This design helps distribute the load evenly across the tooth surfaces, reducing stress concentrations and improving load-carrying capacity. Crowned splines are used in applications where high load capacity and resistance to wear are essential, such as heavy-duty gearboxes, marine propulsion systems, or mining equipment.

6. Ball Splines:

Ball splines incorporate recirculating ball bearings within the spline nut and grooves on the shaft. This design enables linear motion with low friction and high precision. Ball splines are commonly used in applications that require smooth linear motion, such as CNC machines, robotics, or linear actuators.

7. Custom Splines:

In addition to the standard spline profiles mentioned above, custom spline profiles can be designed for specific applications based on unique requirements. Custom splines can be tailored to optimize torque transmission, load distribution, misalignment compensation, or other specific performance parameters.

The choice of spline profile depends on factors such as the magnitude of torque, required accuracy, misalignment tolerance, noise and vibration considerations, and environmental conditions. Engineers and designers carefully select the appropriate spline profile to ensure optimal performance and reliability in the intended application.
