Abstract

See full text

A dynamic balance testing device includes a vibrating unit configured to rotatably hold a predetermined rotating body being a specimen, a first spring configured to elastically support the vibrating unit and restrict displacement of the vibrating unit in a direction parallel to a rotation axis of the predetermined rotating body, and at least three second springs configured to elastically support the vibrating unit and restrict displacement of the vibrating unit in a predetermined direction orthogonal to the rotation axis. The at least three second springs are attached to the vibrating unit on a same predetermined plane, and the vibrating unit holds the predetermined rotating body such that a projection of a center of gravity of the predetermined rotating body onto the predetermined plane is substantially at the same position as a position where the first spring is attached to the vibrating unit.
