非グラスホフ平面4節リンク機構のカップラカーブの分類と駆動法

抄録

The driving link of nongrashof planar four-link mechanisms, that none of two adjacent links can make a complete rotation, oscillates in such a manner that coupler and driven links take different forms of two link chain in going and returning respectively. In this paper, the characteristic of relationships between the input and output angles is made clear. The coupler curve is classified according to the number of rotation and numbers of nodes, maximum curvature points, inflection points. Moreover, in order to perform one cycle motion of the nongrashof mechanism, the crank rocker mechanism whose oscillating range coincides with that of its driving link is designed. Pin gear trains to drive supplementally the driven link are presented so that the nongrashof mechanism may pass through limit positions.
