Ideal Rotational to Translational Gear

Gearbox transforming rotational into translational motion

 Description The Ideal Rotational to Translational Gear (or Ideal Gear R2T) component transforms 1D-rotation to 1D-translation. It is lossless and has no mass or inertia. The Use Support R and Use Support T boolean parameters enable rotational and translational support flanges. When true (checked) the corresponding support flange must be connected. When false the flange is internally fixed to ground.
 Equations $0=r{\mathrm{\tau }}_{R}+{f}_{T}$ ${\mathrm{\phi }}_{R}-\left(\left\{\begin{array}{cc}{\mathrm{\phi }}_{\mathrm{SR}}& \mathrm{Use Support R}\\ 0& \mathrm{otherwise}\end{array}\right)=r\left({s}_{T}-\left(\left\{\begin{array}{cc}{s}_{\mathrm{ST}}& \mathrm{Use Support T}\\ 0& \mathrm{otherwise}\end{array}\right)\right)$ $\mathbf{if}\mathrm{Use Support R}\mathbf{then}{\mathrm{\tau }}_{\mathrm{SR}}=-{\mathrm{\tau }}_{R}$ $\mathbf{if}\mathrm{Use Support T}\mathbf{then}{f}_{\mathrm{ST}}=-{f}_{T}$
