ABSTRACT:
An improved supercharger (10) of the Roots-type. The supercharger includes a three-piece housing assembly (14, 16, 18) defining generally cylindrical chambers containing two rotors (20, 22) having meshed lobes (20c, 22c) of modified involute profile which pump air from an unshown inlet to an outlet (56). The rotors are fixed to stepped diameter shafts (24, 26) pressed into centrally located through bores in the rotors. Straight splines (24e, 26e) on the shafts form mating splines in the rotor bores to prevent rotation of the shafts in the bores. Bearing assembly (28, 30) disposed at adjacent ends (20a, 22a) of the rotors support one end of the rotors in the housing and fix the axial position of that end of rotors relative to the housing. Bearing assemblies (32, 34) at the outer adjacent ends (20b, 22b) of the rotors support the other end of the rotors in the housing. The bearing assemblies (32, 34) include inner races pressed on shaft bosses (24b, 26b) and outer races slidably disposed in wear-resistant sleeves pressed into bores in housing end section 18. The outer races of bearing assemblies (32, 34) are biased away from bearing assemblies (29, 30) to remove radial and axial bearing play in all of the bearing assemblies.
