1) Description of Spline Gear Shaft
The splined shaft is a core component in mechanical transmission and is used in situations
where torque and relative motion need to be transmitted simultaneously.
2) Characteristics of Spline Gear Shaft
a) It is widely used in automotive gearboxes, construction machinery, aero engines, machine tool spindles, etc.
b) It can be designed as a fixed connection or a sliding connection (such as the drive shaft of a four-wheel drive vehicle).
3)Advantages of Spline Gear Shaft
a) Versatility: It not only supports static high torque transmission but also ADAPTS to dynamic axial movement (such as clutch control shafts).
b) Compact design: Saves space compared to keyway connections and is suitable for lightweight and highly integrated devices.
