Robot 0° Helical Gear – High Precision Transmission Component

The Robot 0° Helical Gear is a high-precision mechanical component designed for robotic systems, automation equipment, and industrial machinery. Unlike traditional helical gears with angled teeth, this gear is manufactured with a 0° helix angle, ensuring straight-line engagement between gear teeth. This design delivers high transmission efficiency, reduced axial thrust, and stable performance, making it ideal for precision-driven robotic applications.

Robot 0° Helical Gear Key Features

• 0° Helix Angle Design: Functions as a spur gear with no axial load, ensuring stable operation in robotic systems.

• High Precision Machining: Manufactured with CNC grinding and advanced heat treatment for superior accuracy and durability.

• Material Strength: Typically made from alloy steel, carburized steel, or stainless steel, providing excellent wear resistance and long service life.

• Surface Treatment: Polished and hardened surfaces minimize friction and enhance efficiency.

• Mounting Holes: Multiple inner bolt holes allow easy assembly and secure installation in robotic gearboxes.
