Operation principle：
（1）, assume outer rotor 2 remain static or outer rotor 2 rotating speed less than internal rotor 1 rotating speed, due to isolation arm 6 make
The fluid isolation on the both sides of annular working chamber 51, so when internal rotor 1 drives oscillating tooth assembly 3 to turn clockwise in annular working chamber 51
When dynamic, the oscillating tooth 32 in the left side of isolation arm 6 is tapered into the cavity for isolating arm 6, so being formed in this arc working chamber
Hydraulic oil, hydraulic oil gives isolation 6 one clockwise thrusts of arm, the equally oscillating tooth 32 on the right side of isolation arm 6 and the chamber for isolating arm 6
Body becomes larger, so forming negative pressure oil in this arc working chamber, negative pressure oil gives isolation 6 one clockwise pulling force of arm.
Because the form of two isolation arms 6 is identical, so two isolation arms 6 are subject to same dextrorotation in annular working cavity 51
Turn power.
Constraining for annular geo-stationary orbit 9 is received in the track of the radial motion in annular working chamber 51 of oscillating tooth 32, is embedded into annular
Track bearing 36 in geo-stationary orbit 9 drives oscillating tooth arm 31 to be rotated along the shape of annular geo-stationary orbit 9 by synchronizing shaft 33, works as work
Tooth 32 go to isolation arm 6 residing for arc to position when, oscillating tooth 32 in the presence of the indent arc section 91 of annular geo-stationary orbit 9 inwardly
The center of circle of rotor 1 is moved radially, and its oscillating tooth arm 31 and oscillating tooth 32 are completely embedded into oscillating tooth groove 4 so that internal rotor 1 is in annular working
Cavity interior energy is continuously rotated.
As shown in figure 3, because annular geo-stationary orbit 9 makes the angle that oscillating tooth starts interior shifting in radial directions be in isolation arm
30 ° of 6 right side, annular geo-stationary orbit 9 make oscillating tooth start the outer angle moved in radial directions be in 30 ° of the left side of isolation arm 6,
As shown in figure 1, when oscillating tooth C starts to return to oscillating tooth groove 4, oscillating tooth B has been fully penetrated into working chamber 51 and has been formed isolation
State, so the two ends of isolation arm N and isolation arm M are isolated by oscillating tooth A, B, C all the time, so isolation arm N and isolation arm M are in work
Continuously stress in chamber.
Open when electromagnetic switch valve 12, when electromagnetic exposure valve 13 is closed, hydraulic oil passes sequentially through oil leak passage 18, height and is pressed into
Mouth 17, high-pressure outlet 15, pressure duct 14, electromagnetic switch valve 12 enter piston groove 10, and hydraulic oil promotes front side board 8 to be moved back by
It is dynamic, while the power being moved rearwards by is delivered on internal rotor 1 and back side panel 7, because internal rotor 1 and front side board 8 can be in axial directions
Moved freely on direction so that the seal clearance between internal rotor 1 and back side panel 7, between internal rotor 1 and front side board 8 diminishes,
So that the oil pressure of annular working chamber 51 becomes big, the power that oscillating tooth 32 is applied on isolation arm 6 becomes big；Equally, when electromagnetic switch valve 12
When closing, electromagnetic exposure valve 13 are opened, the hydraulic oil in piston groove 10 passes sequentially through leakage magnetic valve 13, leakage pipeline 16 and reveals
To in common pressure chamber 52 so that the pressure reduction of the inner high voltage of piston groove 10 oil so that between internal rotor 1 and back side panel 7, internal rotor 1
And the seal clearance between front side board 8 becomes big, the power that oscillating tooth 32 is applied on isolation arm 6 diminishes.
（2）, assume that oscillating tooth 32 is F to two total active forces of isolation arm 6 by fluid, active force radius is R, then interior turn
Son 1 act on outer rotor 2 torque T1 be：T1=F*R；
（3）, torque output and speed change analysis and calculation specifications：
If internal rotor 1 is T1 to the turning moment that outer rotor 2 is provided, the rotating speed of internal rotor 1 is n1, according in rotative power release
The rotary power P1 that rotor 1 is applied on outer rotor 2 is：
P1=T1*n1/9550 1.,
If the extrernal resistance torque of outer rotor 2 is T2, rotating speed is n2, then the rotary power P2 of outer rotor 2 is；
P2=T2*n2/9550 2.,
According to law of conservation of energy P2=P1, the output speed for 1., 2. releasing outer rotor 2 by formula is：
N2=n1*T1/T2 3.,
3. be can be seen that by formula under conditions of the power P 1 that internal rotor 1 is acted on outer rotor 2 is certain, the rotating speed of outer rotor 2
Outer load resistance square T2 with its outer rotor is inversely proportional, and the outer load resistance square T2 of outer rotor 2 is big, then the rotating speed of outer rotor 2 is slow,
The outer load resistance square T2 of outer rotor 2 is small, then the rotating speed of outer rotor 2 is fast, when the moment of resistance T2 of outer rotor 2 is carried equal to internal rotor 1
During the rotation torque T1 of confession, the synchronization of outer rotor 2 and internal rotor 1 thus achieves continuous stepless velocity transformation.
