Description
Affiliated technical field
The utility model relates to a kind of rotor internal combustion machine, affiliated technical field of internal combustion engines.
Background technique
At present, known rotary engine is mainly constructed by oval column chamber rotor of curve and epitrochanterian slipper piston and is formed, and epitrochanterian slipper piston does work in the elliptic cavity indoor sport.The tightness of this known rotary engine is bad, and is strict to tightness, and the power of its single chamber machine can not be too big, compression ratio is little, uses water cooling, is not suitable for diesel oil, and vibrations are bigger, thereby this internal-combustion engine requires high processing cost height to processing technique equipment.
Summary of the invention
For the power of the poor air-tightness that overcomes existing rotary engine, single chamber machine can not be too big, compression ratio is little, can not be suitable for diesel oil, and existence vibrations in theory, use water cooling, manufacturing requires the shortcoming harsh, that processing cost is high, the utility model provides a kind of rotary engine, and this rotary engine not only tightness is good, and single chamber acc power can be done very greatly, compression ratio can be done very greatly, can be applicable to diesel oil and gasoline, vibrations can be little of almost shockproof state, and cooling fully, and the manufacturing requirement is not harsh, and processing cost is low.
The technological scheme that its technical problem that solves the utility model adopts is: in the cylindroid chamber, rotor is that stationary axle is done the dead axle rotation with the cylindroid central shaft, and it is characterized in that: rotor is made up of radially stationary piston (11) of rotating around engine shaft (6) and the cylinder sleeve (9) that is enclosed within on the radial piston (11).Cylinder sleeve (9) end has the shared valve of intake and exhaust (18), the terminal opening and closing periodically with the to-and-fro motion of cylinder sleeve (9) of valve stem (18).On the valve seat (12) of cylinder sleeve (9) end two coaxial rolling bearings (15) that are symmetrical arranged and are parallel to each other are arranged, two rolling bearings (15) all embed standard ellipse rail slot (3), during rotor rotation, two rolling bearings (15) drive epitrochanterian cylinder sleeve (9) and do the elliptical orbit motion.Epitrochanterian cylinder and piston are that cruciformity or center symmetry radial radiation shape are provided with (for the sake of simplicity, a cylinder only draws in the Figure of description), radially static piston is arranged on the rotor, having on the piston can radially reciprocating cylinder sleeve, the cylinder sleeve end has two coaxial bearings to embed the standard ellipse rail slot and with the traction campaign of elliptical orbit, the distributing valve of cylinder sleeve end radially is provided with, and the radial extremity that the valve stem tail protrudes outwardly to coaxial bearings is in same radial position.Cylinder sleeve moves in a circle with rotor and does radially to-and-fro motion with the traction of standard ellipse track when rotor rotation, and the resultant motion of cylinder sleeve is the elliptical orbit motion.Valve is done the elliptic motion less than oval traction track of 1/2nd elliptic motions identical with traction track and 1/2nd minor axises on the cylinder sleeve, when valve is done 1/2nd elliptic motions identical with traction track, the valve stem tail is not squeezed, and valve keeps closing; When valve was done 1/2nd minor axises less than the elliptic motion of oval traction track, valve was squeezed, and valve is opened.See in a clockwise direction, valve is opened when piston is in 1/2nd minor axises less than the minor axis lower end of the ellipse of oval traction track, the cylinder volume minimum, along with cylinder sleeve clockwise rotates, cylinder volume increases valve and still stays open, cylinder suction, when movement cylinder during to the transverse left end point cylinder volume reach maximum, valve-closing, suction stroke is finished; Cylinder sleeve is rotated further valve and keeps closing, valve is subjected to oval traction track traction to move to this oval minor axis upper extreme point by 1/2nd long axis of ellipse left end points identical with oval traction track with cylinder sleeve, cylinder volume diminishes, and gas is compressed, and compression stroke is finished.The oil pump countercylinder oil spout that cylinder sleeve rotates with rotor coaxial when finishing compression stroke, the acting of fuel oil instantaneous burst countercylinder, rotary piston is shifted onto the right-hand member of this transverse tempestuously from the minor axis upper end of 1/2nd ellipses identical with oval traction track, gas does work to rotor, and expansion stroke is finished.When cylinder sleeve continues to move in the process of 1/2nd minor axises less than the lower extreme point of the minor axis of the ellipse of oval traction track, valve is opened volume of cylinder and is reduced, the cylinder exhaust, volume of cylinder reaches minimum exhaust stroke and finishes when cylinder sleeve reaches this oval lower extreme point, and this rotary engine is just rotated acting subsequently again and again.Be provided with the pipeline of fuel oil, lubricant oil machine oil in addition in the rotating shaft of rotor.Epitrochanterian cylinder sleeve rotates a week, oil pump to the cylinder fuel feeding once, for lubrication system, it is being provided with and tubule road that the end of source of lubrication conducting opens wide radially in the radial piston bar of rotor, and it makes flow of lubricant arrive the cylinder lubrication piston by the centrifugal force that rotates when rotor rotation; This machine adopts air-cooled, oval chamber one side arranged side by side be provided with one with the blower of rotor coaxial, fan rotates with the rotation of rotor and then to the cooling of the rotor air blast in the oval chamber, has also taken away waste gas simultaneously.
The beneficial effects of the utility model are, tightness is good, theoretical friction, modify-water is cold be air-cooled and cooling fully thorough, it is very big that the power of single chamber machine can be done, compression ratio can be done very greatly, can be applicable to diesel oil and gasoline, manufacturing is easy, processing cost is low.
