ABSTRACT:
An electrical generator has a rapidly replaceable bearing assembly and motor mounting and method of manufacturing the same. The generator is of the type having a housing holding an armature secured to a generator shaft rotating within the interior of the housing. The housing has a passage through the housing end bell. A bearing assembly rotatably supporting the generator shaft is mounted in the passage. An annular shoulder is formed in the interior wall of the generator housing concentric to the passage. The annular shoulder comprises a first side essentially parallel to the longitudinal axis of the generator shaft and a second side extending between the first side and the passage. An outer groove is formed in the first side of the annular should for mounting a removable outer retaining ring and an inner groove is similarly formed in an outside wall of the bearing assembly that is adjacent to the wall of the passage for mounting a removable inner retaining ring to secure the bearing assembly against the undesired movement outwardly of the housing. The inner and outer rings coact to lock the bearing assembly in the passage. A through-stud extending through an axial bore formed in the generator shaft is attached to a tap slug adaptor having an axial bore with splines for receiving the motor shaft. The tap slug adapter demountably secures the motor shaft in an essentially aligned relationship with the generator shaft.
