Lightweight Spur Gear
Lightweight Spur Gear: Straight-tooth design with lightening holes and a keyed bore, reducing rotating mass while providing reliable and efficient power transmission.
Brief introduction
Lightweight Spur Gear with Lightening Holes & Keyway
Our Lightweight Spur Gears combine a precision straight-tooth profile with strategically positioned lightening holes and a keyed bore. The lightweight construction helps reduce unnecessary rotating mass while maintaining a practical and reliable gear structure.
The keyway bore provides a secure connection between the gear and shaft, while the straight teeth ensure consistent engagement with the mating gear.
Key Features
Straight tooth profile for reliable power transmission
Lightening holes reduce overall component weight
Reduced rotating mass and rotational inertia for lightweight applications
Keyway bore provides secure shaft-to-gear connection
Compact and efficient gear design
Consistent tooth engagement and stable operation
Suitable for OEM and customized mechanical transmission systems
Applications
Lightweight spur gears are suitable for automation equipment, compact machinery, actuators, gearboxes, robotics, material handling equipment and other mechanical transmission systems where reduced component weight and reliable power transmission are important.
