Helical Gearbox

Second, the planet gear bearings need to play an active part in torque transfer. Planetary systems split the torque input from sunlight gear amongst the planet gears, which transfer torque to a planet carrier linked to the gearbox output. The bearings that support the planets on the carrier have to bear the full brunt of that torque transfer.

Or, in extreme cases, they could select angular contact or tapered roller bearings, both which are made to withstand axial loads.
In planetary Helical Gearbox gearboxes, however, it’s much more difficult to create around these axial forces for just two related reasons. Initial, there is typically hardly any 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 support the additional forces.

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

Helical Gears Place Greater Demand on Bearings
