The revolving shaft, which connected with the planet carrier
serving as a revolving member, is rigid.
When the input speed of planet carrier
is given at any time, the characteristic frequency of each component in the planetary gearbox can be calculated by using the expressions of planetary gearbox characteristic frequencies listed in Table 2, which are deduced from the configuration of planetary gearbox.
The coupled power output through planet carrier
and the planet carrier
was linked to the wheels by transmission system.
The gear-train diagram of precessional transmission K-H-V (look to the figure 1 a) consist of four elements: planet carrier
H, satellite wheel g, central wheel b and body.
By connecting the variator input to the sun and the variator output to the annulus, the planet carrier
rotates at the speed difference between the two which can be positive, negative or zero.
To reduce sliding friction between the bearing balls and planet carrier
bolts the rolling or sliding bearings are applied.
The Hercules axles have a 6:1 planetary ratio and incorporate an overhung planet carrier
with four-pinion planetary gear system.
The planet carrier
originally was assembled by press fitting steel pins into steel plates to form a lugged structure for maintaining gear alignment during a hard stop.

The gear case absolute vibrations were measured in horizontal-radial direction with piezo accelerometers stationary attached at planet carrier
fixed location on the gear case point, as shown in Fig.
