Gears produced by machining have crucial applications in the transportation industry:
Automotive industry:
Transmission: Various gears in a car transmission, such as input shaft gears, output shaft gears, intermediate shaft gears, etc., are responsible for power transmission and speed adjustment in different gears to achieve smooth transmission and efficient driving of the vehicle.
For example, in manual transmissions, the precise machining of gears ensures smooth and accurate shifting.
Differential: The planetary gears and half axle gears in the differential allow the left and right wheels of the vehicle to rotate at different speeds when turning, ensuring stability and handling during driving.
The differential gears of high-performance cars typically use higher grade materials and more precise machining processes to withstand greater torque and provide better performance.
Engine: Gears are also used in the timing system of the engine to ensure accurate valve opening and closing time.
Motorcycle industry:
Transmission system: During the power transmission process from the engine to the rear wheels, multiple gears work together to achieve output of different speeds and torques.
The transmission gears of off-road motorcycles need to have stronger wear resistance and impact resistance, which can be achieved through machining.
Aerospace field:
Aircraft landing gear: Gears are used in the retraction and retraction system of the landing gear to achieve mechanical transmission.
Helicopter transmission system: In the complex transmission system of helicopters, high-precision gears are crucial for smooth power transmission and flight safety.
In the field of rail transit:
Train locomotive: In the traction and transmission systems of locomotives, large gears undertake a huge torque transmission task.
The gears in the gearbox of high-speed trains need to maintain extremely low noise and high reliability during high-speed operation.
Gears produced by machining play a crucial role in power transmission, speed change, and steering of transportation vehicles, and their quality and accuracy directly affect the performance, efficiency, and safety of transportation vehicles. For example, in some high-end car transmissions, high-precision machined helical gears can significantly reduce noise, improve transmission efficiency, and shift comfort.
