本発明の第１態様は、
密閉容器内を高圧空間と低圧空間に区画する仕切板と、前記仕切板に隣接する固定スクロールと、前記固定スクロールと噛み合わされて圧縮室を形成する旋回スクロールと、前記旋回スクロールの自転を防止する自転抑制部材と、前記旋回スクロールを支持する主軸受とを有し、前記固定スクロール、前記旋回スクロール、前記自転抑制部材、及び前記主軸受を、前記低圧空間に配置し、前記固定スクロール及び前記旋回スクロールを、前記仕切板と前記主軸受との間に配置したスクロール圧縮機であって、前記主軸受に形成した軸受側嵌合部と、前記固定スクロールに形成したスクロール側嵌合部と、下端部が前記軸受側嵌合部に挿入され、上端部が前記スクロール側嵌合部に挿入される柱状部材とを備え、前記柱状部材の下端部と前記軸受側嵌合部とは固定されており、前記柱状部材の上端部と前記スクロール側嵌合部とが軸方向に摺動自在に嵌合されているとともに、前記柱状部材と前記スクロール側嵌合部との嵌合領域と、前記固定スクロールの渦巻ラップの高さ中心を通る水平面とが、交差する位置関係にあるものである。
The first aspect of the present invention is
A partition plate for dividing the inside of the closed container into a high pressure space and a low pressure space, a fixed scroll adjacent to the partition plate, a orbiting scroll engaged with the stationary scroll to form a compression chamber, and rotation of the orbiting scroll is prevented. The fixed scroll, the orbiting scroll, the rotation inhibiting member, and the main bearing are disposed in the low pressure space, and the stationary scroll and the orbiting are provided. A scroll compressor having a scroll disposed between the partition plate and the main bearing, wherein a bearing side fitting portion formed on the main bearing, a scroll side fitting portion formed on the fixed scroll, and a lower end parts is inserted into the bearing-side fitting portion, and a columnar member which upper end is inserted into the scroll-side fitting portion, the lower end portion of the columnar member shaft The side fitting portion is fixed, together with the upper end of the columnar member and the scroll-side fitting portion is slidably fitted in the axial direction, the columnar member and the scroll-side fitting portion And a horizontal plane passing through the center of height of the spiral wrap of the fixed scroll are in an intersecting positional relationship.
第１態様によれば、固定スクロールの半径方向および接線方向のガス合力の力点位置である渦巻ラップ高さの中心位置と、そのガス合力を支持する固定スクロールの嵌合部と柱状部材とで形成される嵌合領域との軸方向の距離を短くできるので、固定スクロールが転覆する方向の回転モーメントを最小にでき、固定スクロールの転覆を防止することができる。
また、固定スクロールにかかる半径および接線方向のガス合力を、柱状部材とスクロール側嵌合部とで形成される嵌合領域で確実に支持できるため、固定スクロールの転覆をより確実に防止することが出来る。万一、柱状部材の上端部とスクロール側嵌合部とが固定されており、柱状部材の下端部と軸受側嵌合部とが摺動自在に嵌合されていた場合は、固定スクロールと柱状部材は一つの剛体と見なされ、固定スクロールのガス合力を受け止める支持箇所は、軸受側嵌合部となり、固定スクロールの半径方向および接線方向のガス合力の力点位置である渦巻ラップ高さの中心位置と、そのガス合力を支持する箇所の軸方向の距離が長くなってしまい、転覆しやすくなってしまう。
According to the first aspect, the fixed scroll is formed by the center position of the spiral wrap height which is the force point position of the gas combined force in the radial direction and tangential direction of the fixed scroll, and the fitting portion of the fixed scroll supporting the gas combined force and the columnar member Since the axial distance between the fixed scroll and the fitting area can be shortened, the rotational moment in the direction in which the fixed scroll overturns can be minimized, and the overturn of the fixed scroll can be prevented.
Further, since the radius and tangential gas total force applied to the fixed scroll can be reliably supported by the fitting region formed by the columnar member and the scroll side fitting portion, it is possible to more reliably prevent the overturning of the fixed scroll. It can. If the upper end portion of the columnar member and the scroll side fitting portion are fixed and the lower end portion of the columnar member and the bearing side fitting portion are slidably fitted, the fixed scroll and the columnar portion are fixed. The member is regarded as one rigid body, and the support location for receiving the gas total force of the fixed scroll is the bearing side fitting portion, and the center position of the spiral wrap height which is the force point position of the gas combination of radial and tangential directions of the fixed scroll. The axial distance of the portion supporting the resultant gas force becomes long, and it becomes easy to overturn.
本発明の第２態様は、前記固定スクロールの渦巻ラップの高さをＨ、前記柱状部材の上端部と前記スクロール側嵌合部との嵌合領域の軸方向長さをＬとしたとき、Ｈ／２≧Ｌの関係を満たすものである。
The second aspect of the present invention, when the height of the spiral wrap of the fixed scroll H, the axial length of the fitting area between the upper end of the columnar member and the scroll-side fitting portion has a L, H It satisfies the relationship of / 2 ≧ L.
第２様態によれば、柱状部材が嵌合領域のクリアランス内で傾いて設置されていたり、運転中の変形等で、嵌合領域の下端位置や上端位置に柱状部材との接地（接触）点が存在した場合においても、固定スクロールの半径方向および接線方向のガス合力の力点位置である渦巻ラップ高さの中心位置と、接地（接触）点との距離を比較的短く抑えることができるので、固定スクロールの転覆をより防止することが出来る。
According to the second aspect, the columnar member is installed in an inclined manner within the clearance of the fitting region, or the ground (contact) point with the columnar member at the lower end position or the upper end position of the fitting region due to deformation during operation. Even in the case where there is, the distance between the center position of the spiral wrap height, which is the force point position of the combined gas in the radial direction and tangential direction of the fixed scroll, and the ground (contact) point can be kept relatively short. The overturning of the fixed scroll can be further prevented.
本発明の第３態様は、前記固定スクロールの固定渦巻きラップの内壁を、前記旋回スクロールの旋回渦巻きラップの終端近くまで形成して、前記固定渦巻きラップの前記内壁と前記旋回渦巻きラップの外壁とで形成される一方の前記圧縮室の閉じ込み容積と、前記固定渦巻きラップの外壁と前記旋回渦巻きラップの内壁とで形成される他方の前記圧縮室の閉じ込み容積とを異ならせたものである。
In a third aspect of the present invention, the inner wall of the fixed spiral wrap of said fixed scroll, and formed up to near the end of the orbiting spiral wrap of the orbiting scroll, and said inner wall and outer wall of the orbiting spiral wrap of the fixed spiral wrap while the the closed narrowing the volume of the compression chamber to be formed, in which was different from the confinement volume of said fixed other of the compression chamber formed by the outer wall and the inner wall of the orbiting spiral wrap of the spiral wrap.
第３様態によれば、最大限の吸入ガスの閉じ込み容積を確保することで、渦巻きラップの高さを低くできる。従って、固定スクロールが、仕切板と主軸受との間で軸方向に動くことができ、吐出空間の圧力によって固定スクロールを旋回スクロールに押し付けて、固定スクロールと旋回スクロールとの密閉性を確保するスクロール圧縮機においては、渦巻きラップの高さが低い方が固定スクロールを安定させることができるので、さらに固定スクロールの転覆を防止することできる。
According to the third aspect, the height of the spiral wrap can be lowered by securing the maximum suction gas confinement volume. Therefore, the fixed scroll can move axially between the partition plate and the main bearing, and the pressure of the discharge space presses the fixed scroll against the orbiting scroll to ensure the tightness between the stationary scroll and the orbiting scroll In the compressor, the smaller the height of the spiral wrap is, the more stable the fixed scroll can be, so that the overturn of the fixed scroll can be further prevented.
本発明の第４態様は、前記固定スクロールに形成され、前記圧縮室と前記低圧空間とを連通する吸入部を備え、前記固定スクロールの固定渦巻きラップのラップ端面の外周部で、前記主軸受の軸受中心に対して前記吸入部と半径方向で重ならない領域の最小距離をＲとしたとき、Ｈ≦Ｒの関係を満たすものである。
The fourth aspect of the present invention is formed in the fixed scroll includes a suction portion communicating with said with said compression chamber low-pressure space, in the outer peripheral portion of the wrap end surface of the fixed spiral wrap of said fixed scroll, said main bearing when the minimum distance of the region not overlapping with the suction unit and the radial direction is R with respect to the bearing center, it satisfies the relationship H ≦ R.
第４様態によれば、固定スクロールの渦巻ラップの端面と旋回スクロールとの接地（接触）範囲が大きくなり、固定スクロールの背面にかかる圧力によって、固定スクロールが旋回スクロールに押し付けられる場合に発生する固定スクロールの転覆を防止する方向の回転モーメントを大きくすることができるので、固定スクロールの転覆をさらに防止することができる。 According to the fourth aspect, the contact (contact) range of the end face of the spiral wrap of the fixed scroll and the orbiting scroll is increased, and the pressure generated on the back of the fixed scroll causes the fixed scroll to be fixed when it is pressed against the orbiting scroll Since the rotational moment in the direction to prevent the roll overturn can be increased, the rollover of the fixed scroll can be further prevented.
