| 摘要 |
The invention concerns a tensioning device (1) for driving a traction mechanism, comprising a base part (2) and a pivoting arm (5) connected by a pivot bearing (6). A twisting spring (11) enables the swivelling roller (8) placed at the free end of the pivoting arm (5) on the belt (10) to be supported by friction-type connection. A motion damping system for adjusting the movement of the pivoting arm (5) includes a friction ring (15). |
