Mechanisms generating rocker curves have a great use in the machine building industry. In the specialty literature a lot of papers have been published regarding the analysis and synthesis of mechanisms for rocker curves. In this paper the R-RRR-RPP-RPP mechanism is studied, a three-diade mechanism that generates special rocker curves. There are obtained many rocker curves, most of which are unknown in the mechanisms. A generator point belongs to RPP diade that slides on a rocker and another is on another RPP diade sliding on a rotating moving element. The rocker curves generated by the point that slides on a rocker are more complicated and more interesting than those at which the generator point slides on a rotating motion element. The angles between the welded slides have changed and the same curve shapes have been obtained, with some modifications and different positions on the axis system. In this way a wide range of special rocker curves generated by the mechanisms were obtained. The results obtained from the study can be used in the design of new mechanisms generating of rocker curves.
