Helical bevel gear is a toothed gear in angular design. The input side
is provided with a motor flange or a free input shaft and the output
side are provided with a free shaft end or a hollow shaft. Helical bevel
gears are fitted with flanges of various sizes. Reciprocating tools cuts
them. The advantages of helical bevel gears are high efficiency and low reduction rate. The use of helical bevel gear saves energy and cost. Helical bevel gears are manufactured by an alloyed case hardening steel. The gear material is given an extremely strong, homogeneous structure.
They can replace worm gears in a variety of applications, particularly in modular machinery. They are also used as storage and retrieval unit. They are commonly used in modern differentials.
