Description
本発明は、業務用または家庭用、あるいは乗り物用の冷凍空調、あるいはヒートポンプ式の給湯システムなどに用いられるスクロール圧縮機に関するものである。 TECHNICAL FIELD The present invention relates to a scroll compressor used in a refrigeration air conditioner for business use, household use, or vehicle use, or a heat pump type hot water supply system.
従来、この種のスクロール圧縮機は、固定スクロールと旋回スクロールの鏡板との対向面に環状のシール部と前記シール部の外側に位置する環状の凹部を設けた構成をとっていた（例えば、特許文献１参照）。 Conventionally, this type of scroll compressor has a configuration in which an annular seal portion and an annular recess located outside the seal portion are provided on the opposed surfaces of the fixed scroll and the end plate of the orbiting scroll (for example, a patent) Reference 1).
図３は、特許文献１に記載されたスクロール圧縮機を示すものである。図１は図３に示された固定スクロール５を示すものである。図１に示すように、固定スクロール５の渦巻状ラップ２１外まわりにある、旋回スクロール（図示せず）の鏡板と対向面に、渦巻状ラップ２１の最外周の内壁面１５ａ〜１５ｄにほぼ沿った外壁面１６を持つように広がり旋回スクロールの鏡板と摺接する環状シール部１３と、シール部１３の外側に位置する環状凹部７から構成されている。従来この環状凹部７の加工にはボールエンドミル等の工具を用いて加工を行ってきた。 FIG. 3 shows a scroll compressor described in Patent Document 1. As shown in FIG. FIG. 1 shows the fixed scroll 5 shown in FIG. As shown in FIG. 1, the outer peripheral surface of the spiral wrap 21 is substantially along the outer circumferential surface of the spiral wrap 21 on the surface facing the end plate of the orbiting scroll (not shown) around the spiral wrap 21 of the fixed scroll 5. An annular seal portion 13 which spreads to have an outer wall surface 16 and comes into sliding contact with the end plate of the orbiting scroll and an annular recess portion 7 located outside the seal portion 13 are configured. Conventionally, the annular recess 7 has been processed using a tool such as a ball end mill.
しかしながら、前記従来の構成における環状凹部７は、幅が一定ではなく加工残りを無くすためには数パスの加工経路を通る必要があった。これは環状凹部深さが全周で一定である必要性があるためである。加工効率の高速化を行うためには加工経路の簡略化が大きく関係してくる。しかし、加工経路の簡略化を行うことで、加工残りが発生し、旋回スクロールの鏡板と摺接し、摺動損失が発生するという問題があった。 However, the annular recess 7 in the conventional configuration has a constant width and has to pass through several machining paths in order to eliminate machining residue. This is because the annular recess depth needs to be constant over the entire circumference. In order to increase the processing efficiency, simplification of the processing path is greatly related. However, by simplifying the machining path, there is a problem that a machining residue is generated and is in sliding contact with the end plate of the orbiting scroll, resulting in a sliding loss.
そこで本発明は、前記従来の課題を改善するもので、加工効率の高速化を行いかつ、旋回スクロールの鏡板との摺動損失を抑えることを達成したスクロール圧縮機を提供することを目的とする。 SUMMARY OF THE INVENTION Accordingly, the present invention is intended to improve the above-described conventional problems, and to provide a scroll compressor that achieves high processing efficiency and suppresses sliding loss with the end plate of the orbiting scroll. .
前記従来の課題を解決するために、本発明のスクロール圧縮機は固定スクロール５に設けた環状凹部最大幅７ｂの寸法を環状凹部最小幅７ａの２倍より小さくし、環状凹部７をボールエンドミルによって加工したものである。 In order to solve the above-mentioned conventional problems, the scroll compressor of the present invention is configured such that the size of the annular recess maximum width 7b provided in the fixed scroll 5 is smaller than twice the annular recess minimum width 7a, and the annular recess 7 is formed by a ball end mill. It has been processed.
本実施の形態によれば環状凹部最大幅７ｂを環状凹部最小幅７ｂの２倍より小さくすることで１往復の加工経路にて全てを加工でき、かつボールエンドミルによる加工で加工残りが環状シール部１３より高くなることを防ぎ、旋回スクロール鏡板との摺接および摺接によるオイル切りを抑制することを実現することができる。 According to the present embodiment, by making the annular recess maximum width 7b smaller than twice the annular recess minimum width 7b, all can be processed in one reciprocating processing path, and the processing residue by the ball end mill is the annular seal portion. It is possible to prevent the oil from becoming higher than 13, and to prevent sliding contact with the orbiting scroll end plate and oil drainage due to sliding contact.
本発明の前記環状凹部幅決定法を採用することにより、加工効率の高速化と、加工効率向上によって発生する加工残りが旋回スクロールの摺動に影響を与えない事を両立した固定スクロールを使用したスクロール圧縮機を提供することが出来る。 By adopting the annular recess width determining method of the present invention, a fixed scroll is used which achieves both high processing efficiency and that the processing residue generated by the improvement in processing efficiency does not affect the sliding of the orbiting scroll. A scroll compressor can be provided.
第１の発明は固定スクロールの渦巻状のラップ外まわりにある、旋回スクロールの鏡板と対向面に、渦巻状のラップの最外周の内壁面にほぼ沿った外壁面を持つように広がり旋回スクロールの鏡板と摺接する環状のシール部の外側に位置する環状の凹部に関するものである。 1st invention spreads out so that it may have the outer wall surface which followed the inner peripheral wall surface of the outermost periphery of a spiral-shaped wrap in the surface facing the rotating scroll's mirror plate in the outer periphery of the spiral-shaped wrap of a fixed scroll. It is related with the cyclic | annular recessed part located in the outer side of the cyclic | annular seal part which slidably contacts.
前記環状の凹部は凹部の幅が一定ではなく、狭い箇所と広い箇所に分けられ、狭い箇所と凹部の深さによって加工工具であるボールエンドミルの工具径を決定する。この工具径により、凹部の広い箇所は数パスの加工が必要であるが、前記の方法によって決定した工具径より凹部の広い箇所の寸法を決定することで、加工パス数を２パス以内に抑えた加工が行えるものである。ボールエンドミルの１パスによって加工できる幅をｄ、凹部の幅をＷｍｉｎ〜Ｗｍａｘとした場合Ｗｍｉｎ＝ｄでかつｄ＜Ｗｍａｘ＜２ｄと決定したものである。このとき前記環状凹部の最大深さは凹部の幅に関係なく一定であるものとする。 The annular recess is not constant in width, and is divided into a narrow portion and a wide portion, and the tool diameter of a ball end mill as a processing tool is determined by the narrow portion and the depth of the recess. Depending on the tool diameter, processing of several passes is necessary for wide recesses, but by determining the dimensions of the recesses wider than the tool diameter determined by the above method, the number of processing passes can be suppressed to within 2 passes. Can be processed. When the width that can be processed by one pass of the ball end mill is d and the width of the recess is Wmin to Wmax, Wmin = d and d <Wmax <2d. At this time, the maximum depth of the annular recess is constant regardless of the width of the recess.
第２の発明は第１の発明における環状凹部の加工に用いる工具をボールエンドミルではない、先端に曲率を持つエンドミルにて加工を行うものである。エンドミル先端の曲率を変えることにより、環状凹部の深さに合わせた加工を行うことが出来、環状凹部の幅の選択肢が広がる。 In the second invention, the tool used for processing the annular recess in the first invention is processed by an end mill having a curvature at the tip, not a ball end mill. By changing the curvature of the end mill tip, processing according to the depth of the annular recess can be performed, and the choice of the width of the annular recess is expanded.
第３の発明は第１及び第２の発明における環状のシール部の幅を固定スクロールの渦巻きラップの厚さの半分以上大きくしたものである。これにより、環状シール部の幅を可能な限り小さく抑えて摺動損失を極力低減しながら、必要なシール幅を確実に満足することが出来る。 In the third invention, the width of the annular seal portion in the first and second inventions is made larger than half the thickness of the spiral wrap of the fixed scroll. As a result, it is possible to reliably satisfy the required seal width while keeping the width of the annular seal portion as small as possible and reducing the sliding loss as much as possible.
第４の発明は第１〜第３の発明における環状凹部深さを固定スクロール部品のラップ溝深さを、０．１ｍｍ以上、かつ固定スクロール部品のラップ溝深さＨの１／５以下としたものである。０．１ｍｍ以上とすることにより旋回スクロールの摺動面においてオイル等による粘性損失を防ぎ、固定スクロール部品のラップ溝深さＨの１／５以下とすることで強度や加工性の低下を回避することが出来る。 In the fourth invention, the depth of the annular recess in the first to third inventions is set such that the wrap groove depth of the fixed scroll component is 0.1 mm or more and 1/5 or less of the wrap groove depth H of the fixed scroll component. Is. By setting it to 0.1 mm or more, viscosity loss due to oil or the like is prevented on the sliding surface of the orbiting scroll, and by reducing it to 1/5 or less of the lap groove depth H of the fixed scroll component, deterioration in strength and workability is avoided. I can do it.
第５の発明は第１〜４の発明における環状凹部の外周が旋回スクロールの旋回半径よりも外側としたものである。環状凹部の外周を旋回スクロールの旋回半径よりも外側とすることにより、固定スクロールと旋回スクロール摺動部に異物が噛み込んだ場合、前記異物が環状凹部へ排出されることで、環状シール部の密着性が高まり、圧縮室への冷媒の漏れを防止することができる。 The fifth invention is such that the outer periphery of the annular recess in the first to fourth inventions is outside the turning radius of the orbiting scroll. By making the outer periphery of the annular recess outside the turning radius of the orbiting scroll, when foreign matter is caught in the fixed scroll and the orbiting scroll sliding portion, the foreign matter is discharged into the annular recess, so that the annular seal portion Adhesion is enhanced and leakage of the refrigerant into the compression chamber can be prevented.
以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
