Abstract
The invention relates to a stepping mechanism for rotary motions with a driven switching wheel (9) which comprises at least one wheel-side stop (10), with an escapement mechanism having at least one pawl (12) which cooperates with said wheel-side stop, and with an actuating device (3, 17) for the pawl. Pursuant to the invention, a miniaturizable stepping mechanism is provided which is of a simple design and which permits reliable positioning of the switching wheel into preselected individual rotational positions. According to the invention, this is achieved in that the escapement mechanism of the stepping mechanism comprises a brake (20) displaceable under the action of force, with a run-up edge (21) lying in the region of each pawl (12) on to which the wheel-side stop (10) runs up before striking the pawl (12) to thereby displace the brake. Preferably, the brake and the pawls are arranged on a rocker (20, 13) for each, these being pivotable about a common rotary shaft (14) not lying in the axis of rotation (A) of the stepping mechanism. The stepping mechanism can be used for the control (i.e. steering) of missiles. To this end the switching wheel is preferably connected with a rotary nozzle body (1) which, via a thrust nozzle (8), delivers a propellant jet approximately in a radial direction.
