Helical Gear OEM Model

1. Helical gears used the helix angle of one having the negative of the helix angle of the other; such a pair might also be referred to as having a right-handed helix and a left-handed helix of equal angles. When two equal but opposite angles are added the angle between shafts is zero, that is, the shafts are parallel.
  • Helical Gears are smooth and quit operation
  • High Speed and Durable
  • Higher loading capacity

2. Manufacturing Capacity/Size

3. Functional Analysis
DE industry producing best quality helical gears, we are the leading supplier of helical gears for all major industries like steel, OEM equipment manufacturers, rubber industry, defense, marine, mining and automotive industries.
Helical gears are used for high speed, high power mechanical systems. They make less noise. Helical gears can handle more load as gear tooth is effectively large. Helical gears work perpendicularly to each other when the teeth of the helical gears are designed correctly. The machines that use helical gears are expensive and require high maintenance and service charge.

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.
