TW200304982A - Scroll type fluid displacement apparatus with fully compliant floating scrolls - Google Patents

Abstract

The invention includes a "floating scroll" mechanism for scroll type fluid displacement apparatus. The dual orbiting scroll has spiral vanes on both sides of the end plate. In a floating scroll, the orbiting scroll is dynamically well balanced, axially and radially. The scrolls are fully or semi-axially and radially compliant for maintaining minimum contacting forces between components, hence achieving good sealing for high speed, high efficiency, low friction wear and power loss. A crank shaft-sliding knuckle and/or peripheral crank handles-sliding knuckle mechanism provide the dual orbiting scroll with radial compliant capability. A synchronizer is used to synchronize the orientation of the crank handles to avoid the mechanism from jamming during operation and start up.

The above-mentioned patent provides a so-called, "double scroll" structure, that is, two scroll pieces extending back to back from the two end faces of the end plate. The double scroll structure makes the axial fluid of the end plate act on the axial direction of the end plate. The forces are largely offset or balanced with each other. Therefore, there is no need for a thrust bearing that can withstand the axial force experienced by the moving scroll, and the corresponding wear and power consumption are also reduced.

However, in the previous technology, whether it is a center drive or a peripheral drive, the moving radius of the moving scroll is fixed. U.S. Patent [192,152] to Allen E. Armstrong et al. Discloses a radially k-shaped connection mechanism to accommodate different thermal expansions between the scroll and the frame of the base. The typical "radial compliance" widely accepted in the industry is a mechanism that refers to a mechanism in which a movable scroll provides free movement in the radial direction until the side walls of the dynamic and static scrolls come into contact and thereby the air cavity is closed. When the incompressible fluid = is enclosed in the air cavity or the debris is caught between the scrolls, the moving scroll can make a radial concession from the static scroll to the above situation. It is exposed in ~ ^ This so-called "radial compliance" connection mechanism can provide the freedom of radial motion of the movable scroll, so it is not a true radial compliance mechanism. Li disclosed a shaft coupling device that can rotate around a fulcrum. This is also a mechanical radial compliance mechanism. At this machine

200304982 V. Description of the invention (3) In the structure, a patent for a connecting device of the movable vortex also provides contact with the bottom surface of the pressurized gas, and the high-negative oil scroll in the oil-free compressor can be used at high speeds that can rotate thousands of revolutions around the fulcrum. Peripheral crankshaft connection mechanism for preventing rotation from being exposed to the press. However, it weakens the dynamic and static [content] in order to overcome the “all-around scroll” π plate on both sides of both the direction and the axial direction of the full compliance of the contact force, in order to consume at the same time, to maintain the ability of compliance by one path Directional compliance is achieved by pushing on a pivotable axis. The shaft is pushed by a spring. This is an axial compliance mechanism, in which the moving scroll is discharged axially and pushed towards the static scroll, so as to reach the top between the scrolls, and only a radial seal is found. Such a radially compliant mechanism is not practical because of the axis of rotation, and is not suitable for practical applications, especially in rotation per minute. Both the “difficult working environment and the high horsepower load” in the shrinkage machine require stronger connection devices than the Ondan ring (01 dham R ng) widely used in scroll air-conditioning compressors and sprayers. U.S. Patent No. 3,802,80Q provides a strong and reliable mechanism to prevent rotation. This mechanism limits the radial compliance movement of the movable scroll and thus the tangential seal of the air cavity formed between the coils. . The disadvantages of the above-mentioned prior patents are that the present invention discloses a structured scroll type fluid displacement device. Double helical sidewall. In the scroll scroll 1 scroll ^ Erliang, Zi's dynamic equilibrium. The moving scroll is in the radial direction and is semi-compliant, and the minimum connection between the scrolls is maintained: high efficiency, low friction, and low energy loss A are maintained during rotation to a good sealed state. The radial direction of the double-moving scroll is realized by a sliding joint and / or peripheral crankshaft-sliding joint machine 200304982 V. Description of the invention (4). A synchronizer ring is used to synchronize the azimuth of the surrounding crankshaft to avoid the mechanism from getting stuck during startup and operation. Depending on the compression ratio, workflow and other application requirements, scroll devices can be designed as one or more stages. One of the objectives of the present invention is to provide an improved scroll-type volumetric body displacement device 'in which a plurality of peripheral crankshafts are used to ensure the circular translation of the movable scroll relative to the static scroll, that is, the movement of the road And prevent the scroll from rotating. At the same time, by keeping the surrounding crankshafts synchronized, the scroll device avoids possible jamming of the crankshafts, so that the movable scroll can freely adjust its orbital motion radius, so as to achieve the compliance movement of the static scroll elements. Another object of the present invention is to provide an improved scroll-type device. The spiral element of the movable scroll is extended by 12 ΐ 丄 from the opposite end surfaces of the end plate, which is a so-called double-moving scroll. The two sides of the end plate of the double-moving scroll are similar or identical in mechanics, that is, the pressure gas is added to the double cavity, and the axial compliance mechanism pushes one coil in the axial direction. To another paired with Dendrobium, Fengyan a plus r is still controlled just enough to overcome the reaction force to ensure that the 2 push-knife breaks the instrument to contact, thereby serving the radial seal. Rarely.倂 7 orbiting scroll is in a "floating" state. [Embodiment] Here is a list of preferred embodiments and cooperation. To make the present invention more clear and detailed, 8 $ 8 pages 200304982 V. Description of the invention (5) The following! The technical features of the present invention will be described with reference to FIG.- FIG. Compression is applied to a scroll-type air main shaft 40 of the present invention, which is composed of two external bearings: a front casing 20 and a rear casing 21. ) And around the axis S1-S1y2 "is driven by an external mechanism (none of which is shown in the figure protruding from the end. Its t mandrel 2 2. s: the front distance of the driving crank pin 42 from the main shaft 40 is the second vortex; The two orbiting scrolls 60 are relative to the first and second Uor. The orbiting radius refers to the circular translational movement of the second orbital circle radius Y, the scroll 50 and the third scroll 70-vortex ΪΓΪ5ί) (also (Referred to as the front static scroll) has an end plate 51. The first main shaft 2 =: 2 extends out. In the middle of the end plate 51, there is a -hole I 4 0 extending through this hole to drive the second scroll 6. The f two scroll 60 (also referred to as a movable scroll) includes circular end plates "and", 屮 f 70 pieces 62 and 62, respectively, extending from opposite end faces of the end plates 61 and 61, and orbiting the bearing seat 63 and 63, fixed to the middle of the end plates 61 and 61, respectively

. For simplicity, the end plate 61, scroll element 62, and bearing block & J are called forward moving scrolls, while the end plate 61, element 62, and bearing block 63 are included, and the part is called rear moving scroll. volume. The moving scroll 60 includes a forward moving scroll and a backward moving scroll in a back-to-back position, and is called a double-moving scroll or a double-scroll. The forward and backward scrolls in the double scroll make orbital movements together, and at the same time, they can make radial relative movements during operation. < The third scroll 70 (also referred to as a rear static scroll) has an end plate 71, and a scroll_piece 72 extends from its front end. The scroll elements 52 and 62 and 62, ^ 2 are meshed with each other, and maintain a phase angular displacement of 180 ° and the &

Page 9 200304982 V. Description of the invention (6) Radial displacement of orbiting radius. At least one sealed air chamber is formed between the scroll elements 52 and 62 and the end plates 51 and 61. The same applies between the scroll elements 62, and 72 and the end plates 6 1 'and 71. The working fluid enters the compressor 10 through the air inlet 80 and the air inlet passage 81. The non-intake passage 81 is formed between the front case 20, the rear case 21, and the scroll as shown in FIG. The working fluid is sucked into the compressed air chamber formed between the scrolls, and is compressed by the guiding motion of the scroll, and is finally exhausted by the channels 82, 83 and the middle of the end plate 71 of the rear f scroll The port 84 is discharged. The shaft seal 22 is located in the shaft seal groove 23 on the first end plate 51 and seals the exhaust gas in the compressor so as not to leak to the external environment. Referring to Figures 1-5, the drive, rotation prevention and radial compliance mechanisms will be explained below. The driving crank pin 42 of the main shaft 40 passes through driving joints 64 and 64, and driving crank pin bearings 65 and 65, respectively, in the middle of the movable scroll 60, thereby driving the movable scroll 60. There are three pairs of peripheral extensions on the periphery of the moving scroll 60, which are 160a, 160b, and 160c extending from the end plate 61 and f, respectively, from the end plate 61. + We only extend the extensions 160a and 160, a, and The functions of related parts are described. The other two similar structures are self-evident. 3, There are 3 bearing holes 1613, 1611), 161 (: Figure week = shaft 162a is supported by two bearings 1633 and 164 & free at the front casing 20. Curve = pin 165a extends from the surrounding crankshaft coffee Peripheral crankshaft. The distance between the line a and the axis line S2a of the crank pin 165a is equal to the orbiting half. "Peripheral crankshaft bearings 16 7 a and 16 7 a are installed in 2003. (7)

The peripheral crankshaft 162a passes through the crankpin 165a, the peripheral crankshaft joints 168a and 168'a ', and then passes through the crankshaft bearings 167a and 167, a, and the other two pairs of peripheral crankshafts 1 6 2 b and 1 6 2 c together with corresponding parts The orbiting scroll 60 is moved to prevent the rotation. Referring to Fig. 7, a slot 190 is formed in the front drive joint 64. As shown in Figs. The driving crank pin 42 is located in the groove go go. The groove 190 is slightly longer in the radial direction than the driving crank pin 42. When the driving crank pin 42 rotates counterclockwise as shown by arrow B in the figure, the driving plane 191 of the crank pin 42 pushes the sliding plane 192 of the front drive joint 64. The above description also applies to the rear drive gate 64 and its related parts. Referring to Figs. 1, 7 and 8, when the shaft 40 rotates, the orbits of the orbiting scroll 60 and the orbiting scroll are subjected to centrifugal forces Fco and F'c0 generated by their orbital motion, respectively. In addition to the movement of the track, the front and rear moving scrolls of the moving scroll 60 will be driven by the joints 64 and 64, and the surrounding crankshaft joints 168a, 168, a, 168b, l68, b, 168cand 168'c moves radially together as shown by arrow c in FIG. 7 until the movable scroll element and its corresponding static scroll element make side-to-side contact. Toward compliance mechanism. Sliding compliance is well known in the past. But because it is reused in the design of the double scroll structure as we have described in the background above. The orientation of its crankshaft ensures that the orbiting scroll can work without getting stuck. An example of the present invention provides a sliding motion of a sliding joint and a peripheral crankshaft synchronizer. Referring to Figures 1-5, the lower joint-crankshaft mechanism achieves radial technical difficulties. This mechanism, as pointed out in the Gu analysis, has never been difficult in terms of how to coordinate peripheral orbital movement and freely move in the radial direction. Provides a mechanism including the surrounding crankshaft, so that the movable scroll can be used as a radial surface to explain the function of the synchronizing ring 170

200304982 V. Description of the invention (8) In Figure 4, the line segments Sla — S2a, S1 b — S2b, S1 c — S2c represent the centers of the surrounding crankshafts 162a, 162b, and 162c, SI a, Sib, and Sic and their corresponding crankshafts. The center of the pins 165a, 165b, and 165c, S2a, S2b and A2c connected line segment _ a line or stop state, line segment Sla — S2a, S 1 b — S2b, SI c — S2c must always remain parallel to each other, also Is in a synchronized state. Otherwise, due to the radial and tangential freedom of movement of each peripheral crankshaft, these peripheral crankshafts 162a, 162b, and 162c, the drive shaft 40, and even the movable scroll 60 may be stuck during startup or operation. . In order to keep the peripheral crankshafts in sync ', as shown in Figure 1-5, the synchronizer ring 170 is connected to the peripheral crankpins 165a, 165b, and 165 (: through synchronizer ring bearings 171a, 171b, and 171c, respectively. The synchronizer ring works and moves Scroll-like circular translation, that is, the movement of the road, so that the three peripheral crank pins are in a triangular relationship, that is, kept synchronized, so that the line segment 813-S2a, slb_S2b, Slc-S2C. At any time Keep parallel to each other. Now let's look back at the moving scroll 60 subject to the centrifugal forces FC0 and F'co. See figure! And Figure 4, the centrifugal forces Fco and F'co are partially balanced by the weights 90 and 91 and 9 〇, and ", the resultant force of the balanced" remaining centrifugal "force is just enough to overcome the radial separation force generated by the compressed fluid. During the operation of the device, because the line segments Sla-S2a and sib-S2b'Sic-S2c remain synchronized Under the action of centrifugal force, the orbiting scroll can move to the direction, that is, with the line segment 仏 _ 仏, slb-S2b, sic_s2c: 亍 direction to the orbiting scroll elements 6 2 and 6 2, respectively, with 'non⑦t's Contact to reach the scroll Press

V. Description of the invention (9) Tangential seal between air deflation chambers. The complete balance of the centrifugal force experienced by the scroll and the participation of other balance weights are traditional methods, and will not be described in detail here. Referring to Figs. 1 and 4, the axial compliance mechanism of the double scroll structure will be described in detail below. The movable scroll 60 includes a front end plate 61 and a rear end plate 61 ′. An air chamber 67 is formed between the two end plates. The seal 68 isolates the air chamber 67 from the air path 81 and the suction chamber. When activated, the elastic force of the seal 68 pushes the front and rear static scrolls forward and backward, respectively, and maintains a light contact between the front end and the bottom of the scroll. The pressure chamber 67 is connected to the exhaust gas through the channels 82 and 83. The surface areas of the surfaces 85 and 85 'are designed so that the axial forces generated by the high-pressure gas acting on them slightly exceed the corresponding surfaces 69 and 69' and the scroll elements acting on the end plates 61 and 61, respectively. 62 and 62, the sum of the gas axial forces at the top of the gas. The resultant force of the axial forces will respectively push the front and rear moving scrolls to move in the axial direction to the corresponding front and rear static scrolls, so that the relevant 6 pairs of contact surfaces report slight contact. The six pairs of contact surfaces include the contact surfaces of the top surfaces of two pairs of movable scrolls and the corresponding bottom surfaces of the static scrolls. It also includes the contact surfaces of the top and bottom surfaces of the other two pairs of static scrolls and the corresponding bottom surfaces of the movable scrolls. The remaining two pairs of contact surfaces are the contact surfaces between the thrust bearing surfaces 5 9 and 7 9 of the front and rear housings and the thrust bearing surfaces 6 9 and 6 9 ′ of the front and rear movable scrolls, respectively. The supporting surfaces 59 and 69 respectively support the surfaces 69 and 69 of the movable scroll, thereby avoiding the wobble of the movable scroll. The contact between the six pairs of surfaces described above does not necessarily occur at the same time during assembly, but after the break-in, all six pairs of contact surfaces will have slight contact. The described axial compliance mechanism enables good radial reach and sealing between the compression chambers and minimizes wear and tear on the dynamic and static coils, and is self-compensating.

Page 13 200304982 V. Description of the invention (ίο) The past technology proposed many axial compliance mechanisms, many of which can be transplanted and applied to the present invention. Figures q and 10 depict another example of a synchronizer for a radially compliant double scroll structure. In these two figures, those corresponding to those in Figs. 1 to 8 are represented by the same digits. In this example, three peripheral crankshaft timing pulleys 173a, 173b, and 173c are fastened to the peripheral crankshafts 162a, 162b, and 162c, respectively. The timing belt 174 links the three timing pulleys 1 7 3 a ′ 1 7 3 b and 1 7 3 c and keeps them in sync, that is, the center of the peripheral crankshafts 162a, 162b, and 162c, SI a,

The centers of Sib and Sic and the surrounding crankpins 165a, 165b and 165c, and the line segments S2a, S2b 'S2, c of Sla-S2a, Sib-S2b, Sic-S2c. Keep them parallel. The tensioning pulley 175 keeps the timing belt 174 in its normal position and maintains the proper tension for smooth operation. There are many mechanisms such as gears, etc., as long as they can make the line segments s j a, sib — S2b, Sic — S2c keep the parallel relationship between each other in the scroll device whether it is running or stopped, and they can be used as synchronizers. Figures 11 and 12 illustrate another example of a shaft mechanism that prevents rotation and is used in a winding device. Corresponding to this element is the use of rotation. The crank pin 42 drives the orbiting scroll 60 in a counterclockwise direction by using an ondane ring instead of the above-mentioned peripheral curved coupling mechanism, and is used in the suspension scroll example. The same digits as in FIGS. 1 to 10 are indicated. When the crankshafts 64 and 64, the drive bearings 65 and 65, translate circularly, that is, orbital motion. Ondan
