    • An apparatus for forming internal gear teeth at large workpieces at a gear shaper or gear shaping machine comprising a machine bed at which there are arranged a workpiece table for chucking a workpiece and an upright or stand. The workpiece table and the stand are rotatable, relative to one another, about the workpiece axis and radially feedable relative thereto. The stand has guide means along which there can be moved to-and-fro a plunger by means of a plunger drive. An auxiliary stand is rotatably and radially displaceable about the workpiece axis upon a bearing rim which is coaxially attached at the workpiece. The auxiliary stand has a guide arrangement along which there can be moved to-and-fro, in the tooth lengthwise direction of the internal teeth, an auxiliary plunger driven by the plunger by means of a bridge arrangement.
    • 一种用于在齿轮整形器或齿轮成形机上在大工件处形成内齿轮的装置,包括机床,在该机床上设置有用于夹紧工件的工件台和竖立或支架。 工件台和支架相对于彼此可绕着工件轴线旋转并相对于其径向地进给。 支架具有引导装置,借助于柱塞驱动器可以沿着该装置将柱塞移动到其上。 辅助支架可绕工件轴线可旋转地径向移动,该轴承轮圈同轴地连接在工件上。 辅助支架具有引导装置,沿着该导向装置可以在内齿的齿长度方向上来回移动,辅助柱塞由柱塞由桥式装置驱动。
