... is caused by the teeth going in and out of mesh one at a time. However, if first gear (the small helical gear on the left side of Fig. 1 ) is engaged, the transmission is much quieter because multiple teeth are always in contact. Although the helical gears can transmit more power more smoothly...

The torque varies inversely with the speed, and, assuming a constant power transmission of 250 kW (330 hp), the maximum and minimum transmitted torque is 2592 and 2130 N-m (1912 and 1571 ft-lbf), respectively...

Helical gears on crossed shafts make tooth contact only at a point. As the teeth pass through mesh, this point of contact advances from below...
