Three sets of gears with the same diameter of cylindrical gear, bevel gears and worm gear tooth which group can obtain larger output torque
Low speed transmission, if the load is not large, usually straight gear. Lower cost
The helical gear tooth forms a certain angle with the gear shaft.The engagement ratio of helical gears is better when meshing, which is more suitable for occasions with large load and low rotating speed.
Bevel gears are generally referred to as bevel gears.The difference between straight and helical gears is the shape of teeth. The spur gear is parallel to the gear shaft,
