High Reduction Ratio Hypoid Grinding Gear for Precision Industrial Gearboxes

High Reduction Ratio Hypoid Grinding Gear for Precision Industrial Gearboxes

High-reduction-ratio hypoid grinding gears are high-ratio staggered-axis gears manufactured through a precision grinding process. Their design combines the offset characteristics of hypoid gears with the compactness of worm drives, making them suitable for high-precision, high-load transmission scenarios.

Structural Features

The hypoid gear is characterized by non-intersecting and offset axes, creating a unique spatial geometry that extends the contact line and increases the number of meshing tooth pairs during operation.
This distinctive structure enables smoother torque transmission and higher load capacity.
After precision grinding, the tooth surface achieves exceptional accuracy, high smoothness, and minimal profile error, ensuring excellent performance and durability.

Performance Advantages

• High Reduction Ratio:
  Capable of achieving a large transmission ratio within a compact structure, the gear meets the demanding requirements of applications needing high torque and low speed, effectively reducing rotational speed while increasing torque output.

• Smooth and Low-Noise Transmission:
  Due to optimized meshing characteristics, the hypoid gear operates with minimal impact and vibration, ensuring stable power delivery and low noise, suitable for environments with strict noise control standards.

• Excellent Load-Bearing Capacity:
  The special geometric design combined with precision grinding significantly enhances both tooth surface contact strength and root bending strength, allowing the gear to perform reliably under heavy load and continuous-duty conditions.
