An axial-to-rotary motor includes a double acting pneumatic motor of piston-cylinder type. An endless drive belt extends over a first pulley, which is fixed mounted in relation to the pneumatic motor, and over a second pulley mounted spaced from the piston rod. The motor further includes one or more output shafts arranged for being continuously rotated. The piston rod end of the pneumatic axial motor is connected to a yoke which, with the outer frames thereof, encloses the two paths of the drive belt, and which encloses a ratchet device which provides a drive force against one of the drive belt paths at the active expelling stroke of the piston rod. The yoke also provides a drive force against the second drive belt path at the retraction stroke of the piston rod, whereby the drive belt will move in one and the same direction at both piston movement directions. |
