1) Description of Double Helical Gear
From the perspective of extreme working conditions adaptability in specific industries, double helical gear is a special gear
that can adapt to harsh environments such as high temperature, high pressure, and corrosiveness,
and meets the special needs of the industry through structural optimization and material treatment.
2) Feature of Double Helical Gear
3) Working Principle
In high temperature working conditions, the material and structure design of double helical gears reduce the impact of thermal expansion on the meshing gap
and maintain stable transmission. In corrosive environments, anti-corrosion coatings or corrosion-resistant materials isolate the corrosive medium from contact
with the tooth surface to avoid tooth surface rust. In high-pressure environments, the mating gap between the gear teeth and the housing is precisely calculated
to prevent high-pressure media from penetrating into the gearbox.
4) Application of Double Helical Gear
Special environmental equipment such as high-pressure pump transmission system in the petrochemical field, drive mechanism of nuclear industry equipment,
and high-temperature rolling mill transmission device in the metallurgical industry.
