IMPROVED TEETH'S GEARING STRUCTURE WITH STRAIN WAVE GEARING APPARAUTERS

摘要

The present invention relates to a distortional wave gear apparatus having a cam plate provided on a wave generator generating a wave by receiving a rotational force from a drive motor as a drive source, wherein a second curved portion having the radius of curvature larger than that of a first curved portion and smaller than that of a third curved portion between the first curved portion related to a long shaft and the third curved portion related to a short shaft in the cam plate. According to the present invention, the curved portion having a middle size of the radius of curvature is formed between the first curved portion having small radius of curvature and the third curved portion having the largest radius of curvature for a cam curved line therein to protrude compared with the past. Therefore, the second curved portion is related to an extended line of the first curved portion which is coupling portion to substantially extend the coupling portion.
