Abstract

The present invention relates to refrigeration, air compression, liquid transfer and other technological field. The said convex-concave rotary wheel machine is easy to manufacture, smooth in operation, wide in use range and low in cost and has many other advantages. It is used in compressor and blower, as well as liquid pump, liquid or gas driver, brake, flowmeter and many other machine and equipment.

Description

Convex-concave rotary wheel machine

Be used for air compressing, refrigeration, liquid conveying etc.

As shown in Figure 1, it be by cam and the recessed close contact of taking turns in the body that rotation space is tightly arranged, make the double wedge can be corresponding with groove by contraposition gear (at the uniform velocity), protruding, the recessed wheel can be rotated.Hence one can see that, and the double wedge rotation time can force the inner fluid of its space (can comprise groove) to be extruded respectively and sucked by access hole, and can be made by fluid pressure that the double wedge interlock is protruding, recessed takes turns rotation.

Here the concave, convex wheel is meant the fluted and double wedge of difference on cylinder bodily form wheel; The shape of groove, double wedge is that shape wherein such as other line of motion trace, round wire, straight line (axial flow machine can be helix) is formed.

Pad in convex-concave rotary wheel machine, bearing (or axle sleeve), axle etc. are used for reducing friction etc.The transmission interface can flexiblely be connected with axle, can directly link outer shaft or increase drive wheel on axle, gets in touch by chain or belt and outer shaft, and taking turns end face, inside and body in convex-concave has recessed road and hole etc. to be used for effects such as balance pressure and fluid passage.

In order to make this machine that good performance be arranged, can establish the lubricated wet goods of fricting strip (or ring) in recessed road increases the resistance of convection cell, when essential, can establish elastomeric material or make the little tooth of engagement etc. at wheel face.The contraposition gear also can directly be fixed or accomplish on the convex-concave wheel.

Because this machine can have several functions, thus need set up the accessory relevant with function, as accessory or the setting that makes the fluid non-return effect arranged in outlet.The shape of its gateway, quantity, variable positionization are so that fluid smoothness etc.

The size of each part in the convex-concave rotary wheel machine (comprising double wedge, groove), ratio, quantity, shape etc. can change or have additional by accompanying drawing 1 principle the accessory of certain function, as long as body cooperates thereupon, just can make the product of certain function.

The beneficial effect that this invention has: 1. energy transformation ratio height; 2. noise is little; 3. it is wide to make the material therefor range of choice; 4. be suitable for manufacturing; 5. long service life; 6. using scope is wide; 7. the design scheme selection of convex-concave rotary wheel machine and expansion face are big.

As shown in Figure 2, its body can be divided into that cutting line position flat cutting becomes two parts among the figure; Can be two parts by diaxon axle center subdivision also; Make it to be suitable for and make and assembling.

Each constituent element comprises contraposition gear, axle, cam, recessedly takes turns, pad, axle sleeve (or bearing), transmission interface, check valve block, fricting strip etc., can make according to methods such as materials mould-forming or machinings.Each part (such as axle and cam or recessed the wheel) that can be fixed together can be fixed when moulding during with mould molding.Each several part can gluing (at this moment having cooperations such as hair side or groove, hole for injecting glue), press methods such as knot or screw be fixing.

The convex-concave design that makes the accurate contraposition of two-part, reduces the slit is arranged on the body.Fricting strip (or ring) is arranged in double wedge and body, and body has corresponding cooperation, and such as accompanying drawing 1, the body circular portion at fluid inlet place is as when double wedge has fricting strip, can make non-circular and removes a part, can pass through smoothly when making the double wedge rotation.Fricting strip (or ring) is arranged in the body for another example, can make bearing between axle and axle, locomotivity be arranged, make cam and the recessed total energy close contact of taking turns, guarantee when working very effective.

Claims

1, a kind of convex-concave rotary wheel machine for refrigeration, air compressing, liquid conveying etc. is characterized in that: cam and the recessed combination of taking turns that interaction force directly takes place for main utilization and fluid refered in particular in cam and the recessed combination of taking turns, cam and the recessed combination of taking turns; Can comprise rotating parts such as making its reliable contraposition gear that effectively moves, axle in the combination; Cam and recessed the wheel can include its related accessory that certain function is arranged; The quantity of each several part, proportionate relationship, combined method can change in the combination; Make Fluid Flow in A, comprise convection cell pressurization and suction, or meter flow, make protruding, the recessed wheel that obviously protruding or recessed various shapes are arranged that gear combination gets up to be used for above-mentioned functions that is different from that one or more functions are wherein arranged that rotates or stop of taking turns of double wedge interlock by fluid pressure.Utilize cam and the recessed combination of taking turns be placed in can with its close-fitting body that corresponding function and shape arranged in because cam contacts tight and double wedge can be corresponding with groove with the recessed wheel face of taking turns when rotating, cam and recessed the wheel can be rotated, so just can be to make Fluid Flow in A comprise convection cell pressurization and suction or meter flow, by fluid pressure or compel to wait make the double wedge interlock protruding, recessed take turns rotate or stop etc. the mechanical of one or more functions wherein arranged or arrange etc.

2, according to claims 1., it is characterized in that: participate in finishing above-mentioned certain function owing to one or a few double wedge and groove when cam and recessed combination rotation work of taking turns.

3, according to claim 1., it is characterized in that: cam and the recessed combination of taking turns are placed in the corresponding body, owing to have only a few double wedge, so it has bigger fluid to occupy the space, double wedge also can extrude utilization to the fluid in the groove in the lump, thereby makes its very effectively pressurized gas.

4, according to claim 1., it is characterized in that: the each several part in cam and the recessed combination of taking turns comprises that double wedge, groove are along with the needs of certain function and performance etc. can be done very big change such as quantity, shape, ratio, position, size, increase setting.

5, according to claim 1., it is characterized in that: (1) also can be few friction that has of sliding, thereby can make protruding, recessed big I of taking turns that different changes is arranged owing to both can be rolling friction between cam and recessed the wheel.(2) it protruding, recessed take turns and body in some necessary position fricting strip (or being the resistance of drag ring for increasing convection cell) can be set.(3) its double wedge, groove can adopt round wire, motion trace, straight line, other line to combine, and make it also not influence overall performance at some position defectiveness very much.(4) cam and recessed contact-making surface of taking turns can arrange the resistance that little engaging tooth (or elastomeric material) increases convection cell sometimes.
