Description

Rotary combustion engine

The utility model belongs to the internal-combustion piston engine field, relates to the rotary combustion engine that slidercrank mechanism is housed in a kind of rotor.

Traditional quartastroke engine, the cam mechanism that the gear drive that main slidercrank mechanism, gear and the cylinder block of being made up of piston, connecting rod, bent axle and cylinder block formed and cam, air inlet and exhaust valve, push rod and cylinder block are formed constitutes, cam and push rod are used for opening and closing suction valve and outlet valve, in order to guarantee two weeks of bent axle revolution, the inlet and outlet valve each open and close once, gear ratio has been installed is 1: 2 gear transmission between bent axle and camshaft.When combustion gas promoted reciprocating motion of the pistons, air inlet and exhaust valve opened and closed regularly, was the thermal power transfer of combustion gas the mechanical energy that bent axle rotates just.Traditional internal combustion (IC) engine cylinder block can not be moved, finish the four-stroke action, required distribution device complexity, in addition parts are many, make volume big and benzene is heavy, cause vibration big, cam, push rod are easy to wear, and it is big that air inlet and exhaust valve opens and closes noise, because intake efficiency is low, make fuel-oil atmozation not good, influenced the power and the rotating speed of motor.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and provides a kind of simple in structure, do not need cam mechanism, adopt rotator type slidercrank mechanism and gear rotation and revolution driving mechanism, finish the four-stroke action, improve mechanical energy, reduce the rotary combustion engine of vibration and noise.

The utility model is achieved by the following technical solution: rotary combustion engine comprises gas distribution system, ignition system and slidercrank mechanism, gear drive, parallel being symmetricly set in the rotor of slidercrank mechanism that its difference is made up of piston, bent axle, cylinder block, connecting rod; Rotor and the gear drive of being made up of end cap gear, crankshaft gear engagement are arranged in stator and the end cap; The stator periphery is provided with into, relief opening and spark-plug hole; End cap is fixed on the stator bi-side.

Another technical solution: the gear on the end cap maintains static, and the gear on the bent axle is done the planet running around the end cap gear, and end cap gear and crankshaft gear gear ratio are 2: 1.

In addition, end cap is provided with one-way valve.

The utility model is compared with prior art simple in structure, and in addition parts reduce, and fault is few, maintenance is easy, and cost is low, volume is little, in light weight, reduces vibration and noise, and supercharging automatically, raising intake efficiency and power per liter, the rotating speed and the power of raising motor.

Below in conjunction with drawings and Examples the utility model is described in further detail the explanation: consult Fig. 1, shown in Figure 2, rotary combustion engine mainly is made of gas distribution system, ignition system and slidercrank mechanism, gear drive, rotor, stator, end cap.Stator (10) is garden tubular structure (consulting Fig. 7 to shown in Figure 9), casting, its periphery is provided with suction port (1), relief opening (2), Carburetor directly is connected with suction port (1), the intake efficiency height, can improve the rotating speed and the power of motor, also be provided with spark-plug hole (5) on its periphery; Rotor (6) is housed in the stator (10), and rotor (6) is garden column construction (consulting Figure 10 to shown in Figure 12), and there is rotor of output shaft axle (14) at two ends; Parallel A, B or a plurality of cylinder block (9) of being symmetrically installed with in the rotor (6) is provided with the slidercrank mechanism that is made of piston (7), bent axle (8), connecting rod (11) in the cylinder block; Bearing (15) is equipped with at bent axle (8) two ends, gear (4) is equipped with in one or both ends, mesh with end cap gear (3), and do rotation and revolution, because the gear (3) on the end cap (13) maintains static, the gear (4) on the bent axle (8) can be done the planet running around end cap gear (3), and end cap gear (3) is 2: 1 with crankshaft gear (4) gear ratio, be that rotor (6) circles, crankshaft gear (4) two weeks of rotation.Stator (10) bi-side connect firmly two end caps (13) with screw (16), end cap (13) is garden shape disk-like structure (consulting Figure 13, shown in Figure 14), there are rotor of output shaft axle hole (19) and end cap bearing hole (20) in the center, is used for the installation and the output of rotor of output shaft axle (14).The outer fixed gear (3) that is equipped with of end-cover axle bearing (21) meshes with crankshaft gear (4).End cap (13) inboard is provided with concave station rank and seal ring (17); Can be provided with one-way valve (22), (23) on the end cap (13), open breather check valve (22) when gas distribution system gas and enter circulation in the stator (10), and open outgassing nonreturn valve (23) and enter firing chamber (12), form automatic supercharging, fuel gas buring promotes piston (7) motion, therefore can improve intake efficiency and power per liter.

Working principle of the present utility model; Consult Fig. 3 to shown in Figure 6, with the twin-tub quartastroke engine is example, the cylinder of A position (9) is first cylinder among the figure, with this cylinder explanation working principle, 1 is suction port among the figure, 2 is relief opening, because the gear ratio of the gear (4) on end cap gear (3) and the bent axle (8) is 2: 1, according to kinematical theory as can be known rotor (6) circle certainly, crankshaft gear (4) two weeks of rotation, public affairs circle, when bent axle (8) forwarded Fig. 4 A position to by Fig. 3 A position, piston (7) forwarded lower dead center to by top dead center, and be intake stroke this moment, bent axle (8) rotates to 360 of Fig. 5 when spending by 180 degree of Fig. 4, be equivalent to crankshaft gear (4) and revolve three-sixth turn, equal to go up public turnback at end cap gear (3) and finish compression stroke, this moment, the A cylinder was aimed at spark-plug hole (5), by the plug ignition work done, bent axle (8) is finished expansion space stroke by 540 degree that 360 degree rotate to Fig. 6.Bent axle (8) continues to rotate in inertia finishes exhaust stroke when Fig. 3 A position 720 is spent, rotor this moment (6) revolves three-sixth turn, and crankshaft gear (4) is gone up the public three-sixth turn of fixed gear (3) around end cap (13), and rotation 720 degree are got back to Fig. 3 A position.In sum, the every three-sixth turn of rotor (6), piston (7) in the rotor (6) is finished suction, pressure, quick-fried, four stroke work cycle of row respectively, like this, rotor (6) circles certainly, gear (4) on the bent axle (8) is spent around gear (3) rotation 720 on the end cap (13), gets back to 0 degree position, this shows that the working stroke of rotary combustion engine and the cam mechanism working stroke of four-stroke reciprocating internal combustion are identical.In like manner, the utility model can be widely used in twin-tub, four cylinders, eight cylinder IC engines and petrol engine and diesel engine.
