Title (EN) SCROLL COMPRESSOR
(FR) COMPRESSEUR À SPIRALE
(JA) スクロール圧縮機
Abstract:
(EN) A scroll compressor of which the operational noise is prevented from increasing by reducing impact sound of an Oldham’s ring. Assuming the width at an Oldham’s ring (57) key portion of iron based material is t, and the width of a turning-side key way (19) in the back of the end plate (12a) of a turning scroll (12) of aluminum based material and the width of a fixed-side key way (32) in the thrust face side of a main bearing member (51) of aluminum based material is s, a gap d occurring by s-t is set to satisfy a relation (6×10-5)≤d/L≤(3.5×10-4) for the key pitch L of the Oldham’s ring (57). Since collision force against the key way is weakened even if the key of the Oldham’s ring (57) vibrates in the key way, impact sound of the Oldham’s ring is reduced and thereby operational noise of the scroll compressor is reduced.
(FR) La présente invention concerne un compresseur à spirale dont l’accroissement du bruit de marche est évité par réduction du bruit d’impact d’une bague d’Oldham. En supposant que la largeur d’une clavette en matériau à base de fer d’une bague d’Oldham (57) est t et que la largeur d’un logement de clavette à sens de rotation (19) au dos de la plaque d’extrémité (12a) d’une spirale rotative (12) en matériau à base d’aluminium et la largeur d’un logement de clavette à sens fixe (32) sur l’intrados d’un palier principal (51) en matériau à base d’aluminium sont s, un espace d résultant de la différence s-t est défini afin de satisfaire une relation (6×10-5) ≤ d/L ≤ (3.5×10-4) pour le pas de clavette L de la bague (57). Comme la force de collision contre le logement de clavette est atténuée même si la clavette de la bague d’Oldham (57) vibre dans le logement, le bruit d’impact de la bague est réduit, ce qui permet de diminuer le bruit de marche du compresseur à spirale.
(JA)  オルダムリングの衝撃音を小さくし、スクロール圧縮機の運転騒音の増大を防止すること。  鉄系材料のオルダムリング57キー部の巾をtとし、アルミニウム系材料の旋回スクロール12の鏡板12a背面の旋回側キー溝19の巾およびアルミニウム系材料の主軸受部材51のスラスト面側の固定側キー溝32の巾をsとしたとき、s-tで生ずる隙間dをオルダムリング57のキーピッチLに対して、(6×10-5)≦d/L≦(3.5×10-4)に設定したもので、これによって、オルダムリング57のキーがキー溝内で振動してもキー溝との衝突力が弱まり、オルダムリングの衝撃音が小さくなりスクロール圧縮機の運転騒音の低減が図られる。
