A gearbox for construction machinery is a torque and power transmission system that transfers engine output to wheels or rollers. Gears are made of alloy steel with surface hardness of 55–62 HRC and machining precision under 0.01 mm. Gear ratios range from 4:1 to 20:1, transmitting up to 500 horsepower. The gearbox housing is made of cast steel or hardened aluminum with anti-wear and corrosion-resistant coatings. Lubrication uses hydraulic or gear oil with viscosity of 68–150 cSt, extending component life to over 8000 hours.

The gearbox includes input and output shafts, helical and bevel gears, ball and roller bearings, and mechanical seals. High assembly precision and dynamic balancing reduce vibration and noise. Internal or external cooling maintains operating temperature between 60–90°C. Modular design allows fast servicing and replacement of wear parts. Optimized for bulldozers, loaders, and graders, the gearbox achieves power transmission efficiency above 90 percent.You can order and buy transmission from Iran by contacting us through whatsaap and email.
