Easy method for manufacturing swash plate and variable capacity compressor adopting the swash plate

摘要

An easy method for manufacturing a swash plate and a variable capacity swash plate type compressor adopting the swash plate are provided. The method for manufacturing a swash plate or a hub having a boss formed by a through hole includes: (a) holding a swash plate or a hub in which a through hole is to be formed at a maximum inclination angle with respect to an horizontal axis; (b) calculating a diameter DH of the through hole using the relation DS<DH<=(DS/cos alpha)+1.0 mm, where DS is the diameter in millimeters of a drive shaft to be mounted passing through the through hole, and a is the maximum inclination angle of the swash plate; and (c) forming the through hole to have the diameter calculated in step (b) through a single process on the swash plate or the hub in a maximum inclination angle position, resulting in the boss of the swash plate or the hub, the single process being carried out in a direction parallel to the horizontal axis.
