REFRIGERANT COMPRESSOR AND REFRIGERATION/COLD STORAGE APPLIANCE IN WHICH SAME IS USED

A refrigerant compressor (100) reserves lubricating oil (103) having kinetic viscosity of 0.1 to 5.1 mm/S at 40 C in a sealed container (101), and accommodates therein an electric component (106), and a compression component (107). The compression component (107) includes: as a shaft portion, a cran...

Beschreibung
Zusammenfassung:	A refrigerant compressor (100) reserves lubricating oil (103) having kinetic viscosity of 0.1 to 5.1 mm/S at 40 C in a sealed container (101), and accommodates therein an electric component (106), and a compression component (107). The compression component (107) includes: as a shaft portion, a crank shaft (108) including a main shaft (109) and an eccentric shaft (110); and as a bearing portion, a main bearing (114) supporting the main shaft (109) and an eccentric bearing (119) supporting the eccentric shaft (110). A treated surface, such as an oxide film, having hardness equal to or more than hardness of the bearing portion (the main bearing (114) or the eccentric bearing (119)) is formed on at least one of a surface of the main shaft (109) and a surface of the eccentric shaft (110). With this, even when lubricating oil having low viscosity is used, satisfactory reliability can be realized at a sliding portion.
