Information

The LossyPlanetary gear box is derived from the IdealPlanetary gear box from the standard Modelica Library. It is made up 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 flanges. It is not possible to connect to the planet wheel. Inertia is considered by attaching an inertia block to the planetary gear.

The kinematic equations involving all three gears can be described as follows:

  N_sun/N_ring = (w_planet - w_ring)/(w_sun - w_planet)

  (1+ratio)*w_planet = w_sun + ratio*w_ring

  N_sun + 2*N_planet = N_ring
