Patent attributes
The invention relates to a device for locking at least one belt (10) at predetermined belt tension, which belt (10) is arranged at a machine arrangement (1) with belt drive. The machine arrangement comprises a stand (3) having legs (2) placed on a base (4). At least one driving pulley (5) and at least one driven pulley (6) are aligned relative to each other. The legs (2) being articulately attached to at least one of the stand (3) or the base (4), and at least two of the legs (2) comprises longitudinally adjustable tension legs (20), which each comprises a first tension leg part (21) having a wedge box (30) arranged to receive a wedge (31) having a grooved surface (32) and a second tension leg part (22) having a grooved surface (23) directed towards said wedge box (30). The first (21) and second (22) tension leg parts are adapted to lock in relation to each other by cooperation between the grooved surface (32) of the wedge (31) and the grooved surface (23) of the second tension leg part (22) when the wedge (31) is adapted to wedge in wedge box (30).
