Abstract:
A belt tensioning apparatus, comprising a tensioning wheel (1) and a wheel shaft (2) provided on the axis of the tensioning wheel (1), and further comprising a fixing support (3). The tensioning wheel (1) is rotatable with respect to the wheel shaft (2); the wheel shaft (2) extends out of one side of the tensioning wheel (1) and is provided with a radial threaded hole; the fixing support is provided with an adjusting screw (4) and a guide slot; the wheel shaft (2) is inserted into the guide slot; the adjusting screw is threadedly connected to the threaded hole; and as the adjusting screw (4) is threaded in or out, the wheel shaft (2) and the tensioning wheel (1) are integrally slidable along the guide slot.
