(Japanese Laid-Open Patent Publication No. 2007-247526 and Japanese Patent Application Publication No. Hei 8-276508)
習知之該種密封環係將圓筒狀之PTFE材料，首先進行機械的切圓，接著藉由切削、研磨切削、切斷加工等的機械加工，以進行製造。因此，習知之物具有需要機械加工等的加工工程次數，且亦多產生材料的損失，及製造成本高的缺點。另一方面，雖然射出成形的製造亦屬可能，然而其場合，開口部將產生斜切，而在接合斜切時，密封環無法形成正圓，因此密封性有不足之可能。 This type of seal ring is a cylindrical PTFE material which is first mechanically tangentially wound and then machined by cutting, grinding, cutting, or the like. Therefore, conventional materials have a number of processing operations requiring mechanical processing, etc., and also cause a large loss of materials and a disadvantage of high manufacturing cost. On the other hand, although it is possible to manufacture the injection molding, in this case, the opening portion is chamfered, and when the bevel is joined, the sealing ring cannot form a perfect circle, and thus the sealing property may be insufficient.
於是，本發明的密封環，其係在圓周一處具有缺口之圓環狀的整體形狀，且包含環本體及由該環本體之第一端部、第二端部向圓周方向延伸狀附設的第一凸部、第二凸部；該缺口係以熱可塑性樹脂組成物一體成形為開口狀態的圓環狀整體形狀，於該開口狀態之該環本體1係相對該缺口之中央點，在180°±30°之範圍內，曲率半徑係存在著最大尺寸之部 位，且設定為由該最大尺寸之部位朝向各該第一端部、第二端部，形成隨著越接近圓周方向，曲率半徑逐漸減少，使該第一端部、該第二端部的曲率半徑係形成最小尺寸，該第一凸部與第二凸部係在相互重疊之缺口關閉狀態下，整體形狀係形成正圓形的構成。 Therefore, the seal ring of the present invention has an annular overall shape having a notch at one circumference, and includes a ring body and a first end portion and a second end portion of the ring body extending in a circumferential direction. a first convex portion and a second convex portion; the notch is an annular overall shape in which the thermoplastic resin composition is integrally formed into an open state, and the ring body 1 in the open state is opposite to a center point of the notch at 180 In the range of ±30°, the radius of curvature is the portion having the largest dimension, and is set to be the portion of the largest dimension toward each of the first end portion and the second end portion, and the radius of curvature is formed as it approaches the circumferential direction. Gradually decreasing, the radius of curvature of the first end portion and the second end portion is formed to a minimum size , and the first convex portion and the second convex portion are in a closed state in which the mutually overlapping notches are closed, and the overall shape is formed into a perfect circle. Composition.
再者，使用該熱可塑性樹脂組成物之彎曲彈性率係1500MPa以上、6000MPa以下的樹脂組成物。再者，使朝對方部件之二接觸面之表面之算術平均粗度設定為0.1以上、2以下。 Further, the thermoplastic composition of the thermoplastic resin composition is a resin composition of 1500 MPa or more and 6000 MPa or less. Further, the arithmetic mean roughness of the surfaces of the two contact faces facing the counterpart member is set to be 0.1 or more and 2 or less.
再者，該環本體之橫剖面形狀係矩形狀，且該第一凸部與第二凸部係由分離線使該環本體之矩形狀的横剖面分割為二的橫剖面形狀；在該第一凸部與第二凸部相互重疊的缺口關閉狀態下，該第一凸部與第二凸部之二對應面相互間係具有間隙。 Furthermore, the cross-sectional shape of the ring body is rectangular, and the first convex portion and the second convex portion are divided into two cross-sectional shapes by a separation line to divide the rectangular cross section of the ring body; When the notch and the second convex portion overlap each other, the two corresponding surfaces of the first convex portion and the second convex portion have a gap therebetween.

為讓本發明之上述及其他目的，特徵及優點能更明顯易懂，下文特舉本發明之較佳實施例，作詳細說明如下： 如第3圖~第6圖所示，相關本發明之密封環S係形成在圓周一處具有缺口5之圓環狀的整體形狀。而且，該密封環S係包含佔有比360°僅稍小之中心角度的環本體1，及由該環本體1之第一端部11、第二端部12向圓周方向延伸狀附設的第一凸部21、第二凸部22。第1圖及第2圖中揭示使用狀態，例示適用於空調器用之壓縮機2的渦旋式壓縮機構3之場合。 The above and other objects, features and advantages of the present invention will become more <RTIgt; As shown in Figs. 3 to 6, the seal ring S according to the present invention is formed in an annular overall shape having a notch 5 at one circumference. Further, the seal ring S includes a ring body 1 that occupies a center angle slightly smaller than 360°, and a first one that is extended in the circumferential direction by the first end portion 11 and the second end portion 12 of the ring body 1. The convex portion 21 and the second convex portion 22. The use state is shown in Figs. 1 and 2, and the case where the scroll compression mechanism 3 of the compressor 2 for an air conditioner is applied is exemplified.
渦旋式壓縮機構3主要係由緊貼外罩4及外罩4上方所配置之固定渦捲6，及嚙合該固定渦捲6之可動渦捲7等所構成。外罩4上，在與可動渦捲7之下面(背面)7A相向之平面部4A凹設密封槽4B，於該密封槽4B中裝入本發明之密封環S。該密封環S係密封(封閉)可動渦捲7之背面7A及外罩4之平面部4A，以形成背壓空間。再者，第2圖係第1圖之Y部的擴大圖。 The scroll compression mechanism 3 is mainly composed of a fixed scroll 6 disposed above the outer cover 4 and the outer cover 4, a movable scroll 7 that engages the fixed scroll 6, and the like. In the outer cover 4, a seal groove 4B is recessed in a flat portion 4A facing the lower surface (back surface) 7A of the movable scroll 7, and the seal ring S of the present invention is incorporated in the seal groove 4B. The seal ring S seals (closes) the back surface 7A of the movable scroll 7 and the flat portion 4A of the outer cover 4 to form a back pressure space. In addition, Fig. 2 is an enlarged view of the Y portion of Fig. 1 .
而且，如第3圖~第6圖所示，缺口5係以熱可塑性樹脂組成物，一體成形為開口狀態的整體形狀。第3圖中，箭頭F係揭示射出成形時之熔融樹脂的注入方向，符號10係注入澆口痕跡部，雖可藉由刀刃盡可能漂亮的切斷，惟亦有餘留形成微小突出部之虞，因此亦可進行最後潤飾之研磨切削等的機械加工。然而，除了如此之注入澆口痕跡部10以外，可省略機械加工，以形成射出成形面。 Further, as shown in FIGS. 3 to 6, the notch 5 is formed of a thermoplastic resin composition and integrally molded into an overall shape in an open state. In Fig. 3, the arrow F reveals the injection direction of the molten resin at the time of injection molding, and the symbol 10 is injected into the gate trace portion. However, the blade can be cut as beautifully as possible, but the remaining portion is formed. Therefore, it is also possible to perform machining such as grinding and cutting of the final finishing. However, in addition to the injection of the gate trace portion 10, machining may be omitted to form an injection molding surface.
作為射出成形本發明之密封環S較佳的熱可塑性樹脂組成物，可列舉PES樹脂組成物。由於射出成形品有較難產生所謂之毛邊的優點，又由於熱膨脹率低由金屬模取出後之收縮性低，密封環S之尺寸亦可維持高的精確度，因此有可省略前述機械加工的優點。 A preferred thermoplastic resin composition for injection molding of the seal ring S of the present invention is a PES resin composition. Since the injection molded article has an advantage that it is difficult to produce a so-called burr, and the shrinkage property after removal of the metal mold is low due to a low coefficient of thermal expansion, the size of the seal ring S can also maintain high precision, so that the aforementioned machining can be omitted. advantage.
而且，如第3圖所示，雖然缺口5係在開口狀態的整體形狀，由PES樹脂組成物等的熱可塑性樹脂組成物而形成一體，然而由射出金屬模所取出之缺口5為開口狀態之密封環S的環本體1，其係在與缺口5之 相反側具有曲率半徑R13係最大尺寸之部位13，且設定為由該最大尺寸之部位13朝向各第一端部11、第二端部12，形成隨著越接近圓周方向M1、M2，曲率半徑R1、R2逐漸減少，且第一端部11、第二端部12之曲率半徑R11、R12係形成最小尺寸；再者，小的突出尺寸之第一凸部21、第二凸部22之外周面的曲率半徑係與上述R11、R12相同。再者，如第3圖所示，上述曲率半徑R13、R1、R2、R11、R12係由中心點O1至環本體1之外周面為止的尺寸。 Further, as shown in Fig. 3, the notch 5 is integrally formed in the open state, and is integrally formed of a thermoplastic resin composition such as a PES resin composition. However, the notch 5 taken out by the injection mold is in an open state. The ring body 1 of the seal ring S has a portion 13 having a maximum radius of curvature R 13 on the opposite side of the notch 5, and is set to face the first end portion 11 and the second end from the portion 13 of the maximum size. The portion 12 is formed to gradually decrease in radius of curvature R 1 , R 2 as it approaches the circumferential direction M 1 , M 2 , and the radius of curvature R 11 , R 12 of the first end portion 11 and the second end portion 12 form a minimum size. Further, the radius of curvature of the outer peripheral surface of the first convex portion 21 and the second convex portion 22 having a small protruding size is the same as that of the above-described R 11 and R 12 . Further, as shown in Fig. 3, the curvature radii R 13 , R 1 , R 2 , R 11 , and R 12 are the dimensions from the center point O 1 to the outer circumferential surface of the ring main body 1.
再者，就上述最大尺寸之部位13追加說明，第3圖中，開口狀態之環本體1係相對缺口5之中央之點(中心點)P5，在180°±30°之範圍內存在著最大尺寸之部位13。即，第3圖所示之θ係30°，在2θ=60°之範圍內配設最大尺寸之部位13。該最大尺寸之部位13的中心角度，係只要選擇在1°~60°的範圍內即可。再者，第3圖中，L0係揭示包含中心點P5之直徑的線。 Further, the above-mentioned maximum size portion 13 will be additionally described. In the third diagram, the ring body 1 in the open state is located at a point (center point) P 5 with respect to the center of the notch 5, and exists within a range of 180° ± 30°. The largest size part 13. That is, the θ shown in Fig. 3 is 30°, and the portion 13 having the largest size is disposed in the range of 2θ = 60°. The center angle of the portion 13 of the largest size is selected to be in the range of 1 to 60 degrees. Further, in Fig. 3, L 0 reveals a line including the diameter of the center point P 5 .
如此的，金屬模之模穴之形狀、尺寸及由其所取出之密封環S(參照第3圖)，其外周緣形狀係在相對缺口5之180°相反側之±θ(=±30°)的範圍內，配設曲率半徑R13為最大尺寸之部位13，且設定為由該部位13朝向缺口5逐漸減少之非正圓形。於使用狀態下，即如第2圖所示之裝著在密封槽4B之狀態下，雖然第一凸部21與第二凸部22係相互重疊形成缺口關閉狀態，然而在缺口開口狀態下，藉由上述之非正圓形，且隨著彈性變形，由中心點O1形成相同半徑R0之正圓形，而相對第2圖所示之密封槽4B之徑向方向外側的內壁面緊密的接觸。由缺口開口狀態(第3圖)往缺口關閉狀態(第7圖)變形之際，將變形為最大尺寸之部位13係最大且曲率半徑係減少，且第一端部11、第二端部12係幾乎不會變形。因此，第7圖所示之上述曲率半徑R0，其係形成與第3圖所示之第一端部11、第二端部12之曲率半徑R11、R12相等。 Thus, the shape and size of the cavity of the metal mold and the seal ring S (refer to FIG. 3) taken out therefrom have an outer peripheral shape of ±θ (=±30°) on the opposite side of 180° with respect to the notch 5. In the range of the range, the portion 13 having the radius of curvature R 13 is the largest size, and is set to a non-circular shape in which the portion 13 gradually decreases toward the notch 5. In the state of use, that is, in the state in which the sealing groove 4B is attached as shown in FIG. 2, the first convex portion 21 and the second convex portion 22 are overlapped with each other to form a notched closed state, but in the notched opening state, By the above-mentioned non-asymmetric circle, and with the elastic deformation, a perfect circle having the same radius R 0 is formed from the center point O 1 , and the inner wall surface on the outer side in the radial direction of the seal groove 4B shown in FIG. 2 is tight. s contact. When the notch opening state (Fig. 3) is deformed toward the notch closed state (Fig. 7), the portion 13 deformed to the maximum size is the largest and the radius of curvature is reduced, and the first end portion 11 and the second end portion 12 are 12 The system will hardly deform. Therefore, the radius of curvature R 0 shown in Fig. 7 is formed to be equal to the curvature radii R 11 and R 12 of the first end portion 11 and the second end portion 12 shown in Fig. 3 .
環本體1之橫剖面形狀係矩形狀。本發明中，所謂的「矩形狀」，當然係包含第2圖所示之正方形、長方形，甚至包含如第11圖所示之由基本矩形G藉由傾斜狀直線L15去掉一角部15之形狀，而且亦可定義為包含正方形或長方形之四個角部中的至少一個具有小圓角部之形狀。於第2圖所示之使用狀態中，包含接觸可動渦捲7之背面7A等的(可動側)被密封平面P1的第一接觸面26，及接觸密封槽4B之內壁面14等的(固定側)被密封內周面P2的第二接觸面27。在由垂直狀之被密封平面P1、被密封內周面P2所形成之角落部8，其於受壓時係被按壓。 The cross-sectional shape of the ring body 1 is rectangular. In the present invention, the term "rectangular" includes, of course, a square or a rectangle as shown in Fig. 2, and even includes a shape in which a corner portion 15 is removed by a substantially rectangular G by a slanted straight line L 15 as shown in Fig. 11. And may also be defined as a shape in which at least one of the four corners including a square or a rectangle has a small rounded portion. In the usage state shown in FIG. 2, comprising contacting the movable scroll 7 and the like of the back surface 7A (movable side) of the inner wall surface of the sealing plane P 1 of the first contact surface 26, and the contact 4B of the seal groove 14 and the like ( The fixed side) is sealed with the second contact surface 27 of the inner peripheral surface P 2 . The corner portion 8 formed by the vertically sealed plane P 1 and the sealed inner peripheral surface P 2 is pressed when pressed.
可是，即使本發明係藉由採用PES樹脂組成物等的熱可塑性樹脂組成物，使橫剖面形成如第2圖等所示之正方形、長方形(省略去角)，在渦捲運動中密封環S之一角部15，其係具有於背面7A與平面部4A之間隙中不會產生嚙入等不良狀態的優點。惟，考量壓力、溫度、運動速度與作動方向等、及流體的特性等使用條件係過於苛刻的場合，亦有較佳形成如第11圖等所示之去角部16的情況。就該去角部16之橫剖面形狀追加說明的話，則如第11圖所示，藉由傾斜狀直線L15由二點鏈線所示之基本矩形G去掉一角部15(第11圖中係以G去角為實例)。 However, even in the present invention, by using a thermoplastic resin composition such as a PES resin composition, a cross section is formed into a square shape or a rectangular shape (omitted chamfering) as shown in Fig. 2 and the like, and the seal ring S is formed in the wrap motion. One of the corner portions 15 has an advantage that no trouble occurs in the gap between the back surface 7A and the flat portion 4A. However, in the case where the conditions of use such as pressure, temperature, moving speed, direction of action, and the characteristics of the fluid are too severe, it is preferable to form the chamfered portion 16 as shown in Fig. 11 and the like.

Further, in the drawings of FIGS. 16A and 16B, the cross-sectional shape of the second convex portion 22 is a right-angled equilateral triangle shape, and preferably, the cross-sectional shape may be formed as shown in FIGS. 16C and 16D. Triangular shape. As described above, in the 16A, 16B, 16C, and 16D drawings, the two corresponding surfaces 23 and 24 are straight lines (in the cross-sectional shape). Furthermore, in the embodiment shown in FIG. 16E, the cross-sectional shape of the first convex portion 21 is formed by cutting a rectangular or square cutout portion 16A at one corner, and the second convex portion 22 is formed to be fitted. The rectangular or square cross-sectional shape of the cutout portion 16A is formed, and the two corresponding surfaces 23 and 24 are formed in a L-shaped cross section. Furthermore, in the embodiment shown in FIG. 16F, the cross-sectional shape of the first convex portion 21 is formed by cutting a concave concave portion 16B of a quarter circle or the like at a corner portion, and the second convex portion is formed.

Alternatively, the small rounded portion 35 and the arcuate recessed portion 34 as shown in Fig. 14C or Fig. 14D may be preferably formed at the right angle top of the second convex portion 22 of each of the sixteenth embodiments. .
而且，如第7~10圖所示，在第一凸部21及第二凸部22相互重疊之缺口關閉狀態下，將第一凸部21及第二凸部22之橫剖面各部尺寸設定在不會由第11圖所示之基本矩形G超出範圍的尺寸公差。相對於沿著第12A圖所示之分離線L21之傾斜狀的對應面23的徑向尺寸H23、軸向尺寸T23(參照第12B圖)，將沿著第12A圖所示之分離線L21之傾斜狀的對應面24的徑向尺寸H24、軸向尺寸T24設定為相同或僅微小。即，在第一凸部21及第二凸部22相互重疊之缺口關閉狀態下，使相互重疊之第一凸部21、第二凸部22之接觸面26、27形成與基本矩形G一致之場合，則將第一凸部21及第二凸部22之剖面形狀及尺寸設定為在二對應面23、24相互間形成間隙(參照第14、15、16圖)。 Further, as shown in FIGS. 7 to 10, in the state in which the first convex portion 21 and the second convex portion 22 overlap each other, the cross-sectional portions of the first convex portion 21 and the second convex portion 22 are set to each other in size. The dimensional tolerance of the basic rectangle G not shown in Fig. 11 is out of range. The radial dimension H 23 and the axial dimension T 23 (refer to FIG. 12B) of the inclined corresponding surface 23 along the separation line L 21 shown in FIG. 12A will be divided as shown in FIG. 12A. The radial dimension H 24 and the axial dimension T 24 of the inclined counterpart surface 24 of the offline line L 21 are set to be the same or only minute. That is, in the closed state in which the first convex portion 21 and the second convex portion 22 overlap each other, the contact faces 26 and 27 of the first convex portion 21 and the second convex portion 22 which are overlapped each other are formed to conform to the substantially rectangular G. In this case, the cross-sectional shape and size of the first convex portion 21 and the second convex portion 22 are set such that a gap is formed between the two corresponding surfaces 23 and 24 (see FIGS. 14, 15, and 16).
本發明中，由於係藉由熱可塑性樹脂組成物之射出成形而可製造，因此可如同H24≦H23、T24≦T23一般的容易設定尺寸公差(於金屬模之模穴的階段)。第17圖或第18圖係揭示假設設定為H24>H23、T24>T23之場合，而產生不良狀態之說明圖。即，於使用狀態下，環本體S係在由被密封平面P1及被密封內周面P2所形成之角落部8被按壓，此時第二凸部22係緊密接觸二面P1、P2，而第一凸部21係僅抵接其中一面，而產生外部漏洩間隙K1、K2，且在箭頭M10、M20方向產生流體漏洩。 In the present invention, since it can be produced by injection molding of a thermoplastic resin composition, it is easy to set dimensional tolerances like H 24 ≦H 23 and T 24 ≦T 23 (in the stage of the mold of the metal mold). . Fig. 17 or Fig. 18 is an explanatory diagram showing a case where a failure state is set assuming that H 24 > H 23 and T 24 > T 23 are set . That is, in the use state, the ring body S is pressed by the corner portion 8 formed by the sealed plane P 1 and the sealed inner peripheral surface P 2 , and at this time, the second convex portion 22 is in close contact with the two faces P 1 , P 2 , and the first convex portion 21 abuts only one of the surfaces, and generates external leakage gaps K 1 , K 2 , and fluid leakage occurs in the directions of arrows M 10 and M 20 .
本發明中，可藉由形成如前述的設定為H24≦H23、T24≦T23，且在第一凸部21及第二凸部22相互重疊之缺口關閉狀態不會由基本矩形G超出範圍，並在二對應面23、24存在著間隙之構成，而可防止如同第17、18圖所示之不良狀態。甚至，如第15圖所示，將第一凸部21及第二凸部22形成與第11圖之基本矩形G之四邊重疊(一致)之場合，則沿著分離線L21之二對應面，即對應面23及對應面24之間隙尺寸ε將形成最大，且較佳將其最大間隙尺寸ε0設定在10μm以上、100μm以下。即，較佳形成10μm≦ε0≦100μm。當超越上限值，則流體漏洩將會急劇增加。 In the present invention, the gap can be closed by the formation of H 24 ≦H 23 , T 24 ≦T 23 as described above, and the first convex portion 21 and the second convex portion 22 overlap each other without being substantially rectangular G Exceeding the range, and having a gap between the two corresponding faces 23 and 24, it is possible to prevent a bad state as shown in Figs. Further, as shown in Fig. 15, when the first convex portion 21 and the second convex portion 22 are formed to overlap (consistent) with the four sides of the basic rectangle G of Fig. 11, the second corresponding surface along the separation line L 21 That is, the gap size ε of the corresponding surface 23 and the corresponding surface 24 is maximized, and the maximum gap size ε0 is preferably set to be 10 μm or more and 100 μm or less. That is, it is preferable to form 10 μm ≦ ε 0 ≦ 100 μm. When the upper limit is exceeded, the fluid leakage will increase dramatically.
如此的，在缺口關閉狀態下，且在使第一凸部21及第二凸部22與基本矩形G之四邊重疊，沿著分離線L21之二對應面23、24之間隙尺寸ε形成最大之狀態下，由於係將最大間隙尺寸ε0設定在10μm以上且100μm以下，因此可抑制來自二對應面23、24漏洩，且第一凸部21及第二凸部22不會由基本矩形G超出，而可更進一層的提昇密封性能。 Thus, in the gap closed state, and the first convex portion 21 and the second convex portion 22 are overlapped with the four sides of the basic rectangle G, the gap size ε along the two corresponding faces 23, 24 of the separation line L 21 is maximized. In this state, since the maximum gap size ε0 is set to 10 μm or more and 100 μm or less, leakage from the two corresponding faces 23 and 24 can be suppressed, and the first convex portion 21 and the second convex portion 22 are not exceeded by the basic rectangular G. , but can further improve the sealing performance.
再回到第2圖加以說明，由於可動渦捲7係進行渦捲運動，因此二接觸面26、27係往對方部件被密封平面P1、被密封內周面P2接觸(壓接)。而且，由第3~10圖亦可明顯得知，第一凸部21及第二凸部22亦以連續面，而形成二接觸面26、27。本發明中，該二接觸面26、27亦如前述係省略了機械加工之射出成形之原來的樣子，且係將以JIS B 0601為標準所測量之其表面之算術平均粗度(Ra)設定為0.1~2，而可發揮優良的密封性能及抗磨耗性。再者，作為射出成形所需要之熱可塑性樹脂組成物，只要彎曲彈性率係1500MPa以上、6000MPa以下之物即可，例如聚碸系樹脂組成物，具體而言較佳係PES(聚醚)樹脂組成物、PSU(聚碸)樹脂組成物、PPSU(聚苯碸)樹脂組成物。特別，較佳彎曲彈性率係2000MPa以上、4000MPa以下。 Referring back to Fig. 2, since the movable scroll 7 is subjected to the wrap motion, the two contact faces 26 and 27 are brought into contact with each other by the sealing plane P 1 and the sealed inner peripheral surface P 2 (pressure-bonded). Further, as is apparent from the third to tenth views, the first convex portion 21 and the second convex portion 22 also have continuous faces to form the two contact faces 26 and 27. In the present invention, the two contact faces 26 and 27 also omits the original appearance of the mechanical injection molding as described above, and the arithmetic mean roughness (Ra) of the surface measured by JIS B 0601 is set. It is 0.1~2, and it can exert excellent sealing performance and abrasion resistance. In addition, the thermoplastic resin composition required for the injection molding may be a material having a flexural modulus of 1500 MPa or more and 6000 MPa or less. For example, a polyfluorene-based resin composition, specifically, a PES (polyether) resin is preferable. Composition, PSU (polyfluorene) resin composition, PPSU (polyphenyl hydrazine) resin composition. In particular, the bending elastic modulus is preferably 2000 MPa or more and 4,000 MPa or less.
再者，作為相關本發明之密封環之較佳的PES樹脂組成物，其係在PES樹脂中添加具有石墨粉末等之層狀結晶構造之化合物及/或氟樹脂粉末等的PES樹脂組成物。藉由如此之添加，可在上述彎曲彈性之範圍內容易的調整特性，且作為密封環之抗磨耗性佳，又耐熱、耐藥品性亦良好，具有充分的延伸性，且裝著性及密封性亦良好，而適用於第1圖所例示之空調器用壓縮機等。再者，作為其他熱可塑性樹脂組成物，可使用聚硫化芳撐(polyarylene sulfide)系樹脂組成物，具體而言在PPS(聚苯硫醚)樹脂組成物中添加上述具有石墨粉末等之層狀結晶構造之化合物、氟樹脂粉末、及/或玻璃纖維、碳素纖維等的纖維狀充填材料的PPS樹脂組成物 亦可適用。 Further, as a preferred PES resin composition of the seal ring of the present invention, a PES resin composition having a layered crystal structure such as graphite powder and/or a fluororesin powder is added to the PES resin. By such addition, the characteristics can be easily adjusted within the range of the above-mentioned bending elasticity, and the seal ring is excellent in abrasion resistance, heat resistance and chemical resistance, and has sufficient elongation, and is excellent in sealing and sealing. It is also suitable for the air conditioner compressor and the like illustrated in Fig. 1 . Further, as the other thermoplastic resin composition, a polyarylene sulfide-based resin composition can be used, and specifically, a layered graphite powder or the like is added to the PPS (polyphenylene sulfide) resin composition. A PPS resin composition of a crystalline structure compound, a fluororesin powder, and/or a fibrous filler such as glass fiber or carbon fiber Also applicable.
本發明中，由於缺口5係以熱可塑性樹脂組成物，一體成形為開口狀態的整體形狀，且除了熱可塑性樹脂組成物之注入澆口痕跡部10以外，可形成省略了機械加工之射出成形面，因此由平面觀之形成無重疊部位的形狀，且金屬模容易製造，甚至幾乎或可完全的省略機械加工，而可減少加工之工程次數，與習知需要切削或研磨切削之製造方法相較下，亦可減少材料的損失，並可降低製造成本，且密封性或抗磨耗性良好的密封環係可保持穩定的高品質，進行大量的生產。 In the present invention, the notch 5 is formed of a thermoplastic resin composition, and is integrally molded into an overall shape in an open state, and an injection molding surface in which mechanical processing is omitted can be formed in addition to the injection gate trace portion 10 of the thermoplastic resin composition. Therefore, the shape of the non-overlapping portion is formed by the plan view, and the metal mold is easy to manufacture, and the machining can be almost or completely omitted, and the number of times of processing can be reduced, compared with the conventional manufacturing method that requires cutting or grinding. In addition, the loss of material can be reduced, and the manufacturing cost can be reduced, and the sealing ring system with good sealing or abrasion resistance can maintain stable high quality and be mass-produced.
本發明係如上所述，由於密封環係形成在圓周一處具有缺口5之圓環狀的整體形狀，且包含環本體1及由該環本體1之第一端部11、第二端部12向圓周方向延伸狀附設的第一凸部21、第二凸部22；該缺口5係以熱可塑性樹脂組成物一體成形為開口狀態的圓環狀整體形狀，於該開口狀態之該環本體1係相對該缺口5之中央點P5，在180°±30°之範圍內，曲率半徑R13係存在著最大尺寸之部位13，且設定為由該最大尺寸之部位13朝向各該第一端部11、第二端部12，形成隨著越接近圓周方向M1、M2，曲率半徑R1、R2減少，該第一凸部21與第二凸部22係在相互重疊之缺口關閉狀態下，整體形狀係形成正圓形的構成；因此，即使金屬模容易製造之缺口5係在開口狀態，然而第一凸部21與第二凸部22係在相互重疊的使用狀態下，可形成正圓形，且相對圓形內周面發揮優良的密封性能(封閉性)。 The present invention is as described above, since the seal ring is formed in an annular overall shape having a notch 5 at one circumference, and includes the ring body 1 and the first end portion 11 and the second end portion 12 of the ring body 1 a first convex portion 21 and a second convex portion 22 which are extended in the circumferential direction; the notch 5 is an annular overall shape in which the thermoplastic resin composition is integrally formed into an open state, and the ring body 1 is in the open state. Relative to the center point P 5 of the notch 5, in the range of 180°±30°, the radius of curvature R 13 is the portion 13 having the largest dimension, and is set to be from the portion 13 of the largest dimension toward each of the first ends. The portion 11 and the second end portion 12 are formed to have a smaller radius of curvature R 1 and R 2 as they approach the circumferential directions M 1 and M 2 , and the first convex portion 21 and the second convex portion 22 are closed at mutually overlapping gaps. In the state in which the overall shape is formed into a perfect circular shape; therefore, even if the notch 5 in which the metal mold is easily manufactured is in an open state, the first convex portion 21 and the second convex portion 22 are in a state of being overlapped with each other, Forms a perfect circle and exhibits excellent sealing with respect to the circular inner peripheral surface (Closed).
再者，作為熱可塑性樹脂組成物，由於利用彎曲彈性率係1500MPa以上、6000MPa以下之熱可塑性樹脂組成物，因此具有充分的延伸性，作為密封環可發揮較佳的彈張力，且與對方面之接觸情況亦優良，而具有優秀的密封性能(封閉性)。而且，首次藉由射出成形，可達成耐熱性、耐藥品性、抗磨耗性優良之密封環的實用化。再者，由於使朝對方部 件之二接觸面26、27之表面之算術平均粗度Ra設定為0.1以上、2以下，因此可確保更優良的密封性能(封閉性)。 In addition, since the thermoplastic resin composition having a flexural modulus of 1500 MPa or more and 6000 MPa or less is used as the thermoplastic resin composition, it has sufficient stretchability, and can exhibit a preferable elastic tension as a seal ring, and the opposite aspect. The contact condition is also excellent, and has excellent sealing performance (closedness). Further, for the first time, by injection molding, it is possible to realize the practical use of a seal ring excellent in heat resistance, chemical resistance, and abrasion resistance. Furthermore, because of the opposite side Since the arithmetic mean roughness Ra of the surfaces of the two contact faces 26 and 27 is set to 0.1 or more and 2 or less, it is possible to ensure more excellent sealing performance (sealing property).
再者，由於該環本體1之橫剖面形狀係矩形狀，且該第一凸部21與第二凸部22係由分離線L21使該環本體1之矩形狀的横剖面分割為二的橫剖面形狀；且由於在該第一凸部21與第二凸部22相互重疊的缺口關閉狀態下，該第一凸部21與第二凸部22之二對應面23、24相互間係具有間隙；因此，在第17圖及第18圖所說明之箭頭M10、M20方向的漏洩將會顯著的減少。即，可改善在第一凸部21與第二凸部22之接合部位的密封性。而且，利用樹脂之射出成形，可容易且價廉的獲得如此形狀之密封環。 Furthermore, since the cross-sectional shape of the ring body 1 is rectangular, and the first convex portion 21 and the second convex portion 22 are separated by a separation line L 21, the rectangular cross section of the ring body 1 is divided into two. a cross-sectional shape; and in a closed state in which the first convex portion 21 and the second convex portion 22 overlap each other, the two corresponding surfaces 23 and 24 of the first convex portion 21 and the second convex portion 22 are mutually connected The gap; therefore, the leakage in the directions of the arrows M 10 and M 20 described in Figs. 17 and 18 will be remarkably reduced. That is, the sealing property at the joint portion between the first convex portion 21 and the second convex portion 22 can be improved. Further, by the injection molding of the resin, the seal ring of such a shape can be obtained easily and inexpensively.
