LUBRICATING DEVICE FOR ANTI-ROTATION ASSEMBLY OF SCROLL COMPRESSOR, IMPROVED LUBRICATING DEVICE, AND SCROLL COMPRESSOR INCLUDING ANTI-ROTATION DEVICE AND IMPROVED LUBRICATING DEVICE FOR ANTI-ROTATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a novel and inventive lubricating mechanism capable of regularly lubricating an anti-rotation device disposed on a scroll compressor from a point easy to be seen and positioned outside of a bearing cap for the scroll compressor. SOLUTION: At least one of an anti-rotation assembly 90 is provided in order to prevent relative rotation between an orbital motion scroll member 36 and a still scroll member 37 of the scroll compressor. The anti-rotation assembly 90 includes a first rotating bearing member 92 mounted in a housing, a second rotating bearing member 94 mounted on the orbital motion scroll member 36, and an offset crank member 100 for mutually connecting the first and the second bearing members, and is lubricated through a lubricating oil channel 122. The lubricating oil channel goes through the first rotating bearing member 92 from a lubricating oil port 120 outside of the housing and then goes through a channel 124 provided in the offset crank member 100. Thus, the lubricant can be supplied to the second rotating bearing member 94.
