The advantages of amount is light, easy to maintain.
Referring to Fig. 3-Fig. 7, it is connected with the electromotor of the special low rotation speed large torque clutch of the helicopter of the present embodiment and props up
Support system 16 is mainly consisted of：The right side of flange terminal pad 2 is connected with engine output shaft 1, and left side leads to clutch transfer panel 3
Bolt connection is crossed, it act as that the power of electromotor is delivered on clutch transfer panel 3.Pacify side by side on clutch transfer panel 3
Two spring bearings 4 are filled, its internal ring coordinates with clutch transfer panel 3, its outer shroud and friction plate and get rid of block system 17 and coordinate, to
Guarantee clutch transfer panel 3 and friction plate in clutch separation state and get rid of freely rotating for block system 17.
It is main with the friction plate and centrifugal block for clutch use system 17 of the special low rotation speed large torque clutch of the helicopter of the present embodiment
Constitute as follows：Inner attrition piece 5 and outside friction disc 6 are staggered, totally three layers；Get rid of one end axle of block rocking arm 8 and be connected in clutch transfer panel 3
On, can rotate around rocker shaft 21, the other end is connected and is stuck in 7 on friction plate gland with block 9 is got rid of, and when electromotor works, utilizes
Leverage will be got rid of the centrifugal force that block 9 produces and be converted into the pressure that is pressed on friction plate gland 7, so as to compress each layer friction plate,
Inner attrition piece 5 is driven to rotate；Back-moving spring 10 between clutch transfer panel 3 and friction plate gland 7, stalling or during the slow-speed of revolution
Reduce each friction pole sheet pressure, prevent it from engaging；The inner side spline of inner attrition piece 5 is arranged on the external splines of serves 11, is passed through
Spline transmitting torque；The inner side of serves 11 is arranged in electromotor connection and support system 16 on the outer shroud of spring bearing 4.
With the main composition of flexible clutch system 18 of the special low rotation speed large torque clutch of the helicopter of the present embodiment such as
Under：Input shaft end 12 and output shaft end 13 respectively with the fit of intermediate elastomeric 14, using the spy of intermediate elastomeric elastically deformable
Point is compensated while transmitting torque to axial direction, radial direction and axial deviation.Input shaft end 12 is connected with serves, defeated
Go out shaft end 13 to be connected with helicopter reducer gear shaft 15.
Referring to Fig. 3-Fig. 7, the clutch course of work of the present embodiment is as follows：
Before engine start, using the elastic anchorage force 24 of back-moving spring 10 by clutch transfer panel 3 and friction plate gland 7
Strut, no pressure between inner attrition piece 5 and outside friction disc 6, thus zerofriction force.Referring to Fig. 8, the inner side of inner attrition piece 5 is machined with
Internal spline 20, serves 11 are machined with external splines 19, and herein to be slidably matched, i.e., spline can be in circumferential transmission for spline fitted
Inner attrition piece 5 is also allowed to carry out axially-movable along serves 11 while moment of torsion.
After engine start, engine output shaft 1 drives the flange terminal pad 2 connected with it to rotate together, at the same time
Clutch transfer panel 3 and the synchronous axial system of flange terminal pad 2；Get rid of block rocking arm 8 and get rid of block 9 and centrifugation is produced due to obtaining angular velocity
Power 22, in the case where centrifugal force 22 is acted on, gets rid of block rocking arm 8 and gets rid of block 9 and move out around rocker shaft 21, by the thick stick for getting rid of block rocking arm 8
Bar effect is amplified, and gets rid of pressure 23 that block rocking arm 8 produces to friction plate friction top 7 more than getting rid of block rocking arm 8 and get rid of the centrifugation that block 9 is produced
Power 22；Referring to Fig. 9, the left end of block rocking arm 8 is got rid of for cam mechanism, move out with block rocking arm 8 is got rid of, itself and friction plate friction top 7
Contact point away from rocker shaft 21 distance increase, cause friction plate friction top 7 to move to clutch transfer panel 3.
Referring to Figure 10, when engine speed is relatively low, the centrifugal force 22 for getting rid of block rocking arm 8 and getting rid of the generation of block 9 is less, because of centrifugal force
22 thrusts 23 for causing are less than the elastic anchorage force 24 of back-moving spring 10, therefore simultaneously malcompression between friction plate, now rotate
Part be flange terminal pad 2, clutch transfer panel 3.Referring to 11, outside friction discs at different levels are stirred in the rotation of clutch transfer panel 3
6th, block rocking arm 8 is got rid of, therefore outside friction disc 6 is also at rotary state with block rocking arm 8 is got rid of.But due to malcompression between friction plate,
Inner attrition piece 5 is not rotated together with outside friction disc 6, thus serves 11, the flexible clutch system 18 being attached thereto
Do not rotate.
Engine speed is incrementally increased, and the centrifugal force 22 for getting rid of block rocking arm 8 and getting rid of the generation of block 9 is also incrementally increased, because of centrifugal force
22 thrusts 23 for causing sometime are exceeding the elastic anchorage force 24 of back-moving spring 10, make inner attrition piece 5 and outside friction disc 6
Between gradually compress, under the drive of frictional force, inner attrition piece 5 starts to be rotated with outside friction disc 6.At the same time, by spline
It is also synchronous with inner attrition piece 5 with serves 11, flexible clutch system 18, the helicopter gear shaft 15 of the connection of inner attrition piece 5
Rotate.But before engine speed reaches design speed, because centrifugal force 22 is not enough, get rid of block rocking arm 8 and get rid of the centrifugal force pair of block 9
The pressure 23 that friction plate gland 7 is caused is not enough, thus inner attrition piece 5 is with the rotation of outside friction disc 6 and asynchronous, now they
Between friction type be sliding friction；Engine speed is reached after design speed, and inner attrition piece 5 is completely combined with outside friction disc 6,
The two synchronous axial system, now friction type is static friction, now serves 11, flexible clutch system 18, helicopter gear
Axle 15 and the synchronous axial system of engine output shaft 1, reach design work state.Again due to inner attrition piece 5 and external friction during this
The combination of piece 6 be progressively, it is progressive, thus drive shaft system will not be impacted, cohesive process is more steady.
It is similar with cohesive process after transmission process is completed：The rotating speed of engine output shaft 1 is gradually reduced, and is attached thereto
Flange terminal pad 2, clutch transfer panel 3, outside friction disc 6, the rotating speed that gets rid of block rocking arm 8, get rid of block 9 also decline, and get rid of block rocking arm 8 and get rid of
The centrifugal force 22 that block 9 is produced reduces, and gets rid of block rocking arm 8 and the pressure 23 of friction plate gland 7 is reduced, in the elasticity of back-moving spring 10
Under support force 24 is acted on, friction plate gland 7 progressively move to the direction away from inner attrition piece 5, inner attrition piece 5 and outside friction disc 6 it
Between pressure reduce, serves 11, flexible clutch system 18, the helicopter gear shaft 15 being connected with inner attrition piece 5 is outside
Inner attrition piece 5 is driven to depart from outside friction disc 6 in the presence of portion's damping, their rotating speed is gradually decrease to stalling.
In the present invention, the difference with reference to rotating speed is required in order to adapt to different operating modes, the rigidity of scalable back-moving spring 10.
When the rigidity of back-moving spring 10 is larger, overcome the centrifugal force needed for its elastic anchorage force 24 larger, thus the rotating speed of engine output shaft 1
It is larger, so when design combine rotating speed it is larger；In contrast, when the rigidity of back-moving spring 10 is less, design combine rotating speed also compared with
It is little.
