Servomotor, especially for controlling regulating slide valves

The invention relates to one operating at low speed Servomotor, in which the processes of starting, " Stopping or reversing the direction of rotation with practically no inertia to be carried out "

This servomotor is especially designed for operating control slides provided, however, this is only an example Type of application.

Ifis, various systems for controlling Eegelachiebern have already become known, but they are all expensive and space-consuming and have various disadvantages. This applies, for ₀ example, for the classic system while applying * (jcomprimierter air as driving means for, with costly arrangements are required for forming the compressed air Similarly, for this Zweöfc are:. Previously used hydraulic motors heavy and space-claiming and require an arrangement whose pump works continuously * regardless of whether the slide is operated or not operated,

Furthermore, most known systems make use of one sensitive and expensive comparator required

The erfindungsgeiräße servomotor is now connected to any of these disadvantages and allows a very considerable moment of force on the control rod, an S _c Hiebers exert only a small volume under stress.

In certain embodiments according to the invention, this results furthermore the advantage of using an electric motor, i. 'an engine, which can easily be forgotten with energy.

The servomotor according to the invention is now characterized in that it has, in combination, an actual motor of a known or unknown type, which applies a greater force torque to a shaft, whereby the shaft is given a swinging motion and a clutch is in front of ^^ e ^ n, which is capable of converting the oscillating movement of the motor envexity into an ijrexiue movement, this coupling having a power output shaft, one cam of which has one or more parts, and a power supply ring gear is designed in one piece with the shaft This ring gear is coaxial with the shaft and centered on the cam, the components cooperate by means of rollers which are arranged between the flat surfaces of the cam and the ring gear and means for moving these components either in one or more holes direction are provided so that a wedging z \ regard can be made to the cam and the ring gear, whereby a rotary movement is applied to the power output shaft, sooald äieseloe

This servo motor differs from the well-known, among other things Systems to the effect that the movement of the actual motor directs the clutch without reduction, and thus without Loss of energy is transmitted. ■;

Between the ring gear and the three parts of the cam 11a there are three hollow hollows 13 in which the axes 14 are located, and this arrangement is between two washers 15. There are elastic bearings on the axes, such as Z ₀ B.

• Bead-shaped connectors 16 made of rubber centered at each outer end of the lugs 13 so as to compensate for errors in alignment «
It goes without saying that the lumps 13 do not have any in their middle position

. Exercise effect and rest smoothly due to their design against the parts 11a of the shaft 12, and that the oscillating movements of the ring gear 11, regardless of the direction in which they take place, not ^ are transmitted to the shaft 12, which remains in the rest position. This position corresponds to the neutral one. Position of the * coupling "

It can also be seen that it is sufficient to use the rollers 13 to arrange with an angle by means of a suitable device, danjix the movements of the ring gear 11 only in one Iirehrrichtung are transmitted to the shaft 12, with the Drehoeweegungen have no effect on shaft 12 in the other direction,

The shifting and locking of the rollers 13 at one of the outer ends of their positional arrangement can be controlled by any known arrangement. In the embodiment shown here, these arrangements have spiral springs 17 which are hinged to the aciise 18, which are made in one piece with a ring 19, i) the springs 17 have one of their ends in engagement with one of the washers 15 integrally m ± t ^ oo the ichQsn are executed iiollen 13, ün the other end are never * iiOdern integrally connected with a disc 20 °, the concen- ^ is arranged symmetrical to the shaft 12 "a displacement of the Sohei-

One can of course also use any other suitable tax system for aas move the disk 10 use »

Ea thus shows that the clutch according to the invention is automatic has a blocking and automatically releasing effect and the processes of coupling and uncoupling take place immediately and without a moment of inertia.

A coupling can of course also be used as part of the air finding apply in which-the tease of the shaft 12 is circular wherein the parts lla of the nod described corresponding cavities in this case χτ. Inside the ring gear U is provided siddo

The modified embodiment shown in FIG. 6 enables an adaptation of the coupling system to a tl; gate, whose V / elle not with a swinging motion, but with a rotary motion is driven. '

The middle ring gear 11 of part 1 is in this case with an arm 15 provided - and cut away in a practically right-angled At 26 of the same there is a crank 27 in

As stated further then, the servomotor according to the invention only takes up a very small volume while simultaneously exerting large impact moments Hydraulic motors that are in use for this purpose (iewicnt have at least 250 kg and allow only a % force of 700 kg to be exerted on the control rods of .slides.
