ROTARY COMPRESSOR VANE AND MANUFACTURE THEREOF

摘要

PURPOSE: To provide a manufacturing method enabling the abrasion resistance of a rotary compressor rotor material to be improved, and allowing the mass production of a rotary compressor vane having high reliability and capability of service life extension as well as a vane slide member of high abrasion resistance at a good yield and low cost. CONSTITUTION: A vane base material 28 is internally provided with an oiling port 31 for feeding lubricating oil to n approximately 25μm gap formed between a rotary slide member 29 formed on a vane tip and a recess 30 of circular arc cross section for housing the member 29. The port 31 has a diameter of 1mm and penetrates a vane from the lower section thereof to the surface of the recess 30 where the vane tip has a circular arc cross section. Also, the rotatable member 29 after formed on the vane tip is kept rotating and in this rotating state, a ceramic protective film is formed on the surface of the member 29.
