Abstract

<P>PROBLEM TO BE SOLVED: To provide an enclosed compressor equipped with a motor in which magnets can firmly and easily be set on a rotor and that totally improves its output efficiency by minimizing a distance between the electric steel plate of the rotor and a stator. <P>SOLUTION: The rotor 40 includes a stacked portion 42 structured with many stacked electric steel plates 41, magnets 43 arranged outside the stacked portion 42, and support plates 44, 45 arranged at the upper and bottom side of the stacked portion 42 and the magnets 43 respectively to fix these. By forming projections 44a, 45a that are inserted into the magnets 43 on the support plates 44, 45, the magnets 43 are prevented from being detached in the radial direction, which makes it unnecessary to provide a fixing member outside the magnets separately. This structure minimizes the distance between a stator that forms magnetic flux and the electric steel plate of the rotor, and effects the total improvement of the motor output efficiency and the compressor drive efficiency. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、密閉型圧縮機に関し、さらに詳細には、磁場を形成する固定子と電磁気的に相互作用しつつ回転運動をする回転子とを備えた密閉型圧縮機に関する。   The present invention relates to a hermetic compressor, and more particularly, to a hermetic compressor including a stator that forms a magnetic field and a rotor that rotates in an electromagnetic interaction.

一般に、密閉型圧縮機は、密閉空間内に冷媒を吸入し圧縮した後に吐出す装置であり、冷媒を圧縮する圧縮装置と、これを駆動させる駆動装置とから構成される。   In general, a hermetic compressor is a device that sucks and compresses refrigerant into a sealed space and then discharges the refrigerant. The hermetic compressor includes a compressor that compresses the refrigerant and a drive device that drives the compressor.

圧縮装置は、密閉空間を形成する密閉容器の内部に設けられるものであり、圧縮室を形成するシリンダーブロックと、圧縮室内を往復動するピストンと、を備え、シリンダーブロックの一側には、外部と連通する吸入室及び吐出室がそれぞれ形成されたシリンダーヘッドが結合される。   The compression device is provided inside a sealed container that forms a sealed space, and includes a cylinder block that forms a compression chamber, and a piston that reciprocates in the compression chamber. A cylinder head formed with a suction chamber and a discharge chamber communicating with each other is coupled.

駆動装置は、磁場を形成する固定子と、固定子と電気的に相互作用して回転する回転子と、回転子の中空部に挿入固定されて回転子とともに回転する回転軸を含むモータと、回転軸に連結されて回転運動を直線運動に変換することによってピストンを進退させるコンロッドとを備える。   The driving device includes a stator that forms a magnetic field, a rotor that rotates by electrical interaction with the stator, a motor that includes a rotating shaft that is inserted and fixed in a hollow portion of the rotor and rotates together with the rotor, And a connecting rod that is connected to the rotating shaft and moves the piston back and forth by converting the rotational motion into a linear motion.

一方、回転子は、回転軸の外側に積層される多数の電気鋼板と、電気鋼板の上端と下端をそれぞれ支持する１対の支持プレートと、電気鋼板の外側に配設されるマグネットと、を備え、電気鋼板の外周面側には、マグネットが嵌められて結合されるように嵌め溝が形成され、マグネットが嵌め溝から外されるのを防ぐべく、マグネットの外側にマグネットを取り囲む円筒部材が配設される。   On the other hand, the rotor includes a number of electrical steel plates stacked on the outside of the rotating shaft, a pair of support plates that respectively support the upper and lower ends of the electrical steel plate, and a magnet disposed on the outside of the electrical steel plate. A fitting groove is formed on the outer peripheral surface side of the electric steel sheet so that the magnet is fitted and coupled, and a cylindrical member surrounding the magnet is provided outside the magnet to prevent the magnet from being removed from the fitting groove. Arranged.

しかしながら、従来の密閉型圧縮機は、前記円筒部材により、磁束を形成する固定子と電気鋼板との間の距離が遠ざかることから、モータの出力効率が劣化してしまうという問題点があった。   However, the conventional hermetic compressor has a problem in that the output efficiency of the motor is deteriorated because the distance between the stator forming the magnetic flux and the electric steel sheet is increased by the cylindrical member.

しかも、別途の円筒部材が要求されるため、作業工程が複雑となり、コスト高となる問題点があった。   In addition, since a separate cylindrical member is required, there is a problem that the work process is complicated and the cost is increased.

本発明は、上記の問題点に鑑みてなされたものであり、回転子にマグネットを堅固で容易に設置できるし、回転子の電気鋼板と固定子との間の距離を最小限にすることによって出力効率を全体的に向上させうるモータを備えた密閉型圧縮機を提供することを目的とする。   The present invention has been made in view of the above problems, and can firmly and easily install a magnet on the rotor, and minimize the distance between the electric steel plate of the rotor and the stator. An object of the present invention is to provide a hermetic compressor including a motor that can improve the overall output efficiency.

上記の目的を達成すべく、本発明に係る密閉型圧縮機は、回転軸と、磁場を形成する固定子と電磁気的に相互作用しつつ前記回転軸と共に回転する回転子とを備えた密閉型圧縮機において、前記回転子は、多数の電気鋼板が積層されてなる積層部と、該積層部の外周面側に配設されたマグネットと、該マグネット及び前記積層部を軸方向に支持する支持プレートと、該マグネットを半径方向に支持するように、前記支持プレートから前記マグネットに向いて延設される固定突起とを含むことを特徴とする。   In order to achieve the above object, a hermetic compressor according to the present invention is a hermetic compressor including a rotating shaft and a rotor that rotates together with the rotating shaft while electromagnetically interacting with a stator that forms a magnetic field. In the compressor, the rotor includes a laminated portion in which a large number of electrical steel plates are laminated, a magnet disposed on the outer peripheral surface side of the laminated portion, and a support that supports the magnet and the laminated portion in the axial direction. It includes a plate and a fixing protrusion extending from the support plate toward the magnet so as to support the magnet in the radial direction.

好ましくは、前記固定突起は、前記マグネットの外側面を支持する。   Preferably, the fixing protrusion supports an outer surface of the magnet.

好ましくは、前記マグネットには、前記固定突起が挿入される固定溝が形成される。   Preferably, a fixing groove into which the fixing protrusion is inserted is formed in the magnet.

また、前記固定溝は、前記マグネットと前記支持プレートとが接する面に形成される。   The fixing groove is formed on a surface where the magnet and the support plate are in contact with each other.

また、前記固定突起は、前記マグネットの外側方向に傾斜して形成され、前記固定溝は、前記マグネットの外側面と前記支持プレートと接する面とが合う角部の一部が面取りされてなると好ましい。   Preferably, the fixing protrusion is formed to be inclined toward the outer side of the magnet, and the fixing groove is formed by chamfering a part of a corner where the outer surface of the magnet and the surface in contact with the support plate meet. .

上記のように構成される本発明に係る密閉型圧縮機は、回転子を構成する電気鋼板及びマグネットが、支持プレートに形成された固定突起にて互いに固定されるため、マグネットの外側に別途の固定部材を設けなくて済む。これにより、磁束を形成する固定子と回転子の電気鋼板との距離が最小限になり、モータの出力効率及び圧縮機の駆動効率が全体的に向上する効果を奏する。   In the hermetic compressor according to the present invention configured as described above, since the electric steel plate and the magnet constituting the rotor are fixed to each other by the fixing protrusion formed on the support plate, a separate outer side of the magnet is provided. There is no need to provide a fixing member. This minimizes the distance between the stator that forms the magnetic flux and the electrical steel plate of the rotor, and has the effect of improving overall motor output efficiency and compressor drive efficiency.

また、本発明に適用される回転子は、電気鋼板を固定する支持プレートによりマグネットが共に固定される仕組みとなっているため、作業工程及び生産コストを節減できる効果がある。   Further, the rotor applied to the present invention has a mechanism in which the magnets are fixed together by the support plate for fixing the electric steel sheet, and therefore, there is an effect that the work process and the production cost can be reduced.

以下、本発明による好ましい実施形態について、添付図面を参照しつつ詳細に説明する。   Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図１は、本発明に係る密閉型圧縮機の全体構造を示す側断面図である。本発明に係る密閉型圧縮機は、密閉空間を形成する密閉容器１０の内部に、冷媒を圧縮するように設けられた圧縮装置２０と、圧縮装置２０を駆動するための駆動装置３０とを含めて構成される。   FIG. 1 is a side sectional view showing the overall structure of a hermetic compressor according to the present invention. The hermetic compressor according to the present invention includes a compression device 20 provided so as to compress a refrigerant and a drive device 30 for driving the compression device 20 inside the hermetic container 10 forming a hermetic space. Configured.

圧縮装置２０は、圧縮室２１ａが形成されたシリンダーブロック２１と、圧縮室２１ａの内部を進退しつつ冷媒を圧縮するピストン２２とを備え、シリンダーブロック２１の一側には、外部と連通する吸入室２３ａ及び吐出室２３ｂがそれぞれ形成されたシリンダーヘッド２３が結合され、シリンダーブロック２１とシリンダーヘッド２３との間には、冷媒の流出入を制御するバルブ装置２４が設けられる。   The compression device 20 includes a cylinder block 21 in which a compression chamber 21a is formed, and a piston 22 that compresses refrigerant while moving forward and backward in the compression chamber 21a, and one side of the cylinder block 21 is a suction that communicates with the outside. A cylinder head 23 formed with a chamber 23 a and a discharge chamber 23 b is connected to each other, and a valve device 24 that controls the flow of refrigerant in and out is provided between the cylinder block 21 and the cylinder head 23.

駆動装置３０は、圧縮装置２０において冷媒の圧縮がなされるようにピストン２２を進退させるものであり、磁場を形成する固定子３１と、固定子３１の内部に、この固定子３１から離れて設置されるとともに、固定子３１と電磁気的に相互作用する回転子４０と、回転子４０の中心に嵌入されて回転子４０と共に回転する回転軸３２を含むモータと、回転軸３２に連結されて回転運動を直線運動に変換させることによって、ピストン２２を進退させるコンロッド３３とを含めて構成される。   The driving device 30 moves the piston 22 forward and backward so that the refrigerant is compressed in the compression device 20, and is installed in the stator 31 that forms a magnetic field, away from the stator 31. In addition, a rotor 40 that electromagnetically interacts with the stator 31, a motor including a rotating shaft 32 that is inserted into the center of the rotor 40 and rotates together with the rotor 40, and a rotating shaft 32 connected to the rotating shaft 32. By converting the motion into a linear motion, the connecting rod 33 is configured to move the piston 22 back and forth.

以下、本発明に適用された回転子３２を、図２ないし図５に基づき詳細に説明する。   Hereinafter, the rotor 32 applied to the present invention will be described in detail with reference to FIGS.

図２及び図３を参照すれば、本発明に適用される回転子４０は、多数の電気鋼板４１が上下方向に積層されてなる積層部４２と、積層部４２の外周面に形成された嵌め溝４２ａに嵌められるマグネット４３と、を備える。ここで、嵌め溝４２ａは、円周方向に沿って相互に離れて多数個形成され、各嵌め溝４２ａに嵌められるマグネット４３は、異なる極を持つように交互に設置される。   Referring to FIGS. 2 and 3, the rotor 40 applied to the present invention includes a laminated portion 42 in which a number of electrical steel plates 41 are laminated in the vertical direction, and a fitting formed on the outer peripheral surface of the laminated portion 42. And a magnet 43 fitted in the groove 42a. Here, a large number of the fitting grooves 42a are formed apart from each other along the circumferential direction, and the magnets 43 fitted in the fitting grooves 42a are alternately installed so as to have different poles.

そして、積層部４２の上側と下側にはそれぞれ上部支持プレート４４及び下部支持プレート４５が設けられて、積層部４２及びマグネット４３を軸方向に支持するが、このとき、多数の電気鋼板４１と支持プレート４４、４５は内部を貫通するリベット４６で互いに固定される。   An upper support plate 44 and a lower support plate 45 are respectively provided on the upper side and the lower side of the laminated portion 42 to support the laminated portion 42 and the magnet 43 in the axial direction. The support plates 44 and 45 are fixed to each other by a rivet 46 penetrating the inside.

また、上部支持プレート４４には、マグネット４３が半径方向に離脱するのを防ぐべく、マグネット４３の上面に凹設された上部固定溝４３ａに挿入される上部固定突起４４ａが突出形成される。そして、下部支持プレート４５には、マグネット４３の下面に向いて突出された下部固定突起４５ａが形成され、下部固定突起４５ａが挿入される下部固定溝４３ｂが、マグネット４３の下面に形成される。   In addition, the upper support plate 44 is formed with an upper fixing protrusion 44a that is inserted into an upper fixing groove 43a that is recessed in the upper surface of the magnet 43 so as to prevent the magnet 43 from separating in the radial direction. The lower support plate 45 is formed with a lower fixing protrusion 45 a protruding toward the lower surface of the magnet 43, and a lower fixing groove 43 b into which the lower fixing protrusion 45 a is inserted is formed on the lower surface of the magnet 43.

また、図４及び図５に示すように、上部固定突起４４ａ'及び下部固定突起４５ａ'は、マグネット４３'の外側面を支持するように設けられてもいいが、このとき、固定突起４４ａ'、４５ａ'がマグネット４３'の外側へ突き出るのを防ぐべく、固定突起４４ａ'、４５ａ'は、マグネット４３'の外側方向に所定角度だけ傾斜して形成される。そして、上部固定溝４３ａ'は、マグネット４３'の上面と外側面とが合う角部の一部が面取りされてなるし、下部固定溝４３ｂ'は、マグネット４３'の下面と外側面とが合う角部の一部が面取りされてなる。   4 and 5, the upper fixing protrusion 44a ′ and the lower fixing protrusion 45a ′ may be provided so as to support the outer surface of the magnet 43 ′. At this time, the fixing protrusion 44a ′. , 45a ′ are formed so as to be inclined by a predetermined angle in the outer direction of the magnet 43 ′ in order to prevent the outer projection of the magnet 43 ′. The upper fixing groove 43a ′ is formed by chamfering a part of the corner where the upper surface and the outer surface of the magnet 43 ′ meet, and the lower fixing groove 43b ′ is aligned with the lower surface and the outer surface of the magnet 43 ′. Part of the corner is chamfered.

次に、本発明に係る密閉型圧縮機の回転子の組立過程及びそれによる効果について説明する。   Next, the assembly process of the rotor of the hermetic compressor according to the present invention and the effects thereof will be described.

まず、多数の電気鋼板４１をリベット４６に嵌めて積層部４２を形成する。次いで、リベット４６の上側に上部支持プレート４４を挿入し、リベット４６の下側に下部支持プレート４５を挿入するが、このとき、積層部４２の外周面側に形成された嵌め溝４２ａにマグネット４３を嵌めつつ支持プレート４４、４５に形成された固定突起４４ａ、４５ａとマグネット４３の固定溝４３ａ、４３ｂとの位置を互いに一致させた後に支持プレート４４、４５を積層部４２及びマグネット４３と完全に結合させる。   First, a large number of electrical steel plates 41 are fitted into rivets 46 to form the laminated portion 42. Next, the upper support plate 44 is inserted above the rivet 46 and the lower support plate 45 is inserted below the rivet 46. At this time, the magnet 43 is inserted into the fitting groove 42 a formed on the outer peripheral surface side of the laminated portion 42. The fixing projections 44a and 45a formed on the support plates 44 and 45 and the fixing grooves 43a and 43b of the magnet 43 are made to coincide with each other while the support plates 44 and 45 are completely aligned with the laminated portion 42 and the magnet 43. Combine.

その後、別途の治具にてリベット４６をコーキングすると、マグネット４３は支持プレート４４、４５により積層部４２にしっかり固定される。   Thereafter, when the rivet 46 is caulked with a separate jig, the magnet 43 is firmly fixed to the laminated portion 42 by the support plates 44 and 45.

このように、本発明に係る密閉型圧縮機の回転子４２は、マグネット４３が支持プレート４４、４５だけでしっかり固定されるため、従来の圧縮機と違い、マグネット４３の外周面を囲んで固定する別途の円筒部材が不要になる。   As described above, the rotor 42 of the hermetic compressor according to the present invention is fixed around the outer peripheral surface of the magnet 43 unlike the conventional compressor because the magnet 43 is firmly fixed only by the support plates 44 and 45. This eliminates the need for a separate cylindrical member.

これにより、磁束を形成する固定子３１と回転子４０の電気鋼板４１との距離を最小限にでき、結果としてモータの出力効率を向上させることができる。   Thereby, the distance of the stator 31 which forms magnetic flux, and the electrical steel plate 41 of the rotor 40 can be minimized, As a result, the output efficiency of a motor can be improved.
