Double Helical Gear OEM Model Key Specifications / Features

1. Product Features
DE industry is a well known leading manufacturer and supplier of double helical gears in worldwide, Double helical gears are also known as herringbone gears. This is a advance version of helical gears its used to defeat the problem of axial thrust of helical gears. These gears are having two sections of teeth, right hand and the other left hand.
• Better in strength .
• High torque.
• Smooth motion at very high rotational velocities.
• No Side ways force and less wear and tear.
2. Manufacturing Capacity/Size
Gears mate via teeth with very specific geometry. Pitch is a measure of tooth spacing and is expressed in several ways.
Pressure angle is the angle of tooth drive action, or the angle between the line of force between meshing teeth and the tangent to the pitch circle at the point of mesh. Typical pressure angles are 14.5° or 20°.
3. Application Analysis
Double helical gears are used for self alignment and they can allow good torque. We offer the same advantages and very good quality similar to single helical gears type. Helical gears are used in marine gear boxes, national defense, rolling mills, steel plants, sugar mills, mines and other industries.
4. Materials
ASTM 4140, ASTM 1045, ASTM 4340.
Chinese Standard: 42CrMo, 45#, 40CrNiMo
We also manufacture custom gears according to specific material requirement.
5. Heat Treatment
Normalizing, Modified treatment, Nit riding, Solt bath nitride, Nickel plating, Quenching.
