- SWASH PLATE WITH COBALT-TIN ALLOY COATING

摘要

The inclined plate compressor 10 includes a cylinder block (12, 14) having a cylinder bore disposed parallel to the axis of the cylinder block. A rotary shaft 22 rotatably mounted in the cylinder block to support the aluminum swash plate (20). Inclined plate 20 is fixed to the rotary shaft 22 is provided with two surfaces 26 with the end face (28). Inclined plate (20) has at least 0.2 weight percent cobalt with the balance of the tin coating layer. A piston (16) fitted with a reciprocating within the cylinder bores 18 includes a piston 16 and the swash plate surface 26 of the shoe 24 disposed slidably between. The shoe (24) changes the rotational movement of the swash plate 20 to the linear motion of the piston (16). The coated surface 26 of the swash plate 20 is slidably in contact with the shoe (24). Coating on the swash plate 20 allows the use of a low silicon aluminum alloy, without also requiring a metal coating or a high degree of finishing grinding.
