Document Type and Number:
WIPO Patent Application WO/2016/155806
Kind Code:
A1
Abstract:
The present invention relates to a crankshaft (1) for use in a hermetic compressor (2) comprising a bearing (3), a rotor (4) and a lubricant sump (5). The crankshaft (1) comprises a journal (7), an inner diameter surface (6a) for conveying the lubricant to the journal (7), a lubricant outlet (8) which is formed into the journal (7) and opens into the inner diameter surface (6a) of the crankshaft (1) and an outer diameter surface (6b) for the attachment to the rotor (4). In the crankshaft (1) of the present invention the shaft (6) comprises an axially extending slot (9) for conveying the lubricant from the sump (5) to the journal (7) upon rotation. The slot (9) fluidly connects, in the radial direction, the inner diameter surface (6a) to the outer diameter surface (6b) of the shaft (6). At least part of the slot (9) radially faces the innermost diameter surface (4a) of the rotor (4).
