Auxiliary Transmission Input Shaft

The Auxiliary Transmission Input Shaft brings power into the auxiliary gearbox. The gear and shaft are made as a single piece, taking torque from the main gearbox through the engine. At Yancheng Botu Transmission Machinery, we manufacture this shaft from forged 20CrMnTi steel. The gear is carburized and quenched, then precision-ground. Gear shape meets DIN 7 grade accuracy, ensuring smooth auxiliary shifts and efficient power transfer. A strong Auxiliary Transmission Input Shaft is essential for optimal gearbox performance.

We grind the gear to achieve DIN 7 grade accuracy for smooth engagement and low noise. The carburized layer is 0.8–1.2 mm deep with a surface hardness of HRC58–62, giving the gear high load capacity. Making the gear and shaft as a single piece eliminates assembly errors, improving rigidity and reliability. This Auxiliary Transmission Input Shaft is built for demanding work conditions.

Our 8,000㎡ factory and 45-person team handle all processes in-house, with monthly capacity of 2–3 million pieces. Full CNC equipment ensures accuracy, including gear hobbing machines, gear grinding machines, and CNC lathes. Each machine is regularly calibrated. From raw material to finished part, we conduct spot checks on tooth shape, direction, and case depth. Third-party inspections are welcome. Orders start at 50 pieces.
