Flat Spur Gear

This flat spur gear is a precision-engineered, cost-effective solution for reliable power transmission in a wide range of mechanical systems.

Construction & Materials

Manufactured from high-quality carbon steel, this gear undergoes a controlled heat-treatment process of quenching and tempering to achieve a balanced hardness of HRC 38–42, delivering excellent wear resistance while maintaining sufficient toughness to withstand shock loads. The surface is finished with a black oxide coating, which provides enhanced corrosion protection, reduces friction during initial meshing, and helps retain lubricant for extended service life in both indoor and outdoor operating environments.

Design Features

Involute Tooth Profile: The gear teeth are precision-cut using CNC hobbing to ensure an accurate involute form, enabling smooth, low-backlash meshing with mating gears. This design ensures consistent torque transfer and minimizes noise and vibration in moderate-speed applications.

Thin, Flat Profile: The slim, flat construction makes this gear ideal for installations with limited axial space, such as compact gearboxes, small machinery, and light-duty conveyor systems. The central precision-machined bore ensures a concentric, slip-free fit onto drive shafts, maintaining alignment and reducing premature wear.

Uniform Tooth Geometry: Each tooth is engineered to distribute contact stress evenly across the tooth face, reducing the risk of pitting, scuffing, or tooth fatigue. This results in a longer service life and reliable performance in continuous-duty applications.

Performance & Applications

This flat spur gear is well-suited for applications requiring efficient, cost-effective power transmission, such as:

Light-duty industrial machinery, including packaging equipment and small conveyors

Agricultural implements and hobbyist mechanical projects

Material handling systems and office automation equipment

Precision instruments and medical devices

Its combination of rugged construction, precision machining, and corrosion resistance makes it a dependable choice for both stationary and mobile equipment where space is limited and performance is essential.
