The motion of planetary gear systems is expressed clearly in the Plantetary Train Equation: -S/R = (ωr-ωa)/ (ωs-ωa). Once this is known, the speeds of the carrier arm, sun and/or ring can be calculated. Multiple series of planetary gear systems can be used to get multiple speeds and directions. Planetary gear systems are used everywhere.

The Planetary Gear block implements an ideal planetary gear coupling consisting of a rigidly coupled sun, ring, and carrier gears. The block calculates the dynamic response to the sun, carrier, and ring input torques. In fuel economy and powertrain studies, you can use the Planetary Gear block as a power-split device by coupling it to common

Epicyclic gearing or planetary gearing is a gear system consisting of one or more outer, or planet, gears or pinions, revolving about a central sun gear or sun wheel. Typically, the planet gears are mounted on a movable arm or carrier, which itself may rotate relative to the sun gear.

As shown in Fig. 1, the planetary gear train presented in this study was modelled using ANSYS R15.0, while Finite Element Method (FEM) was employed in the simulation of the gear models. The planetary gear train is made up of two or more gears assembled such that the center of one gear rotates around the center of the others.

Planetary Gear Train Analysis. The planetary gear train is an important, but complex mechanism. When it comes to analyzing rotation directions and gear speeds, intuition is not enough. We'll look at the superposition method to determine speeds and rotation directions. For a planetary (a.k.a. epicyclic) gear train there are three possible inputs

First off, assembling the sun gear is simple; take the threaded axle and screw it into the hole opposite of the other axle of the sun gear. Next, prepare the planetary gears by inserting each onto the three axles of the male bracket. It doesn't matter which one goes where on it, as each of these are the same. Add Tip.

The Double-Pinion Planetary Gear block represents a planetary gear train with two meshed planet gear sets between the sun gear and the ring gear. A single carrier holds the two planet gear sets at different radii from the sun gear centerline, while allowing the individual gears to rotate with respect to each other.
