Method for manufacturing slider and compressor with the slider

Abstract

A method of manufacturing a sliding part includes the steps of forming a green member by injection molding integrally and unmixedly two powdery metallic materials of different compositions, sintering the green member and subjecting the green member to at least one heat treatment.

Description

technical field [0001] The invention relates to a method of manufacturing a slide and a compressor provided with said slide. Background technique [0002] Figure 8 is an exploded perspective view of a known shaft assembly for a compressor. A known shaft assembly includes a slider 110, a shaft 120, and carbon-based bearings 130 and 140, shown respectively in Figures 9 to 12 . exist Figure 8 and 9 In , the slider 110 is shown enlarged on a larger scale than the remaining components 120 , 130 and 140 . Such as Figure 9 As shown, the slider 110 is formed with a through hole 111 having a flat surface 12 . Such as Figure 10 As shown, the shaft 120 includes an eccentric shaft portion 121 provided at one end thereof, a flange 123 provided at a middle portion thereof, and a stepped shaft portion 124 provided at the other end thereof. Bearing 130 includes a hub 131 having a bore 132, such as Figure 11 shown, while the bearing 140 has a hole 141, as Figure 12 shown. Th...

[0004] However, in the known shaft assembly of the above structure, since the flat surface 122 of the eccentric shaft portion 121 of the shaft 120 engaged with each other and the flat surface 112 of the slider 110 are made of the same material, and both are subjected to the same process, thus having the same surface properties, with the result that the two may get stuck between

If lubricating oil is supplied to the flat surface 122 of the shaft 120 and the flat surface 112 of the slider 110, in order to prevent such an accident, it is necessary to additionally provide a lubricating mechanism, which makes the known shaft assembly structurally complicated, and the result is very Difficult to manufacture known shaft assemblies at low cost

Meanwhile, if one of the flat surface 122 of the shaft 120 and the flat surface 112 of the slider 110 is coated by a method such as physical vapor deposition (PVD), so that the flat surface 122 of the shaft 120 and the flat surface 112 of the slider 110 If the surface properties of one of the flat surfaces 122 of the shaft 120 and the flat surface 112 of the slider 110 are different from the surface properties of the other of the flat surfaces 112 of the shaft 120, the cost of coating increases and as a result it is also difficult to manufacture the known shaft assembly at low cost.
