Spur Gear

This spur gear with a plain bore is a fundamental, rugged power transmission component designed for efficient torque transfer between parallel shafts in mechanical systems. Its simple, straight-tooth design ensures reliable performance and easy integration into a wide range of industrial, agricultural, and automotive applications.

Construction & Materials

Manufactured from high-strength carbon alloy steel, the gear undergoes a specialized heat-treatment process of quenching and tempering. This creates a hardened tooth surface (HRC 45–50) for exceptional wear resistance, paired with a tough, ductile core that can withstand impact loads and torsional stress. 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. The precision-machined plain bore ensures a secure, slip-free fit onto drive shafts.

Design Features

Straight Tooth Profile: The parallel, straight-cut teeth engage with a mating spur gear to transfer torque efficiently between parallel shafts. This design ensures predictable performance and is easy to manufacture, making it a cost-effective solution for many applications.

Precision Machined Teeth: The teeth are cut to exact industry standards using CNC hobbing, ensuring a precise involute profile that meshes smoothly with mating gears. This minimizes noise, vibration, and wear, while maintaining consistent torque transfer.

Plain Bore Design: The smooth, precision-machined bore allows for a direct press fit onto drive shafts, eliminating the need for additional keyways in light to medium-duty applications and simplifying installation.

Performance & Applications

This spur gear excels in applications requiring reliable, cost-effective power transmission between parallel shafts, such as:

Industrial gearboxes and conveyor systems

Agricultural machinery including tractor transmissions and grain augers

Automotive drivetrains and auxiliary systems
