Abstract:
A torque tool assembly comprising:a main housing being of a generally cylindrical elongated construction, a drive motor subassembly including a drive motor secured in a motor housing, a gear subassembly including a gear train structure supported in a gear train housing, drive means adapted to operatively engage said drive motor with said gear train structure whereby said drive motor can drive said gear train structure, said drive motor subassembly adapted to be mounted within said main housing while being freely moved from a forward end of said main housing, locating means operatively connected to said motor housing and said main housing for locating said drive motor subassembly at a pre-selected position within said main housing while blocking further movement of said drive motor subassembly into said main housing, said gear subassembly adapted to be mounted to said main housing with said gear train housing having a housing portion extending at least partially into said main housing with said drive means being operatively engaged, locking means operative with said main housing and said gear train housing and adapted to mechanically and immovably lock said gear train housing and thus said gear subassembly at a preselected position in said main housing, said preselected position of said gear subassembly placing said drive means into operative engagement between said drive motor and said gear train structure while locating said gear train housing a preselected distance from said motor housing to define a gap, resilient means located in said gap and in operative engagement with said motor housing and said gear train housing to bias said locating means to resiliently locate said drive motor subassembly at said preselected position within said main housing with said resilient bias being reacted through said gear train housing against said locking means, said gap maintaining the desired engagement and alignment of said drive means relative to said drive motor and said gear train structure.
