Brief introduction

Helical Gear with Keyway

Our Helical Gears are designed for smooth and reliable power transmission in mechanical drive systems. The angled tooth profile provides gradual tooth engagement, helping to reduce vibration and operating noise compared with conventional spur gears.

The integrated keyway bore provides a secure connection between the gear and shaft, helping to prevent relative rotation during operation.

Key Features

Helical tooth profile for gradual and smooth tooth engagement
Lower operating noise and vibration compared with spur gears
Efficient and stable power transmission
Keyway bore for secure shaft connection
Compact, hubless design for space-efficient applications
Available in various tooth counts, module, bore sizes and helix angles
Suitable for standard and customized mechanical transmission systems

Applications

Helical gears are widely used in industrial machinery, automation equipment, gearboxes, conveyors, material handling systems and other mechanical power transmission applications where smooth and reliable operation is required.
