LUBRICATING DEVICE FOR BEARING INSTALLED ONTO ECCENTRIC BODY SHAFT IN BEARING OF COMPRESSOR BODY OF GYRATING MASS, PARTICULARLY SPIRAL TYPE SUPERCHARGER

摘要

PURPOSE: To fill a lubrication medium tank simply even after a compressor is assembled by providing a passage provided on at least one guide shaft in the lubrication medium tank in a lubrication device. CONSTITUTION: Casing bearings 13, 14 are formed to prevent a leakage of lubrication medium by an elastic packing 15. A lubrication medium passage consisting of both regions 16a and 16b is provided in a guide shaft 5 to enlarge a lubrication medium tank. The passage 16 is continuous with an end face of a guide shaft 5 on the left side and is closed using an ordinary packing by a screw 19 there. Consequently, the whole lubrication medium tank formed by the passage 16 and a space 12 is filled with lubrication medium after a spiral type supercharger is assembled to enable additional filling during operation.
