1) Description of Spiral Bevel Gears
Spiral bevel gears are bevel gears whose axes intersect, often at a 90-degree angle. The teeth are cut
with a slight curve along their length and an involute profile.
Spiral bevel gears are often used to transmit power through a right-angle. They are well suited for heavy-duty
applications and can be designed for high-speed operations. Relative to some of the alternative bevel solutions,
hey can reduce the cost of ownership by providing longer-lasting performance and minimal need for repairs
or replacements
