Mechanical Drive Gear Cylindrical Helical Gear For Gearbox And Differential
Gear for Gearbox, Car rear axle differential, and Mechanical transmission system
Characteristics of cylindrical gears:
Geometry: The tooth surface of cylindrical gears is straight and the tooth shape is cylindrical.
Transmission mode: The transmission of cylindrical gears is parallel axis transmission, that is, the axes of the two gears are parallel to each other.
Noise and vibration: Since the tooth surface is straight, large noise and vibration will be generated during transmission.
Simple manufacturing: The manufacturing process of cylindrical gears is relatively simple and easy to mass produce.
Application range: Widely used in various mechanical transmission systems, especially in low-speed and heavy-load occasions.
Characteristics of helical gears:
Geometry: The tooth surface of helical gears is spiral and the tooth shape is oblique cylindrical.
Transmission mode: The transmission of helical gears is staggered axis transmission, that is, the axes of the two gears intersect each other.
Noise and vibration: The spiral teeth of helical gears can reduce the impact during transmission, reduce noise and vibration.
Carrying capacity: The carrying capacity of helical gears is higher than that of cylindrical gears because they have a larger contact area.
Manufacturing complexity: The manufacturing process of helical gears is more complicated than that of cylindrical gears, and the cost is also higher.
Applications of cylindrical gears and helical gears:
Application of cylindrical gears: Commonly used in simple mechanical transmission systems, such as automobile gearboxes, transmission devices of industrial machinery, etc.
Application of helical gears: Due to their good load-bearing capacity and shock-absorbing effect, helical gears are often used in high-speed, high-load transmission systems, such as automobile rear axle differentials, heavy industrial machinery, etc.
