Motor Shaft Forging
A shaft end of a motor is a special drive shaft that is specially applied to motors. Motor shaft, is drive shaft in fact. It is a mechanical component for transmitting torque and rotation, usually used to connect other components in a motor.
As torque carriers, motor shafts are subject to torsion and shear stress, equivalent to the difference between the input torque and the load. They must therefore be strong enough to bear the stress, whilst avoiding too much additional weight as that would in turn increase their inertia.
To allow for variations in the alignment and distance between the driving and driven components, drive shafts frequently incorporate one or more universal joints, jaw couplings, or rag joints, and sometimes a splined joint or prismatic joint.
