Abstract

A rotor-type engine with reciprocating piston features that the V-shaped slot formed on rotor can change the straight-line reciprocating movement of piston to rotation, the piston, connecting rod and slide block do straight-line movement parallel to output shaft under the action of guide rod, and the output shaft rotates by one turn when a 4-stroke cycle is finished. Its advantages are simple structure and high output power.

Description

The reciprocating piston type rotor motor

Technical field reciprocating piston type rotor motor belongs to technical field of internal combustion engines.

Background technique reciprocating piston crank engine is by bent axle, and connecting rod is transformed into rotatablely moving of bent axle with the linear reciprocating motion of piston, in one week of crankshaft rotating of conventional engine, finishes compression, work done, exhaust, an air-breathing work cycle.

The distribution device of reciprocating piston crank engine, be by valve, break bar; rocking arm; compositions such as pitman arm shaft and support, mainly contain three kinds, i.e. gear transmission chain transmission and toothed belt transmission to the kind of drive of cam; general transmission from the bent axle to the camshaft only needs a pair of timing gear, can install breast wheel additional in case of necessity by bent axle.Chain transmission can satisfy because the distribution transmission requirement of bent axle and camshaft distance motor far away, but structure is complicated, and it is inconvenient to adjust, and its usability depends on the workmanship of chain to a great extent.Synchronous cog belt is a kind of kind of drive that extensively adopts in recent years, and it can be used for replacing chain transmission, adopts the transmission of profile of tooth bar, can reduce noise, reduces architecture quality.Select from " newly organized automobile answer " first volume of motor that People's Transportation Press goes out.

Summary of the invention reciprocating piston type rotor motor is to have replaced bent axle in the reciprocating piston type crank engine by engine rotor, the linear reciprocating motion of piston directly is transformed into the structure that rotatablely moves of engine rotor.It is by rotor, piston, and connecting rod, slide block, guide rod is formed.The gas distribution structure of reciprocating piston type rotary engine, mainly by cam, rocking arm, valve is formed.

Description of drawings

(1) rotor of reciprocating piston type rotor motor (as figure one) it be relatively and the groove that connects by two V font mouths, be evenly distributed on interior (outward) circumference of rotor, slide block slides in V font groove, impels rotor to rotate.

(2) existing is that example illustrates its working principle with four cylinder reciprocating piston type rotor motors, and the reciprocating piston type rotary engine is slided in the chute of V font rotor by rotor.Piston, connecting rod, slide block under the guide rod effect, does reciprocating linear motion, and rotor rotates under the effect of slide block.(as figure two) when piston A carried out expansion space stroke, the piston B corresponding with A was simultaneously descending air-breathing, and the C piston adjacent with AB begins exhaust, and the D piston begins compression.When piston D carried out expansion space stroke, adjacent A piston began exhaust, and piston C is simultaneously descending air-breathing.The B piston begins compression.When piston B carried out expansion space stroke, piston A was simultaneously descending air-breathing, and the D piston begins exhaust, and the C piston begins compression.When piston C carried out expansion space stroke, piston D was simultaneously descending air-breathing, and the B piston begins exhaust, and the A piston begins compression and finishes a four-stroke work cycle.Output shaft rotates a circle.Piston will be finished work done, and exhaust is air-breathing, compress a work cycle.

(3) gas distribution structure of reciprocating piston type rotor motor, (as figure three) 1. output shaft 2. cam 3. rocking arm 4. valve 5. piston 6. push rod 7. body 8. slide block 9. runner 10. guide rod rotor is by cam, rocking arm, valve are formed gas distribution structure.Cam is installed on the output shaft, and output shaft rotating band moving cam rotation is opened rocking arm, drives valve opening simultaneously, finish air-breathing, exhaust process.Have four tops on the cam of reciprocating piston type rotor motor, output shaft whenever rotates a circle, and the work of two valves can be controlled in each top of cam, the work of eight valves will be controlled in four tops of cam, finish exhaust, and will be air-breathing, compression, work cycle of work done.

Claims

The structural type of reciprocating piston type rotor motor claim 1. rotor.Guide rod, slide block, runner, slide block and runner match with concave groove, and the slide block runner is done straight line motion in concave groove, and the rotor that has concave groove that makes rotates, and rotatablely move thereby linear reciprocating motion converted to.

The gas distribution structure of the conventional engine that reciprocating piston type rotor motor claim 2. is made up of output shaft, camshaft, rocking arm, exhaust valve intake valve etc.
