Description

本発明は、圧縮機ユニットに関する。 The present invention relates to a compressor unit.

従来から、特許文献１（特開平９−１３７７８８号公報）に示されるような圧縮機ユニットが知られている。この圧縮機ユニットは、主に圧縮機本体と、圧縮機本体と配管を介して連結されるアキュムレータとからなる。アキュムレータの下部に取り付けられた略Ｌ字状の配管からなる排出口は、圧縮機本体に設けられた吸入配管に水平方向に挿入され、溶接等により固定される。アキュムレータの胴部は、圧縮機本体に固定されたブランケットと、アキュムレータの胴部に巻き付けてアキュムレータをブランケットに水平方向に押し付けて固定するバンドと、で圧縮機本体に固定されている。アキュムレータ胴部の圧縮機本体へのバンドによる固定は、アキュムレータ下部の排出口と圧縮機本体の吸入配管との固定後に行われる。 Conventionally, a compressor unit as shown in Patent Document 1 (Japanese Patent Laid-Open No. 9-137788) is known. The compressor unit mainly includes a compressor main body and an accumulator connected to the compressor main body via a pipe. A discharge port composed of a substantially L-shaped pipe attached to the lower part of the accumulator is inserted in a horizontal direction into a suction pipe provided in the compressor body and fixed by welding or the like. The accumulator body is fixed to the compressor body with a blanket fixed to the compressor body and a band wound around the accumulator body and pressing the accumulator against the blanket in the horizontal direction. The accumulator body is fixed to the compressor body by a band after the discharge port at the lower part of the accumulator and the suction pipe of the compressor body are fixed.

圧縮機本体に設けられた吸入配管に対する、アキュムレータの排出口の挿入代は、取り付け精度などの要因によってばらつきが生じやすい。挿入代が変化すると、圧縮機本体に対するアキュムレータの角度が変化するため、挿入代のばらつきは、圧縮機本体に対するアキュムレータの姿勢のばらつきにつながる。 The insertion allowance of the discharge port of the accumulator with respect to the suction pipe provided in the compressor body is likely to vary depending on factors such as mounting accuracy. When the insertion allowance changes, the angle of the accumulator with respect to the compressor main body changes, so that the variation in the insertion allowance leads to the variation in the attitude of the accumulator with respect to the compressor main body.

アキュムレータ胴部の圧縮機本体へのバンドによる固定は、圧縮機本体とアキュムレータとをつなぐ配管の固定後に行われるため、従来の圧縮機ユニットでは、アキュムレータの圧縮機本体に対する姿勢の変化によって、バンドとアキュムレータの胴部の接触面が変化する。その結果、アキュムレータの固有振動特性がばらつくことがある。 Since the accumulator body is fixed to the compressor body with the band after the pipe connecting the compressor body and the accumulator is fixed, in the conventional compressor unit, the band and the accumulator body are changed by the change in the posture of the accumulator with respect to the compressor body. The contact surface of the accumulator trunk changes. As a result, the natural vibration characteristics of the accumulator may vary.

つまり、従来の圧縮ユニットでは、圧縮機本体の吸入配管に対するアキュムレータの排出口の挿入代がばらつくと、アキュムレータの固有振動特性もばらつきやすいという問題がある。 In other words, the conventional compression unit has a problem that the natural vibration characteristics of the accumulator tend to vary if the insertion cost of the discharge port of the accumulator with respect to the suction pipe of the compressor body varies.

本発明の課題は、アキュムレータ等の流体通過容器の固有振動特性のばらつきを低減した圧縮機ユニットを提供することにある。 The subject of this invention is providing the compressor unit which reduced the dispersion | variation in the natural vibration characteristic of fluid passage containers, such as an accumulator.

本発明の第１観点に係る圧縮機ユニットは、圧縮機本体と、流体通過容器と、支持台と、支持部材とからなる。圧縮機本体は、円筒部を有し、圧縮対象である流体の出入口が形成されている。流体通過容器は、流体の通過する配管を介して圧縮機本体の出入口に連結される。支持台は圧縮機本体に固定される。支持部材は、支持台に支持される支持部を有し、流体通過容器を支持台に固定する。支持部材は、支持部を中心として支持台に対して回動し、流体通過容器の側面と支持部材の支持面とが略正対する。 The compressor unit which concerns on the 1st viewpoint of this invention consists of a compressor main body, a fluid passage container, a support stand, and a support member. The compressor main body has a cylindrical portion and is formed with an inlet / outlet for a fluid to be compressed. The fluid passage container is connected to an inlet / outlet of the compressor body through a pipe through which the fluid passes. The support base is fixed to the compressor body. The support member has a support portion supported by the support base, and fixes the fluid passage container to the support base. The support member rotates with respect to the support base about the support portion, and the side surface of the fluid passage container and the support surface of the support member are substantially facing each other.

この圧縮機ユニットでは、支持部材が支持台に対して回動し、流体通過容器の側面と支持部材の支持面が略正対するため、流体通過容器と支持部材の接触面は一定となりやすい。その結果、流体通過容器の固有振動特性のばらつきが低減される。 In this compressor unit, the support member rotates with respect to the support base, and the side surface of the fluid passage container and the support surface of the support member face each other, so that the contact surface between the fluid passage container and the support member tends to be constant. As a result, variations in the natural vibration characteristics of the fluid passage container are reduced.

本発明の第２観点に係る圧縮機ユニットは、第１観点に係る圧縮機ユニットであって、支持部材は、支持部の少なくとも一箇所でボルトにより支持台に軸支されている。ボルトは、支持部材の回動方向に略垂直に取り付けられる。支持部材の回動方向に垂直な方向とは、支持部材の回動時に支持部材を形成する支持部近傍の一点が移動する平面に垂直な方向をいう。 The compressor unit which concerns on the 2nd viewpoint of this invention is a compressor unit which concerns on a 1st viewpoint, Comprising: The support member is pivotally supported by the support stand with the volt | bolt in at least one location of a support part. The bolt is attached substantially perpendicular to the rotation direction of the support member. The direction perpendicular to the rotation direction of the support member refers to a direction perpendicular to a plane in which one point in the vicinity of the support portion that forms the support member moves when the support member rotates.

この圧縮機ユニットでは、支持部材の回動する方向と垂直にボルトが取り付けられるため、支持部材がスムーズに回動し、流体通過容器と支持部材との接触面は一定となりやすい。その結果、流体通過容器の固有振動特性のばらつきが低減されやすい。 In this compressor unit, since the bolt is attached perpendicularly to the direction in which the support member rotates, the support member rotates smoothly, and the contact surface between the fluid passage container and the support member tends to be constant. As a result, variations in the natural vibration characteristics of the fluid passage container are likely to be reduced.

本発明の第３観点に係る圧縮機ユニットは、第１観点に係る圧縮機ユニットであって、支持台は、圧縮機本体の円筒部の外周面に沿って固定される円弧状の固定部を有する。支持部材は、支持部の少なくとも一箇所でボルトにより支持台に軸支される。ボルトは、圧縮機本体の中心軸に垂直な面での断面視において、固定部と円筒部の外周面との円弧境界線の中央点の接線方向に略沿った方向に取り付けられる。 The compressor unit which concerns on the 3rd viewpoint of this invention is a compressor unit which concerns on a 1st viewpoint, Comprising: A support stand has the circular-arc-shaped fixing | fixed part fixed along the outer peripheral surface of the cylindrical part of a compressor main body. Have. The support member is pivotally supported on the support base by a bolt at at least one location of the support portion. The bolt is attached in a direction substantially along the tangential direction of the center point of the arc boundary line between the fixed portion and the outer peripheral surface of the cylindrical portion in a cross-sectional view in a plane perpendicular to the central axis of the compressor body.

この圧縮機ユニットでは、圧縮機本体の円筒部の外周面と支持台の固定部との境界線の中央点の接線方向にボルトが取り付けられるため、流体通過容器が圧縮機本体に対して前傾もしくは後傾する場合に、支持部材は流体通過容器の姿勢の変化に追従しやすく、流体通過容器と支持部材との接触面は一定となりやすい。その結果、流体通過容器の固有振動特性のばらつきが低減されやすい。また、支持台が圧縮機本体の外周面に沿って固定される固定部を有するため、支持台が圧縮機本体に強く固定されやすい。 In this compressor unit, since the bolt is attached in the tangential direction of the center point of the boundary line between the outer peripheral surface of the cylindrical portion of the compressor body and the fixing portion of the support base, the fluid passage container is inclined forward with respect to the compressor body. Alternatively, when tilting backward, the support member easily follows a change in the posture of the fluid passage container, and the contact surface between the fluid passage container and the support member tends to be constant. As a result, variations in the natural vibration characteristics of the fluid passage container are likely to be reduced. Moreover, since the support base has a fixing portion that is fixed along the outer peripheral surface of the compressor main body, the support base is easily fixed strongly to the compressor main body.

本発明の第４観点に係る圧縮機ユニットは、第１観点から第３観点のいずれかに係る圧縮機ユニットであって、支持台は、凹形状もしくは凸形状の第１連結部を有する。支持部材は、第１連結部と対をなす凸形状もしくは凹形状の第２連結部を有する。第１連結部と第２連結部とは連結される。支持部材は、第１連結部と第２連結部との接点を支持部として、接点を中心に回動する。 The compressor unit which concerns on the 4th viewpoint of this invention is a compressor unit which concerns on either of a 1st viewpoint to the 3rd viewpoint, Comprising: A support stand has a 1st connection part of a concave shape or a convex shape. The support member has a convex or concave second coupling part that forms a pair with the first coupling part. The first connecting part and the second connecting part are connected. The support member rotates around the contact point with the contact point between the first connection portion and the second connection portion as a support portion.

この圧縮機ユニットでは、支持台と支持部材とを対となる凸部と凹部とで連結させ、凸部と凹部との接点を中心として支持部材を回動させるため、流体通過容器と支持部材の接触面は一定となりやすい。その結果、流体通過容器の固有振動特性のばらつきが低減されやすい。また、このような構成であれば、流体通過容器の固有振動特性のばらつき低減が、組立容易に実現されやすい。 In this compressor unit, the support base and the support member are connected by a pair of convex portions and concave portions, and the support member is rotated around the contact point between the convex portions and the concave portions. The contact surface tends to be constant. As a result, variations in the natural vibration characteristics of the fluid passage container are likely to be reduced. Also, with such a configuration, it is easy to assemble a reduction in variation in the natural vibration characteristics of the fluid passage container.

Furthermore, the fluid passage container is easily fixed strongly to the compressor body. As a result, variations in the natural vibration characteristics of the fluid passage container are likely to be reduced.

締結バンド６０について、図２および図３に基づいて説明する。 (2-5) Fastening band 60
The fastening band 60 is demonstrated based on FIG. 2 and FIG.

締結バンド６０は、支持台３０と緩衝ゴム部材５０とが接触した状態でアキュムレータ４０を支持台３０に押さえつける金属製の板状部材である。より具体的には、締結バンド６０は、支持台３０の接触部３４，３５のアキュムレータ４０側の面に緩衝ゴム部材５０が接触した状態でアキュムレータ４０を支持台３０に押さえつける。 The fastening band 60 is a metal plate-like member that presses the accumulator 40 against the support base 30 in a state where the support base 30 and the buffer rubber member 50 are in contact with each other. More specifically, the fastening band 60 presses the accumulator 40 against the support base 30 in a state where the buffer rubber member 50 is in contact with the surface of the contact portions 34 and 35 of the support base 30 on the accumulator 40 side.

締結バンド６０は、主として、バンド本体部６１と、支持部としてのバンド取付部６２およびバンド固定部６３とを有している。 The fastening band 60 mainly has a band main body portion 61, a band attaching portion 62 and a band fixing portion 63 as support portions.

バンド本体部６１のアキュムレータ４０側の面には、その一部に緩衝ゴム部材５０が貼り付けられている。バンド本体部６１は、緩衝ゴム部材５０を介してアキュムレータ４０を支持台３０に対して押さえつける。バンド本体部６１は、圧縮機本体２０の中心軸Ｏ−Ｏに垂直な断面で見た場合、図２のように略円弧状である。 A buffer rubber member 50 is attached to a part of the surface of the band main body 61 on the accumulator 40 side. The band main body 61 presses the accumulator 40 against the support base 30 via the shock absorbing rubber member 50. When viewed in a cross section perpendicular to the central axis OO of the compressor main body 20, the band main body 61 has a substantially arc shape as shown in FIG. 2.

後述のように締結バンド６０は、バンド取付部６２に設けられた取付穴６２ａとバンド固定部６３に設けられたボルト穴６３ａを中心として回動可能である。その結果、アキュムレータ４０の支持面であるバンド本体部６１のアキュムレータ４０側の面と、アキュムレータ４０の側面である胴部４２の外周面とは略正対する。言い換えれば、バンド本体部６１のアキュムレータ側の面は、アキュムレータ４０の胴部４２の中心軸Ｐ−Ｐと略平行である。つまり、アキュムレータ４０が圧縮機本体２０に対して傾いても、締結バンド６０がアキュムレータ４０の傾きに追従し、バンド本体部６１と胴部４２の接触面はほぼ一定となる。さらに、バンド本体部６１と胴部４２の緩衝ゴム部材５０を介した接触面における圧力分布を、バンド本体部６１の板圧方向に切断した断面で見た場合に、圧力が断面に沿って一定になりやすいように、バンド本体部６１は緩衝ゴム部材５０を胴部４２に対して押し付けることが可能である。 As will be described later, the fastening band 60 can rotate around a mounting hole 62 a provided in the band attaching portion 62 and a bolt hole 63 a provided in the band fixing portion 63. As a result, the surface on the accumulator 40 side of the band main body portion 61 that is the support surface of the accumulator 40 and the outer peripheral surface of the trunk portion 42 that is the side surface of the accumulator 40 face each other. In other words, the surface on the accumulator side of the band main body portion 61 is substantially parallel to the central axis PP of the trunk portion 42 of the accumulator 40. That is, even if the accumulator 40 is inclined with respect to the compressor main body 20, the fastening band 60 follows the inclination of the accumulator 40, and the contact surface between the band main body portion 61 and the trunk portion 42 is substantially constant. Furthermore, when the pressure distribution on the contact surface of the band main body portion 61 and the body portion 42 through the buffer rubber member 50 is viewed in a cross section cut in the plate pressure direction of the band main body portion 61, the pressure is constant along the cross section. The band main body 61 can press the shock absorbing rubber member 50 against the trunk 42 so that the band main body 61 tends to become.

バンド取付部６２は、バンド本体部６１の両端のうち、バンド本体部６１の固定部３１の第１保持部３６に対向する一端に設けられる。バンド取付部６２は、支持台３０の第１保持部３６に備えられた突出部３８に回動可能に取り付けられる。具体的には、バンド取付部６２には、突出部３８の円盤平面３８ｂよりやや大きな内径の取付穴６２ａが形成されており、取付穴６２ａを四角柱部３８ａに掛けて連結すると、四角柱部３８ａは取付穴６２ａを軸支する。円盤平面３８ｂは、取付穴６２ａが容易に突出部３８から外れることを防止する。 The band attaching portion 62 is provided at one end of the both ends of the band main body portion 61 facing the first holding portion 36 of the fixing portion 31 of the band main body portion 61. The band attaching portion 62 is rotatably attached to the protruding portion 38 provided in the first holding portion 36 of the support base 30. Specifically, the band attachment portion 62 is formed with an attachment hole 62a having an inner diameter slightly larger than the disk plane 38b of the protruding portion 38, and when the attachment hole 62a is hung on and connected to the square pillar portion 38a, the rectangular pillar portion 38a pivotally supports the mounting hole 62a. The disk plane 38b prevents the mounting hole 62a from easily coming off the protruding portion 38.

バンド固定部６３は、バンド取付部６２とは逆側に位置するバンド本体部６１の一端に設けられる。バンド固定部６３には、支持台３０の第２保持部３７のボルト穴３７ａに対向するボルト穴６３ａが形成されている。バンド固定部６３は、ボルト穴３７ａおよび６３ａを貫通するボルト（図示せず）によって支持台３０の第２保持部３７に固定される。ボルトを中心として締結バンド６０は回動可能である。 The band fixing portion 63 is provided at one end of the band main body portion 61 located on the opposite side to the band attaching portion 62. The band fixing portion 63 is formed with a bolt hole 63 a that faces the bolt hole 37 a of the second holding portion 37 of the support base 30. The band fixing part 63 is fixed to the second holding part 37 of the support base 30 by bolts (not shown) penetrating the bolt holes 37a and 63a. The fastening band 60 is rotatable around the bolt.

（３）特徴
（３−１）
本実施形態の圧縮機ユニット１では、圧縮機本体２０と、アキュムレータ４０と、支持台３０と、締結バンド６０とからなる。圧縮機本体２０は、円筒部２１ａを有し、圧縮対象である流体の出入口として吸入管２２が形成されている。アキュムレータ４０は、流体の通過する配管４１を介して圧縮機本体２０の吸入管２２に連結される。支持台３０は圧縮機本体２０に固定される。締結バンド６０は、支持台３０に支持されるバンド取付部６２とバンド固定部６３とを有し、アキュムレータ４０を支持台３０に固定する。締結バンド６０が、バンド取付部６２とバンド固定部６３を中心として支持台３０に対して回動し、アキュムレータ４０の側面と締結バンド６０の支持面とが略正対する。 (3) Features (3-1)
The compressor unit 1 according to the present embodiment includes a compressor main body 20, an accumulator 40, a support base 30, and a fastening band 60. The compressor body 20 has a cylindrical portion 21a, and a suction pipe 22 is formed as an inlet / outlet of a fluid to be compressed. The accumulator 40 is connected to the suction pipe 22 of the compressor body 20 via a pipe 41 through which fluid passes. The support base 30 is fixed to the compressor body 20. The fastening band 60 has a band mounting portion 62 and a band fixing portion 63 that are supported by the support base 30, and fixes the accumulator 40 to the support base 30. The fastening band 60 rotates with respect to the support base 30 around the band attaching portion 62 and the band fixing portion 63, and the side surface of the accumulator 40 and the support surface of the fastening band 60 are substantially facing each other.

ここでは、締結バンド６０が支持台３０に対して回動し、アキュムレータ４０の側面である胴部４２の外周面と、アキュムレータ４０の支持面としてのバンド本体部６１のアキュムレータ４０側の面とが正対する。言い換えれば、胴部４２の中心軸Ｐ−Ｐと、バンド本体部６１のアキュムレータ４０側の面とが平行である。つまり、アキュムレータ４０が圧縮機本体２０に対して傾いても、締結バンド６０がアキュムレータ４０の傾きに追従するため、バンド本体部６１と胴部４２の接触面は一定となりやすい。さらに、バンド本体部６１と胴部４２の緩衝ゴム部材５０を介した接触面における圧力分布を、バンド本体部６１の板圧方向に切断した断面で見た場合に、圧力が断面に沿って一定になりやすいように、バンド本体部６１は緩衝ゴム部材５０を胴部４２に対して押し付け可能である。その結果、アキュムレータ４０の固有振動特性のばらつきが低減されやすい。 Here, the fastening band 60 rotates with respect to the support base 30, and the outer peripheral surface of the trunk portion 42 that is the side surface of the accumulator 40 and the surface on the accumulator 40 side of the band main body portion 61 that serves as the support surface of the accumulator 40. Face up. In other words, the central axis PP of the trunk portion 42 and the surface of the band main body portion 61 on the accumulator 40 side are parallel. That is, even if the accumulator 40 is inclined with respect to the compressor main body 20, the fastening band 60 follows the inclination of the accumulator 40, so that the contact surface between the band main body portion 61 and the trunk portion 42 is likely to be constant. Furthermore, when the pressure distribution on the contact surface of the band main body portion 61 and the body portion 42 through the buffer rubber member 50 is viewed in a cross section cut in the plate pressure direction of the band main body portion 61, the pressure is constant along the cross section. The band main body portion 61 can press the cushion rubber member 50 against the body portion 42 so as to easily become. As a result, variations in the natural vibration characteristics of the accumulator 40 are likely to be reduced.

なお、胴部４２の外周面と、バンド本体部６１のアキュムレータ４０側の面とは正対することが望ましいが、略正対であってもかまわない。すなわち、胴部４２の中心軸Ｐ−Ｐと、バンド本体部６１のアキュムレータ４０側の面とが略平行であってもかまわない。 Although it is desirable that the outer peripheral surface of the trunk portion 42 and the surface of the band main body portion 61 on the accumulator 40 side are facing each other, they may be substantially facing each other. That is, the central axis PP of the trunk portion 42 and the surface of the band main body 61 on the accumulator 40 side may be substantially parallel.

（３−２）
本実施形態の圧縮機ユニット１では、締結バンド６０は、バンド固定部６３でボルトにより支持台３０に軸支されている。ボルトは、締結バンド６０の回動方向に略垂直に取り付けられる。締結バンド６０の回動方向に垂直な方向とは、締結バンド６０の回動時に支持部材を形成する支持部近傍の一点が移動する平面に垂直な方向をいう。 (3-2)
In the compressor unit 1 of the present embodiment, the fastening band 60 is pivotally supported on the support base 30 by bolts at the band fixing portion 63. The bolt is attached substantially perpendicular to the rotation direction of the fastening band 60. The direction perpendicular to the rotation direction of the fastening band 60 refers to a direction perpendicular to the plane in which one point in the vicinity of the support portion forming the support member moves when the fastening band 60 rotates.

ここでは、締結バンド６０の回動する方向と垂直にボルトが取り付けられるため、締結バンド６０がスムーズに回動し、アキュムレータ４０と締結バンド６０の接触面は常に一定となりやすい。その結果、アキュムレータ４０の固有振動特性のばらつきが低減されやすい。 Here, since the bolt is attached perpendicular to the direction in which the fastening band 60 rotates, the fastening band 60 rotates smoothly, and the contact surface between the accumulator 40 and the fastening band 60 tends to be always constant. As a result, variations in the natural vibration characteristics of the accumulator 40 are likely to be reduced.

なお、締結バンド６０の回動する方向と、ボルトの取り付け方向とは垂直であることが望ましいが、略垂直であってもかまわない。 The direction in which the fastening band 60 rotates and the direction in which the bolt is attached are preferably perpendicular, but may be substantially perpendicular.

（３−３）
本実施形態の圧縮機ユニット１では、支持台３０は、圧縮機本体２０の円筒部２１ａの外周面に沿って固定される円弧状の固定部３１を有する。締結バンド６０は、バンド固定部６３でボルトにより支持台３０に軸支される。ボルトは、圧縮機本体２０の中心軸に垂直な面での断面視において、固定部３１と円筒部２１ａの外周面との円弧境界線の中央点の接線方向に略沿った方向に取り付けられる。 (3-3)
In the compressor unit 1 of the present embodiment, the support base 30 has an arcuate fixing portion 31 that is fixed along the outer peripheral surface of the cylindrical portion 21 a of the compressor body 20. The fastening band 60 is pivotally supported on the support base 30 by a bolt at the band fixing portion 63. The bolt is attached in a direction substantially along the tangential direction of the center point of the arc boundary line between the fixed portion 31 and the outer peripheral surface of the cylindrical portion 21 a in a cross-sectional view on a plane perpendicular to the central axis of the compressor body 20.

ここでは、圧縮機本体２０の円筒部２１ａの外周面と支持台３０の固定部３１との境界線の中央点の接線方向にボルトが取り付けられるため、アキュムレータ４０が圧縮機本体２０に対して前傾もしくは後傾しても、締結バンド６０はアキュムレータ４０の姿勢の変化に追従しやすい。そのため、アキュムレータ４０と締結バンド６０の接触面は一定となりやすい。その結果、アキュムレータ４０の固有振動特性のばらつきが低減されやすい。また、支持台３０が圧縮機本体２０の外周面に沿って固定される固定部３１を有するため、支持台３０が圧縮機本体２０に強く固定されやすい。 Here, since the bolt is attached in the tangential direction of the center point of the boundary line between the outer peripheral surface of the cylindrical portion 21 a of the compressor body 20 and the fixing portion 31 of the support base 30, the accumulator 40 is in front of the compressor body 20. Even if it is tilted or tilted backward, the fastening band 60 can easily follow the change in the posture of the accumulator 40. Therefore, the contact surface between the accumulator 40 and the fastening band 60 tends to be constant. As a result, variations in the natural vibration characteristics of the accumulator 40 are likely to be reduced. In addition, since the support base 30 includes the fixing portion 31 that is fixed along the outer peripheral surface of the compressor main body 20, the support base 30 is easily strongly fixed to the compressor main body 20.

なお、ボルトの取り付け方向は、円筒部２１ａの外周面と固定部３１との境界線の中央点の接線方向と同一の場合に限定されず、略同一であってもかまわない。 The bolt mounting direction is not limited to the same tangential direction of the center point of the boundary line between the outer peripheral surface of the cylindrical portion 21 a and the fixed portion 31, and may be substantially the same.

（３−４）
本実施形態の圧縮機ユニット１では、圧縮機本体２０の吸入管２２と、圧縮機本体２０とアキュムレータ４０を連結する配管４１がロウ付けにより固定されている。 (3-4)
In the compressor unit 1 of the present embodiment, the suction pipe 22 of the compressor body 20 and the pipe 41 that connects the compressor body 20 and the accumulator 40 are fixed by brazing.

吸入管２２と、アキュムレータ４０につながる配管４１をロウ付けで固定した結果、アキュムレータ４０の姿勢にばらつきが生じても、締結バンド６０が支持台３０に対して回動し、アキュムレータ４０の側面である胴部４２と締結バンド６０の支持面６１が正対しやすい。そのため、アキュムレータ４０と締結バンド６０の接触面は一定となりやすく、アキュムレータ４０の固有振動特性のばらつきが低減されやすい。 As a result of fixing the suction pipe 22 and the pipe 41 connected to the accumulator 40 by brazing, even if the posture of the accumulator 40 varies, the fastening band 60 rotates with respect to the support base 30 and is the side surface of the accumulator 40. The body 42 and the support surface 61 of the fastening band 60 are easy to face each other. Therefore, the contact surface between the accumulator 40 and the fastening band 60 tends to be constant, and variations in the natural vibration characteristics of the accumulator 40 are likely to be reduced.

（４）変形例
（Ａ）
本変形例の圧縮機ユニットでは、上記の第１保持部３６およびバンド取付部６２の組合せに変えて、図４のような連結部１３６および係止爪部１６２の組み合わせで締結バンド１６０を支持台１３０に対して回動可能に支持している。以下に、本実施形態の圧縮機ユニットと変形例の相違点のみ示す。 (4) Modification (A)
In the compressor unit of this modification, instead of the combination of the first holding part 36 and the band attaching part 62, the fastening band 160 is supported by a combination of the connecting part 136 and the locking claw part 162 as shown in FIG. 130 is supported to be rotatable. Only the differences between the compressor unit of the present embodiment and the modifications will be described below.

まず、連結部１３６について説明する。なお、支持台１３０の構造は、連結部１３６を除き、支持台３０の構造と同様であるため省略する。 First, the connecting part 136 will be described. Note that the structure of the support base 130 is the same as the structure of the support base 30 except for the connecting portion 136, and is therefore omitted.

連結部１３６は、圧縮機本体２０の中心軸Ｏ−Ｏに垂直な断面視において、接触部１３４の端部から圧縮機本体２０側に折り返される板状部分である。連結部１３６には、後述する締結バンド６０を挿入可能な略長方形状の角穴１３６ａが形成されている。連結部１３６の端面には、図４ａのように、圧縮機本体２０に向かって半円盤状の突起部１３８を有する。 The connecting portion 136 is a plate-like portion that is folded back from the end of the contact portion 134 toward the compressor body 20 in a cross-sectional view perpendicular to the central axis OO of the compressor body 20. The connecting portion 136 is formed with a substantially rectangular square hole 136a into which a fastening band 60 described later can be inserted. As shown in FIG. 4 a, a semi-disc-shaped protrusion 138 is provided on the end surface of the connecting portion 136 toward the compressor body 20.

次に、支持部である第２連結部としての係止爪部１６２について説明する。なお、締結バンド１６０の構造は、係止爪部１６２を除き、締結バンド１６０の構造と同様であるため省略する。 Next, the latching claw portion 162 as the second connecting portion that is the support portion will be described. Note that the structure of the fastening band 160 is the same as the structure of the fastening band 160 except for the locking claw 162, and is omitted.

係止爪部１６２は、圧縮機本体２０の中心軸Ｏ−Ｏに垂直な断面視において、バンド本体部１６１の両端のうち、支持台１３０の連結部１３６に対向する側の端部から圧縮機本体２０側に向けて延びた後にアキュムレータ４０側に折り返される板状部分である。係止爪部１６２は、角穴１３６ａに挿入され、第１連結部としての突起部１３８に係止されている。突起部１３８が半円盤状であるため、係止爪部１６２と突起部１３８は点で接することとなり、締結バンド１６０は突起部１３８を支持部として図４ｂに示した矢印Ｒ方向に回動可能である。 The locking claw 162 is a compressor from the end of the band main body 161 on the side facing the connecting portion 136 of both ends of the band main body 161 in a cross-sectional view perpendicular to the central axis OO of the compressor main body 20. It is a plate-like portion that extends toward the main body 20 and is then folded back to the accumulator 40 side. The locking claw 162 is inserted into the square hole 136a and locked to the protrusion 138 as the first connecting portion. Since the protruding portion 138 has a semi-disc shape, the locking claw portion 162 and the protruding portion 138 come into contact with each other at a point, and the fastening band 160 can rotate in the direction of arrow R shown in FIG. 4B with the protruding portion 138 as a support portion. It is.

さらに、本変形例の圧縮機ユニット２０１では、上記の第１保持部３６およびバンド取付部６２の組合せに変えて、図５のような連結部２３６および係止爪部２６２の組み合わせで締結バンド２６０を支持台２３０に対して回動可能に支持している。以下に、本実施形態の圧縮機ユニットと変形例の相違点のみ示す。 Further, in the compressor unit 201 of this modification, instead of the combination of the first holding part 36 and the band attaching part 62 described above, a fastening band 260 is obtained by a combination of the connecting part 236 and the locking claw part 262 as shown in FIG. Is supported to be rotatable with respect to the support base 230. Only the differences between the compressor unit of the present embodiment and the modifications will be described below.

まず、連結部２３６について説明する。なお、支持台２３０の構造は、連結部２３６を除き、支持台３０の構造と同様であるため省略する。 First, the connecting part 236 will be described. Note that the structure of the support base 230 is the same as the structure of the support base 30 except for the connecting portion 236, and thus the description thereof is omitted.

連結部２３６は、圧縮機本体２０の中心軸Ｏ−Ｏに垂直な断面視において、接触部２３４の端部から圧縮機本体２０側に折り返される板状部分である。連結部２３６の端面には、図５ａのように圧縮機本体２０に向かって突出する半楕円板形状の突起部２３８を有する。 The connecting portion 236 is a plate-like portion that is folded back from the end of the contact portion 234 toward the compressor body 20 in a cross-sectional view perpendicular to the central axis OO of the compressor body 20. On the end surface of the connecting portion 236, there is a semi-elliptical plate-shaped protrusion 238 protruding toward the compressor body 20 as shown in FIG. 5a.

次に、支持部である第２連結部としての係止爪部２６２について説明する。なお、締結バンド２６０の構造は、係止爪部２６２を除き、締結バンド２６０の構造と同様であるため省略する。 Next, the latching claw portion 262 as the second connecting portion which is a support portion will be described. Note that the structure of the fastening band 260 is the same as the structure of the fastening band 260 except for the locking claw portion 262, and is omitted.

係止爪部２６２は、圧縮機本体２０の中心軸Ｏ−Ｏに垂直な断面視において、バンド本体部２６１の両端のうち支持台２３０の連結部２３６に対向する側の端部から圧縮機本体２０側に延びた後にアキュムレータ４０側に内向きに折り返される板状部分である。係止爪部２６２は、第１連結部としての突起部２３８に係止されている。突起部２３８は半楕円板形状であるため、係止爪部２６２と突起部２３８は点で接することとなり、締結バンド２６０は突起部２３８を支持部として図５ｂに示した矢印Ｒ方向に回動可能である。 The locking claw 262 is formed from the end of the band main body 261 opposite to the connecting portion 236 of the support base 230 from both ends of the band main body 261 in a cross-sectional view perpendicular to the central axis OO of the compressor main body 20. It is a plate-like portion that extends inward to the accumulator 40 side after extending to the 20 side. The locking claw portion 262 is locked to a protruding portion 238 as a first connecting portion. Since the protruding portion 238 has a semi-elliptical plate shape, the locking claw portion 262 and the protruding portion 238 are in contact with each other at a point, and the fastening band 260 rotates in the direction of arrow R shown in FIG. 5B with the protruding portion 238 as a support portion. Is possible.

本変形例では、支持台１３０，２３０は、第１連結部として凸形状の突起部１３８，２３８を有する。締結バンド１６０，２６０は、突起部１３８，２３８と対をなす凹形状の係止爪部１６２，２６２を第２連結部として有する。突起部１３８，２３８と係止爪部１６２，２６２とは連結される。締結バンド１６０，２６０は、突起部１３８，２３８と係止爪部１６２，２６２との接点を支持部として、接点を中心に回動する。 In the present modification, the support bases 130 and 230 have convex protrusions 138 and 238 as the first connecting portions. The fastening bands 160 and 260 have concave locking claw portions 162 and 262 that form a pair with the protruding portions 138 and 238 as the second connecting portion. The protrusions 138 and 238 and the locking claws 162 and 262 are connected. The fastening bands 160 and 260 rotate around the contact point with the contact point between the projections 138 and 238 and the locking claw portions 162 and 262 as a support portion.

ここでは、支持台１３０，２３０と締結バンド１６０，２６０とを対となる凸形状の突起部１３８，２３８と凹形状の係止爪部１６２，２６２とで連結させ、その接点を中心として締結バンド１６０，２６０を回動させるため、アキュムレータ４０と締結バンド１６０，２６０の接触面は一定となりやすい。その結果、アキュムレータ４０の固有振動特性のばらつきが低減されやすい。また、このような構成であれば、アキュムレータ４０の固有振動特性のばらつき低減が、組立容易に実現されやすい。 Here, the support bases 130 and 230 and the fastening bands 160 and 260 are connected to each other by a pair of convex protrusions 138 and 238 and concave locking claws 162 and 262, and the fastening band is centered on the contact point. Since 160 and 260 are rotated, the contact surface between the accumulator 40 and the fastening bands 160 and 260 tends to be constant. As a result, variations in the natural vibration characteristics of the accumulator 40 are likely to be reduced. Further, with such a configuration, it is easy to assemble easily to reduce variations in the natural vibration characteristics of the accumulator 40.

なお、本変形例では、支持台１３０，２３０側に凸形状の突起部１３８，２３８を設け、締結バンド１６０，２６０側に凹形状の係止爪部１６２，２６２を設けたが、支持台１３０，２３０に係止爪部を設け、締結バンド１６０，２６０に突起部を設けてもよい。この場合にも、本変形例と同様の効果が得られる。 In this modification, convex protrusions 138 and 238 are provided on the support bases 130 and 230 side, and concave locking claw parts 162 and 262 are provided on the fastening bands 160 and 260 side. , 230 may be provided with locking claws, and the fastening bands 160, 260 may be provided with protrusions. Also in this case, the same effect as in the present modification can be obtained.

（Ｂ）
本変形例の圧縮機ユニット３０１では、上記の支持台３０と締結バンド６０の組合せに変えて、図６の支持台３３０および支持部材３８０の組み合わせで、支持部材３８０が支持台３３０に対して回動可能に支持される。 (B)
In the compressor unit 301 of this modification, instead of the combination of the support base 30 and the fastening band 60 described above, the support member 380 rotates relative to the support base 330 by a combination of the support base 330 and the support member 380 of FIG. It is supported movably.

以下に、本実施形態の圧縮機ユニットと変形例の相違点である、支持台３３０と支持部材３８０の構成についてのみ説明する。 Below, only the structure of the support stand 330 and the support member 380 which are the differences of the compressor unit of this embodiment and a modification is demonstrated.

（１）支持台３３０

（２）支持部材３８０
以下、支持部材３８０について、図６に基づいて説明する。 (2) Support member 380
Hereinafter, the support member 380 will be described with reference to FIG.

支持部材３８０は大きく分けて回動部材３７０と固定部材としての締結バンド３６０を有している。 The support member 380 is roughly divided into a rotation member 370 and a fastening band 360 as a fixing member.

The first member mounting portion 373 is provided with a bolt hole 373a opposite to the bolt hole 332a provided in the extending portion 332 of the support base 330. The extending portion 332 and the first member mounting portion 373 are formed by bolts. Connected. The first member contact portion 374 is a plate-like portion that extends from the end portion of the first member attachment portion 373 and extends along the outer peripheral surface of the cylindrical portion of the accumulator 40 in FIG. In FIG. 6, the first member folding portion 375 is a plate-like portion that is folded from the end of the first member contact portion 374 toward the compressor body 20. The first member folded portion 375 is formed with a substantially rectangular square hole 375a.

第２部材３７２も、主に第２部材取付部３７６、第２部材接触部３７７および第２部材折返部３７８とからなる。支持部としての第２部材取付部３７６は、支持台３３０の延出部３３３と略平行にアキュムレータ４０に向かって延出する。第２部材取付部３７６には、支持台３３０の延出部３３３に設けられたボルト穴３３３ａと対向するボルト穴３７６ａが設けられており、延出部３３３と第２部材取付部３７６とはボルトによって連結される。第２部材接触部３７７は、図６において、第２部材取付部３７６の端部から延出し、アキュムレータ４０の円筒部分の外周面に沿う板状部分である。第２部材折返部３７８は、図６において、第２部材接触部３７７の端部から圧縮機本体２０側に折り返される板状部分である。第２部材折返部３７８には、ボルト穴３７８ａが形成されている。 The second member 372 also mainly includes a second member attachment portion 376, a second member contact portion 377, and a second member return portion 378. The second member attachment portion 376 as a support portion extends toward the accumulator 40 substantially in parallel with the extension portion 333 of the support base 330. The second member mounting portion 376 is provided with a bolt hole 376a facing the bolt hole 333a provided in the extending portion 333 of the support base 330.

It is determined. In other words, it is determined that the central axis PP of the trunk portion 42 and the surfaces of the first member contact portion 374 and the second member contact portion 377 on the accumulator 40 side are substantially parallel. As a result, since the rotating member 370 follows the inclination of the accumulator 40, the contact surfaces of the accumulator 40 with the first member contact portion 374 and the second member contact portion 377 tend to be constant.

締結バンド３６０は、回動部材３７０と緩衝ゴム部材５０とが接触した状態でアキュムレータ４０を回動部材３７０に押さえつける金属製の板状部材である。より具体的には、締結バンド３６０は、回動部材３７０の第１部材接触部３７４および第２部材接触部３７７のアキュムレータ４０側の面が緩衝ゴム部材５０に接触した状態で、アキュムレータ４０を回動部材３７０に押さえつける。その結果、アキュムレータ４０は、回動部材３７０の固定されている支持台３３０を介して、圧縮機本体２０に固定される。 The fastening band 360 is a metal plate-like member that presses the accumulator 40 against the rotating member 370 in a state where the rotating member 370 and the shock absorbing rubber member 50 are in contact with each other. More specifically, the fastening band 360 rotates the accumulator 40 in a state where the surfaces of the first member contact portion 374 and the second member contact portion 377 of the rotating member 370 on the accumulator 40 side are in contact with the shock absorbing rubber member 50. Press against the moving member 370. As a result, the accumulator 40 is fixed to the compressor body 20 via the support base 330 to which the rotating member 370 is fixed.

締結バンド３６０は、主として、バンド本体部３６１と、係止爪部３６２と、バンド固定部３６３とを有している。締結バンドの詳細について以下に説明する。ただし、バンド本体部３６１については、上記の実施形態のバンド本体部６１と同様であるので説明は省略する。 The fastening band 360 mainly has a band main body portion 361, a locking claw portion 362, and a band fixing portion 363. Details of the fastening band will be described below. However, since the band main body 361 is the same as the band main body 61 of the above-described embodiment, the description thereof is omitted.

係止爪部３６２は、図６において、バンド本体部３６１の両端のうち、第１部材折返部３７５に対向する側の端部から圧縮機本体２０側に延びた後にアキュムレータ４０側に折り返される板状部分である。係止爪部３６２は、角穴３７５ａによって第１部材折返部３７５に係止されている。 In FIG. 6, the locking claw 362 is a plate that is folded back to the accumulator 40 side after extending from the end of the band body 361 facing the first member folding part 375 to the compressor body 20 side. It is a shaped part. The locking claw portion 362 is locked to the first member folded portion 375 by a square hole 375a.

バンド固定部３６３は、図６において、バンド本体部３６１の両端のうち第２部材折返部３７８に対向する側の端部から第２部材折返部３７８に沿って延びる板状部分である。バンド固定部３６３には、第２部材折返部３７８のボルト穴３７８ａに対向するボルト穴３６３ａが形成されている。バンド固定部３６３は、ボルト穴３７８ａおよび３６３ａを貫通するボルト（図示せず）によって第２部材折返部３７８に固定されている。 In FIG. 6, the band fixing portion 363 is a plate-like portion that extends along the second member folding portion 378 from the end portion of the both ends of the band main body portion 361 facing the second member folding portion 378. The band fixing portion 363 is formed with a bolt hole 363a that faces the bolt hole 378a of the second member folding portion 378. The band fixing portion 363 is fixed to the second member return portion 378 by bolts (not shown) penetrating the bolt holes 378a and 363a.

（３）効果
本変形例では、支持部材３８０は、支持部である第１部材取付部３７３および第２部材取付部３７６を中心に回動する回動部材３７０と、回動部材３７０に連結されアキュムレータ４０を支持台３３０に固定する固定部材としての締結バンド３６０とを有する。 (3) Effects In this modification, the support member 380 is connected to the rotation member 370 that rotates around the first member attachment portion 373 and the second member attachment portion 376 that are support portions, and the rotation member 370. And a fastening band 360 as a fixing member for fixing the accumulator 40 to the support base 330.

Easy to face up. As a result, the contact surface between the accumulator 40 and the support member 380 tends to be always constant. Further, in the present modification, the outer peripheral surface of the trunk portion 42 that is the side surface of the accumulator 40 and the support surface that is the contact surface between the first member contact portion 374 and the second member contact portion 377 and the accumulator 40 are easily aligned. Furthermore, the accumulator 40 is easily fixed strongly by separating the rotating member 380 and the fastening band 360 that is a fixing member. As a result, the variation in the natural vibration characteristics of the accumulator 40 can be further reduced.
