Abstract
(EN)
A hermetic refrigerant compressor (100) stores, in a hermetic container (101), a lubricating oil (103) that has a kinematic viscosity at 40°C of 1-9 mm2/S and includes sulfur or a sulfur-containing compound as a slidability modifier. A compression element (107) includes a crankshaft (108) as a shaft. Where the sliding surface of a main shaft (109) is a single surface and the axial length of the sliding surface is taken as a single sliding length L, or where the sliding surface is divided into a plurality of surfaces and the minimum axial length of the sliding surface is taken as the single sliding length L, the ratio L/D between the single sliding length L and the outer diameter D of the main shaft (109) is 0.51 or less. Furthermore, where the sum total of axial lengths of the plurality of sliding surfaces is taken as the total sliding length Lt, the ratio Lt/D between the total sliding length Lt and the outer diameter D may be 1.26 or less.
(FR)
L'invention concerne un compresseur de réfrigérant hermétique (100) qui stocke, dans un récipient hermétique (101), une huile lubrifiante (103) qui a une viscosité cinématique à 40 °C de 1-9 mm2/S et comprend du soufre ou un composé contenant du soufre en tant que modificateur de glissement. Un élément de compression (107) comprend un vilebrequin (108) en tant qu'arbre. La surface coulissante d'un arbre principal (109) est une surface unique et la longueur axiale de la surface coulissante est prise sous la forme d'une seule longueur de coulissement L, ou où la surface coulissante est divisée en une pluralité de surfaces et la longueur axiale minimale de la surface coulissante est prise en tant que longueur de coulissement unique L, le rapport L/D entre la longueur de coulissement unique L et le diamètre externe D de l'arbre principal (109) est de 0,51 ou moins. En outre, lorsque la somme totale des longueurs axiales de la pluralité de surfaces coulissantes est prise en tant que longueur de coulissement totale Lt, le rapport Lt/D entre la longueur de coulissement totale Lt et le diamètre externe D peut être de 1,26 ou moins.

密閉型冷媒圧縮機(100)は、密閉容器(101)内に、40℃での動粘度が1~9mm2 /Sであって、硫黄または硫黄を有する化合物を摺動性改質剤として含有する潤滑油(103)を貯留する。圧縮要素(107)は、軸部としてクランクシャフト(108)を備える。主軸(109)の摺動面が単一面である場合には、当該摺動面の軸方向長さを単一摺動長さLとしたとき、または、摺動面が複数の面に分割される場合には、摺動面の最少の軸方向長さを単一摺動長さLとしたときに、単一摺動長さLと主軸(109)の外径Dとの比率L/Dが0.51以下である。さらに、複数の摺動面の軸方向長さの合計を全摺動長さLtとしたときに、全摺動長さLtと外径Dとの比率Lt/Dが1.26以下であってもよい。
