Definitions
- the invention relates to a device for control of a stage of pivoting or stalling vanes variable.
- EP-A-0 094 296 a particular device for setting a blade stage regulating the pressure drop in a secondary turbojet channel.
- the control ring is articulated to levers by means of rods and bent levers which control half of the blades so as to impose angular movements opposite two adjacent blades.
- coping mechanisms command which involve the use of an organ actuator such as a cylinder and a mechanism transmission composed of levers, connecting rods, etc.
- organ actuator such as a cylinder
- mechanism transmission composed of levers, connecting rods, etc.
- the characteristics of these transmissions are pretty varied and some allow orders not vane linear, that is to say that the rotation of the these are not proportional to the displacement of the actuator.
- the invention belongs to this kind of control devices and its essential advantage is that the transmission is particularly simple.
- control device is characterized in that the control ring is connected to the cam by an articulated transmission rod.
- the control device can also concern several stages of blades and several rings order at a time.
- it is then possible to have other cams articulated by pivoting around other first axes fixed to other control rings of other stages variable pitch vanes, the cams being connected between them by an articulated synchronization bar cams at identical positions relative to first fixed axes.
- there are other cams articulated in pivoting around other first axes fixed to others control rings for other stages of wedge blades variable the other cams being interconnected and with the crank turning by a bar of synchronization articulated to the other cams and to the crank in identical positions with respect to other first fixed axes and the second fixed axis.
- Figure 1 shows the entrance to a turbomachine with in particular a compressor section at low pressure 1 and a compressor section at high pressure 2. It is on this that the invention is established.
- Each compressor is above all composed of stages of fixed blades 3 and movable blades 4 which alternate, some attached to a stator 5 which surrounds the annular vein 6 for gas circulation and the others fixed to a rotor 7 delimiting the vein 6, and turning with him.
- a pin 17 fixed on the stator is established at cam 15 elbow to allow it to rotate, and its other arm 18 extends opposite the rod of transmission 12 and carries at its end another articulation 19 intended to support a bar of synchronization 20 perpendicular to the ring of control 10, that is to say arranged in the axial direction of the machine.
- Synchronization bar 20 is similarly articulated to other cams 15 assigned to the control of other stages of fixed blades 3 by transmissions similar to the one just described and which include in particular a control ring 10 for each of the floors.
- the only difference is what the other cams, denoted 15a, 15b, 15c, etc., have arms 16a, 16b or 16c, etc.
- the control mechanism unlike a solution previously adopted by the plaintiff, does not not a lever attached to the fixed axis 17 of the cam 15 considered first, and whose purpose is to rotate it to pull or push on control rods 12 through all the cams 15 and timing bar 20. Instead from that, we have a crank 21 rotating around a second fixed axis 26 parallel to the first axes fixed 17, 17a, 17b, 17c, etc., and a connecting rod 22 of which the ends are articulated, for the first 23 to the end of the crank 21, and for the second 24 to a part of the second arm 18 remote from the fixed axis 17.
- the angle ⁇ is therefore a sinusoidal function of the angle ⁇ .
- Crank 21 can be turned by the rod 27 of a jack 28 articulated at a fixed point 29, according to a usual design.
- angles ⁇ of rotation imposed on the levers 9 and the blades 3 are different for the various stages, and more specifically, they are proportional to lengths l, la, lb, lc, etc. of the arms 16 between the axis fixed 17 and articulation 14 of the transmission rod 12, that is to say that the rotation laws are all sinusoidal.
- cam 15 and 15a are not connected to synchronization bar 20 and its second arm 18 is replaced by arm 118 of another shape intended to receive a joint 123 uniting it with one end of a connecting rod 122 similar or similar to the connecting rod 22 and the other end of which is joined by a joint 124 to a protrusion 125 formed on a cam 115a moreover similar to cam 15a and located in the same place.
- the fixed axis 117a of articulation of the cam 115a is not an inert axis but a control axis dependent on the actuator member.
- the crank 21 of the previous embodiment is deleted and the cam 115a is a motor lever.
