Description
Technical field
The present invention, about motor, more specifically relates to a kind of screwed pipe rotor of gas engine.
Technical background
A kind of rotor is disclosed for efficiently working medium transformation of energy machinery being improved in the method for propeller for turboprop engine efficiency and device thereof number of patent application 201410415779.3 1 kinds:
A kind of rotor, comprises cylindrical rotor solid of rotation, is less than 90 ° of both ends of the surface being communicated with rotor solid of rotation through a rotating body and is formed a kind of screwed pipe rotor to be greater than 0 ° clockwise or counterclockwise with rotor shaft direction angle by a screwed pipe or one or more screwed pipe simultaneously.
From screwed pipe entrance to outlet, be with the top layer of certain pitch arrangement at rotor solid of rotation between screwed pipe.
Screwed pipe entrance is that spacing is in the counterclockwise direction widened in sense of rotation.
A rotating body is provided with chamber.
Rotor, as the core component of energy conversion device, which is responsible the important task enthalpy of High Temperature High Pressure working medium being converted to outputting power, screwed pipe wherein subjects washing away of High Temperature High Pressure working medium especially, so it has many-sided requirement, but mainly intensity and refractory heat-insulating aspect.When the operating temperature of its working medium is lower than 400 DEG C, as long as rotor has enough mechanical strengths, the endurance impact of temperature on engine operation is little.But in combustion gas screwed pipe rotary engine, working medium combustion gas is often operated in about 1000 DEG C, if do not taked certain technical measures, can whole rotor be burnt red very soon, except heat dissipation increase lowers efficiency, rotating shaft also can be made to soften, thus affect the work endurance of motor.
For solving above-mentioned technical problem, the manufacture method of a number of patent application 201510252428.X motor screwed pipe rotor, have employed:
Get straight-run of pipe;
The flange equaling straight tube internal diameter at two external diameters establishes symmetrical rotary shaft hole, screwed pipe mounting hole respectively, one of them flange establishes plug hole, and is made up of axis hole annulus and screwed pipe mounting hole annulus two large small circle rings;
Curved good screwed pipe simultaneously with clockwise or counterclockwise orientation, two ends are inserted in two flange screwed pipe mounting holes and are fixed, then are inserted in straight tube, and two end flange and straight tube welding fix formation cylindrical shell;
In a rotating shaft, being axially welded and fixed at least one block length is less than length in cylindrical shell, and its rotating locus is less than the sheet metal of screwed pipe mounting hole internal radius;
Cylindrical shell is inserted in rotating shaft, only not establishing plug hole flange and rotating shaft to be welded and fixed;
Plug hole flange end is had upwards rotating shaft to be holded up;
By the operation instruction of refractory heat-insulating castable its furnishing oar, refractory heat-insulating castable is poured in cylindrical shell from flange plug hole, and vibrates bubble removing tamping, to fill up in cylindrical shell for this reason;
Naturally place and solidify 3 ~ 7 days, remove flange axis hole small circle ring;
Naturally place again and solidify 2 ~ 3 months, namely can be made into motor screwed pipe rotor.
Its shortcoming be refractory heat-insulating lower than 1000 DEG C, the intensity of the strength ratio ceramic post sintering pouring into a mould out with refractory heat-insulating material is low.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming, a kind of screwed pipe rotor of gas engine is provided.
The present invention is achieved by the following technical programs:
A kind of screwed pipe rotor of gas engine, comprise cylindrical rotor solid of rotation, screwed pipe rotor is by rotating shaft, tubular solid of rotation, metal shell forms, described tubular solid of rotation is with the integral sintered tubular ceramic body out of ceramic raw material, wherein sinter out to comprise and be less than to be greater than 0 ° clockwise or counterclockwise with rotor shaft direction angle 90 ° are communicated with tubular solid of rotation both ends of the surface more than at least two screwed pipes through tubular a rotating body simultaneously, tubular ceramic body inner circle and rotating shaft cylindrical are provided with corresponding spline, tubular ceramic body inner circle spline is inserted in rotating shaft cylindrical spline joint and is fixed together, tubular ceramic body cylindrical is inserted in metal shell and is connected and fixed.
During tubular ceramic body integral sintered with ceramic raw material together with rotating shaft, metal shell the screwed pipe rotor of sinter molding entirety.
Ceramic body is special cermacis
Rotating shaft is quill shaft.
Owing to have employed abovementioned technology, the present invention can receive following technique effect:
1, resistance to high temperature brings up to 1000 ~ 1200 DEG C;
2, there is high tenacity;
3, high-flexural strength;
4, high wear resistance;
5, excellent heat-shielding performance;
6, resistance to oxidation;
7, corrosion-resistant;
8, motor more can work lastingly.
Embodiment
Below embodiments of the present invention are further illustrated.
A kind of screwed pipe rotor of gas engine, comprise cylindrical rotor solid of rotation, screwed pipe rotor is by rotating shaft, tubular solid of rotation, metal shell forms, described tubular solid of rotation is with the integral sintered tubular ceramic body out of ceramic raw material, wherein sinter out to comprise and be less than to be greater than 0 ° clockwise or counterclockwise with rotor shaft direction angle 90 ° are communicated with tubular solid of rotation both ends of the surface more than at least two screwed pipes through tubular a rotating body simultaneously, tubular ceramic body inner circle and rotating shaft cylindrical are provided with corresponding spline, tubular ceramic body inner circle spline is inserted in rotating shaft cylindrical spline joint and is fixed together, tubular ceramic body cylindrical is inserted in metal shell and is connected and fixed.
Pottery classification has multiple, and only the ceramic raw material of special cermacis just has oxide ceramic raw material, nitride ceramics raw material, carbide ceramics raw material, ceramet raw material.With the pottery that these raw materials sinter out, there is the excellent properties such as creep under high temperature resistant, wear-resistant, corrosion-resistant, anti-oxidant, high temperature is little, the harsh working environment that metallic material and macromolecular material are difficult to be competent at can be born, be widely used in the fields such as the energy, space flight and aviation, machinery, automobile, metallurgy, chemical industry, electronics, become a development class stupalith very rapidly.Believe and do not excavated more high performance pottery by people in addition.Practice and theory show, object conductivity is better, and its heat-conducting property is also better, but pottery is nearly all insulator, so pottery has excellent thermal insulation performance.
