Mechanical Drive Gear Cylindrical Helical Gear For Gearbox And Differential
Gear for Gearbox, Car rear axle differential, and Mechanical transmission system
Spur gears and helical gears are two common types of gears used in mechanical transmission systems, and they play a key role in gearboxes.
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.
