Gear Shaft Forgings

Gear shaft forgings
I. product introduction
A gear shaft forging is a mechanical part that supports a rotating part and turns with it to transmit motion, torque, or bending moment. It is usually a round metal rod with different diameters. The rotating parts of the machine are mounted on the shaft. Gear shaft forging is the shaft and gear synthesis of a whole, but, in the design, or to shorten the length of the shaft, too long is not conducive to hobbing machine processing, the second is the support of the shaft is too long to lead to the shaft to be thick and increase the mechanical strength (such as rigidity, deflection, bending, etc.).

Iii. Product advantages
In the process of gear shaft forging, the selection of positioning reference should be considered as follows: at the beginning, the outer circle should be used as the center hole of the end face of the rough reference to prepare positioning reference for the rough car; The rough turning outer circle is the positioning reference for the subsequent processing: after that, in order to prepare the positioning reference for the semi-finishing and finishing outer circle, the center hole before and after processing is used as the positioning reference. Gear shaft forgings also use the center hole as the positioning reference, which is a very good embodiment of the principle of unity of reference, also fully embodies the principle of coincidence of reference.


In the whole process of shaft machining, enough heat treatment procedures should be arranged to ensure the mechanical properties of gear shaft and machining accuracy requirements, and improve the workpiece processing properties.
In general, normalizing treatment is arranged first after shaft blank forging to eliminate the internal stress of forging, refine the grain and improve the cut
