What are Bevel Gears
There are two types of bevel gearboxes which include either straight or spiral teeth bevel gears. Straight bevel gears have straight and tapered teeth and are used in applications requiring slow speeds. Spiral bevel gears have curved and oblique teeth and are used in applications requiring high-performance, high speed applications.
Bevel Gears Applications
Bevel gears are mainly used in right-angle applications with the shafts in a perpendicular arrangement. The following are industries that use bevel gears within gearboxes:

• Print Press
• Power Plants
• Automobiles
• Steel Plants
• Hand Drills
• Differential Drives
Advantages and Disadvantages
Advantages of Bevel Gears

• Right-angle configuration
• Durable

Disadvantages of Bevel Gears

• Axes must be able to support forces
• Poorly cut teeth may result in excessive vibration and noise during operation
Physical Properties of Bevel Gears
Bevel gears are typically constructed from cast iron, aluminum alloy or other steel materials but vary between manufacturers.

Note: Bevel gears made from steel materials can be noisy when coming into contact with other gears, which also make them prone to wear.

Advantages and Disadvantages
Advantages of a Planetary Bevel Gear: • High power density • Compact • Highly efficiency in power transmission • Greater stability • Load distribution among planetary bevel gears Disadvantages of a Planetary Bevel Gear: • High bearing loads • Complex design • Inaccessibility
Physical Properties
The sun, ring and planetary bevel gears of a planetary bevel gearbox are constructed of aluminum, stainless steel or brass. The material used varies depending on the manufacturer. Note: A planetary bevel gear is made from steel materials can be noisy when coming into contact with other gears, which make them prone to wear.
Advantages and Disadvantages
Advantages of Planetary Bevel Gears: • High power density • Compact • Highly efficiency in power transmission • Greater stability • Load distribution among planetary gears Disadvantages of Planetary Bevel Gears: • High bearing loads • Complex design • Inaccessibility
Applications
Gearboxes using planetary bevel gears are used in applications requiring low backlash, compact size, high efficiency, resistance to shock, and a high torque to weight ratio. The following are examples of applications using planetary bevel gears: • Slewing Drives • Lifts • Cranes • Machine Tools • Automotive
Physical Properties
The sun, ring and planetary bevel gears of a planetary gearbox are constructed of aluminum, stainless steel or brass. The material used varies depending on the manufacturer. Note: Planetary bevel gears made from steel materials can be noisy when coming into contact with other gears, which make them prone to wear.
What are Planetary Bevel Gears
Planetary gearboxes are named so due to their resemblance to the solar system. The components of a planetary gearbox include a sun gear, ring gear and planetary bevel gears. The sun gear is the central gear which is fixed in the center, ring gear (annulus ring) which is the outer ring with inward-facing teeth; the planetary bevel gears rotate around the sun gears and mesh with both the sun and ring gear.
Physical Properties
The sun, ring and planetary bevel gears of a planetary gearbox are constructed of aluminum, stainless steel or brass. The material used varies depending on the manufacturer. Note: A planetary gear is made from steel materials can be noisy when coming into contact with other gears, which make them prone to wear.
Advantages and Disadvantages
Advantages of Spur Bevel Gears: • Cost-effective • High gear ratios • Compact • High torque output Disadvantages of Spur Bevel Gears: • Noisy • Prone to wear
Applications
Spurs Bevel Gears are used in applications requiring a decrease in speed with high output torque. The following are examples of typical applications of Spur Bevel Gears: • Cut-to-Length • Packaging • Speed Control • Construction • Power Plants
Physical Properties
Spur Bevel Gears are typically constructed from metals such as steel or brass, and plastics such as nylon or polycarbonate. The material used to construct spur bevel gears may vary depending on the manufacturer. Note: Spur Bevel Gears made from steel materials can be noisy when coming into contact with other gears, which make them prone to wear.
What are Spur Bevel Gears
Spur Bevel Gears are made with straight teeth mounted on a parallel shaft. The noise level of spur bevel gears is relatively high due to colliding teeth of the gears which make the teeth of spur bevel gears prone to wear. Spur Bevel Gears come in a range of sizes and gear ratios to meet applications requiring a certain speed or torque output.
