    • A spindle (60) for a machine tool comprising a rear spindle portion (62) and a forward spindle portion (64) with each of the rear spindle portion and the forward spindle portion being rotatable about the same axis relative to one another. The inventive spindle includes one or more spring elements (68) extending between the rear spindle portion and the forward spindle portion whereby with the forward spindle portion and the rear spindle portion rotating at a predetermined amount and with the rotation of the forward spindle portion being constrained at that amount, an additional rotation applied to the rear spindle portion results in a deflection of the springs thereby effecting a torque between the forward and the rear spindle portions. The present invention also includes a control method which has as its objective to control the position of, not the torque applied to, one of the spindles, usually the gear member spindle. In this method, the gear member spindle position is controlled relative to the pinion member spindle position by a computer numerical control (CNC). As the pinion member is turned at some speed, the gear member is kept in coordination with the pinion (according to their ratio) by the CNC control. The gear member spindle can be commanded to include additional rotational components which, in effect, advance or retard the gear rotation relative to the pinion.
    • 一种用于机床的心轴(60),其包括后心轴部分(62)和前心轴部分(64),后心轴部分和前心轴部分中的每一个可相对于彼此绕同一轴线旋转。 本发明的心轴包括一个或多个在后心轴部分和前心轴部分之间延伸的弹簧元件(68),由此通过前心轴部分和后心轴部分以预定量旋转,并且前心轴部分的旋转被约束 以这种量,施加到后心轴部分的附加旋转导致弹簧的偏转,从而实现前和后心轴部分之间的扭矩。 本发明还包括一种控制方法,其目的在于控制施加于其中一个主轴(通常是齿轮构件主轴)的位置而不是扭矩。 在这种方法中,通过计算机数控(CNC)相对于小齿轮主轴位置控制齿轮主轴位置。 当小齿轮部件以某种速度转动时,齿轮部件通过CNC控制与小齿轮(根据它们的比例)保持配合。 齿轮构件主轴可以被命令包括额外的旋转部件,其实际上相对于小齿轮推进或延迟齿轮旋转。
