Abstract
The utility model relates to a triangle rotor internal combustion engine. In the triangle rotor internal combustion engine, rotor cooling problems result in the lubricating problem and the problems of seal, etc. of the internal combustion engine, which hinders the development of the triangle rotor internal combustion engine. The utility model causes rotor cavities to be communicated by adopting the assembling mode of a pin shaft or adopting the assembling mode of an inner tooth ring crank and an inserting gear shaft and simultaneously adopting a structural mode that a main oil hole is arranged on an assembling type triangle rotor. Thereby, cooling media can be caused to form good circulation. The utility model effectively solves the cooling problem of the triangle rotor and the problems of lubrication, etc. among a rotor, a cylinder cover and a cylinder body.
Description
A kind of four-stroke oil cooling of the utility model three-apexed rotor internal-combustion engine.
In the prior art, three-apexed rotor adopts cast inblock formula structure, when it rotates, cooling medium can not enter rotor chamber, if when the three-apexed rotor internal gear adopts disconnection or half of design, change in the chamber though cooling medium can enter, cooling medium can not cool cycles.So the cooling problem of three-apexed rotor is difficult to effective solution so far.Thereby the mutual airtight problem that causes three Seal cages in the cylinder body.Rotor and cylinder cap, a series of problems such as the lubrication problem between cylinder body, this is that rotary polygonal piston engine is failed one of major reason of applying so far.
Task to be solved in the utility model is the effectively problem of cooling of rotary polygonal piston engine.Provide a kind of cold oil in rotor, to change in internal-combustion engine by the circuit triangle.
Solution of the present utility model is:
A kind of three-apexed rotor internal-combustion engine comprises three-apexed rotor, pto, and cylinder body, its special way is: described three-apexed rotor (13) is three fabricated constructions; The floor of three silver coins (8) is provided with main oil-hole (1); Described pto is bent axle (a 14) formula drive mechanism.
Three-apexed rotor floor (8) in the technique scheme is provided with a plurality of oilholes (1), and oilhole (1) forms certain angle with the floor face.
Bent axle in the technique scheme (14) is used assembled crankshaft, is made of crank (17) and line shaft (18).
Fig. 1 is a rotary polygonal piston engine overall structure schematic representation;
Fig. 2 is a three-apexed rotor overall structure schematic representation;
Fig. 3 is the perspective view of a rotor of three-apexed rotor;
The side view of one rotor of Fig. 4 three-apexed rotor;
Fig. 5 is a kind of bearing pin assembled crankshaft;
Fig. 6 is a kind of crank of assembled crankshaft;
Fig. 7 is the line shaft of Fig. 6 assembled crankshaft.
Below in conjunction with accompanying drawing the utility model is passed through specific embodiment, be described in detail: 1-main oil-hole 2-apical axis groove 3 assembling bolt mouth 4-oil groove 5-assist oilhole 6-fitting recess 7-oil duct 8-floor 9-assembling wedge 10-seal groove 11-spark plug 12-cylinder body 13-three-apexed rotor 14-bent axle 15-intake valve 16-exhaust valve 17-crank 18-line shaft
Referring to Fig. 1, rotary polygonal piston engine is made up of three constant amplitude circular arcs three-apexed rotor that surrounds and the cylinder body that corresponding rotation envelope forms.This cylinder body is separated into three mutual sealed space by three-apexed rotor, in its spatial volume generating period change procedure, finishes air-breathing, compression, the work done of internal-combustion engine, the work cycle of exhaust.
Referring to Fig. 2, Fig. 3, three-apexed rotor is to be formed by three assemblings.On rotor, be provided with dovetail groove, assembling wedge and mounting bolt hole.Be used for assembling and the adjustment three-apexed rotor.The drift angle that is located at rotor is in the seal groove at apical axis groove and floor place, makes three-apexed rotor can seal the space of three sealings in cylinder body.
In order to make cooling medium form circulation in rotor chamber, the floor of rotor is provided with main oil-hole, and the interior both sides of rotor chamber are communicated, and according to the watt level of motor and the demand of heat radiation, a plurality of main oil-holes can be set on floor.Auxilliary oilhole and oil duct also can be set in the both ends of the surface of three-apexed rotor apical axis end and three-apexed rotor, the just apical axis of rotor, sides etc. locate that good lubricated and cooling is all arranged.After cooling medium passes through filler opening, enter rotor chamber, lubricant oil enters the opposite side of rotor chamber from a side of rotor by main oil-hole, and some lubricant oil is in the apical axis and the end face both sides that enter into three three-apexed rotors through auxilliary oilhole.Form good lubricated and cooling, thereby take away the heat of rotor.Enter sump by oil outlet,, pump into oil radiator, dispel the heat, also can enter filler opening once more, thereby form good cool cycles by oil pump through the supercooling precipitation with after filtering.
Main aperture oil can be provided with certain angle with the floor face.Fixed when the power of motor, rotating speed is timing, and this moment, the burning capacity and the heat of fuel oil were also just fixed.Thereby specific heat and proportion according to oil calculate oily flow.The size of this angle is set according to flow requirements.When rotor rotated, the pumping effect of this angle can quicken the circulation of cold moving oil.The scope of general angle all is located between 15 °-45 °.
Referring to Fig. 4, Fig. 5, pto adopts fabricated construction.This assembly structure form is that a kind of line shaft and crank are one whens assembling, adopts the bearing pin assembling form.
The crank of another kind of form adopts the internal gear structure, and line shaft adopts the gear shaft form, and when assembling, two gear transmission axles insert bent axle from the both sides of crank.One side of line shaft cooperates with the gear ring on the end cap, can reduce the impact to axle like this, induces it to move in ring gear.During the three-apexed rotor assembling, on bent axle, can be provided with bearing shell.The bearing of line shaft is arranged on the cylinder cap, and just the gap of bearing communicates with the oil duct of cylinder cap, thereby forms good cooling and lubrication effect.
The utility model adopts assembled triangle rotor and assembling type crank structure in multicylinder engine, in single-cylinder engine, can adopt cast-in-block three-apexed rotor and assembled crankshaft.
Advantage of the present utility model is as follows:
1, the utility model increases the inner chamber of three-apexed rotor because adopting the crank-type structure, makes the lubricating oil energy Rapid cold moving rotor.
2, the utility model adopts and at floor main hydraulic fluid port form is set, and rotor chamber is communicated, and formation is started The good circulation of machine cold oil.
3, the utility model adopts three assembled three-apexed rotors to solve the device problem of multicylinder engine.
4, little, in light weight, the compact conformation of volume of the present utility model, the range of speeds is big.
