Abstract

PURPOSE: To shape an external form simply with a high precision and make it possible to secure weight to improve economization and productivity, by forming the external shell body of the flywheel by a thin material and by burying the weight core material into this external shell body.
CONSTITUTION: Flywheel 1 consists of external shell body 2 and weight core material 3, and rotation axis 4 is protruded in the center. This external shell body 2 is draw-formed by providing frame part 5 and concentric circle-shaped concave 6 in the soft steel plate of 1mm or less by a press molding machine. In case that the thin material is subjected to press molding in this manner, the perfect round degree is high, and the circumference edge corners are shaped with a high precision. Core material 3 is fitted to the inside circumference of external shell body 2, and they are fitted into one body by press, so that a prescribed external form precision can be obtained and weight can be secured by weight core material.
