what is spline shaft？
splined shaft is a mechanical component commonly used in manufacturing and industrial applications for transmitting torque. It features a series of equally spaced grooves or teeth known as splines machined along its length. These splines interlock with corresponding grooves in a mating component, such as a gear or coupling, allowing for efficient torque transfer while maintaining precise alignment

Types of Splines shaft
1. Parallel Key Splines
These splines feature equally spaced grooves with sides that are parallel in both the radial and axial directions. They are simple in geometry and commonly used for general purpose torque transmission.
2. Involute Splines
Involute splines have equally spaced grooves with sides shaped like an involute curve, similar to involute gears but typically shorter in height. This design helps reduce stress concentrations, thereby improving load capacity and strength.
3. Crowned Splines
Crowned splines are typically based on involute geometry, but the male teeth are slightly crowned (curved) to accommodate angular misalignment between mating parts. This modification enhances the durability and performance in misaligned conditions.
4. Serrated Splines
These splines have V shaped grooves and are primarily used on small diameter shafts. Their geometry allows for a high torque transfer capability in compact applications.
5. Helical Splines
Helical splines shaft feature grooves that follow a helical path around the shaft. The sides of the grooves may be either parallel or involute. This type of spline is ideal for high load applications requiring minimal stress concentration, or for assemblies requiring both rotary and linear motion.
6. Ball Splines
Ball splines consist of grooves in both the inner and outer components that act as linear races for ball bearings. This configuration enables smooth linear motion under high torque. For extended travel, recirculating ball channels can be integrated into the outer spline, allowing torque transmission along the entire length of a long shaft.
