  • the belt tension rollers are rotatably supported, of which in Fig. 14, the belt tensioner pulley 1 12 in the upper region in association with the belt 104 can be seen.
  • the motor drive shaft 66 passing through the roller drive motor 65 in the region of its central opening 71 is rotatably mounted on the bottom 164 via a bearing 166. In the axial end region extending beyond the bottom 164 or the bearing 166, the motor shaft 66 carries the belt drive pulley 70.
  • Each of the two oscillation mass units 74, 76 is constructed with an oscillation mass housing 168 constructed separately from the carrier 52 and fixed thereto, for example, by screwing or welding.
  • Each Oszillationsmassengekoruse 168 includes a fixed to the carrier 52 peripheral wall 170 and two provided at the axial ends of the peripheral wall 170, lid-like bottoms 172, 174. These may be formed separately from the peripheral wall 170 and fixed thereto, for example by screwing. Alternatively, one of the bottoms 172, 174 could be integrally formed with the peripheral wall 170.
