Helical Gear

This precision-engineered helical gear is a high-performance transmission component designed for smooth, efficient power transfer in demanding industrial and automotive applications.

Construction & Materials

Manufactured from premium alloy steel, the gear undergoes a specialized heat-treatment process that combines carburizing, quenching, and tempering. This creates a hardened tooth surface (HRC 58–62) for exceptional wear resistance, paired with a tough, ductile core to withstand high impact loads. The finished black oxide coating provides enhanced corrosion protection, reduces friction during meshing, and extends service life in harsh operating conditions, including dusty, damp, or high-temperature environments.

Design Features

Helical Tooth Profile: The angled, helical teeth engage gradually with mating gears, distributing contact stress across a larger surface area compared to spur gears. This design significantly reduces noise and vibration, enabling quieter operation even at high rotational speeds, while also increasing load-carrying capacity.

Precision Machining: The gear teeth are cut using CNC gear hobbing to ensure a precise involute profile, guaranteeing smooth meshing, minimal backlash, and consistent torque transfer. The central precision-machined bore ensures a concentric, slip-free fit onto drive shafts, maintaining alignment and reducing premature wear.

Optimized Geometry: The helix angle and tooth profile are engineered to balance axial thrust and load distribution, minimizing the risk of pitting, scuffing, or tooth failure. This results in a longer service life and reliable performance in continuous-duty applications.

Performance & Applications

This helical gear excels in applications requiring high torque, low noise, and smooth operation, such as:

Industrial gearboxes for conveyors, mixers, and material handling systems

Automotive transmissions and drivetrain components

Heavy-duty construction machinery and agricultural equipment

Precision robotics and automated production lines

Its combination of rugged construction, precision engineering, and corrosion resistance makes it a dependable choice for critical systems where downtime is costly and performance is essential.
