Ideal Planetary

Ideal planetary gear box Description The Ideal Planetary component is an ideal planetary gear without inertia, elasticity, damping or backlash. It consists of an inner sun wheel, an outer ring wheel, and a planet wheel located between sun and ring wheel. The bearing of the planet wheel shaft is fixed in the planet carrier. The component can be connected to other elements at the sun, ring and/or carrier flanges. There is no connection to the planet wheel.
 Equations $\left(1+r\right){\mathrm{\phi }}_{\mathrm{carrier}}=r{\mathrm{\phi }}_{\mathrm{ring}}+{\mathrm{\phi }}_{\mathrm{sun}}$ ${\mathrm{\tau }}_{\mathrm{ring}}=r{\mathrm{\tau }}_{\mathrm{sun}}$ ${\mathrm{\tau }}_{\mathrm{carrier}}+{\mathrm{\tau }}_{\mathrm{sun}}+{\mathrm{\tau }}_{\mathrm{ring}}=0$
