1) Description of Double Helical Gear
From the perspective of standardization and versatility, double helical gear is a gear assembly with a modular design concept,
which can replace the gear module according to different transmission parameters (such as transmission ratio, power) to
achieve rapid adaptation to a variety of equipment.
2) Feature of Double Helical Gear
3) Working Principle
The basic parameters such as shaft diameter and hub size of the modular double helical gear are standardized and compatible
with the installation interfaces of different equipment; when it is necessary to adjust the transmission parameters,
you only need to replace the modules of the gear teeth to keep the shaft and other connecting parts unchanged,
and ensure compatibility between the new module and the paired gears through standardized meshing parameters.
4) Application of Double Helical Gear
Flexible transmission systems for automated production lines, multi-functional gearboxes for construction machinery,
standardized transmission units for general machinery, and other equipment that require frequent adjustment or mass production.
