Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing.
Positive displacement birotor machine, including birotor air compressor machine, birotary engine according to the present invention etc..It is basic
Structure is all identical, and all by operating mechanism and control mechanism two parts, operating mechanism uses for completing scheduled work, control mechanism
In the motion association of control internal drive.
Now illustrate the basic structure of positive displacement birotor machine of the invention by taking birotary engine as an example.
As shown in Figure 1, being the basic structure (having shed the parts such as end cap) of birotary engine operating mechanism, there is one
There are the cylinder body 1 of cylindrical cavity, a main shaft 2, two groups of structures identical piston rotary A3 and piston rotary B4, piston rotary A3
It can be rotated around main shaft 2 with piston rotary B4, respectively there are one group of sector piston in piston rotary A3 and the one end piston rotary B4.Piston rotary
It is packed into cylinder body 1 after A3 is mutually nested with piston rotary B4 and 1 inner cavity of cylinder body is separated into four sector spaces 5 (Fig. 2), cylinder body 1
Both ends are equipped with end cap and just form four airtight cylinders.
When work, two groups of piston rotaries make periodical speed-changing rotation in cylinder body, when one group of piston rotary from low to fast when,
Another group of piston rotary is then from fast to slow, and vice versa.Two groups of piston rotaries are mutually chased so that the volume of four cylinders according to
It is secondary to change.Main shaft each rotation, the volume of each cylinder just change twice, just complete air-breathing, compression, expansion, exhaust one
A complete internal combustion engine circulation, each cylinder acting are primary.If being used as air compressor machine, main shaft each rotation, each cylinder
Just it is sequentially completed air-breathing twice to calm the anger, four cylinders complete eight working cycles altogether.As it can be seen that no matter being used as engine or pneumatics
Machine, working efficiency will all greatly promote.In addition, the operating phase of all cylinders is fixed, i.e., each cylinder is all identical
Position on complete identical impulse stroke, without controlling the valve mechanism of air inlet and exhaust, not only simplify structure, but also reduce energy
Consumption.
To air compressor machine, for hydraulic pump and hydraulic motor, the effect of control mechanism is to turn the uniform motion of main shaft input
Turn to the variable motion of two groups of pistons；It for the engine, then is based on the variable motion for generating two groups of piston rotaries converts
The uniform motion of axis and export.
Control mechanism of the invention is there are two types of design scheme, the first scheme is as shown in figure 3, control mechanism includes two groups of phases
Same control assembly, every group of control assembly control one group of piston rotary.Every group of control assembly all includes central gear 10, planet tooth
Wheel 11, crank throw 12, planet carrier 13, connecting rod 14 and synchronizing wheel 15.Central gear 10 connect with rack 16 and nibbles with planetary gear 11
It closes；Planet carrier 13 is connect with main shaft 2, uniformly distributed several axis holes on planet carrier 13；Crank throw 12 is packed into row after connecting with planetary gear 11
In the axis hole of carrier 13；12 one end of crank throw is connect with planetary gear 11, and the other end is connect with connecting rod 14；Synchronizing wheel 15 and piston rotary
A3 connection, the equally uniformly distributed several pin shafts of synchronizing wheel 15；14 both ends of connecting rod are provided with pin hole, and one end is connect with crank throw 12, one end and same
The pin shaft connection of step wheel 15.It is the basic structure of one group of control assembly shown in Fig. 4.
Second scheme is as shown in Figure 5.The connection side that the difference is that only planet carrier and synchronizing wheel of two schemes
The synchronizing wheel 15 of formula, scheme one is connect with piston rotary A3, and planet carrier 13 is connect with main shaft 2.The synchronizing wheel 15 of scheme two and master
Axis 2 connects, and planet carrier 13 is connect with piston rotary A3.The function of two schemes is identical, only need to be according to the structure cloth of machine
Office decides what to use.
By taking scheme one as an example, the working principle of control mechanism can be summarized as follows:
According to superposition principle of motion, the variable motion of piston rotary can be analyzed to a uniform motion and a speed change fortune
Dynamic, control mechanism is the motion association to control piston and main shaft around this principle.
Because planet carrier is connect with main shaft, and main shaft can only make at the uniform velocity rotation (motion of main shaft is discussed again below), so row
Carrier also can only at the uniform velocity rotate.At this point, crank throw is just with planetary gear rotation when revolution, revolution speed is equal to master
Axle speed, rotational velocity are then determined by central gear and planetary gear transmission ratio.The revolution of crank throw will push synchronous crop rotation
It at the uniform velocity rotates, the rotation of crank throw then pushes synchronous crop rotation speed-changing rotation, and two movement superpositions just form the periodical change of piston
Speed movement.As long as the motion association of piston and main shaft just determines therewith as it can be seen that the parameters of control mechanism have been determined.
The movement of main shaft is now discussed.If being used for air compressor machine or hydraulic pump, main shaft is input shaft, and input is at the uniform velocity naturally
Movement.If being used for engine, main shaft is output shaft, at this point, two groups of piston rotaries are driving links, output is one fast one slow
Variable motion, but two groups of piston rotaries all pass through crank link mechanism and connect again with main shaft, will generate mutual restriction to each other
Motion association so that main shaft can only be rotated with " average speed ", and this " average speed " is uniform motion.
Because the input terminal and output end of control mechanism are reversible, no matter piston when driving link or passive
Part, their movement all produce a kind of fixed correlation with main shaft, and operating mechanism is just worked normally.
In addition to the implementation, all to use equivalent transformation or equivalent replacement the invention also includes there is other implementation methods
The technical solution that mode is formed, should belong to the scope of protection of the invention.
