Types of Bevel Gears & Their Benefits

Types of Bevel Gears & Their Benefits

A bevel gear is one of the most versatile types of gear, used in a variety of mechanical applications. They transmit power and motion between shafts at different angles, making them an important component in machines. There are several types of bevel gears available on the market today, each with its own set of benefits. We explore in this blog the common types of these gears and the benefits that they offer.

Different Types of Bevel Gears

Straight bevel gear:  They have a conical shape with their teeth forming straight lines. These are used for applications such as driveshafts, pumps, and elevators. Some of the most significant features of straight gears are that they are relatively simple to manufacture, and often require only a single gear set.

Spiral bevel gear:  They have a curved or helical shape with their teeth forming a spiral. These types of gears provide greater efficiency than their straight counterparts and are used in applications such as automobiles, aircraft, and industrial equipment. The main benefit of these gears is that their teeth can be designed to have higher contact ratios, meaning more contact between the two meshing teeth which reduces noise and vibration.


The Benefits of Different Types of Bevel Gears

Benefits of straight bevel gear: They provide a high degree of power transmission efficiency. They can transmit more power than helical gears, and the space requirements are much less than for worm gears. They also allow for higher speeds due to their smooth operation.

Benefits of spiral bevel gear: They provide greater load-carrying capacity than straight gears, making them ideal for applications that require higher torque or force. They produce nearly no noise when compared to other types of gearing systems, making them suitable for applications where quiet operation is desired.



Bevel gears are an essential component of many mechanical systems, and their importance cannot be overstated. They are mainly classified into two types; straight and spiral. Each type has unique features that make it suitable for specific applications. You can rely on us at True Gear & Spline Ltd. for all your gear and spline shaft needs.
