The half shaft is the core transmission component of the drive axle in construction machinery, responsible for transmitting differential power to the drive wheels. It needs to withstand high torque, impact loads, and bending moments, and is commonly used in heavy equipment such as excavators, bulldozers, and cranes; According to the support form, full floating (only torque transmission) or semi floating (torque transmission+bending) are commonly used, and high-strength alloy steels such as 40Cr and 42CrMo are mainly used as materials

Application characteristics: The working environment of construction machinery half shafts is harsh (mud, vibration, heavy load), requiring high fatigue strength and resistance to bending and twisting; Fully floating type is used for overloaded equipment (such as mining trucks), which is easy to maintain and the bridge shell does not bear bending; Semi floating is used for medium-sized machinery such as excavators, with a compact structure but complex stress distribution.

Key points of production process: The product is mainly produced by forging, which can improve the intergranular structure, enhance mechanical properties, and save materials and machining allowances. Then, it undergoes heat treatment quenching and tempering, precision machining, threading or gear, sprocket and other transmission structures, and final heat treatment hardening treatment to reduce wear and improve the service life of the product.

There is also a type of mixing shaft, which is a commonly used power output component in industries such as chemical and agricultural machinery.

The stirring shaft is the core transmission component in chemical machinery that transmits torque, drives the stirring blade to achieve material mixing, heat and mass transfer. It is widely used in equipment such as reaction vessels, mixers, and dissolution tanks, supporting key processes such as homogenization, reaction acceleration, suspension dispersion, and gas-liquid contact in chemical production.
