Bevel Gears, also known as Spiral Bevel Gears, have a different design compared to bevel gears, although they seem similar to Bevel Gears in terms of working principle. Although the bevel gears look the same as the bevel gears in terms of operation, unlike the bevel gear, since they can contact more than one tooth at the same time, the gear strength has a higher and less noise level compared to the bevel gear. The bevel gear (Spiral Helical Gear) takes this advantage from its helical conical structure. Spiral Helical/Bevel Gear mechanisms can be used at higher speeds. Spiral bevel gears have the ability to operate at speeds up to 25 m/s for medium diameter circumferential speed.
