Description
Technical field
The present invention relates to a kind of interior scroll compressors such as air conditioner refrigerating device that are arranged on.
Background technique
In recent years, in refrigeration and air condition compressor, owing to comprising the range of operation expansion of rotating speed, pressure etc. and the appearance of central air-conditioner, needed consumingly high reliability.Especially in central air-conditioner, owing to being sealed in the amount of air conditioner inner refrigerant gas, increase, a large amount of refrigerant gas dissolves in the lubricant oil for slidingsurface between lubricated rotatingshaft and axle supporting portion, so the viscosity of lubricant oil is extremely declined, cause in lubricated path and cause bad lubricating with bearing part is instantaneous owing to forming refrigeration agent bubble, and may cause the bearing damage of steady supporting rotatingshaft.
As for supporting the bearing of the rotatingshaft of refrigeration and air condition compressor, conventionally use with lower bearing: wherein the Oilite bronze base alloy that is impregnated with graphite on backing metal is that sintering forms and allow Oilite bronze base alloy and graphite to be sparsely exposed to respect to the bearing on the slidingsurface of rotatingshaft (referring to patent documentation 1); By the bearing as rolling lining that sheet metal rolling-forming is made, sheet metal has the surface layer of tool lubricity and wear resistance on the slidingsurface with respect to rotatingshaft, make surface layer be placed in inner side, the sheet metal with this surface layer is to have the steel plate (referring to patent documentation 2) of porous sintered layer of making by being impregnated with teflon (being designated hereinafter simply as PTFE) and plumbous bronze powder; Wherein the Oilite bronze base alloy that is impregnated with the composite material being comprised of synthetic resin and lubriation material on backing metal is that sintering forms and allow Oilite bronze base alloy and composite material to be sparsely exposed to respect to the bearing on the contact surface of axle (referring to patent documentation 3); And comprise the porous layer being arranged in metal base and be immersed in the bearing of the fluororesin layer in porous layer, and wherein make the finished surface that grinds that sinter layer exposes from fluororesin layer be used as bearing slidingsurface (with reference to patent documentation 4).
