At first will be described in detail the concrete structure of carry-out part 1 below.

An output shaft 3 is by side plate 4a supporting, and side plate 4a belongs to the part of rotor part 2 middle shells 4, and rotor part 2 is in freely rotates and bearing state.Drive wheel 5 is installed in the both sides of output shaft 3, and the axle head of output shaft 3 stretches out side plate 4a, 4.A d.c. motor 9 is connected on the one axle head.Motor 9 can be connected on this output shaft, can break away from from this output shaft again, and this will be according to the rotational frequency of output shaft 3, adopt one in the dress control gear realize its connection, disengaging.The effect of this control gear is exactly when the rotational frequency of output shaft 3 is scheduled to rotational frequency above one, output shaft 3 and motor 9 is disconnected, and when its rotational frequency is lower than this preset limit, make it to connect.

And then be described in detail the concrete structure of rotor part 2.

With reference to Fig. 1, rotor part comprises rotor body 6(6a, 6b, 6c), three rotor bodys become around 120 ° of centers that are distributed in output shaft 3.Through each rotor body 6(6a, 6b, 6c) the rotating shaft center, be provided with a supporting axle 7, this supporting axle 7 is provided with drive wheel free to rotate 8,8,8.Drive wheel 5 engagements on these drive wheels and the carry-out part 1.Drive wheel 8 adopts spirals to connect (not shown)s and is installed in rotor 61,63(Fig. 3,4 on the rotor body 6) the side on.

Motor 9 and a battery 10 link, and label 11 has shown a dc switch.

Each supporting axle 7 all is a positioning shaft, and shown in Fig. 3～5, three

rotors

61,62,63 are and are installed on the supporting axle 7 free to rotately, and the bearing 12 through being provided with free rotary state has vertically constituted rotor body 6.The cross section of each rotor 61～63 all is the H shape.Portion is relatively set with

rotation part

13a and 13b, 13c and 13d and 13e and 13f within it, in two relative rotation parts, each all plays balanced action, and each rotation part 13a～13f has a center of rotation that is made of pin 14, and pin 14 is in the outer of rotor 61～63.The center that pin 14 departs from rotation part 13a～13f is provided with, and promptly is in this eccentric position from moving part, and when this rotor rotated, the part of each rotation part then can be protruding from the outer rim of rotor 61～63 like this.As shown in Figure 1, rotation part 13a～13f is provided with like this, each rotation part all with identical distance be arranged on supporting axle 7 around.

Crank body

15,15 is installed on the supporting axle 7 through bearing 12a, and they are positioned at the side of rotor 61～63 on each supporting axle 7.Crank body 15 has prevented in rotation process because the continuing of the state of protruding rotor 61～63 outer rims of action of centrifugal force rotation part 13a～13f.For this reason, this crank body clamps among the groove 153a that is in centre bearing body 153 crank web up and down 151,152 that is the state that freely swings on the centrepin 16 shown in Fig. 5～7.The inner of each crank web 151,152 is all made carinate, and the section of this supporting mass further groove 153a bottom also is carinate.The outer end of crank web 151,152 is made slotted hole 151a, 152a along the vertical direction up and down.With reference to Fig. 4, the slotted hole 151a on top is passed by a connecting pin 17a, and this connecting pin is with the rotor 61(62 of movable state from left side neighbour) extend.A connecting pin 17b passes the slotted hole 152a of bottom, and this connecting pin is with the rotor 62(63 of movable state from right neighbour) extend.Therefore each crank body 15 all is that rotation by rotor 61～63 drives.Since each go up or the bottom drift angle of the inner angle of lower crank plate 151,152 or supporting mass 153 further groove 153a very big, more than or the hunting range of lower crank plate very little.

With reference to Fig. 2, belt 19 places between the side and generator 18 of output shaft 3, generator 18 and battery 10 electric connections, and the electric power that generator 18 is produced by the rotation of output shaft 3 is used for to battery 10 chargings with compensates electric consumption.

Belt 21 places between the axle 20a of the opposite side of output shaft 3 and hydraulic pump 20, and the driving force that produces from hydraulic pump 20 is sent to hydraulic engine 23 through a solenoid valve 22, arrives generator 24 then.

To narrate working procedure below based on rotor of the present invention.The rotational power of motor 9 is sent to rotor 61～63 from the

drive wheel

5,8 of output shaft 3 through rotor body 6a shown in Figure 1,6b, 6c.When rotor 61～63 rotated in each rotor body, rotation part 13a～13f was around pin 14 eccentric rotary.Because the action of centrifugal force that rotor 61～63 high speed rotating are produced, the part of rotation part 13a～13f is then stretched out (see figure 1) from the outer rim of rotor 61～63, is tending towards keeping this state that stretches out simultaneously.Yet when crank body 15 rotated continuously, balance had therebetween been broken in crank web 151,152 swings up and down.Therefore the state that stretches out of rotation part 13a～13f no longer can be kept continuously.As a result, each rotor body 6a～6c is all owing to appearance and the housing 4 interior vacuum states of rotation part 13a～13f are quickened.This acceleration is sent to output shaft 3 thus.When the rotational frequency of this output shaft surpassed a preset frequency, a control gear moved, and limits the interlock process of motor 9.Its result produces a kind of ouput force greater than input power at output shaft 3 places.When the rotational frequency of output shaft 3 was lower than characteristic frequency, the driving force of motor 9 then was sent to output shaft 3 once more.When output shaft 3 rotated, the generator 24,18 that is shown among Fig. 2 began to produce power.

Principle of the present invention can be used for generator, and the rotor of engine, hydraulic motor etc. for example, is applied to a hydraulic motor with rotor of the present invention, then adopts little Input Forces can produce big power output.

The vacuum state of keeping in the housing 4 is necessary, like this can accelerating rotor body 6, and the high speed rotating of rotor block 6, the shape of this balanced body is not limited to the shape of above-mentioned rotation part.
