Helical Gearbox

Second, the planet gear bearings have to play an active role in torque transfer. Planetary systems split the torque insight from the sun gear amongst the earth gears, which in turn transfer torque to a world carrier connected to the gearbox output. The bearings that support the planets on the carrier have to bear the full brunt of this torque transfer.

Or, in extreme cases, they may select angular contact or tapered roller bearings, both which are designed to withstand axial loads.
In planetary gearboxes, however, it’s much more difficult to design around these axial forces for two related reasons. First, there is typically very little area in a planetary gearbox to include the kind of bulky bearings that may tolerate high axial forces.

The presence of axial forces makes things completely different for the bearings that support helical gears. But it is critical to make a distinction between fixed-axis and planetary gearboxes. In fixed-axis gearboxes, the excess axial forces amount to little more than a hassle. Gearbox designers will most likely upsize the bearings to accommodate the additional forces.

Since they don’t need to withstand any axial forces, spur gear bearings play just a supporting function in the functioning of the gearbox. The bearings should just support the rotating gear shafts, however they do not really play an active role in torque transfer.
