Motor shown in the drawings, two rotating shafts are housed in the cylinder body 11, one of them and axis rigid joint be concentric shafts 1, rotatably be sleeved on the axis for hollow shaft 2(referring to Fig. 2), can be main shaft with any, another is an auxiliary spindle, that is: can be that concentric shafts 1 is main shaft, and hollow shaft 2 is auxiliary spindle (as Fig. 1); Also can be that hollow shaft 2 is main shaft, concentric shafts 1 be secondary rotor (as Fig. 3).One group of piston 12 that matches with cylinder body 11 is respectively arranged in the major and minor rotating shaft, and every group of number of pistons is even number, is generally 2 or 4 (as Figure 12), and two groups of number of pistons equate and interleaved, constitute main rotor and secondary rotor thus.Two rotating shafts have two kinds to connect scheme with the differential control mechanism:
1. see shown in Figure 1, dial 8 is directly installed on the main shaft, and positioning wheel 5 is to link indirectly by auxiliary axis 3 and gear train and auxiliary spindle, i.e. positioning wheel 5 and gear 4 rigid joint that are installed in simultaneously on the auxiliary axis 3, and the gear 10 that is meshed with gear 4 is installed on the auxiliary spindle.
2. see shown in Figure 3, positioning wheel 5 directly is assemblied on the auxiliary spindle, and dial 8 is to link indirectly by auxiliary axis 3 and gear train and main shaft, i.e. dial 8 and gear 10 rigid joint that are installed in simultaneously on the auxiliary axis 3, and the gear 4 that is meshed with gear 10 is installed on the main shaft.This scheme only is applicable to that every group of piston is that 4 or 4 adopt when above.When auxiliary axis 3 during with two parts of being installed also rigid joint, it rotates continuously with main rotor, also can be as output shaft.
In fact gear train mainly is drive connection one end that is serially connected in dial 8 and positioning wheel 5 formations as inverter unit, and gear train has the gear stage of odd level, and its minimalist program is made up of two gears.
When dial 8(or positioning wheel 5) with main rotor (or secondary rotor) when directly connecting, its teeth groove number (or crown number) should equate with the quantity of every group of piston; There are following relation in the teeth groove number of dial and the crown number of positioning wheel:
Crown number=teeth groove number * gear train velocity ratio
Be 2-4 at the teeth groove number generally, the crown number is to select in the individual scope of 4-6.
The velocity variations of the curve shape of dial teeth groove during according to secondary rotor motion requires to determine, preferably uses cycloid, also can be involute, hyperbola, helix, or one section circular arc line.When dial 8 rotation, the crown of positioning wheel contacts with camber line on the dial circumference, and slide relative.For making the positioning wheel crown reliably along dial circular arc line incision teeth groove, utilize a secondary spring 9, generally be to adopt coiled springs, the one end forward connected with main shaft or the parts that are installed on the main shaft, on the other end and the auxiliary spindle or the parts that are installed on the auxiliary spindle link.
For reducing the surface friction drag of positioning wheel crown on dial, cylindricality ball 17(such as Figure 13,14 are housed on the positioning wheel increment); Perhaps load onto cylindricality ball 18(such as Figure 15) on dial teeth groove notch both sides.
Secondary rotor is under the effect of differential control mechanism, and its piston produces some and stays positions temporarily when rotate in cylinder body, at half spaced apart temporarily when on the cylinder body of the front side of position or both sides, front and back spark plug 16(being housed as petrol engine); Oil thrower (as diesel engine time) perhaps is housed.Be respectively equipped with suction port 15 and relief opening 14 near second half stays the both sides of position temporarily the cylinder body, angle γ between the two has following relation with dial teeth groove angle α and positioning wheel two adjacent teeth point to dial central angle β (see figure 5):
γ=2 alpha+betas (when dial and main shaft are directly installed)
γ=(2 alpha+beta)/n (when positioning wheel and auxiliary spindle were directly installed, n was the gear train velocity ratio)
When as pneumatic motor, all are provided with relief opening 14 and suction port 15(such as Figure 16 on the cylinder body of both sides in the position temporarily respectively).
Suffered reaction force of secondary rotor and the pressure that produces on the positioning wheel crown thus are provided with check device when reducing the main rotor work done.This is to utilize to be installed in the outer ratchet 13 of cylinder body, stretches in the cylinder body from relief opening 14, and be ratchet with secondary rotary piston, act on the side of piston outer rim; Also can on auxiliary spindle, adorn a ratchet, with the click-fit of relative set.
Concentric shafts 1 except with hollow shaft 2 from homonymy stretches out, can also also stretch out from opposite side, auxiliary axis 3 corresponding lengthenings simultaneously are installed in the cylinder body both sides respectively with two transmission systems of differential control mechanism.
In addition, a plurality of motors can also be connected in series by main shaft, utilize power done time official post output more steady.
Working principle of the present utility model following (is example with the gasoline engine):
Referring to accompanying drawing 1-11, four pistons are divided into I, II, III, four chambers of IV in cylinder, are arranged in order (is counterclockwise as figure) and rotate with piston by the rotor sense of rotation.In the working procedure, the main rotor continuous motion, secondary rotor is done variable motion when temporarily staying between the position transposition.Fig. 4,6,8,10 is for rotor rotates the cyclic process that half cycle is finished, and the corresponding relation of dial and positioning wheel is shown in Fig. 5,7,9,11.
If Fig. 4 is an initial position in the cyclic process, in the process of Fig. 4-Fig. 6, the igniting work done of I chamber, the exhaust of II chamber, the III chamber is air-breathing, and the IV constant pressure contracts.The main rotor of rotation drives the dial rotation continuously, by Fig. 5 to Fig. 7 position, and tightens coiled springs; Under the spring force effect, the crown of positioning wheel is pressed against on the dial, and along the circular arc line relative movement, secondary rotor suspends in the temporary position of staying.
In the process of Fig. 6-Figure 10, the exhaust of I chamber, the II chamber is air-breathing, and the III constant pressure contracts, the igniting work done of IV chamber.By dial circular arc line incision teeth groove, secondary rotor is promoted to become by the expansive force of combustion gas and quickens rotation the positioning wheel crown by spring force, and this power acts on main rotor through crown to the promotion of teeth groove side simultaneously, forward promotes the main rotor motion; In the stage of positioning wheel crown relative movement to the dial circular arc line, the motion of secondary rotor is controlled, and slows down under the III constant pressure contracts the effect of resistance simultaneously, stays the position temporarily until another, main rotor has also rotated same angle, and whole system " answer " is to initial position.Begin next circulation then.
When every group rotor piston is four, in cylinder, form 8 working rooms (structure as shown in figure 14), by counterclockwise being arranged as I, II, III, IV, V, VI, VII, VIII, the working state I of each chamber is identical with V, II is identical with VI, and III is identical with VII, and IV is identical with VIII.Working principle as hereinbefore.
The utility model is directly exported with the main rotor of continuous rotation, and it is little that the differential control mechanism bears power, and power consumption is also little, the less processing and assembling of being convenient to of the parts of differential control mechanism.But a cyclic process work done twice, rotating a circle has the work done process at least four times, exports more steady.Because main rotor is at the volley by working room's work done of correspondence, therefore can alleviate " firing " phenomenon.
