The Gear Shaft refers to the transfer of the whole machine and rotate it all the way to transfer the motion, torque or bending moment of the machine. As usual metal rods, each section can have different sizes of diameter. The parts of the machine for slewing motion are mounted on the shaft.

In the plan, the application of the gear shaft is usually no different from the following environments:

1. Gear shafts are usually small gears (gear with few teeth).

2, the gear shaft is usually at the high speed level (that is, low torque level).

3, the gear shaft is usually rarely used as a variable-speed sliding gear, as usual are firmly operating gears, one is due to high speed, its high speed is not suitable to stop sliding speed.

4. Gear shafts are shafts and gears as a whole, however, in the planning, or to try to shorten the length of the shaft; too long, one is not good for the hobbing machine processing, the second is the shaft support too long will incur the shaft to be thickened and increase mechanical strength (such as rigidity, deflection, bending, etc.).

Processing gear shaft, as usual process is: casting, normalizing, playing center empty (length may be more than 300, if short, the rough car is able to both ends of the car), rough car, flaw detection, modulation, precision car, hobbing, clamp repair, carburizing, repair intermediate hole, car carbon layer (spline standard requires hardness low, toughness good), quenching ( Gear standards require high hardness, hit load, short life span, sandblasting, milling key, clamp repair, training intermediate hole, grinding round by section, grinding teeth, clamp repair, inspection, flaw detection. Processing all kinds of gear shaft look for titanium hao machinery, the above process requirements for such as 20CrMnTi, 20CR2NI4, such as low-carbon steel materials.
