Abstract

The utility model relates to a spring drive speed differential rotary engine; wherein, transmission springs (5 and 7) are connected between pistons (4 and 6) and a main shaft (2) and a ratchet (13) and a damping section (14) are arranged in an air cylinder (1). Pistons (4 and 6) are connected on the main shaft (2) with cross longitudinal sections and an ejecting block (8) and a spring (8-1) are positioned in a radial hole of each piston (4 and 6). A ratchet (13) is disposed in a venthole (10) in an air cylinder (1) and a damping section (14) is provided in an air suction hole (12). The ratchet (13) and the damping section (14) are arranged concavely on an internal wall of the air cylinder (1) and a curved surface of the damping section (14) gradually transits to an internal circle surface of the air cylinder (1) in large slope. The engine uses the springs as a power transmission mechanism, so that the structure is simple, a speed differential rotor and a drive device are lightened and the inertial impact force is reduced, so as to reach higher rotate speed.

Description

Spring transmission differential rotary engine

Technical field

The utility model relates to a kind of rotary internal combustion differential engine.

Background technique

In the ring cylinder of differential rotary engine, have with around two groups of pistons of a rotation, produce relative movement between these two groups of pistons and form the variation of swept volume.Can satisfy the mechanism of two groups of piston relative movement nothing more than gear, connecting rod, cam, universal joint mechanism and elliptic gear mechanism etc.But these transfer mechanism structure more complicated, the big quality of volume are also big, and inertia that is produced and impact force are also bigger, inaccessible always higher rotation speed.Ka Erci (kauertz) motor is a kind of common differential speed type motor, two pairs of fan-shaped pistons are housed in its circular cylinder body, pair of pistons is to be connected to a direction running and with pto with uniform angular velocity, another links to each other with a hollow shaft to piston, and hollow shaft and pto be concentric does differential motion.Do variable speed running and produces inertial force owing to stepped piston, make parts such as driving mechanism middle gear and connecting rod be subjected to stronger impact force, noise is aggravated.Therefore the rotating speed of motor is very limited.In addition, these motors are because structure is limit, and lubrication problem is puzzlement people's a difficult problem always, always can not find effective and feasible lubricated approach.

The content of model utility

The technical problems to be solved in the utility model is to overcome the deficiency described in the background technique, and provide a kind of assembling simple in structure, easy, main is little by the caused impact force of power transmission mechanism mass inertial force, and can reach the differential rotor motor of higher rotation speed.

Technological improvement of the present utility model is: the transmission spring is connected between piston and the main shaft, also is provided with ratchet and damping section in cylinder.

Further technological improvement of the present utility model is: piston is the X-shaped formula with the longitudinal section and is connected on the main shaft, is provided with jacking block and spring in the radial hole of each piston.Ratchet is located at the exhaust port place in the cylinder block, and the damping section is located at the suction port place.On cylinder, also be provided with the IGNITION CONTROL mechanism that constitutes by spark control lever, contact, nut and stage clip.

Compare with background technique, the good effect that the utility model produced is: as the power transmission mechanism between main shaft and the piston, it is simple in structure, volume is little with spring for this motor, in light weight.Because of this transfer mechanism only is a torque spring, absorb stepped piston with the elasticity of spring and make the inertial force that variable-speed motion produces, the quality of its differential rotor and transmission device can alleviate, and has also just alleviated inertial impact force.Because torsion transmission spring has the function of absorption and balanced inertial impact force,, can steadily turn round reliably again so this motor can improve rotating speed.

Embodiment

As shown in Figure 1 and Figure 2, be provided with the

piston

4,6 that two groups of side direction are X type cross-distribution in cylinder 1, and be coupling on main shaft 2, main shaft 2 is constrained on the cylinder 1 by bearing 3.

Torque spring

5,7 as power delivery is enclosed within outside the main shaft 2, and wherein, the two ends of spring 5 are connected with piston 4 with main shaft 2 respectively, and the two ends of spring 7 are connected with piston 6 with main shaft 2 respectively, and two

springs

5,7 are 90 ° of angles on main shaft 2 fixes.In the radial hole of each piston 4a, 4b and 6a, 6b, all have jacking block 8 and spring 8-1.Be provided with ratchet 13 at cylinder 1 inner peripheral surface near near exhaust port 10, near designed again near the suction port 12 its curved surface with big gradient gradually to the damping section 14 of cylinder 1 inner peripheral surface transition.Ratchet 13 and damping section 14 equal indents are in the inner peripheral surface of cylinder 1.Also be provided with the IGNITION CONTROL mechanism that forms by spark control lever 9, contact 9-1, nut 9-2 and stage clip 9-3 on the cylinder 1.Wherein spark control lever 9 passes stage clip 9-3.Also be provided with breast door 11 on the cylinder 1.

If the moment of torsion that makes main shaft 2

drive

4,6

o'clock springs

5,7 of piston is negative, the moment of torsion of

spring

5,7 was for just when

piston

4,6 drove main shafts 2, and when engine start, main shaft 2

drives piston

4,6 respectively by

spring

5,7 and rotates, and this moment, two

springs

5,7 were negative torque.When piston 4a arrived damping section 14, damping section 14 was given 8 one resistances of jacking block, it is underspeeded or stops operating.Jacking block 8 among the piston 6a then enters ratchet 13 places, and jacking block 8 offsets with spark control lever 9 under the effect of spring 9-3, and it is contacted with contact 9-1 and exports an ignition control signal, carries out igniting by ignition mechanism.Because

spring

5,7 parameters unanimities differ 90 ° again and fix on main shaft 2, so piston 4 obtains bigger negative torque than piston 6, and increase with the rotation of main shaft 2.After negative torque makes piston 4 overcome the resistance of damping section 14, quicken again to rotate at the effect lower piston 4 of spring 5 negative torques, its piston 4b closes suction port and enters compression stroke.And piston 6a enters 14 decelerations of damping section or stops operating under the effect of spring 7 negative torques and compression gas-pressure, and this moment, piston 6b stopped at the igniter front side.When piston 4b goes to first tooth of ratchet 13 with inertia, jacking block 8 is a jack-up spark control lever 9, push against contact 9-1, piston 4a also reaches the igniter rear side, igniter is promptly realized igniting, between piston 6b, 4a, carry out detonation, make piston 6 overcome damping force and accelerated motion, make spring 7 become positive moment of torsion again and drive main shaft 2 rotations.Piston 4 is stopped operating by the combustion-gas pressure effect and by jacking block 8 torque reaction is passed to cylinder 1, be expansion space stroke this moment between piston 6a and the 4a, being exhaust stroke between piston 6b and the 4b, is suction stroke between piston 4b and the 6a, is compression stroke between piston 6a and the 4a.Next piston 4a and 6a enter the zone of combustion igniting, and motor carries out the normal operation of revolution four-ignition.
