Abstract
The utility model relates to a rotary piston structure used for various piston type engines. The utility model is provided with a bevel guide slot on a piston, and a guide pin matched with the guide slot is arranged on a cylinder. A spindle and two slide wheels inlaid in a flywheel are in tight connection. The utility model has the advantages of little space occupation, stable rotation, simple manufacture and fabrication and low production cost.
Description
The utility model relates to a kind of rotary piston structure, is used for various piston type motors.
Conventional engines is by cylinder, piston, crank, connecting rod and join, oil supply mechanism of qi structure forms, pass to crank by the energy that produces after the detonation of firing chamber by the connecting rod that connects piston, this kind motor, because crank mechanism itself just takies very big space, make motor under the situation that guarantees original power, can't reduce volume; Moreover cylinder arrangement is not compact, and it is short to be easy to generate angular force, makes rotary speed unstabilization fixed, and crank, Machining of Connecting Rod complexity, and performance requirement is very high, so cost of production is higher.
The purpose of this utility model be to provide a kind of take up room little, simple in structure, stabilization of speed, easy processing, lower-cost a kind of rotary piston structure.
The purpose of this utility model is achieved in that
The utility model includes cylinder, piston, it is characterized in that: piston places in the cylinder, on the piston face wall, have the inclined-plane guiding groove, the guide finger that matches with guiding groove is housed on the cylinder, rotary main shaft is equipped with at piston one end middle part, and the rotary main shaft the other end closely is connected with two movable pulleies that are installed in the flywheel middle part.
Can have guiding groove on the cylinder inner wall, on the piston guide finger that matches with guiding groove can be housed.
Piston and rotary main shaft can be cast as one.
On the rotary main shaft a plurality of pistons can be housed.
The piston middle spindle place can have a hole, and two movable pulleies are equipped with in the bottom, hole, matches with rotary main shaft in the hole, and rotary main shaft one end is connected with flywheel, and the other end places between two movable pulleies, and closely connects with it.
The utility model can be adorned a plurality of pistons on the cylinder main shaft, configuration corresponding mechanism (comprising distribution, oily mechanism), be set to a plurality of firing chambers, reduced invalid taking up room, and it is, make rotation more stable, and simple in structure owing on same main shaft, do work, processing and fabricating is easy, has reduced cost of production effectively.
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a half section structural representation of the present utility model;
Fig. 2 looks sectional view for master of the present utility model;
Fig. 3 is another kind of example structure figure of the present utility model;
Fig. 4 is pack into the half section schematic representation of a plurality of piston structures of the utility model.
Be to drive an inclined-plane guiding groove 2 on the piston 1 in placing cylinder 3 when the utility model is applied to two-stroke, the guide finger 4 that is installed on the cylinder 3 matches with it, and it is oblique mobile to prolong groove, the rotary main shaft 5 that is installed in middle part, piston 1 lower end closely is connected with two movable pulleies 7 that are installed in flywheel 6 middle parts, when engine running, flywheel 6 driven rotary main shafts 5 and piston 1 upper and lower motion.When guide finger 4 forced piston 1 to rotate up by the direction of guiding groove 2, this moment, intake valve was opened, during the dot location of piston 1 transposition cylinder 2, and IC Intake Valve Closes.In like manner, when guide finger 4 forces piston 1 to move downward cylinder 2 minimum points, finish once acting, combustion gas.
To place when the utility model is applied to two-stroke on the piston 1 in the cylinder 3 and open one tiltedly at guiding groove 2, the guide finger 4 that is installed on the cylinder 3 matches with it, and can prolong on the skewed slot, move down, a hole 8 is opened in piston 1 center, match with rotary main shaft 5 in hole 8, with the tipping of two movable pulleies 7 in the hole 8 bottom, rotary main shaft 5 one ends are connected with flywheel 6, the other end and two movable pulleies 7 closely cooperate, when 5 motions of flywheel 6 driven rotary main shafts, rotary main shaft 5 drives two static pulley 7 and rotates, and rotary main shaft 5 is along on the hole 8, move down, be accompanied by moving of axle 5, guide finger 4 rotates up in the direction that forces piston 1 by guiding groove 2 simultaneously, enter open this moment, during the dot location of piston 1 transposition cylinder 2, and IC Intake Valve Closes.In like manner, when guide finger 4 forces piston 1 to move downward cylinder 2 minimum points, finish once acting, combustion gas.
When the utility model is applied to the four-stroke process, piston 1 is connected as a single entity with main shaft 5, and closely cooperate with the movable pulley 7 that is installed on the flywheel 6, drive main shaft 5 by flywheel 6 earlier and reach the piston 1 that connects together with main shaft 5, guide finger 4 makes piston 1 move along guiding groove 2 rotations, intake valve is opened, and finishes air inlet.After piston 1 has turned round half-turn,, make piston 1 continue rotation and move by the cooperation of guiding groove 2 and guide finger 4.Simultaneously, inlet and outlet Men Jun closes, and finishes compression process, and this moment, piston rotated a week.In like manner, when piston 1 began to carry out second circle, the inlet and outlet door was closed, and began acting, and guide finger 4, guiding groove 2 force piston 1 to rotate, and finish the acting process.After finishing acting, flywheel 6 continues to drive piston 1 and rotates, and exhaust valve is opened, and finishes exhaust process.
With piston 1 center perforate 8, match with the rotary main shaft 5 that connects together with flywheel 6 in hole 8, movable pulley 7 is loaded on 8 bottoms, hole, this kind structure applications is in the four-stroke process, flywheel 6 rotations, main shaft 5 drives piston 1, and guide finger 4 makes piston 1 move by guiding groove 2 rotations, intake valve is opened, and finishes air inlet.Behind the piston 1 running half cycle, making piston 1 continue rotation by 4 cooperations of guiding groove 2 guide fingers moves, simultaneously, intake valve, exhaust valve are all closed, finish compression process, this moment, piston 1 rotated a week, in like manner, when piston 1 begins to carry out second circle, inlet and outlet Men Jun closes, and begins acting, and guide finger 4, guiding groove 2 force piston 1 to rotate, finish the acting process, after finishing the acting process, flywheel 6 rotates with the main shaft 5 drive pistons 1 that flywheel connects together, and exhaust valve is opened, waste gas is discharged, finish exhaust process.
The utility model can be adorned a plurality of pistons 1 in cylinder 2, dispose corresponding distribution, oily mechanism, is arranged to a plurality of firing chambers.Working procedure is identical with single piston.
