THREE-DIMENSIONAL CAM MECHANISM

摘要

The present invention is configured such that a three-dimensional cam guide surface is formed in a three-dimensional cam, and the cam guide surface is caused to guide a cam follower formed at a predetermined angle at one end of a follower side link, so that the rotational movement of the three-dimensional cam is translated into the swinging movement at the other end of the follower side link. As a result, the cam guide surface shape can be selected freely to drastically improve the degree of freedom for selecting the target locus on the follower side, and smooth operations of the three-dimensional cam can be obtained not only by the selection of the shape of a supporting member but also by the free design of the cam guide surface shape, without being neither limited to the power transmission between the orthogonal axes nor followed by the backlash.
