Some portions 13a, 13b, 13c, 13d, 13e of a seat face 13 against which one end face of the electromagnetic coil abuts, are formed to extend to an outer side in a radial direction beyond a center 93g of the electromagnetic coil.

Description

本発明は気体圧縮機(コンプレッサ)に関し、詳細には、回転軸に動力を伝達する電磁クラッチの設置構造の改良に関する。   The present invention relates to a gas compressor (compressor), and more particularly, to an improved installation structure of an electromagnetic clutch that transmits power to a rotating shaft.

従来、空気調和システム(以下、空調システムという。)には、冷媒ガスなどの気体を高圧の圧縮気体に圧縮する圧縮室を有する気体圧縮機が用いられている。   Conventionally, a gas compressor having a compression chamber for compressing a gas such as a refrigerant gas into a high-pressure compressed gas is used in an air conditioning system (hereinafter referred to as an air conditioning system).

この気体圧縮機のうち外部から動力を受けて動作するものは、その動力の入力の受け入れと入力の停止とを切り替えるために、電磁クラッチを備えている。
この電磁クラッチは、プーリと一体的に回転するロータと、円環状に形成された電磁コイルと、電磁コイルの通電によって発生した磁束によりロータの外面に接し、電磁コイルの通電停止によって磁束が消失することによりロータの外面から離れるアーマチュアとを備えている。
電磁コイルは、銅線が巻かれたコイル本体であるコアと、コアを収容したハウジングであるコアケースとを備えており、コアケースの一部が、気体圧縮機のハウジングのノーズの部分に形成された座面に突き当てられた状態で、リテーナによってハウジングに固定されている(特許文献1)。
Among these gas compressors, those that operate by receiving power from the outside are provided with an electromagnetic clutch in order to switch between accepting input of the power and stopping the input.
This electromagnetic clutch contacts the outer surface of the rotor by a rotor that rotates integrally with a pulley, an electromagnetic coil formed in an annular shape, and a magnetic flux generated by energization of the electromagnetic coil, and the magnetic flux disappears when the energization of the electromagnetic coil is stopped. And an armature away from the outer surface of the rotor.
The electromagnetic coil includes a core that is a coil body wound with a copper wire and a core case that is a housing that houses the core, and a part of the core case is formed in a nose portion of the housing of the gas compressor. It is fixed to the housing by a retainer in a state of being abutted against the seat surface (Patent Document 1).

特開2002−106603号公報JP 2002-106603 A

特許文献1に開示された気体圧縮機は、ハウジングのノーズに形成された座面が、円環状に形成された電磁コイルの中心半径(外周径(直径)と内周径(直径)との略中間の位置(電磁コイルの部分ごとの重心の位置)の直径の半分)よりも半径方向の内側にのみ形成されている。
ここで、電磁コイルは、通電によって発生した磁束によりアーマチュアを吸引するが、その反力によって、電磁コイル自体もアーマチュアの側に引かれる荷重を受ける。
一方、通電が停止すると、電磁コイル自体が受けていた荷重がなくなり、電磁コイルは座面に押し付けられた状態に戻る。
In the gas compressor disclosed in Patent Document 1, the seat surface formed on the nose of the housing is an abbreviation of the center radius (outer diameter (diameter) and inner diameter (diameter) of an electromagnetic coil formed in an annular shape. It is formed only on the inner side in the radial direction from the intermediate position (half the diameter of the center of gravity of each part of the electromagnetic coil).
Here, the electromagnetic coil attracts the armature by the magnetic flux generated by energization, but the electromagnetic coil itself receives a load pulled toward the armature by the reaction force.
On the other hand, when the energization is stopped, the load received by the electromagnetic coil itself disappears, and the electromagnetic coil returns to the state of being pressed against the seat surface.

しかし、電磁コイルの端面が突き当てられる座面が、電磁コイルの部分ごとの重心よりも内側にのみ形成されているため、電磁コイルの部分ごとの重心を座面で受けることができない。
このような状況が長期間に亘って繰り返されると、電磁コイルと座面との間に隙間が生じて、電磁コイルとハウジングとの間でガタつきが生じ、このガタつきに起因して異音が発生したり、振動が発生したりする。
However, since the seating surface against which the end face of the electromagnetic coil is abutted is formed only inside the center of gravity of each part of the electromagnetic coil, the center of gravity for each part of the electromagnetic coil cannot be received by the seating surface.
When such a situation is repeated over a long period of time, a gap is generated between the electromagnetic coil and the seating surface, and rattling occurs between the electromagnetic coil and the housing. May occur or vibration may occur.

本発明は上記事情に鑑みなされたものであって、電磁コイルとハウジングとの間のガタつきの発生を防止乃至抑制することができる気体圧縮機を提供することを目的とする。   This invention is made | formed in view of the said situation, Comprising: It aims at providing the gas compressor which can prevent thru | or suppress generation | occurrence | production of the backlash between an electromagnetic coil and a housing.

本発明に係る気体圧縮機は、ハウジングに形成された座面の少なくとも一部を、電磁コイルの中心半径よりも半径方向の外側まで延びたものとすることで、電磁コイルとハウジングとの間のガタつきの発生を防止乃至抑制するものである。
すなわち、本発明に係る気体圧縮機は、回転軸を含む圧縮機本体を収容するハウジングと、前記回転軸を中心とする円環状に形成された電磁コイルを有する電磁クラッチとを備え、前記ハウジングに形成された、前記電磁コイルの一方の端面が突き当てられる座面の少なくとも一部は、前記電磁コイルの中心半径よりも半径方向の外側まで延びて形成されているものである。
In the gas compressor according to the present invention, at least part of the seat surface formed in the housing extends to the outside in the radial direction from the center radius of the electromagnetic coil, so that the space between the electromagnetic coil and the housing is increased. This prevents or suppresses the occurrence of rattling.
That is, a gas compressor according to the present invention includes a housing that houses a compressor body that includes a rotating shaft, and an electromagnetic clutch that has an electromagnetic coil formed in an annular shape around the rotating shaft. At least a part of the formed seating surface against which one end face of the electromagnetic coil is abutted is formed so as to extend outward in the radial direction from the center radius of the electromagnetic coil.

以下、本発明の気体圧縮機に係る実施形態について、図面を参照して説明する。   Hereinafter, an embodiment according to the gas compressor of the present invention will be described with reference to the drawings.

(構成)
本発明に係る気体圧縮機の一実施形態であるベーンロータリ形式のコンプレッサ100(以下、単にコンプレッサ100という。)は、図1に示すように、供給された冷媒ガスG(気体)を高圧に圧縮する圧縮機本体60をハウジング10の内部に収容し、ハウジング10には、電磁クラッチ90が取り付けられている。
このコンプレッサ100は、冷却媒体の気化熱を利用して冷却を行う空気調和システム(以下、単に空調システムという。)の一部として構成され、この空調システムの他の構成要素である凝縮器、膨張弁、蒸発器等とともに、冷却媒体の循環経路上に設けられている。
(Constitution)
A vane rotary type compressor 100 (hereinafter simply referred to as a compressor 100), which is an embodiment of a gas compressor according to the present invention, compresses a supplied refrigerant gas G (gas) to a high pressure as shown in FIG. A compressor main body 60 is accommodated inside the housing 10, and an electromagnetic clutch 90 is attached to the housing 10.
The compressor 100 is configured as a part of an air conditioning system (hereinafter, simply referred to as an air conditioning system) that performs cooling using the heat of vaporization of a cooling medium, and includes a condenser and an expansion that are other components of the air conditioning system. Along with a valve, an evaporator, etc., it is provided on the circulation path of the cooling medium.

コンプレッサ100は、空調システムの蒸発器から取り入れた気体状の冷却媒体としての冷媒ガスGを圧縮し、この圧縮された冷媒ガスGを空調システムの凝縮器に供給する。
凝縮器は、圧縮された冷媒ガスGを周囲の空気等との間で熱交換することにより冷媒ガスGから放熱させて液化させ、高圧で液状の冷媒として膨張弁に送出する。
高圧で液状の冷媒は、膨張弁で低圧化され、蒸発器に送出される。低圧の液状冷媒は、蒸発器において周囲の空気から吸熱して気化し、この冷媒の気化に伴う熱交換により蒸発器周囲の空気を冷却する。
気化した低圧の冷媒ガスGは、コンプレッサ100に戻って圧縮され、以下、上記工程を繰り返す。
The compressor 100 compresses the refrigerant gas G as a gaseous cooling medium taken from the evaporator of the air conditioning system, and supplies the compressed refrigerant gas G to the condenser of the air conditioning system.
The condenser heat-exchanges the compressed refrigerant gas G with ambient air and the like to dissipate heat from the refrigerant gas G and liquefy it, and sends it to the expansion valve as a high-pressure liquid refrigerant.
The high-pressure liquid refrigerant is reduced in pressure by the expansion valve and sent to the evaporator. The low-pressure liquid refrigerant absorbs heat from ambient air and vaporizes in the evaporator, and cools the air around the evaporator by heat exchange accompanying the vaporization of the refrigerant.
The vaporized low-pressure refrigerant gas G returns to the compressor 100 and is compressed, and the above steps are repeated thereafter.

ハウジング10は、一端が閉じられ他端が開放されたケース11と、このケース11の開放された他端を覆うフロントヘッド12とからなり、ボルト等の締結部材によって、フロントヘッド12がケース11に組み付けられている。
フロントヘッド12がケース11に組み付けられた状態で、ハウジング10の内部に空間が形成され、その空間に圧縮機本体60および油分離器70が収容されている。
The housing 10 includes a case 11 having one end closed and the other end opened, and a front head 12 covering the other open end of the case 11. The front head 12 is attached to the case 11 by a fastening member such as a bolt. It is assembled.
With the front head 12 assembled to the case 11, a space is formed inside the housing 10, and the compressor body 60 and the oil separator 70 are accommodated in the space.

圧縮機本体60は、いわゆるベーンロータリ形式の圧縮機であり、回転軸51の回転に伴って容積が変化する圧縮室内の冷媒ガスGを圧縮する。
回転軸51は、図2に示すように、軸心C回りに回転可能に支持されており、フロントヘッド12のノーズ部14に支持された電磁クラッチ90に連結されている。
The compressor body 60 is a so-called vane rotary type compressor, and compresses the refrigerant gas G in the compression chamber whose volume changes as the rotating shaft 51 rotates.
As shown in FIG. 2, the rotating shaft 51 is supported so as to be rotatable around the axis C and is connected to an electromagnetic clutch 90 supported by the nose portion 14 of the front head 12.

電磁クラッチ90は、プーリ91とロータ92と電磁コイル93とアーマチュア94とを備えた構成である。
プーリ91は、ベルトが巻き掛けられてエンジン等の動力源から動力の入力を受ける。
ロータ92は、プーリ91と一体的に形成されており、ラジアルベアリングを介してフロントヘッド12のノーズ部14に固定されていて、回転軸51の軸心C回りに回転可能となっている。
したがって、プーリ91に動力の入力を受けると、プーリ91とロータ92とは一体的に、軸心C回りに回転する。
The electromagnetic clutch 90 includes a pulley 91, a rotor 92, an electromagnetic coil 93, and an armature 94.
The pulley 91 is wound around a belt and receives power input from a power source such as an engine.
The rotor 92 is formed integrally with the pulley 91, is fixed to the nose portion 14 of the front head 12 via a radial bearing, and can rotate about the axis C of the rotary shaft 51.
Accordingly, when power is input to the pulley 91, the pulley 91 and the rotor 92 rotate about the axis C as a unit.

電磁コイル93は、銅線が巻かれたコイル本体であるコア93aと、コア93aを収容したハウジングであるコアケース93bと、コアケース93bの端面に接合された環状板93cとを備えている。
コア93aはコアケース93bに収容されたままの状態で、プーリ91とロータ92とによって仕切られた環状の空間内に、プーリ91およびロータ92に接触しない状態で収容されている。
The electromagnetic coil 93 includes a core 93a that is a coil body wound with a copper wire, a core case 93b that is a housing that accommodates the core 93a, and an annular plate 93c that is joined to an end surface of the core case 93b.
The core 93a is accommodated in an annular space partitioned by the pulley 91 and the rotor 92 without contacting the pulley 91 and the rotor 92 while being accommodated in the core case 93b.

環状板93cは、その中心孔93dにフロントヘッド12のノーズ部14が通されて、リテーナ95により、ノーズ部14に固定されている。
環状板93cの外径(軸心Cからの半径)S1は、軸心Cから二点鎖線で示したコア93aの中心93gまでの距離である中心半径S2よりも長く形成されている。
環状板93cがノーズ部14に固定されている状態で、環状板93cの一方の端面93e(電磁コイルの一方の端面)は、フロントヘッド12に形成された平面の座面13(図3のハッチングで示した部分)に突き当てられて接している。
The nose portion 14 of the front head 12 is passed through the center hole 93 d of the annular plate 93 c and is fixed to the nose portion 14 by a retainer 95.
The outer diameter (radius from the axis C) S1 of the annular plate 93c is formed longer than the center radius S2 that is the distance from the axis C to the center 93g of the core 93a indicated by a two-dot chain line.
In a state where the annular plate 93c is fixed to the nose portion 14, one end surface 93e (one end surface of the electromagnetic coil) of the annular plate 93c is a flat seat surface 13 (hatching in FIG. 3) formed on the front head 12. It is abutted against and touching the part indicated by.

この座面13は、図3に示すように、そのうち少なくとも一部が、電磁コイル93の、二点鎖線で示したコア93aの中心93gよりも軸心Cからの半径方向の外側まで延びて形成されている。
具体的には、図3において、座面13の5つの部分13a,13b,13c,13d,13eが、コア93aの中心93gよりも軸心Cからの半径方向の外側まで延びて形成されている。
As shown in FIG. 3, at least a part of the seating surface 13 is formed to extend from the center 93 g of the core 93 a indicated by a two-dot chain line to the outside in the radial direction from the axis C. Has been.
Specifically, in FIG. 3, five portions 13a, 13b, 13c, 13d, and 13e of the seating surface 13 are formed to extend from the center 93g of the core 93a to the outside in the radial direction from the axis C. .

アーマチュア94は、内リング94aと外リング94bと板バネ94cとを備えている。
内リング94aは、フロントヘッド12から突出した回転軸51の端部に締結されている。
外リング94bは、内リング94aよりも半径方向の外側に張り出して形成されており摩擦係数の高い材料で形成されている。
外リング94bは、ロータ92の、軸心Cに直交する側壁面とわずかな隙間を介して配置されているが、板バネ94cの弾性変形によってロータ92の側壁面に接触する。
板バネ94cは、内リング94aと外リング94bとを連結していて、板バネ94cの、軸心Cの延びた方向に沿っての弾性変形の範囲内で、内リング94aに対して外リング94bが変位するのを許容している。
以上の構成により、アーマチュア94は全体として、回転軸51と一体的に軸心C回りに回転可能となっている。
The armature 94 includes an inner ring 94a, an outer ring 94b, and a leaf spring 94c.
The inner ring 94a is fastened to the end of the rotating shaft 51 protruding from the front head 12.
The outer ring 94b is formed to project outward in the radial direction from the inner ring 94a, and is formed of a material having a high friction coefficient.
The outer ring 94b is disposed through a slight gap from the side wall surface of the rotor 92 that is orthogonal to the axis C, but comes into contact with the side wall surface of the rotor 92 by elastic deformation of the leaf spring 94c.
The leaf spring 94c connects the inner ring 94a and the outer ring 94b, and within the range of elastic deformation of the leaf spring 94c along the direction in which the axis C extends, the outer ring 94a is connected to the inner ring 94a. 94b is allowed to displace.
With the above configuration, the armature 94 as a whole can rotate about the axis C integrally with the rotating shaft 51.

電磁コイル93に通電されると、発生した磁束により、外リング94bがロータ92の側に吸引されてロータ92の側壁面に接し、外リング94bとロータ92の側壁面との接触による摩擦力により、ロータ92の回転がアーマチュア94に伝達され、回転軸51を回転させる。
一方、電磁コイル93への通電が停止されると、アーマチュア94を吸引していた磁束が消失し、外リング94bが板バネ94cの弾性復元力によりロータ92の側壁面から離れ、ロータ92の回転がアーマチュア94に伝達されず、回転軸51は回転しない。
When the electromagnetic coil 93 is energized, the outer ring 94b is attracted to the rotor 92 side by the generated magnetic flux and comes into contact with the side wall surface of the rotor 92, and due to the frictional force caused by the contact between the outer ring 94b and the side wall surface of the rotor 92. The rotation of the rotor 92 is transmitted to the armature 94, and the rotating shaft 51 is rotated.
On the other hand, when the energization to the electromagnetic coil 93 is stopped, the magnetic flux attracting the armature 94 disappears, the outer ring 94b is separated from the side wall surface of the rotor 92 by the elastic restoring force of the leaf spring 94c, and the rotation of the rotor 92 Is not transmitted to the armature 94, and the rotating shaft 51 does not rotate.

(作用)
以上のように構成された本実施形態のコンプレッサ100によると、動力源から入力されている動力によってプーリ91およびロータ92は常時回転している。
ここで、電磁クラッチ90の電磁コイル93に通電されていないときは、アーマチュア94はロータ92に接しないため回転せず、したがって、コンプレッサ100は冷媒ガスGを圧縮する動作を行わない。
一方、電磁クラッチ90の電磁コイル93に通電されているときは、電磁コイル93の発生する磁束によって、アーマチュア94の外リング94bが電磁コイル93に吸引されてロータ92の側壁面に接し、外リング94bとロータ92の側壁面との間に生じる摩擦力によって、アーマチュア94の外リング94bが回転する。
すると、板バネ94cを介して外リング94bに連結されている内リング94aも、外リング94bおよび板バネ94cと一体的に回転し、内リング94aに連結された回転軸51が回転し、コンプレッサ100は冷媒ガスGを圧縮する動作を行う。
(Function)
According to the compressor 100 of the present embodiment configured as described above, the pulley 91 and the rotor 92 are always rotated by the power input from the power source.
Here, when the electromagnetic coil 93 of the electromagnetic clutch 90 is not energized, the armature 94 does not contact with the rotor 92 and does not rotate, and therefore the compressor 100 does not perform the operation of compressing the refrigerant gas G.
On the other hand, when the electromagnetic coil 93 of the electromagnetic clutch 90 is energized, the outer ring 94b of the armature 94 is attracted to the electromagnetic coil 93 by the magnetic flux generated by the electromagnetic coil 93 and comes into contact with the side wall surface of the rotor 92. The outer ring 94b of the armature 94 is rotated by the frictional force generated between 94b and the side wall surface of the rotor 92.
Then, the inner ring 94a connected to the outer ring 94b via the plate spring 94c also rotates integrally with the outer ring 94b and the plate spring 94c, and the rotating shaft 51 connected to the inner ring 94a rotates, and the compressor 100 performs an operation of compressing the refrigerant gas G.

ここで、電磁コイル93の全体の重心は軸心Cであるが、周方向に沿った微小な部分の単位での重心は、コア93aの中心93gとなる。
このため、コア93aの部分ごとの重心である中心93gが、座面13に接していない状態であると、座面13が重心を支持していないため、その部分を安定して支持することができないおそれがあり、電磁コイル93の全体としてガタつきなどが生じるおそれがある。
Here, the center of gravity of the entire electromagnetic coil 93 is the axis C, but the center of gravity of each minute portion along the circumferential direction is the center 93g of the core 93a.
For this reason, when the center 93g, which is the center of gravity of each part of the core 93a, is not in contact with the seating surface 13, the seating surface 13 does not support the center of gravity, and thus the portion can be supported stably. There is a possibility that it cannot be performed, and there is a possibility that the entire electromagnetic coil 93 may be rattled.

しかし、本実施形態のコンプレッサ100は、座面13の一部である5つの部分13a,13b,13c,13d,13eが、コア93aの中心93gよりも半径方向の外側まで延びて形成されている。
これら5つの部分13a,13b,13c,13d,13eは、コア93aの部分ごとの重心である中心93gを支持することができ、電磁コイル93とハウジング10との間のガタつきの発生を防止乃至抑制することができる。
However, the compressor 100 of the present embodiment is formed such that the five portions 13a, 13b, 13c, 13d, and 13e, which are part of the seat surface 13, extend radially outward from the center 93g of the core 93a. .
