Parallel Shaft and Right Angle Helical Gearbox Manufacturer - Shreeji Gears

Precision Helical Gearboxes

Shreeji Gears is a prominent helical gearbox manufacturer, providing robust and efficient solutions for industrial power transmission. Helical gearboxes use helical gears, known for their smooth engagement and high efficiency, making them ideal for speed reduction and torque multiplication.

We design and manufacture both parallel shaft and right-angle helical gearboxes. Our gearboxes are built with high-quality materials and precision engineering to ensure reliability and long service life in demanding environments.

Understanding Helical Gearboxes

Helical gearboxes are enclosed systems containing helical gears designed to reduce speed and increase torque from a motor to a machine. The angled teeth of helical gears engage gradually, leading to smoother, quieter operation and higher load-carrying capacity compared to spur gears.

Common Configurations:

  • Parallel Shaft Helical Gearbox: Input and output shafts are parallel. These use multiple stages of helical gears to achieve the desired reduction ratio and are known for very high efficiency.
  • Right-Angle Helical Gearbox: Input and output shafts are perpendicular. These often combine a bevel gear input stage with subsequent helical gear stages for reduction (Bevel-Helical).

Advantages:

  • High Efficiency: Helical gears offer excellent efficiency, minimizing power loss (typically 95-98% per stage).
  • Smooth & Quiet Operation: Gradual tooth engagement reduces noise and vibration.
  • High Load Capacity: Can transmit significant torque due to greater tooth contact.
  • Durability: Properly designed helical gearboxes offer a very long service life.
