The working principle of a bevel gear is based on the transmission of rotational motion between shafts that are typically at right angles to each other. Bevel gears have conical shapes, allowing them to mesh smoothly. When one bevel gear is rotated, its teeth engage with the teeth of another bevel gear, transferring motion and torque from one shaft to the other. This design allows for changes in the direction of the drive, making bevel gears essential in various mechanical systems, such as in differentials in vehicles.

1. Working Principle of Straight Bevel Gears According to the design of bevel gears, they are divided into straight and spiral teeth. The design, manufacturing, and installation of straight bevel gears are relatively simple. However, a downside is that they produce more noise. They can be used in low-speed machines. During operation, their transmission runs stably and they are widely applied. 2. Working Principle of Spiral Bevel Gears Unlike straight bevel gears, the design of spiral bevel gears is more complex. However, their advantage is that the entire transmission runs smoothly. Compared to straight bevel gears, they produce much less noise and have a greater load capacity, making them suitable for high-speed heavy-load applications. The transmission power is greater than that of straight bevel gears. 3. Installation of Bevel Gears During the installation of bevel gears, the center lines of the two shafts should first be adjusted to the same plane to facilitate installation. Then, adjust the gear clearance. After that, adjust the shaft runout. Use a special feeler gauge to check. A slight deviation is acceptable. If the deviation is too large, the installation of the bevel gears will fail. Check for any unusual noises when the gears rotate. Choosing the right gears can achieve twice the result with half the effort in mechanical operations. As a common transmission mechanical component, there are many types of gears, among which bevel gears need to be carefully checked after installation.
1. The working principle of straight bevel gears
According to the design of bevel gears, they are divided into straight and helical types. The design, manufacturing, and installation of straight bevel gears are relatively simple. However, one downside is that they tend to be noisier. They can be used in low-speed machines. During operation, their transmission runs stably and they are widely used.
2. The working principle of helical bevel gears
Unlike straight bevel gears, the design difficulty is a bit higher. However, its advantage is that the entire transmission runs smoothly. Compared to straight bevel gears, it is much quieter, has a greater load capacity, and can be used in some high-speed heavy-load situations. The transmission power is greater than that of straight bevel gears.
