Product Description

Product Description

Mechanical Transmission Gearbox- QTJF15/20/25/30 Series
Suitable for 1.5tons – 3 tons diesel forklift.
1)Driving axle integrated transmission can make the power plant including engine, transmission and reducer float on the vehicle body.
2)Split-type layout connected by damping block and universal coupling leads to low vehicle vibration and eases driver’s fatigue.
3)Sliding (Inertial lock-ring) synchronizer makes the shifting more flexible and has less impact.
4)The transmission has good bearing capacity, high transmission efficiency and stable operation.
5)Housing made of alloy cast iron has a beautiful appearance .
6)Application of evanescent mode and coated- sand solves the problem of raw material defect.

What is a Gearbox and How Does It Work?

A gearbox is a mechanical device that transmits power and changes the speed or torque of a rotating input shaft to a different output shaft. It is commonly used in various machines and equipment to control the speed and direction of motion.

Here’s how a gearbox works:

  1. Input Shaft: The gearbox receives rotational energy from an input shaft connected to a power source, such as an electric motor or an engine.
  2. Gears: Inside the gearbox are a set of gears with different sizes. These gears mesh with each other, and their arrangement determines the gear ratio, which defines how many revolutions the output shaft will make for a given rotation of the input shaft.
  3. Output Shaft: The output shaft is connected to the machinery or equipment that needs to be powered. As the gears rotate, the motion and power are transmitted from the input shaft to the output shaft.
  4. Gear Ratio: By selecting different gear combinations, the gearbox can change the speed and torque of the output shaft. A higher gear ratio results in higher torque and lower speed, while a lower gear ratio provides higher speed and lower torque.

Gearboxes play a crucial role in various applications, including automobiles, industrial machinery, robotics, and more, enabling efficient power transmission and speed control.
