FAQS on differential side gear
Q: What is the function of a differential side gear in a vehicle's drivetrain?
A: The differential side gear transfers torque from the differential case to the axle shafts, enabling power distribution to the wheels. It works with the differential pinion gears to allow speed differences between wheels during turns.
Q: What causes wear or damage to differential side gears?
A: Common causes include insufficient lubrication, metal fatigue from prolonged use, or excessive load/impact from harsh driving conditions. Contaminated gear oil or misalignment of components can also accelerate wear.
Q: How do differential pinion gears interact with side gears?
A: Differential pinion gears rotate on the spider gear shaft and mesh with the side gears. This interaction allows opposing wheels to turn at different speeds while maintaining torque distribution during cornering.
Q: Can a worn differential side gear affect vehicle handling?
A: Yes, damaged side gears may cause grinding noises, vibration, or uneven power delivery. Severe wear can lead to axle binding, reduced traction, or complete drivetrain failure during sharp turns.
Q: How often should differential side gears be inspected?
A: Inspect during routine maintenance (every 30,000–50,000 miles) or if symptoms like whining sounds occur. Regular gear oil changes and visual checks for metal shavings in the fluid help prevent unexpected failures.

Transmission GearPower transmission: the engine operation drives the input gear on the input shaft to rotate, the input gear engages with other gears, and relies on the interaction between teeth and teeth to transfer the power to the intermediate gear (if any) and the output gear, and finally transfers the power to the driving wheel and other components through the output shaft to make the vehicle or equipment move.
Variable speed principle: Change the transmission ratio by meshing gears with different numbers of teeth. For example, when the big gear drives the small gear, the speed of the small gear will be faster than the big gear, but the output torque will be smaller, to achieve growth and torque reduction; On the contrary, when the pinion drives the big gear, the speed of the big gear slows down, the torque increases, and the torque increases. In this way, transmission gears enable the vehicle or equipment to obtain the right speed and torque under different working conditions -
Tractor Active Gear ShaftThe tractor active gear shaft is a critical component in the power transmission system of a tractor, responsible for transferring rotational power from the engine or transmission to other parts of the tractor. By efficiently distributing torque and enabling smooth gear shifts, the active gear shaft plays a vital role in enhancing the performance and versatility of the tractor, making it essential for a wide range of agricultural tasks. In this article, we’ll explore the function, benefits, and maintenance of the tractor active gear shaft.

Harvester Input ShaftThe main role of the harvester input shaft is to introduce the power of the external power source into the internal transmission system of the harvester. When the power source (such as an engine) is running, the torque generated is transmitted to the input shaft through the connecting parts, causing the input shaft to start rotating. The gear, pulley or sprocket and other transmission parts installed on the input shaft will rotate with the rotation of the input shaft, and then transfer the power to the subsequent transmission parts and working parts, such as driving the cutting device, conveying device, threshing device, etc., to complete the crop harvesting, conveying, threshing and other work processes.
