1) Description of Helical Gear
A helical gear is a transmission gear whose key dimensions, such as module, number of teeth, and helix angle,
are determined through parametric design according to operating conditions (such as load, rotational speed, and gear ratio).
2) Feature of Helical Gear
a) High design flexibility, allowing for adaptation to different working conditions by adjusting parameters such as the helix angle and tooth width.
b) The profile shifting modification technology can be applied to optimize the tooth surface contact strength and bending strength.
c) Compared with spur gears, it can achieve a larger gear ratio under the same center distance, simplifying the structural design.
3) Working Principle of Helical Gear
By accurately calculating the tooth surface contact stress and tooth root bending stress, and combining with
the allowable values of materials, it ensures the safe operation of the gear under rated operating conditions and avoids fatigue failure.
4) Application of Helical Gear
It is used in application fields with high requirements for customized design, such as robotic joint transmission mechanisms,
medical device transmission systems, and electric vehicle reducers.
