Geared(Spline) Shaft Milling
A particular type of mechanical transmission is the Spline Shaft. It serves the same purpose as the wedge key, semicircular key, and flat key. Each one of them produces mechanical torque. The surface of the shaft has longitudinal keyways. synchronise your rotation with the axis. Some spinning objects, such gearboxes that change gears, can also glide longitudinally on the shaft.
1. Purpose: It serves as a type of mechanical transmission. The same functions—transmitting mechanical torque—are performed by flat, semicircular, and oblique keys.
2. Design: The shaft has a longitudinal keyway on its surface, and the spinning component sleeved on the shaft has a keyway of its own that can maintain synchronous rotation with the shaft. Some objects, like gearboxes that change gears, can move longitudinally on the shaft while they are spinning.
3. Application examples: in the steering and braking systems. There is also a retractable shaft that consists of inner and outer tubes that are sleeved together and have inner and outer teeth on each tube. It may be stretched and compressed while transferring rotating torque.
4. Material: 40Cr.
5. Heat treatment. Quenching surface hardness HRC45--50.
