Model of the simplified single pinion PGS for example consists of two 0-junction and one 1 junction and one transformer with module reflecting the ratio between the ring and sun gear
teeth counts ([beta]=[z.sub.r]/[z.sub.s]).
The sun gear
of the planetary gear is connected to a small motor while the ring gear connected to a larger driving motor.
Make sure your summer adventure pack is full of sun gear
: sunscreen, sunglasses, SPF clothing, and a baseball cap or a wide-brimmed hat.
Control in such devices is realised by means of a sun gear
, which rotates the hydraulic pump of a closed hydraulic system through a gear train and pumps the liquid in it with a certain angular velocity of the control link.
The small sun gear
of the front PGT is connected to MG1, which can be held stationary by the wet brake clutch B2.
'We wish to remind everyone to bring sun gear
, like umbrellas, sunglasses and hats due to the hot weather.
As is common in the horizontal wind turbines, the ring gear would be connected to the bedplate, and the planet carrier would be connected to the rotor hub, while the sun gear
would be connected to the output shaft, which is connected to the next stage.
The reducer, comprising two-stage planetary gear sets with sun gear
input and carrier output, provides the output power to cutting head.
MG2 is linked to the sun gear
directly, while MG1 is connected to the ring gear and separated from engine by an electronic control clutch.
We observed that the meshing frequency under three- axis driving occurred at two kinds of frequency harmonics, caused by the meshing relationship between ring and planet gear and between planet and sun gear
. Comparing these results, we constructed a method of calculating their frequencies on the basis of instantaneous rotation center theory.
This is much simpler than using a mechanical planetary system where the speed of the sun gear
must be controlled.
Former basic units 1c (planetary carrier) and 1s (sun gear
) are connected to units 2r (inner ring) and 2c (planetary carrier) of differential gear train, respectively.
