Gearbox Drive Shaft

This gearbox drive shaft is the primary active component in a shuttle shift transmission. It enables quick switching between forward and reverse. At Yancheng Botu Transmission Machinery, we manufacture this shaft from 20CrMnTi or 42CrMo steel. It undergoes carburizing and quenching, followed by precise grinding. The gear and spline are machined to DIN 7 accuracy, ensuring smooth shifts and reliable engagement. A robust gearbox drive shaft significantly enhances your machine's performance.

The shaft features a carburized layer of 0.8–1.2 mm with a surface hardness of HRC 58–62, providing excellent resistance to wear from constant shifting. Precision machining of the gear and spline reduces shift shock, while high-quality steel and deep hardening prevent breakage under accidental overload. This gearbox drive shaft is engineered for the demanding conditions of farm and construction equipment.

With 8 years of experience in transmission components, we understand the stresses caused by frequent shifting. That is why we optimize case depth and gear tooth design. Orders start at 50 pieces, and mixed orders are supported, allowing different models in a single minimum order quantity-ideal for buyers seeking repair parts. Each step of production is carefully inspected: tooth shape before heat treatment, hardness and distortion after heat treatment, and final size check after grinding. Any part failing to meet standards is reworked free of charge.
