Bevel Gears – 4 MOD | Spiral & Straight Bevel Gears

At Bolton Engineering Products Ltd, we supply precision-engineered Bevel Gears (4 MOD) designed for efficient power transmission between intersecting shafts. These gears are commonly used where a change in direction of rotation is required—typically at 90°, though other angles are also possible.

Our 4 module bevel gears are manufactured for strength, accuracy, and long service life in industrial and mechanical applications.

What Are Bevel Gears?

Bevel gears are toothed member that transfer force and motion between two intersecting axes. In addition to redirecting motion, bevel gears can also change speed and torque between the driver and the driven gears (input and output).

Types of Bevel Gears Available (4 MOD)

Spiral Bevel Gears

A spiral bevel gear has curved teeth set at an angle, allowing smoother engagement.

Key advantages:

• Higher load-carrying capacity
• Quieter operation with reduced vibration
• Better suited for continuous and high-speed applications

Straight Bevel Gears

A straight bevel gear features straight teeth aligned with the pitch cone.

Key advantages:

• Simple, robust design
• Cost-effective solution
• Suitable for lower speeds and intermittent operation
• Available in smaller diameters

Typical Applications of 4 MOD Bevel Gears

• Industrial machinery
• Gearboxes and transmission units
• Agricultural equipment
• Conveyors and material handling systems
• Machine tools
• Automation and mechanical assemblies

FAQs

1. What is the difference between spiral and straight bevel gears?

Spiral bevel gears offer smoother, quieter operation and higher load capacity, while straight bevel gears are simpler and more economical.

2. What does 4 MOD mean in bevel gears?

4 MOD refers to the gear module, defining tooth size and spacing for compatibility with other 4-module gears.

3. Are bevel gears used only at 90° angles?

No. While 90° is most common, bevel gears can operate at other shaft angles.

4. Can bevel gears change speed and torque?

Yes. Depending on the gear ratio, bevel gears can increase or reduce speed and torque
