ABSTRACT:
This patent discloses a method of manufacturing rotors particularly adapted for use in hermetically sealed motor-compressor units of the type to be utilized for refrigeration applications. Previously known standard manufacturing steps are followed in producing a rotor having counterweights at one end thereof secured to the rotor by any suitable fastening means. Practice of the present invention results in rotors that include a shroud overlying the counterweights. In the manufacture of the shroud itself, I locate a centrally disposed region and define such region by piercing the shroud material along a major portion of its perimeter, but retain at least two tabs or ears which interconnect the centrally disposed portion of the shroud with the remainder of the shroud. The resulting shroud preferably has a centrally disposed portion which then may be separated from the remainder of the shroud by fracturing the interconnecting tabs in order to expose the rotor shaft.
Thereafter, the shaft may be pressed out of the rotor, and the central portion of the shroud retained. Subsequently, the central portion of the shroud is relocated on the remainder of the shroud, pressed into position, and refastened by any suitable means, such as, but not limited to, spot welds, silver solder, brazing, etc. The rotor having a reassembled shroud then is usable in a reassembled compressor.
