HERMETIC REFRIGERANT COMPRESSOR AND FREEZING/REFRIGERATING APPARATUS IN WHICH SAME IS USED
Lubricating oil has a kinematic viscosity in a range of 1 mm2/S to 7 mm2/S at 40°C, has a mass average molecular weight in a range of 150 to 400, and contains 0.5% by mass or more of a high molecular weight component. The high molecular weight component has a mass molecular weight of greater than or...

| description | Lubricating oil has a kinematic viscosity in a range of 1 mm2/S to 7 mm2/S at 40°C, has a mass average molecular weight in a range of 150 to 400, and contains 0.5% by mass or more of a high molecular weight component. The high molecular weight component has a mass molecular weight of greater than or equal to 500. A crankshaft serving as a shaft part of a compression element includes a main shaft that includes a sliding surface. In a case where the sliding surface is a single sliding surface, a length of the single sliding surface in an axial direction is a single sliding length L, whereas in a case where the sliding surface is divided into a plurality of sliding surfaces, a length of one of the sliding surfaces in the axial direction, the one sliding surface having a least length in the axial direction among the plurality of sliding surfaces, is the single sliding length L, and a ratio L / D of the single sliding length L to an external diameter D of the main shaft is less than or equal to 2.0. |
