ABSTRACT:
A rotary-to-linear actuator includes two thrust plates. One of the thrust plates has three roller assemblies secured thereto. The roller assemblies are equiangularly spaced and disposed at separate radii. The other thrust plate has three ramps formed thereon in juxtaposed relation to respective ones of the roller assemblies. One of the thrust plates is rotatable relative to the other whereby the action between the roller assemblies and the ramps causes the rotary action of the one thrust plate to induce linear movement in the other thrust plate. The radially spaced roller assemblies and ramps permit substantially 360 degrees of rotation at the rotatable plate during linear movement of the other plate.
