Title:
AUTOMATIC BALANCING DEVICE
Document Type and Number:
Japanese Patent JP2004336827
Kind Code:
A
Abstract:
To realize very smooth and silent rotational driving with a simple configuration.
A rotation assisting member 20e which regulates or assists free movement of a balancing sphere 20d inside a hollow storage case 20c is a polyhedron comprising a plurality of planner sphere action surfaces 20f. The plurality of planner sphere action surfaces 20f are arranged to slide on the balancing sphere 20d at the start of rotation. In the region of slow rotation including startup, the balancing balls 20d are smoothly moved by a relaxed acting force, to prevent abrupt collision of the balancing spheres 20d, for silent rotation.
