Concept For Spline Axes
2021-03-191. Function: It is a kind of mechanical transmission. The function of the peace key, the semi-circle key and the oblique key is the transmission of mechanical torque.
2. Structure: There is a longitudinal keyway on the outer surface of the shaft, and the rotating part sleeved on the shaft also has a corresponding keyway, which can keep rotating synchronously with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shifting gears.
3. Application examples: in the brake and steering mechanism. There is also a retractable shaft consisting of inner and outer tubes, the outer tube having internal teeth and the inner tube having external teeth and sleeved together. In use, it can be extended and contracted in the longitudinal direction while transmitting the rotational torque.
4, material: 40Cr
5. Heat treatment. Quenching surface hardness HRC45--50
