mounted at almost any shaft angle. Straight bevel gears are the least costly type of bevel gears, but they are also limited in application for similar reasons as the spur gear (Hamrock et al. 2005, pg. 678-680). The next type of gear, and the most advanced gear discussed in this report, is the spiral bevel gear.
