I am building a machine, and one of it's components is a mechanism that will convert rotational energy to a reciprocating horizontal movement.
I am aware of various mechanisms such as the Scotch Yoke shown below:
Which perform this translation. In fact, I would have used the Scotch yoke since it is mechanically simpler - however, the problem with the Scotch Yoke is that the extent of the lateral motion is constrained to the diameter of the wheel.
What I want is to be able to create a lateral reciprocating movement of extent NxD where N is a positive real number, and D is the diameter of the wheel.
Is there an existing mechanism that generates lateral displacements that are several times larger than the diameter of the rotating circle/wheel?
