Product Description
Description of Double Helical Gear: From the perspective of the relationship between power transfer efficiency and structural size, double helical gear is a form of gear that can transmit more power in a unit volume, and the power density is improved by optimizing the tooth layout and force distribution.
Feature of Double Helical Gear:
- The transmission power is greater under the same size
- Symmetrical distribution of teeth makes contact stress more uniform with high material utilization rate
- Compact structure enables high-power transmission in limited space
- Strong overload resistance with load shared by multiple sets of wheel teeth
Working Principle: When subjected to high power input, the symmetrical teeth engage with multiple tooth surfaces simultaneously, distributing torque to more contact points. This reduces load per unit tooth surface, enabling efficient high-power transmission in smaller structures while preventing excessive wear or breakage.
Applications: Equipment requiring ultra-high power transmission in compact spaces, including ship propulsion system reduction gearboxes and speed boosters for large wind turbines.
