Bevel Gear Reducers

Feida bevel gear reducers are a type of speed reduction device that uses bevel gears as the main transmission components and achieves power transmission and speed reduction through gear meshing. They are suitable for intersecting shafts or specific crossed shaft transmission scenarios.

Basic working process : Power is input by an electric motor or other power source, transmitted through the input shaft to the driving bevel gear, and then transmitted to the output shaft through the meshing of the driving gear and the driven bevel gear. Due to the different number of teeth between the driving wheel and the driven wheel, the rotational speed of the output shaft decreases, while the output torque increases accordingly.

Main Structure

Main Characteristics

Ability to Change the Direction of Power Transmission

One of the most distinctive features of bevel gear reducers is their ability to transfer power between intersecting shafts, making them particularly suitable for mechanical structures where the input shaft and the output shaft form a 90° angle. This feature makes it have high application value in devices with limited spatial layout.

Compact Structure and Flexible Layout

They are used to change the direction of power transmission and reduce speed within a relatively small space, facilitating compact equipment design.

Relatively High Transmission Efficiency

With reasonable design, high processing accuracy and good lubrication, bevel gear transmission can maintain high mechanical efficiency and is suitable for equipment with certain requirements for energy loss.

Strong Load-Carrying Capacity

Spiral bevel gear reducers, in particular, provide smooth meshing and a relatively high contact ratio, which allow them to withstand substantial transmission loads and operate under continuous industrial conditions.

High Requirements for Manufacturing and Installation Precision

They require more precise manufacturing, assembly, and adjustment than conventional straight cylindrical gear transmissions because the tooth geometry of bevel gears is relatively complex.

Significant Axial Forces

Bevel gear meshing generates not only radial forces but also axial forces, especially in spiral bevel gear transmission. Therefore, bearing type, bearing arrangement, and shaft-system stiffness must be carefully considered during design.

Manufacturing Process

Feida has more than 30 years of experience in the transmission parts industry, producing bevel gear reducers in accordance with ISO 9001:2015 quality management system .

Our manufacturing process is a systematic project that covers everything from component processing to the assembly, commissioning and inspection of the entire machine.
