Abstract

A coating solution that contains 10 to 20% by weight of epoxy resin serving as a thermosetting resin, 20 to 30% by weight of MoS2, and 5 to 10% by weight of graphite, with a remainder thereof constituted by an organic solvent, is sprayed onto a wrap portion side face of an orbiting scroll from a spray nozzle . While spraying the coating solution, the orbiting scroll is rotated on a rotating table and the spray nozzle is moved along a rectilinear movement path toward a radial direction outer side of the orbiting scroll while maintaining an attitude thereof from the start of the spraying process. After applying the coating solution, the coating solution is dried by baking, whereupon a break-in operation is performed. As a result, an elastic coating is formed at a coating thickness that enables elastic deformation in accordance with a clearance between the wrap portion side faces.

Description

RELATED APPLICATIONS

[0001] The present application is a continuation of International Application Number PCT / JP2011 / 077753, filed Dec. 1, 2011, and claims priority from Japanese Application Number 2011-006386, filed Jan. 14, 2011. The above listed applications are hereby incorporated by reference in their entirety.TECHNICAL FIELD

[0002] The present invention relates to a scroll type fluid machine, and a method and a device for forming an elastic coating thereon, with which an elastic coating can be formed on a side face of a spiral wrap forming the scroll type fluid machine while preventing seizure, galling, wear, and contact damage on the wrap portion side face.BACKGROUND ART

[0003] A scroll type fluid machine is used as a scroll type compressor, a scroll type vacuum pump, a scroll type expander, a scroll type air blower, and the like. A scroll type fluid machine is constituted by a fixed scroll and an orbiting scroll having spiral wrap portions that stand upright on end plates thereof,...
