Title:
SCROLL COMPRESSOR AND DRIVING SHAFT AND UNLOADING BUSH FOR SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2016/169349
Kind Code:
A1
Abstract:
A scroll compressor comprises a compressing mechanism (10) for compressing working fluid and a driving shaft (30) for driving the compressing mechanism (10). The driving shaft (30) comprises an eccentric crank pin (32). An unloading bush (42) is arranged between the compressing mechanism (10) and the eccentric crank pin (32), so that the eccentric crank pin (32) drives the compressing mechanism (10) via the unloading bush (42) to realize radial flexibility of the compressing mechanism (10). The eccentric crank pin (32) comprises an eccentric crank pin matching part which is in contact with the unloading bush (42) and relatively displaces. The unloading bush (42) comprises an unloading bush matching part which is in contact with the eccentric crank pin (32) and relatively displaces. A wear resisting layer (50) is arranged on at least one part of at least one of the eccentric crank pin matching part and the unloading bush matching part. An unloading bush provided with a wear resisting layer for a scroll compressor and a driving shaft with an eccentric crank pin provided with the wear resisting layer. Because of the arrangement of the wear resisting layer, the service life of the scroll compressor is prolonged.
