Every Helical Gear manufactured at Shreeji Gears reflects our commitment to precision engineering, smooth motion, and long-term reliability. The helical gear shown above is a custom-manufactured component designed for a demanding industrial application where noise reduction, load distribution, and durability are critical.

⚙️ What is a Helical Gear?

A helical gear is a type of cylindrical gear where the teeth are cut at an angle (helix angle) to the gear axis. Unlike spur gears, helical gears engage gradually, resulting in smoother operation, higher load capacity, reduced vibration, and quieter performance.

Helical gears are widely used in gearboxes, automotive transmissions, industrial machinery, compressors, conveyors, and precision motion systems.

🧩 Technical Specifications of This Helical Gear

🔧 From Design to Precision Helical Gear

Manufacturing a high-quality helical gear begins with an accurate drawing that defines module, helix angle, pressure angle, tooth profile, bore tolerance, and face width.

The manufacturing process involved:

1. Material Selection: Choosing high-strength alloy steel for durability and fatigue resistance.
2. Turning Operations: Achieving accurate OD, bore, and hub dimensions.
3. Gear Cutting: Helical gear cutting using precision hobbing machines.
4. Heat Treatment: Carburizing and hardening for improved wear life.
5. Gear Grinding: Tooth grinding to ensure smooth meshing and noise reduction.
6. Inspection: Checking profile, lead, runout, and dimensional accuracy.

The outcome is a high-performance helical gear capable of transmitting power smoothly under continuous load.

💪 Manufacturing Challenges

Helical gears demand greater precision compared to spur gears due to angled tooth geometry.

• Helix Angle Accuracy: Even a small error affects contact pattern.
• Tooth Profile Control: Essential for smooth and quiet operation.
• Heat Treatment Distortion: Managing dimensional changes after hardening.
• Concentricity: Maintaining perfect alignment between bore and gear teeth.
• Surface Finish: Required to reduce friction and noise.

Each challenge is addressed using advanced machinery, skilled operators, and strict quality control.
