Compact Spur Gear

This compact spur gear is a robust, precision-engineered component designed for efficient power transmission in space-constrained mechanical systems.

Construction & Materials

Manufactured from high-strength alloy steel, this gear undergoes a specialized heat-treatment process of quenching and tempering, creating a hardened surface (HRC 45–50) for exceptional wear resistance, paired with a tough, ductile core that can withstand impact loads and shock forces. The entire component is finished with a durable black oxide coating, which provides enhanced corrosion protection, reduces friction during meshing, and helps retain lubricant to extend service life in harsh operating environments, including dusty, damp, or high-temperature conditions.

Design Features

Precision Machined Teeth: The gear teeth are cut using CNC hobbing to achieve an accurate involute profile, ensuring smooth, low-backlash meshing with mating gears. This precision minimizes noise and vibration, even at moderate rotational speeds, while maintaining consistent torque transfer.

Compact, Low-Profile Design: The gear’s short axial length and optimized tooth geometry make it ideal for installations with limited space, such as compact gearboxes, small industrial machinery, and light-duty drivetrains. The central precision-machined bore ensures a concentric, slip-free fit onto drive shafts, maintaining alignment and reducing premature wear.

Optimized 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 design ensures long-term durability and reliable performance in continuous-duty applications.

Performance & Applications

This compact spur gear excels in applications requiring efficient, space-saving power transmission, such as:

Small industrial gearboxes for packaging equipment and conveyors

Agricultural implements and hobbyist mechanical projects

Material handling systems and office automation equipment

Robotics and automated production lines

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