Bevel gears are mechanical transmission devices with conical-shaped tooth surfaces, primarily used to change the direction of power transmission, typically in applications requiring a 90-degree angle of transmission. The shape of the gear is conical, making them suitable for transmitting power between intersecting shafts. Depending on the tooth surface, bevel gears can be classified into straight bevel gears, spiral bevel gears, and hypoid bevel gears. They are widely used in industries such as automotive, aerospace, marine, and mining equipment, especially in applications where high torque transmission is required, providing efficient and smooth power transfer.
The main advantages of bevel gears include high load capacity, reduced noise and vibration, and a long service life. They enable efficient power conversion in complex mechanical systems, particularly when space is constrained or when a change in transmission angle is needed. Additionally, bevel gears can be custom-designed to meet the precise requirements of various industrial applications.
Through precision machining and high-quality materials, bevel gears can operate stably under high loads and long operational periods, ensuring the reliability and efficiency of the equipment.
