    • A tensioning device for attraction mechanism including a receiving and mounting housing, a roller carrier pivotably connected to the mounting housing, a bearing which radially supports the roller carrier relative to the mounting housing, a spring between the roller carrier and the mounting housing for applying a tensioning force, and a damping device. The damping device includes a damping bush which, by friction, dampens any movement between the roller carrier and the mounting housing in such a way that damping is greater in the direction of an increasing tension force than in the direction of decreasing tension force. A flat band spring applies the friction force to the damping bush. The flat band spring is secured, at a first end, to the receiving and mounting housing in a rotationally fast way, and at a second end to the damping bush in a rotationally fast way.

    • The present invention relates to an apparatus for machining workpieces (W1 to W4) by stock removal, in particular the main (a1 to a5) and/or connecting rod bearing journals (b1 to b4) of crankshafts. For this purpose the apparatus is equipped with at least two guideways (7, 8) which are distanced from one another and are arranged parallel with respect to one another and on which at least one workpiece fixture (9, 10) holding a workpiece (W1to W4) each can be moved from a transfer position (P1, P2) to a working position (A1 to A6), and with two discoid cutters (17, 18, 21) of which each can be moved on a cutter guideway (13, 14, 19), which is arranged between the guideways (7, 8), from a first working position (A1, A2, A5) in which it works on the workpiece (W1, W3) held by the first workpiece fixture (9) to a second working position (A3, A4) in which it works on the workpiece (W2, W4) held by the second workpiece fixture (10). The apparatus in accordance with the invention allows performing the machining with high precision of the workpieces.
    • 本发明涉及一种用于通过原料去除加工工件(W1至W4)的装置,特别涉及曲轴的主(a1至a5)和/或连杆轴承轴颈(b1至b4)。 为此,该装置配有至少两个相互间隔的导轨(7,8),它们彼此平行地布置,并且至少一个保持工件的工件夹具(9,10)(W1to W4)各自可以从传送位置(P1,P2)移动到工作位置(A1至A6),并且可以在切割器导轨(13)上移动两个圆盘切割器(17,18,21) 从第一工件(A1,A2,A5)的第一工作位置(A1,A2,A5)上布置在导轨(7,8)之间的工件(14,19),其工作在由第一工件夹具(9)保持的工件(W1, 到达由第二工件夹具(10)保持的工件(W2,W4)上工作的第二工作位置(A3,A4)。 根据本发明的装置允许以高精度的工件进行加工。
