理控制,对变速箱内部齿轮以及变速箱整体寿命非常关键。在副箱结构为双中间轴且同步器为锁环式的变速箱中,同步器齿座与输出轴为矩形花键联接,齿座与输出轴配合是否牢固,影响到副箱高低挡切换以及变速箱整体性能。

The proper control of side gear clearance is vital important to the life time of gears and the whole body of the heavy duty gearbox.Given that the gear seat of the synchronizers and output shaft are connected by the rectangular spline in the gearbox with double-layshaft range part and the lock ring synchronizers,whether the gear seat and output shaft match reliably,which would affect the high-low switch of the range part and the whole performance of the gearbox.
