The mechanical supercharger includes a casing with air inlet pipe and exhaust pipe, a eccentric columnar rotor, a coupler mounted to one end of the rotor, and movable blades mounted onto the surface of the rotor. The mechanical supercharger is connected via the coupler to a rotation mechanism rotating its rotor. It operates on the eccentric rotor and supercharging body to realize scavenging supercharging of the blades. It has blade slots in special angle to reduce friction between blades and the casing and vibration and raise scavenging effect. The mechanical supercharger has simple structure, small size and high supercharging effect, and is suitable for use in motorcycle and automatic engine.
Description
Technical field:
The invention belongs to engine art, particularly motorcycle or motor car engine mechanical pressurizing apparatus.
Background technique:
Available engine mainly adopts turbosupercharger and mechanical supercharger supercharging.Turbosupercharger is to drive with nearly 1000 ℃ high-temp waste gas that motor is discharged, and its power is that the power train by motor oneself directly drives its rotor, influenced by engine speed, has shortcomings such as speed of response is slow, the life-span lacks.The disclosed internal-combustion engine mechanical supercharger of Chinese patent (ZL200410023340.2). this pressurized machine is for being contained in two axle heads and intermeshing active synchronization gear and driven synchromesh gear, have on the diaxon in the rotor chamber to be meshing with each other and three lobe rotor and three lobe rotor that its end face molded lines is conjugate curve, it is for cylindrical structure or turn round impeller structure.Above-mentioned mechanical supercharger is compared fast, the long service life of speed of response with turbosupercharger, but owing to mesh supercharging by gear and the rotor that is packed in two axles, noise is bigger during work, and structure more complicated and volume are big, and is low by bidentate wheel supercharging volumetric efficiency.
Summary of the invention:
The purpose of this invention is to provide the engine mechanical pressurizing apparatus that pressurized effect is good, noise is low and simple in structure.
The solution of the present invention is: comprise the suction tude and the outlet pipe that are installed on the housing two ends, eccentric column rotor is housed in the housing, rotor one end is equipped with shaft coupling, and the blade removable mounting is in the rotor cylinder.
The rotor cylinder has several long strip blade grooves, and the long strip blade is inserted in the blade groove; Rotor has 4-8 blade groove, and blade quantity is identical with blade groove, and the blade groove optimal number is 6, is inserted with 6 blades in the blade groove.Blade groove the inner is a with respect to the clockwise drift angle of rotor axis, and drift angle a is 30 ° to 32 °, and best drift angle a is 30.5 °.Blade material adopts carbon steel, and length of blade is less than or equal to blade groove length.The suction port sectional area of suction tude is less than the relief opening sectional area of outlet pipe.
Advantage of the present invention is: supercharging device links to each other with rotating mechanism by shaft coupling, drives the rotor running, utilizes rotor and supercharging body eccentric center principle, realizes the purpose of blade scavenging supercharging.Adopt the blade groove of special angle, can improve friction, the vibrations of blade and housing, strengthen scavenge effect.Said apparatus is simple in structure, and volume is less, and pressurized effect is good, is applicable to automobile and motorcycle engine supercharging.
Description of drawings:
Fig. 1 is a shape assumption diagram of the present invention.
Fig. 2 is the A-A direction sectional view of Fig. 1.
Fig. 3 is the B-B direction sectional view of Fig. 2.
The accompanying drawing mark is as follows: 1-supercharging body, 2-suction tude, 2 '-suction port, 3-outlet pipe, 3 '-relief opening, 4-rotor, 4 '-blade groove, 5-blade, 6-fore shell, 7-back cover, 8-shaft coupling, 9-bearing, 10-bearing.
Embodiment:
With reference to Fig. 1, setting Fig. 1 finding place is the front portion of Fa Benming, and the back side is the rear portion, and left and right directions is with reference to this accompanying drawing.Supercharging body 1 of the present invention is made up of fore shell 6 and back cover 7 (see figure 2)s, and the inner chamber that housing forms is cylindrical, and suction tude 2 and outlet pipe 3 are equipped with in two ends, supercharging body 1 left and right sides.
With reference to Fig. 2, the fore shell 6 of supercharging body 1 and back cover 7 respectively are provided with bearing 9 and bearing 10, and rotor 10 is installed on the pressurized machine intracoelomic cavity, and two ends are by bearing 9 and bearing 10 supportings.Rotor 4 stretches out fore shell 6 one ends shaft coupling 8, and this shaft coupling 8 connects with rotating mechanism, for supercharging device provides power.
With reference to Fig. 3, rotor 10 is cylindrical, and with cylindrical cavity off-centre, and rotor 4 diameter of sections are less than the intracavity section diameter.Rotor 4 cylinders evenly have six blade grooves 4 ', and blade groove 4 is a long strip, and blade groove 4 ' number also can be 4 to 8.Depart from clockwise in inner rotor 4 axle center relatively of blade groove 4 ', and its drift angle a is 30 ° to 32 °, and best drift angle a is 30.5 °.Six length of a film strip blades 5 are inserted in the blade groove 4 ', and the length of blade 5 is equal to or slightly less than blade groove 4 ' length.Blade 5 can slide in blade groove 4 ', and the employing of blade 5 materials is high temperature resistant, the carbon steel of high abrasion.Suction port 2 ' the sectional area of suction tude 2 is less than the relief opening 3 ' sectional area of outlet pipe 3.
Above-mentioned supercharger arrangement can be independent of motor to be assembled as an annex, and rotor itself does not need to lubricate, and need not oil leab.Link to each other with rotating mechanism by shaft coupling 8, thereby obtain power.Rotating mechanism drives rotor 4 rotations, and blade 5 rotates with rotor 4, utilizes the eccentric design of rotor 4 and pressurized machine intracoelomic cavity, and the gas that blade 5 is located suction port 2 ' is expressed to relief opening 3 '; Because the sectional area of relief opening 3 ' is less than suction port 2 ', gas increases at the air pressure of relief opening 3, realizes the purpose of blade scavenging supercharging.Adopt the blade groove of above-mentioned angle, can improve friction, the vibrations of blade and housing, volumetric efficiency improves, and strengthens scavenge effect.The said structure pressurized effect is good, noise is little, and simple structure, volume are little, and cost of production is low, and it is little to take up room, and can be widely used in motorcycle or motor car engine supercharging.
