Abstract

PURPOSE: To lubricate stably an eccentric bearing section even in start after long time stoppage of running by forming a shaft portion oil reservoir in a communicating hole outlet for lubricating oil provided in the eccentric bearing section of a crankshaft.
CONSTITUTION: A communicating port 23 provided on an eccentric bearing 11 section of a crankshaft 5 of a scroll compressor is formed on the outlet with a projection 27 to provide a bearing portion oil reservoir 28 opening to the eccentric bearing 11. When the compressor is driven, lubricating oil in a lubricating oil reservoir 22 on the bottom of enclosed container flows through the communicating port 23 by an oiling pump provide on the lower portion of crankshaft 5. Along with this lubricating oil flow is lubricated the eccentric bearing 11 section first by lubricating oil previously remaining in the bearing portion oil reservoir 28. As a result, the compressor can be stably lubricated even in start after a long time rest so that the reliability of compressor is improved.
