发明名称 回転塑性加工装置
摘要 Provided is a rotational-plasticity forming device capable of improving plasticity-forming accuracy. This synchronous rotational structure (S) is equipped with a synchronous gear (8), a transmission gear (9), an eccentric coupling (10), and a transmission-gear-position-holding mechanism (K). In the eccentric coupling (10), a drive plate (14) is connected concentrically to the transmission gear (9) so as to be integrally rotatable, and a driven plate (12) is connected concentrically to a roller (4) so as to be integrally rotatable. The eccentric coupling (10) is provided in a manner such that the rotational axis (A2) of the driven plate (12) is parallel to a principal shaft (1). A pressing mechanism (D) is provided so as to move the roller (4) and the driven plate (12) in a manner such that the rotational axis (A2) of the roller (4) travels along an interaxial perpendicular line (α). The transmission-gear-position-holding mechanism (K) is configured so as to hold the transmission gear (9) in a state of engagement with the synchronous gear (8) at a position where the rotational axis (A4) of the transmission gear (9) is biased by a set amount from the interaxial perpendicular line (α) toward a direction perpendicular to the interaxial perpendicular line (α).
