摘要： A flexible shaft drive transmission for transmitting rotational power between a drive motor and a gear train of a power operated tool. The flexible shaft drive transmission includes an elongated drive shaft assembly including a rotatable drive transmitting shaft assembly extending through an outer casing. The shaft drive transmission includes a motor end coupling affixed to one end the outer casing and adapted to be releasably connected to a mating coupling of the drive motor. The motor end coupling includes a coupling body having an outer surface tapered region tapering from a larger diameter to a smaller diameter at a distal end of the tapered region to facilitate insertion and proper alignment with the drive motor coupling. The drive transmitting shaft assembly includes a driven fitting having a plurality of drive faces surrounding an axially extending locating member for engagement with a mating drive fitting of the drive motor.
