Spiral gear milling machine
Bevel gears is one type gear used for transmitting mechanical power and motion, according to the teeth profile, it
can be divided into straight bevel gear, spiral bevel gear, hypoid gear,these gears are
widely used for transmitting
power and motion between nonparallel axes and are
designed to transmit motion between intersecting axes,
generally at right
angles. this type of gears
are suitable when the direction of a shaft's rotation needs to be changed.
