Mastering Spline Shafts in Solidworks: A Comprehensive Guide
Understanding ‘How to Spline a Shaft in Solidworks’
When it comes to solid modelling computer-aided design (CAD) and computer-aided engineering (CAE) software tools, SolidWorks stands out. It’s an effective tool for engineers and designers, particularly in creating a spline shaft. The process involves a series of steps, including:
- Opening a new part in SolidWorks.
- Sketching the profile of the spline shaft.
- Applying the Revolved Boss/Base feature.
- Defining the number of splines and their orientation.
- Using the Circular Pattern tool to evenly distribute the splines.
- Finalizing the design with the necessary fillets and chamfers.

Exploring Different Types of Spline Shafts

Parallel Key Shaft
This shaft type features parallel splines for simple and effective power transmission.
Spline Shaft with Involute Spline
With curved, involute splines, this shaft type provides smoother engagement and higher torque transmission.
Internal Spline Shaft
In this type, the splines are located inside the shaft, allowing for compact designs and increased load capacity.
Non-circular Spline Shaft
Non-circular spline shafts are designed for specialized applications, offering unique power transmission characteristics.

Choosing the Right Spline Shaft
When selecting a spline shaft, consider several parameters:
- Shaft Diameter: Dictates the shaft’s load capacity and compatibility with mating components.
- Spline Type: Influences the shaft’s torque transmission and operational smoothness.
- Number and Size of Splines: Affect the shaft’s load distribution and engagement characteristics.
- Shaft Length: Determines the shaft’s fit within the system.
- Material: Impacts the shaft’s strength, durability, and resistance to wear and corrosion.
- Surface Treatment: Enhances the shaft’s wear resistance, corrosion resistance, and overall lifespan.
