Steel Double Helical Gear for High Pressure Pump Transmission

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

• Good dimensional stability in high temperature environment, using heat-resistant alloy materials and thermal deformation compensation design;
• Excellent corrosion resistance, the surface can be coated with anti-corrosion coating or corrosion-resistant materials;
• Good sealing in high-pressure environments, the tooth layout can be matched with the sealing structure to prevent media leakage.

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.
