ROTATION DRIVING DEVICE FOR ENGINE TEST

摘要

PROBLEM TO BE SOLVED: To provide a rotation driving device for an engine test capable of rotationally driving a crankshaft by means of an external driving means with low rattling while allowing smooth connection between the crankshaft of the engine and a driving shaft of an electric motor M. SOLUTION: Rugged meshing engagement parts meshing with each other along an axial direction are individually formed along the circumference in an operated part 6A connected to the crankshaft of the engine 2A and a driving operation part 8 connected to the driving shaft 7 of the external driving means 4. A recess part in the meshing engagement part is formed into a taper narrowing its circumferential opening width gradually toward the inner depth side along the axial direction, while a projection part is formed into a taper narrowing its circumferential width gradually toward the tip side along the shaft center direction. A holding means holding a relative position while pulling an operated member and a driving operation member together is provided in this rotation driving device. COPYRIGHT: (C)2004,JPO
