Bevel Gearbox

Spiral bevel gears use gear teeth that are angled and spiraled. With this design, as the gears rotate, the entire face width of the mating teeth don't contact simultaneously and more teeth are in contact at one time. This results in a quite operating noise and increased torque capacity. The quiet operation is particularly beneficial in environments such as theaters or airports. The rolling action of bevel gears is extremely efficient (98.5%) compared to the sliding action of worm gears. NORD bevel gears operate with a microscopic oil film between the gearing which results in no metal to metal contact which improves efficiency and results in essentially wear free gearing.
