The designs: Design A | is inspired by the Industrial Revolution invention of the sun and planet gear
system invented by William Murdoch for Boulton & Watt.
However, each planet gear
is actually a compound design which meshes with two sun pinion shafts: one input shaft and one output shaft.
The root of the failure was a magnetic particle found on the chip detector of the part of the main rotor gearbox known as the second stage planet gear
Figure 3 shows one of the examined Response Surfaces for the safety factor, in respect to the planet gear
diameter and the output torque.

Thus, they differ from an ordinary parallel shaft gear trains by having a moving axis or axes: sun pinion gear, planet gear
, planet carrier, internal toothed ring gear--annulus, Fig.
In response Watt and William Murdock invented the sun and planet gear
system, whereby one or more outer gears, or planet gears
, rotate around a central or sun gear.
The entire mechanism is considered to be locked together and the whole device is rotated one turn in a clockwise position around that axis about which the planet gear
pin is carried.
Due to normal manufacturing tolerances however, a sun gear which is securely fixed on a shaft will intermittently have more load on one planet gear
than on another gear.

The planet gear
movement is transmitted to the output shaft.
