ABSTRACT:
A structure which is of the utmost simplicity, rigidity and reliability has a transmission arrangement (1) for converting the rotary movement of a motor into a linear movement of a driven body (21) along a curved path. It is of a configuration that includes a stationarily arranged spindle (2) which is curved to correspond to the shape of the curved path, and at least one thread counterpart portion (4) which is engaged with the thread of the curved spindle and which is rotatable about the spindle, and by virtue of that rotary movement, displaceable in the longitudinal direction of the spindle. The stator (14) of the motor is connected to the driven body and is mounted non-rotatably and longitudinally displaceably with respect to the curved spindle, and the rotor (5, 15) of the motor is non-rotatably connected to the thread counterpart portion.
