An apparatus for transforming a reciprocating movement of an axial reciprocatable motor (1) of piston-cylinder type like a pneumatic motor, a gas motor or a hydraulic motor to a constant rotating movement in one and the same direction of one or more output shafts (8, 9, 21) and comprising a first pulley (4) which is fixed mounted in relation to the cylinder part (2) of the reciprocatable axial motor (1) and a second pulley (6) which is mounted spaced from the axial motor (1), an endless drive belt (12) extending over the two pulleys (4, 6), and in which each pulley (4, 6) is formed with an output shaft (8, 9), and in which the piston rod end (3) of the reciprocatable motor (1) is connected to a yoke (13) which, with outer frame parts (14a, 14b) thereof, surround the two paths (12a, 12b) of the drive belt (12), and which comprises ratchet/pawl means (15, 17) which, at the active expelling stroke of the piston (3), provides a driving against one of the drive belt paths (12a) and which, at the retraction stroke of the piston (3), provides a driving against the second drive belt path (12b), whereby the drive belt (12), at both moving directions of the piston (3), will move in one and the same direction, and the shafts (8, 9) of the pulleys (4, 6) will rotate continuously and in one and the same direction, and in which the shaft (8, 9) of each of the pulleys (4, 6) carries a gear (10, 11), which gears (10, 11) are surrounded by an outer gear (20) having inner teeth, and having a shaft (21) providing a strongly gear reduced main drive shaft (21). |
