    • Thus, the present disclosure includes a method of producing a weight-optimized pneumatic tire rim having rotationally-symmetrically partially different wall thickness. The steps include: providing a tube section having a first wall thickness and two end sides; leveling the first wall thickness starting from the two end sides over a defined rotationally-symmetrical area thereby forming two flanks by precontouring, each of the flanks having a second wall thickness, and pushing tolerance-caused excess material of the flanks into a well base zone between the two flanks; and contouring the flanks by pressure rolling while drawing each of the flanks toward an end area of each of the flanks and reducing the thickness of each of the flanks partially differently to predetermined measurements. The present disclosure also includes a device to implement the method.
    • 因此,本公开内容包括制造具有旋转对称部分不同壁厚的重量优化的充气轮胎轮辋的方法。 这些步骤包括:提供具有第一壁厚和两个端侧的管段; 使第一壁厚从两端侧开始在限定的旋转对称区域上,从而通过预成形形成两个侧面,每个侧面具有第二壁厚度,并且将公差引起的侧面的多余材料推入井底区域 两侧之间; 并且通过压力滚动来轮廓化侧面,同时将每个侧面朝着每个侧面的端部区域拉伸,并且与预定的测量部分地不同地减小每个侧面的厚度。 本公开还包括实现该方法的设备。

    • A tool for producing a gear part having external toothing using a method of shaping by compression or by rolling. Said tool comprises a receiving tool for supporting the work piece which is impinged upon by a projection. Said receiving tool is driven to perform a rotational movement. The tool includes a roller pivotal about an axis (Y) that is parallel to the axis (X) of the rotating receiving tool which hold the work piece. The roller can be adjusted in the direction of its Y axis in relation to the work piece. It is subdivided in the direction of its Y axis in order to carry out the compression method. The tooth height of the individual shaping areas increases while the crown circle remains the same across all shaping areas. The root radius of the individual shaping areas decreases and the tooth depth increases from one shaping area to the next shaping area. As a result, the tooth thickness at the root circle increases in all of the shaping areas.
    • 一种用于通过压缩或滚动来形成具有外齿的齿轮部件的工具。 所述工具包括用于支撑被突出物撞击的工件的接收工具。 所述接收工具被驱动以执行旋转运动。 该工具包括绕与保持工件的旋转接收工具的轴线(X)平行的轴线(Y)枢转的辊子。 辊子可以相对于工件在其Y轴方向上进行调节。 为了执行压缩方法,将其沿Y轴的方向分割。 各个成形区域的牙齿高度增加,而冠圆圈在所有成形区域保持不变。 各个成形区域的根部半径减小,并且齿深度从一个成形区域增加到下一个成形区域。 结果,在所有成形区域中,根圆处的齿厚度增加。
