flexible shaft drive transmission and connecting frame for a flexible shaft drive transmission and a drive motor

摘要

A flexible shaft drive transmission (700) to be coupled between a coupling (915) of a drive motor (901) and a gear train (604) of a power operated tool (100). The flexible shaft drive transmission (700) comprises: a) an elongated drive shaft assembly (800) including a rotatable drive transmitting shaft (802) extending along a longitudinal axis (LASDT), a first driven fitting (814) at a first end (810) of the drive transmitting shaft (802) and a second drive fitting (884) at a second end (880) of the drive transmitting shaft (802), the first driven fitting (814) and the second drive fitting (884) arranged to rotate with the drive transmitting shaft (802); b) an outer casing (704) including first and second ends (710,780) and defining a throughbore (706), the outer casing (704) receiving the drive transmitting shaft (802) within the throughbore (706) and supporting the drive transmitting shaft (802) for rotation within the outer casing (704); and c) the first driven fitting (814) including a plurality of drive engagement faces (832) disposed about an axially extending locating member (822).
