Structure of mechanism |
Function |
The mechanism contains a slider crank kinematic chain connected in parallel with a four bar linkage. The kinematic chain RRT´s joints are connected with the coupler and rocker of the four bar linkage. By means of changing the geometrical lengths of the mechanism´s links the coupler, point M describes a range of coupler curves. |
