Scroll compressor

Abstract

Abstract PURPOSE:To improve the lubricating property of a bearing metal by a method wherein oil feeding grooves are provided on the bearing metal, supporting an oscillating scroll shaft, and the outer peripheral surface of the tip end of a crank shaft while respective oil feeding grooves are communicated with each other through an oil hole. CONSTITUTION:The bearing metal 36 is provided with the oil groove 63 for feeding the oil while the outer peripheral suface of the large diametral part 66 of the crank shaft is provided with the oil groove 62 at the opposite side of the load for the crank shaft. Further, oil holes, connected to the oil grooves 62, 63, are provided at two places and one of them penetrates the center shaft of the crank shaft 6 and can feed the oil to the part 68 engaging with the shaft. The load is acting in the same angular direction at all times, therefore, a stabilized oil feeding performance may be obtained.
