COMPRESSOR

COMPRESSOR

A compressor (1) prevents lubrication oil from leaking from a lower end of a bearing (3) and flowing out from a casing (5). The compressor (1) includes a compression mechanism (7), a drive shaft (11), a bearing (3) for the drive shaft (11), and an oil supply passage (29) configured to supply lubrica...

Zusammenfassung:A compressor (1) prevents lubrication oil from leaking from a lower end of a bearing (3) and flowing out from a casing (5). The compressor (1) includes a compression mechanism (7), a drive shaft (11), a bearing (3) for the drive shaft (11), and an oil supply passage (29) configured to supply lubrication oil to a clearance between the drive shaft (11) and the bearing (3). The drive shaft (11) includes a large-diameter shaft part (11f) supported by the bearing (3), and a small-diameter shaft part (11g) connected to a lower end part of the large-diameter shaft part (11f). A sealing part (10) configured to reduced or prevent oil leakage from the bearing (3) includes an oil receiving surface (26) facing a circular stepped surface (12) formed at a boundary between the large-diameter shaft part (11f) and the small-diameter shaft part (11g) and being apart from the stepped surface (12) with a clearance.
