MOTOR-DRIVEN DEVICE

PROBLEM TO BE SOLVED: To provide a motor-driven device which is driven by a motor and is displaced by a worm gear and a worm wheel and thereby outputs power, wherein the gear will not lock, even if the worm wheel is stopped by a rotation arresting means. SOLUTION: Gear lock occurs, when the rotation...

Zusammenfassung:PROBLEM TO BE SOLVED: To provide a motor-driven device which is driven by a motor and is displaced by a worm gear and a worm wheel and thereby outputs power, wherein the gear will not lock, even if the worm wheel is stopped by a rotation arresting means. SOLUTION: Gear lock occurs, when the rotation of a worm wheel 3 is arrested and a worm gear 4, and the worm wheel 3 are abutted hard against each other by inertia force. The motor-driven device 1 is so constituted that the occurrence of gear lock is avoided, by relieving the impulsive force through a relieving mechanism which uses bearings 13 and 16 and coned disc springs 12 and 15.
