PRODUCT INTRODUCTION

 

 

A spiral bevel gear is a type of bevel gear with curved, oblique teeth that mesh at an angle, designed to transmit power between two intersecting shafts (typically at a 90° angle). Unlike straight bevel gears-whose teeth are straight and radial spiral design of their teeth enables smoother, quieter operation and higher load capacity, making them critical in high-performance mechanical systems.

Key Characteristics

1. Tooth Design:

   • Teeth are curved and gradually engage, reducing impact load and noise.

   • Provides smoother power transmission compared to straight bevel gears.

2. Load Capacity:

   • Higher load capacity due to more teeth in contact at the same time.

   • Suitable for high-speed and heavy-load applications.

3. Efficiency:

   • Efficiency is slightly lower than straight bevel gears due to sliding motion, but still high (95-98%).

4. Precision & Manufacturing:

   • Requires specialised manufacturing (e.g., Gleason or Klingelnberg systems).

   • Usually ground or lapped for precision and low noise.

Applications

• Automotive differentials (rear axle drive)

• Aerospace gear systems

• Heavy machinery (construction, mining)

• Marine propulsion systems

• Industrial gear reducers
