Definitions
- the invention relates to an adjusting device for rudders of a missile, the rudders of servomotors over Adjustable thrust spindles and the servomotors in one arranged in the missile tail carrier housing are.
- Such an actuator is in the DE 43 35 785 A1 described.
- the servomotors are there provided with their own housings and on the carrier housing swinging. This structure demands one comparatively large installation space.
- Another control device for rudder one Steerable projectile is in DE 34 41 533 C2 described.
- a bearing arrangement for the swiveling rudder blade a steerable missile in particular a means Propellant gas pressure of the closable floor known from DE 34 41 534 A1.
- the object of the invention is to provide an actuator type mentioned with a particularly compact structure to propose.
- the above object is achieved in that the Stators of the motors directly in the carrier housing are arranged and that the push spindle in one Internal thread of the motor shaft engages.
- the stators of the servomotors in the carrier housing are built in, there is no need for own Motor housing, which saves space and one Weight reduction means. Even in a cramped one Missile tail can use two actuators with parallel Axes can be installed side by side. So it's not necessary, the servomotors are staggered in the longitudinal direction Arrange rear, which would increase the overall length.
- the an actuator is used to adjust a pair of oars.
- the other servomotor is used to adjust the other Oars.
- a small overall length is also possible because of the Engage thrust spindles in the internal thread of the motor shafts.
- the compact design is with a weight reduction connected.
- the extremely small and light Actuator is particularly suitable for a a propellant-projectile projectile (mortar projectile), has the rudder.
- the carrier housing is like this designed, that it is arranged in the rear area, the Rear area of the projectile against radial forces, in particular gayak forces.
- the carrier housing is like this designed, that it is arranged in the rear area, the Rear area of the projectile against radial forces, in particular gayak forces.
- One is sufficient reduced wall thickness of the rear area, resulting in a Weight saving and an installation space with enlarged Inner diameter is allowed.
- the inner ring and the outer ring support one the motor shaft bearing bearing at one Launch acceleration of the missile in the carrier housing from.
- the carrier housing Disc is preferably one in the carrier housing Disc provided.
- a projectile that can be fired with a propellant (Mortar level) carries a pair of oars in the rear area 1 Oars 2 and a pair of oars with oars 3.
- Oars 2,3 can be folded out about axes A (see Fig. 4 with Fig. 1) and by means of an adjusting device around rudder axes B swiveling.
- the actuating device has a carrier housing 4, which is used in the rear area 1.
- the dimensionally stable carrier housing 4 supports the rear area 1 radially from the longitudinal axis F of the floor and thereby increases Radial pressure forces are created, so that the Wall thickness of the rear area 1 where it from Support housing 4 is supported to be smaller than usual can. This increases the usable space inside the Rear area 1.
- the motors 5,6 are side by side (cf. Fig. 3,4). Their motor shafts run parallel to one another. Both motors 5,6 have the same structure and the same Way connected to the assigned pair of oars. in the For simplification, the following is just one engine and described its coupling to its rudder pair. For the same applies to other motors.
- the motor is brushless and houseless. His stator 7 is inserted directly into the carrier housing 4, for example glued. Its rotor 8 sits on the Motor shaft 9.
- the motor shaft 9 is at both ends by means of Carrier housing 4 roller bearings 10 used, for example angular contact ball bearings.
- roller bearings 10 used, for example angular contact ball bearings.
- the bearing there is a disk 11 in the rear-side roller bearing 10 intended.
- the outer ring 12 of the Rolling bearing 10 on.
- the Disc 11 a step 40 with regard to the rolling bearing 10 precisely defined game between inner ring 13 and Outer ring 12 on.
- the inner ring 13 of the roller bearing 10 on the disc 11 on which the outer ring 12 stands.
- the axial force acting on the roller bearing 10 limited so that the rolling bearing 10 does not destroy becomes.
- the inner ring 13 of the deformed elastically by the launch acceleration Bearing back from the disc 11 so that the inner ring 13th free is.
- the Motor shaft 9 has an internal thread 14 into which an axial Movable push spindle 15 secured against twisting engages with an external thread 16.
- an engagement nut 18 with one attached to the axis B of the one oar pair Driving lever 19 is coupled.
- the Adjustment position is by means of a counter screw 20 definable.
- the specified actuating device is small and comparatively easy. Few moving parts are sufficient for a smooth-running gear train.
- an arm 21 is attached to the an actuator 22 of a linear potentiometer 23 attacks.
- the linear potentiometer 23 is connected to one in the room 24 arranged control electronics connected.
- the Linear potentiometer 23 is in a recess 25 (cf. 3) the carrier housing 4 is arranged.
- About the Linear potentiometer 23 becomes the actual position of the control electronics of the respective oar pair reported.
- Linear potentiometers can also take other measures Detection of the actual position of the rudder may be provided.
