Description

Technological Field:

This invention will involve the fluid expanding or compressing technologies on fluid channel, which belongs to the form of volume, and it has particularly decisive meaning in the reliability of the outstanding performance of bias cylinder rotary expanding and compressing mechanism with blades for traversing shaft. Thus, this technology can be applied from basic theories to production practice.

Technological Background:

As we all know, the invention of steam engine marks the beginning of the industrial revolution, while the key technology in transforming steam expansion to mechanical kinetic energy originates from the fire-blowing bellow invented by Chinese blacksmiths. Although this technology has been improved many times, because linear reciprocating inertia force doesn't match the common machinery rotation, the efficiency of machines involved in reciprocating piston expanding or compressing mechanism will definitely be low. To allow the fluid expansion or compressor be matched with the mechanical rotation, people adopt the non-volume turbine form, but due to the leakage between the blades and the leakage between the impeller rotor and the turbine stator, they still cannot get an ideal Energy Efficiency Ratio (EER). Why do we call it an ideal EER? This is because the ideal EER has been calculated using relative theories on mechanics through the form of volume for a long time. People have made many efforts in matching the form of volume with the mechanical rotation and invented a variety of expanding or compressing mechanisms. Although the EER of compressor made by screw mechanism and turbine mechanism in current products is relatively high, it is still far away from the ideal EER. In addition, because the structural birth defects cannot be used for expansion in place of the reciprocating piston or turbine form, people couldn't fundamentally conserve energy: also, the transformed heat will diffuse into the Earth's atmosphere, which will lead to a devastating weather disaster. Therefore, invention of fluid expanding or compressing mechanisms with high EER and good reliability has become a top priority in this modern society: otherwise, the more this world is automated, the more aggravated the vicious circle of energy use will be.
It was still Chinese blacksmiths who recognized this predicament of energy use and then invented the most ideal bias cylinder rotary expanding or compressing mechanism provided in fluid channel with blades for traversing shaft in theory. This mechanism is supported by the supporting frame, the side on which fluid flows in and out is connected with the expanding or compressing work system, while the other side enters the elliptical type linear curve barrel stator, within which the rotor with concave grooves is placed at the eccentricity department, and blades for traversing shaft is inserted in the rotor with concave grooves. When it is restrained by the round end cover, the blades for traversing shaft can do reciprocating activities at the axis of the rotor with concave grooves, and it is coordinately restrained by the curve barrel stator at the same time, then it can spin continually which constitutes the rotary compulsory and continuous expansion or compression.
We know that the technical requirements for air flow are much higher than liquid flow. To experimentally demonstrate the superior performance of such mechanisms, in view of its expansion function, this mechanism is specially prepared as the basic form of gasoline engine which can meet the essential requirements of 4 stoke technology; in the aspect of its compressed function, this mechanism is specially prepared as the closed fixed-frequency air-conditioning compressor, and an EER comparison experiment has been done between it and the most advanced vortex mechanical closed fixed-frequency air-conditioning compressor in the world. A popular introduction of this experiment is as follows: the two experimental machines are started on the premise of oil-lubricated stationary rotary, and continued working two hours calculated as a test period. The experiment of gasoline engine serving the function of expansion is a principal one, the supply of oil, air and water is stable and sparks are generated by the piece bunt. At the first test period, the sound is comparatively crisp, and the speed is extremely quick; at the second test period, the sound is comparatively turbid, and the speed is relatively slow; at the third test period, the sound is more turbid, and it finally stopped running with an explosion. The work pressure of the air-conditioning compressor serving the function of compress is 22-4 Kg, the refrigerant is 134a, the motor made by myself running at a speed of 1440 rpm. The EER at the end of the first test period is 6.1, which is about twice the EER of the most advanced vortex mechanical air-conditioning compressor, which is 3.3, and the chatter and noise is cut by half; the EER at the end of the second test period is 5.8; the EER at the end of the third test period is 5.4; th e EER at the end of the fourth test period is 4.9; ··· With the increase of test period, the EER gradually declines.
Shortly, the inventor carefully opened these two experimental machines, and easily found a common problem: that is, the volume separated by such mechanism is no longer closed and has developed a leakage, mainly because the matching gap between the blades for traversing shaft and the curve barrel stator is too big. In fact, this problem had been strongly recognized long ago when the parts were designed and manufactured, particularly the largest gap between the two ends of blades for traversing shaft the curve barrel stator line after the assembly of its parts is 0.04 mm, while the short axis of elliptical line curve barrel stator is 108 mm. Its hollow shaft hollow piece is made of HRC72 cemented carbide, and its curve barrel stator is made of HRC50 bearing steel after heat treatment. By rights in the case of oil lubrication, mirror grinding wear of the two should be minimal, but the experiment, with the compressor as an example, proved that the blades for traversing shaft will be worn and 0.02 mm shorter after each test period, and the axis of the curve barrel stator far from the rotor will be worn and expanded 0.002-0.004 mm: that is to say, the linear curved surface of curve barrel stator which is processed and formed in an extremely uneconomical way will be transformed. By this token, the key problem in popularizing this mechanism from the basic theories to production practice will be inventing a new mechanism which can not only play the advantages of rotary compulsory and continuous separated volume of such mechanism, but also solve the contradiction of wearing and closing between the blades for traversing shaft and curve barrel stator, and improve the problem of wearing and closing in the other place. It may also be a key factor in solving the problem of human's energy conservation and the Earth's meteorological disaster.

Summary of Invention:

As is known to all, wearing is a natural phenomenon. We must use materials with a small friction coefficient and low wearing rate, and rely on the medium of lubricant to close without friction. However, it is proved that this is far from enough in the experiments of such mechanisms:

particularly in the cooperation between the blades for traversing shaft and curve barrel stator, there must be another component embedded into the two sides of the blades of the traversing shaft to ensure its reliability, which can reduce its friction and give its friction compensation to avoid hard grinding and scratching between the blades of the traversing shaft and the similar lines of the curve barrel stator.

This invention will provide a specialized movable, wearable, closed new structure, whose outer sections are composed of arc edges and it can be designed as two sets of patterns in accordance with the technical requirements of air and liquid: one set is setting a wearable sealing member whose outer edge shape is "6" or "Ω" at the matching place between the blades for traversing shaft and the curve barrel stator, and using the protruding part of the circle to form backhoe swing closing and compensate for the wearing. The other set has one set setting a wearable sealing member whose outer edge shape is positive circular at the matching place between the blades for traversing shaft and the curve barrel stator, even adding bearings to stabilize, and using rolling to evenly replace the worn place or making good use of elastic stress to constitute smooth rolling, closing, and compensate for the wearing.
Therefore, it is necessary to pay special attention to this: with the existence of the above wearable sealing member, the original linear curved surface of curve barrel stator processed and formed an extremely uneconomical way has now become very economic, which will be able to adapt to a variety of molding machines for processing, and the volume formed under the conditions that the diameter and short axis etc. are equal. This is because now they can be waist-round curved surfaces, linear curved surfaces connected by several round arc lines, oval curved surfaces, or linear curved surfaces connected by oval arc and round arc etc. The calculation told us when the bias distance between the rotor with concave grooves and the curve barrel stator is in line with the better configuration of volume structure, comparing these curved surfaces with those correct and precise curved surface, the largest deviated curved surfaces is 0.5% longer than the short axis in only two places. The above wearable sealing member can fully compensate for this gap, not to mention that the mechanical deviation has always been everywhere. In addition, with the existence of the above wearable sealing member, its wearable closed performance is enhanced, and its expansion function can be fully adapted to the technical requirements of internal combustion engine. As a result, there is a qualitative change in the major invention features of the original expanding or compressing mechanism, and using this invention can greatly improve the technical reliability and popularity, and its EER can be greatly enhanced at the basis of 6.1 (Fortunately, this mechanism was originally invented by myself: no one else has ever acquired such a high EER and the hardship of argument is avoided.)
With the above invention, we can also improve the corporation between the rotor with concave grooves and the blades for traversing shaft, which is essential to getting a higher EER.

Technological Effects

Energy is conservative. According to the experiments and the calculation, this invention can have more than one EER of the current most advanced expanding or compressing mechanism in the world without any doubt. Thus it naturally has larger pressure, softer noise, slight chatter and light structure. It can not only take place of the current expansion or compress mechanism in form of volume, but also partially replace the current turbine form expansion or compress mechanism. In addition, many new inventions could be developed because of its excellent performance.
As we all know, in all the power station, power is generated by the fluid flowing through the turbine form of the turbine rotor. In principle and structure, since there is space between the blades and the turbine stator, the turbine rotor will have pressure leakage, which results in the loss of at least half of the energy. However, if this invention is applied, the leakage is avoided and the flow rate matches with the flow velocity. Then the energy effect will be doubled.
As is well known, internal combustion engine has expansion in forms of volume and turbine, and both forms have very low EER. If this invention is applied, it is certain that the current form of volume will have output time with the same amount of fuel, and then completely replaces the form of turbine.
We also know that energy conservation and security of carriage machinery have always been two major and enduring problems. If this invention is applied and extended to the air transmission system with gas storage containers, then the power plant of the carriage machinery will work uniformly and it can form thermal expansion through collection of thermal energy. The driving force will first be from large to small and the velocity can be changed continuously. Not only will the force be very appropriate and the surplus energy be stored, but also all-wheel drive and all-wheel steering can be realized. In addition, it also allows carrying machinery to include big external airbags, etc. Thus the above mentioned two problems are solved. If one has no courage to use it in cars, it can at least be used on bicycles and bicycles with air or liquid flows, which can be folded into luggage carts.
As we all know, the air-conditioning or refrigeration compressor has always been consuming a large amount of energy. If this invention is applied, there is no doubt that energy will be conserved.
As we all know, experiments show that using the antirust metal melted by supersonic high-pressure air flow impulse electric to bombard the steel surface is the best way to keep steel from being rusted. But because the air compression equipment is large, it is not only uneconomic, but also inconvenient, so it has been staying in the laboratory and cannot be used. Using this invention will minimize the equipment to a shape more convenient than operating backpack-type flamethrower, which is the most convenient way of solving the problem of steel corrosion.
The scope of application of this invention is extremely wide. The above is just an inspiring tip, and if it is applied to air motor, liquid motor, air pressure pump, liquid pressure pump, vacuum pump, mixed-flow pump, it will cover almost the entire field of industry and life. It is obviously a big machinery revolution. It is the core technology to solve the problem of human's energy conservation and the Earth's meteorological disaster, and it is also a common technology easily understood by every people possessing mechanical common sense.
The above is only to illustrate the basic implementation program of this invention, not to make any corresponding restrictions on this invention in any form; thus, if there is any change or improvement related with this invention, all of them should be included in the protection scope of the claims of this invention.

Embodiments

Evidently, THE INVENTORprovide an expanding or compressing mechanism on fluid channel; it includes a supporting frame (1), an import (2) and export (3) of the fluid channel, an un-round type curve barrel stator (4), a rotor with concave grooves (5), blades for traversing shaft (6), a round end cover (7), and a member for transmitting force (8). Its features are: the movable wearable sealing member (9), (10), (11) whose outer surfaces and edges are constituted by arc lines whose matching place is between the blades for traversing shaft (6) and the curve barrel stator (4). Thus, on one hand, the difficulty of processing curve barrel stator (4) which matches with it will be reduced and be adapted to a variety of molding machines: on the other hand, the friction is reduced when matching blades for traversing shaft (6) with curve barrel stator (4) and get compensation for friction, and reliable closing is formed (as is shown in Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5).
Before this we should realize that the linear curved surface of un-round type curve barrel stator (4) can be a waist-round curved surface, linear curved surface connected by several round arc lines, oval curved surface, or linear curved surface connected by oval arc and round arc, even linear curved surface connected in the way of polar coordinates or equal mathematical models etc. because when the bias distance between the rotor with concave grooves (5) and the curve barrel stator (4) is in line with the better configuration of volume structure, comparing these curved surfaces with those correct and precise curved surface, the largest deviated curved surfaces is only 0.5% longer than the short axis in two places: that is to say, if the short axis of the most deviated curved surface is 100 mm, there are only two places 0.5 mm larger, and if the running wear-in technology is applied, it will be 0.2-0.1 mm, even "troposphere", but after "troposphere" deviation will be formed again by hard grinding and scratching.
Therefore, this invention will provide two basic types of movable wearable sealing members whose outer surfaces and edges are constituted by arc lines:
The features of the first type are the movable wearable sealing member (9), (10) (as is shown in Figure 1 and Figure 3) whose outer edge shape is "6" or "Ω" are set at the matching place between the blades for traversing shaft (6) and the curve barrel stator (4) to form backhoe swing closing. Why do we call it wearable and closed? This is because if the two ends of the blades for traversing shaft (6) are semi-circular curved surfaces, when cooperating with the biased un-round curve barrel stator (4), its two ends can always squeeze out extra space, which can make the semi-circle changed to the shape of "6" or "Ω" inserted to it and swing. And at least 20-60% of the circular parts in the shape of "6" or "Ω" will form the backhoe piece as the thickness and width stretched out to one side. Such thick movable backhoe pieces adding wearable materials can naturally resist the long-term friction and compensate the above deviation closing.
The features of the other type are the movable wearable sealing member (11) (as is shown in Figure 2, Figure 4 and Figure 5) whose outer edge shape is positive circular set at the matching place between the blades for traversing shaft (6) and the curve barrel stator (4) to form smooth wearable closing. Why do we call it wearable and closed? This is because smooth rolling can circularly and evenly replace the worn place to compensate the size lost by friction, and at the same time, makes the curve barrel stator (4) face rolling friction, which is the best place for wearable materials with a small friction factor and wearable coating technology. It will naturally resist the long-term friction and compensate the above deviation closing. if we increase our awareness before using.
To improve smooth wearable closing, its feature is that not only the movable wearable sealing member (11) whose outer edge shape is positive circular is set at the matching place between the blades for traversing shaft (6) and the curve barrel stator (4), a rolling bearing (12) is affixed (as is shown in Figure 2 and Figure 5). If the rotary direction is confirmed, the centre of its rolling wearable closing mechanism (11) and the centre of the rolling bearing (12) can form a certain gradient compared with curve barrel stator (4). So, how can it be unable to resist the long-term friction and compensate the above deviation closing?
For the closing and friction between the rotor with concave grooves (5) and the blades for traversing shaft (6), their feature is that the backhoe wearable sealing member (13) and (14) whose outer edge shape is "P" or "L" is set at the matching place between the rotor with concave grooves (5) and the blades for traversing shaft (6) (as is shown in Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5). We should know that the rotor with concave grooves (5) must be worn if there are blades for traversing shaft (6) sliding for a long term by the role of fluid pressure within it, and the wear and tear must lead to a leakage, which will form a yaw angle through the axis of rotor with concave grooves (5). If this continues for a long time, this leakage will make the high-pressure fluid directly rush to the low-pressure area, resulting in an unusual expansion or compress of this mechanism. Therefore, placing the backhoe wearable closing mechanism (13) and (14) is essential.
In order to in general dwindle the wear and tear and reduce the friction so as to achieve good closing (as is shown in Figure 1, Figure 2, Figure 3, Figure 4 and Figure 5), this invention opens a groove (15) at the matching place between the rotor with concave grooves (5) and the blades for traversing shaft (6), and set up a rolling column (16) in the groove to constitute the rolling cooperation. As we all know, the simplest way of using rolling column is to make the diameter of the column slightly larger than the surface height, which can not only make it roll easily, but also reduce the pressure.
According to the above technical program, we can easily find that this invention is basically centered on the principle that the blades for traversing shaft can be flexibly wearable and closed between the curve barrel stator and the rotor with concave grooves. To this end, THE INVENTORspecially call the bias cylinder rotary expanding or compressing mechanism with pieces for traversing shaft bias cylinder rotary expanding or compressing mechanism with blades for traversing shaft through this invention, and referred to as rotary expanding or compressing mechanism with pieces for traversing shaft.
