Connection, it is coaxial that second housing 9 and the first shell 1 with annulus nested mode connect guarantee.Second housing 9 include endless screw electric motor 10,
Retarder 11, endless screw electric motor 10 are fixed by screws on second housing 9, and 10 outer wall of endless screw electric motor is harmonious with second housing 9, snail
Bar motor 10 is connected by keyway with retarder 11.11 outer wall of retarder is harmonious with second housing 9, and retarder 11 and motor 10 are logical
It crosses keyway mode to be connected, retarder 11 is connected with worm screw 12 by keyway mode, and retarder 11 and the first shell 1 pass through pin side
Formula is fixed.Worm screw 12 is connect by key with retarder 11, and worm screw 12 is connect by worm and gear gear with worm gear 14.
As shown in figure 3, worm screw 12 of the present invention is outside 11 side of retarder setting ball bearing 13,13 outer wall of ball bearing and first
Shell 1 is harmonious, and inner wall is harmonious with worm screw 12, and ball bearing 13 is stuck between the first shell 1 and worm screw 12 by bearing shoulder；Ball bearing 13
When for bearing turbine and worm transmission, the radial force that worm screw 12 is subject to achievees the purpose that radial limit worm screw 12.Worm screw 12 is another
Side (i.e. end) is arranged to diagonal contact ball bearing 15, pairs of 15 outer wall of angular contact ball bearing simultaneously with the first shell 1 and end cap
16 are harmonious, and pairs of 15 inner wall of angular contact ball bearing is harmonious with worm screw 12, and pairs of angular contact ball bearing 15 is stuck in end by bearing shoulder
Between lid 16 and worm screw 12.End cap 16 is connected by screw with the first shell 1, and end cap 16 passes through outside annulus nested mode and first
Shell 1 connects, and ensures that pairs of angular contact ball bearing 15 and worm screw 12 are coaxial in this way.Pairs of angular contact ball bearing 15 is for worm screw 12
When axial retention, i.e. balance turbine and worm transmission, the axial force on worm screw is acted on, to reach the mesh of axial limiting worm screw 12
's.Worm gear 14 is connected by worm and gear gear with worm screw 12.First shell 1 and second housing 9 and end cap 16 are between any two
It is fixed by screw mode, the first shell 1 is guaranteed with annulus nested mode coaxial with second housing 9 and end cap 16.The
One shell, 1 inner wall is harmonious with ball bearing 13 and the outer wall of pairs of angular contact ball bearing 15, and passes through bearing shoulder stop.
Ball bearing 13 of the invention is 61800 deep groove ball bearings, and using the benefit of the specific device: a) this is standard component,
Buying is easy, cheap；B) it generates heat small, larger radial force can be born.Pairs of angular contact ball bearing 15 is that 7003DB carries on the back back formula
Angular contact bearing 15, using the benefit of the specific device: a) this is standard component, and buying is easy, cheap；B) generate heat small, energy
Also biggish bidirectional axial force can be born while bearing larger radial force.
The course of work of the invention is: endless screw electric motor 10 is slowed down by gear reduction unit 11, and the driving rotation of worm screw 12 drives
Worm gear 14, worm gear 14 and transmission shaft 2 are connected by key, and keep the first radome fairing 3, the first blade motor 4, the first blade 5, second whole
The 6, second blade motor 7 of stream cover, the synchronous inclination of the second blade 8.When need to turn a fixed angle θ when, setting turbine and worm pass
Dynamic ratio is i, then makes 12 rotational angle of worm screw be i θ to control system to 10 input control signal of endless screw electric motor.
The present apparatus mainly solves following problems:
A) synchronism verted.It is mechanical synchronization that turbine and worm mode, which is verted, is inclined relative to controlling two by electric signal
For transfering from one department to another system, there is high synchronism and reliability.
B) stability verted.The driving source of entire turbine and worm is single motor, the anti-interference ability of motor signal
By force.
C) angle locking verted.Turbine and worm has the function of reverse self-locking, i.e., can only drive turbine by worm screw, and whirlpool
Wheel cannot drive worm screw.This just mechanically solves the orientation problem of tilt angle, i.e., only needs to motor input signal, will
Rotor shaft rotates to suitable angle, without worrying that the stress in rotor shaft reversely drives turbine and worm, influences to vert
Angle.
D) tilt angle position limitation protection.The tilt angle of tilting rotor only between 0 ° -90 °, does not allow generally to go beyond the scope.This
The position limitation protection mode of scheme is simple, reliably.It is lower than 0 ° i.e. on turbine and the turbo tooth higher than 90 ° stamps locking pin.If
Motor departing from control, i.e., tilt angle lower than 0 ° or higher than 90 ° when still working, then the locking pin on turbine can prevent snail
Bar continues to rotate, and achievees the purpose that limit tilt angle.
This rotor reclining device is mainly by a micromotor, and a gear reduction unit, one group of worm couple forms, micro-
Type motor and retarder are fixed on the machine body, and when work, entire mechanism is slowed down by two kinds of devices of retarder and worm and wormwheel, are made
Worm gear obtains the slow-speed of revolution and large torque, guarantees steady reliable when rotor verts, and worm and gear has extremely strong self-locking function,
It can guarantee the position precision that rotor turns to.Sleeve mechanism motion transmission line is short, high-efficient, compact-sized.The rotor verts machine
The successful application of structure will make the rotor aircraft that verts than helicopter possess farther voyage, the higher speed of a ship or plane, and compare fixed-wing
The higher mobility of aircraft and lower operation cost.And mechanism components itself are few, are mostly standard component, production early period system
It is short to make the period, and later period dismounting is easy to maintain, and sleeve mechanism input cost is low, good in economic efficiency.
