Abstract:
(EN) This scroll compressor is provided with a bush including: a shaft portion disposed between an orbiting bearing that supports an orbiting scroll and an eccentric pin of a crankshaft; and a balance weight portion secured by shrink-fitting to the outer circumference of the shaft portion. The shaft portion is provided with: a cylindrically shaped main body portion which is fitted into the orbiting bearing and into which the eccentric pin of the crankshaft is inserted; and a cylindrically shaped linking portion which extends outward from the end portion, in the axial direction, of the main body portion, and to which the balance weight portion is joined. Furthermore, the bush satisfies the following conditions (a) and (b). (a) 1.2 ≤ D2/D1 ≤ 1.6 (b) 1.0 ≤ (D2-D3)/(D4-D2)×E1/E2 ≤ 3.5 Where D1: external diameter of main body portion, D2: external diameter of linking portion, D3: internal diameter of main body portion, D4: external diameter of balance weight portion, E1: Young's modulus of shaft portion, E2: Young's modulus of balance weight portion
(FR) L'invention concerne un compresseur à spirale équipé d'une douille comprenant : une partie arbre disposée entre un palier orbital qui supporte une spirale orbitale et une goupille excentrique d'un vilebrequin ; et une partie contrepoids fixée par ajustement par contraction à la circonférence externe de la partie arbre. La partie arbre est pourvue : d'une partie corps principal de forme cylindrique qui est ajustée dans le palier orbital et dans laquelle la goupille excentrique du vilebrequin est insérée ; et d'une partie de liaison de forme cylindrique qui s'étend vers l'extérieur depuis la partie d'extrémité, dans la direction axiale, de la partie corps principal, et à laquelle la partie contrepoids est assemblée. De plus, la douille répond aux conditions (a) et (b) suivantes. (a) 1,2 ≤ D2/D1 ≤ 1,6 (b) 1,0 ≤ (D2-D3)/(D4-D2)×E1/E2 ≤ 3,5 où D1 : diamètre extérieur de la partie corps principal, D2 : diamètre extérieur de la partie de liaison, D3 : diamètre intérieur de la partie corps principal, D4 : diamètre extérieur de la partie contrepoids, E1 : module d'Young de la partie arbre, E2 : module d'Young de la partie contrepoids
(JA)  スクロール圧縮機は、揺動スクロールを支持する揺動軸受とクランクシャフトの偏心ピンとの間に配置された軸部と、軸部の外周に焼嵌固定されたバランスウェイト部とを有するブッシュを備える。軸部は、揺動軸受に嵌め込まれ、且つクランクシャフトの偏心ピンが挿入される円筒形状の本体部と、本体部の軸方向の端部から外方に延出し、バランスウェイト部が接合される円筒形状の連結部とを備える。そして、ブッシュは、以下の(a)、(b)の条件を満たす。 (a)1.2≦D2/D1≦1.6 (b)1.0≦(D2-D3)/(D4-D2)×E1/E2≦3.5 ここで、D1:本体部の外径、D2:連結部の外径、D3:本体部の内径、D4:バランスウェイト部の外径、E1:軸部のヤング率、E2:バランスウェイト部のヤング率
