Abstract

The utility model discloses a peanut shell rotary engine which comprises an engine shell, a rotor, an output shaft, air cylinders, pistons and safety rails, wherein the output shaft integrally rotates with the rotor; four air cylinders are uniformly arranged on the rotor; the pistons move in the air cylinders; the rotor, the air cylinders and the pistons are integrally sealed in the engine shell; the shape of the engine shell is an oval like a peanut shell; at the compression stroke end and the exhaust stroke, the ends of the engine shell are narrow; at the work stroke end and the suction stroke end, the ends of the engine shell are wide; the outer ends of the pistons slide along the inner wall of the engine shell during rotation; the outer ends of the pistons are guided to slide from the narrow part of the engine shell to the wide part of the engine shell in the work stroke; one of the four air cylinders is always in the work stroke, action is relayed, and the rotor is driven to continuously rotate.

Description

Peanut shell rotary engine

Technical field

The utility model relates to technical field of engines, especially relies on the engine with piston-type rotor of motor body inwall control engine stroke and rotation---peanut shell rotary engine.

Background technique

The maximum motor of application is all that piston promotes by connecting rod the Reciprocating engine that bent axle rotates now, but during the course because Crankshaft motion has lost part energy, cause people finding the mode that a kind of direct output rotatablely moves always, but unique rotary polygonal piston engine of only having of carrying out practical application, it has removed connecting rod, bent axle and gas distribution structure, realize air-breathing with the eccentric motion of a triangular rotor, compression, acting, exhaust, the moving element that it is few and stably output make it possess the advantage in volume and speed, but wearing and tearing and lubrication problem and low speed performance are that it is difficult to the defect of avoiding at present, make rotary polygonal piston engine be difficult to promote.

Summary of the invention

Be convenient to promote in order to make the mode that directly output rotatablely moves, overcome wearing and tearing, lubrication problem and the performance of raising low speed of rotary polygonal piston engine, the utility model proposes a kind of advantage of combination Reciprocating engine, rely on engine with piston-type rotor---the peanut shell rotary engine of motor body inwall control engine stroke and rotation.

The utility model solves the technological scheme that its technical problem adopts: peanut shell rotary engine, comprise engine housing, rotor, output shaft, cylinder, piston, insurance track, output shaft and rotor unitary rotation, four cylinders are on average set on rotor, piston moves in cylinder, rotor and cylinder, piston integral sealing is in engine housing, the ellipse of the similar peanut shell-shaped of engine housing, narrow in compression stroke and exhaust stroke end, wide at working stroke and suction stroke end, slide along engine housing inwall in piston outer end in rotation, slide to wide part from the narrow part of engine housing at working stroke in guiding piston outer end, four cylinders have one all the time in working stroke, relay action, rotor driven continues to rotate.Cylinder bottom arranges air-vent, relief opening and suction port are set on engine housing, compression and the acting stage of air-vent in rotation is friction sealed by cylinder bottom and shell, and air-vent carries out exhaust and suction stroke through relief opening and suction port in the time turning to exhaust and expiratory phase.Spark plug and oil nozzle are arranged on compression stroke terminal position on shell, light a fire and oil spout by air-vent, in the time adopting compression ignite mode, oil nozzle are only set.Wherein suction stroke is the centrifugal action by piston, for preventing that the frictional force of piston and cylinder is because the accident such as lubricated can not drive the situation of suction stroke, an insurance track is set on engine housing, piston can not be driven under centrifugal action and guide piston action air-breathing in the situation that.For reducing the friction of piston outer end and engine housing inwall, ball can be set in piston outer end in addition, ball can require to add or omit according to engine design.

The beneficial effects of the utility model are, make to adopt the motor of this structure more simple in structure than simple Reciprocating engine, and motor moving element only needs a rotor and four pistons generally, has saved distribution and connecting rod, crankshaft structure; Owing to having adopted ripe piston movement form, avoid sealing, wearing and tearing, the lubrication problem of rotary polygonal piston engine; Because rely on the outer end motion of engine housing guiding piston, form lever, the relay of four cylinders action simultaneously makes the output shaft acting four times of circling, and has strengthened the low speed torsion of rotor.The utility model combines the advantage of Reciprocating engine and rotary polygonal piston engine, has removed their shortcoming simultaneously, and manufacture cost is declined, and improves performance simultaneously, makes the motor mode that directly output rotatablely moves be convenient to promote.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1-Fig. 3 is embodiment's Facad structure of the present utility model and running schematic diagram.

Being encoded in accompanying drawing: 01 is engine housing, and 02 is rotor, and 03 is output shaft, and 04 is cylinder, and 05 is piston, and 06 is ball, and 07 is air-vent, and 08 is relief opening, and 09 is suction port, and 10 is spark plug, and 11 is oil nozzle, 12 is insurance track.

Embodiment

As shown in Figure 1-Figure 3, embodiment's Facad structure of the present utility model and running schematic diagram are shown, wherein engine housing 01 entirety forms an ellipse, the shape of a similar peanut shell, narrow in compression stroke and exhaust stroke end, wide at working stroke and suction stroke end, the interior canned rotor 02 of engine housing 01, rotor 02 rotates together with output shaft 03, four cylinders 04 are on average set on rotor 02, piston 05 is in the interior motion of cylinder 04, ball 06 is arranged on piston 05 outer end, for reducing the friction of piston 05 outer end and engine housing 01 inwall, air-vent 07 is arranged on cylinder 04 bottom sidewall, relief opening 08 and suction port 09 are arranged on engine housing 01, in the time that forwarding relief opening 08 position to, air-vent 07 starts exhaust, in the time that forwarding suction port 09 position to, air-vent 07 starts air inlet, spark plug 10 and oil nozzle 11 are arranged on compression stroke terminal position, in the time that forwarding spark plug 10 and oil nozzle 11 position to, air-vent 07 works, in the time adopting compression ignite mode, cancel spark plug 10.Insurance track 12 is arranged on ball 06 inner side on engine housing 01 sidewall, prevents that piston 05 from can not enter intake stroke under centrifugal action, and guiding piston 05 moves.

Working principle of the present utility model is for rotating when rotor 02, ball 06 is subject to the restriction of engine housing 01 to promote the interior gas of piston 05 continuous compression cylinder 04, in the time that cylinder 04 turns to spark plug 10 and oil nozzle 11 position, it is engine housing 01 the narrowest position, the spark plug 10 of oil nozzle 11 is worked, the interior mixed gas of some gas cylinder 04, enter working stroke, the mixed gas of lighting promotes piston 05 and outwards moves, slide along engine housing 01 the narrowest position to width position by ball 06, drive whole rotor 02 and on four cylinders 04 rotate, in the time that a cylinder carries out working stroke, other three cylinders carry out respectively exhaust, air inlet, compression stroke, four cylinder relay action rotor drivens 02 continue to rotate, make output shaft 03 keep continuing acting output.
