METHOD OF MANUFACTURING A SWASH PLATE ASSEMBLY

摘要

METHOD OF MANUFACTURING A SWASH PLATE ASSEMBLY : An improved method of manufacturing a swash plate assembly (9) for use in a compressor, fluid motor or similar device in which a plurality of pistons are connected, by means of connecting rods, to a swash plate (10) which drives (or is driven by) the pistons. A plurality of piston assemblies are made by casting the piston around one end of a connecting rod section which is formed with a ball (18) thus providing a ball-socket connection therebetween. Mating spherical ends with through-bores (27) to receive the piston connecting rod section are cast-in-place and captured in sockets within the swash plate. The connecting rod section of the pistons is mated to the through-bores (27) of the mating spherical ends and are positioned in an appropriate fixture to a fixed final relationship. The connecting rod sections are secured to the sidewall (29) of each through-bore (27) by a means such as electron-beam welding to secure the overall length of the final assembly.
