Understanding Bevel Gear Parameters
Key terms for specifying bevel gears, which operate on intersecting shafts. Unlike spur gears, bevel gears have a conical geometry, introducing unique parameters.
| Term | Definition & Use |
|---|---|
| Gear Ratio | Ratio of teeth on the gear to teeth on the pinion. Determines speed/torque change. |
| Shaft Angle (Σ) | The angle between the two intersecting gear shafts, typically 90°. |
| Pitch Cone | The imaginary cone on which the tooth profiles are based. The pitch angles of mating gears must sum to the shaft angle. |
| Cone Distance (A) | The distance from the cone apex to the outer edge of the teeth. Must be the same for both gears in a set. |
| Module / DP | Defines the tooth size, measured at the large end (heel) of the gear tooth. Must match for both gears. |
| Contact Pattern | The area where mating teeth make contact. Controlled by lapping, it's critical for load distribution and gear life. |
| Mounting Distance | A critical dimension from the cone apex to a locating surface on the gear, ensuring correct meshing. |
Why Lapping is Critical for Spiral Bevel Gears
After heat treatment, minor distortions can occur in the gear teeth. Lapping is a finishing process where the gear and pinion are run together with an abrasive compound. This smooths the tooth surfaces and perfects their geometry, creating an ideal "contact pattern." A good contact pattern ensures the load is distributed evenly across the tooth, leading to quieter operation, lower stress, and significantly longer service life. This is why we always supply bevel gears as factory-matched and lapped sets.
Frequently Asked Questions
Bevel gears are conical gears that transmit power between intersecting shafts, usually at a 90° angle. They are widely used in automotive differentials, machine tools, marine drives, and industrial gearboxes.
The main types include straight bevel gears, spiral bevel gears, and hypoid gears. Straight bevel gears are simple and cost-effective, spiral bevel gears offer smoother and quieter operation, while hypoid gears allow higher torque transmission with offset shafts.
Straight bevel gears have straight teeth and are ideal for moderate speeds and loads. Spiral bevel gears have curved teeth, which engage gradually, resulting in smoother, quieter operation and a higher load capacity, making them suitable for demanding, high-speed applications like automotive differentials.
Use a bevel gear for efficient right-angle power transmission (90–98% efficiency) where high gear ratios are not required. Use a worm gear for high reduction ratios and self-locking applications, though efficiency is lower.
Bevel gears are manufactured and lapped together as a pair (pinion and gear) to ensure a perfect tooth contact pattern. Using gears from different sets can cause poor meshing, noise, and rapid wear.
Bevel gears are typically made from alloy steels such as EN19, EN24, EN353, 16MnCr5, 20MnCr5, and SAE 8620. These materials are often case-hardened to increase strength and wear resistance.
Industries such as automotive, aerospace, mining, construction, marine, robotics, and power transmission commonly use bevel gears in their machinery and drive systems.
Spiral bevel gears are used in high-speed, high-load applications requiring smooth torque transfer. Examples include automotive differentials, helicopters, aerospace gear systems, and precision industrial machinery.
Specifications include gear type (straight or spiral), gear ratio, module/DP, shaft angle, material, bore size, and any heat treatment requirements. Providing accurate details ensures proper design and performance.
Hypoid gears are similar to spiral bevel gears but have an offset pinion shaft. This design allows higher torque capacity, smoother motion, and higher reduction ratios, making them common in automotive rear axles.
Spiral bevel gears offer higher load capacity, quieter operation, smoother torque transfer, and longer lifespan compared to straight bevel gears, making them ideal for heavy-duty machinery.
Bevel gears are manufactured using Gleason or Klingelnberg cutting machines, followed by heat treatment (carburizing or hardening), and lapping to ensure precise tooth contact and durability.
Shreeji Gears manufactures bevel gears up to 800 mm in diameter, suitable for various heavy-duty industrial applications.
Yes, bevel gears generate axial thrust and radial loads. Bearings like tapered roller bearings are typically used to handle these forces and maintain alignment.

The Shreeji Gears Advantage
Our expertise in right-angle drive technology ensures your machinery performs reliably.
Right-Angle Drive Expertise
We understand the unique challenges of bevel gears, from managing axial thrust loads to ensuring precise shaft alignment. We select the right alloy steels and hardening processes to handle the complex forces inherent in right-angle power transmission, guaranteeing a robust and reliable gear set.
Advanced Lapping & Matching
A bevel gear is only as good as its contact pattern. Our advanced manufacturing includes Gleason cutting and a critical lapping process. We meticulously lap each gear and pinion pair together to create the perfect tooth surface and contact, drastically reducing noise and maximizing gear life.
Matched Set Guarantee
We never sell a bevel pinion or gear individually. Every set we produce is born together, heat-treated together, and lapped together. This commitment to providing factory-matched sets guarantees performance, simplifies your assembly, and eliminates the risk of premature failure from mismatched components.

Bevel gears are essential components for applications that demand smooth, efficient power transfer between intersecting shafts.
What is a Bevel Gear?
Bevel gears are gears designed with a conical pitch surface, enabling them to transmit motion and power between shafts that intersect—most commonly at a 90° angle. This makes them indispensable in machinery where a change in shaft direction, torque adjustment, or speed variation is required. They are widely used in industrial gearboxes, automotive differentials, mining equipment, and aerospace applications.
Types of Bevel Gears
- Straight Bevel Gears: Featuring straight teeth that, if extended, meet at the cone apex, these are the simplest form of bevel gears. They are best suited for lower-speed applications where noise and vibration are not critical factors.
- Spiral Bevel Gears: With curved, angled teeth, spiral bevel gears provide gradual tooth engagement, resulting in quieter operation, higher load-carrying capacity, and smoother torque transmission—similar to the difference between spur gears and helical gears.
- Hypoid Gears: A special type of spiral bevel gear where the pinion is offset from the center, enabling higher reduction ratios and greater torque transmission. These are common in heavy vehicles and industrial drives.
Thrust Loads and Bearing Requirements
Bevel gears inherently generate axial thrust and radial forces during operation. This requires robust housing and proper bearings (such as tapered roller bearings) to ensure durability and performance. Our engineering team carefully calculates thrust loads and provides solutions tailored to your application for maximum system reliability.
