GF27.50-P-5100-01NN Planetary gear set, function
- TRANSMISSION 722.9
- Simple planetary gear system

Component Identification:

The ring gear (3), sun gear or planet gear carrier (2) elements of a single planetary gear system are alternately driven and braked by the actuating elements of the multidisk clutch and multidisk brake. In the process, the planetary gears (1) can roll on the internal toothing of the ring gear (3) and on the external toothing of the sun gear. This allows for a variety of gear ratios and the reversal of the rotation direction without the need for moving gear wheels or shift collars.

The torque and engine speed are converted according to the lever ratios or the ratio of the number of teeth on the driven gears to that on the drive gears, and is referred to as the gear ratio i. The overall ratio of a number of planetary gear sets connected in series is obtained by multiplying the partial ratios.

If 2 components of a single planetary gear system are rigidly connected to each other, then this is locked and rotates as a closed unit.

Advantages of a single planetary gear system
^ Shifting ability under load
^ Several ratios can be produced
^ Constant meshing of the gears
^ Simple direction reversal
^ High efficiency
^ Coaxial location of input and output
^ Compact design
