How to Measure a Splined Shaft

Measuring a splined shaft involves several steps that need to be followed meticulously. Here’s a step-by-step guide:

  1. Determine the diameter of the shaft using a caliper.
  2. Count the number of splines on the shaft.
  3. Measure the distance across the splines using a micrometer.
  4. Calculate the pitch of the splines by dividing the diameter by the number of splines.
  5. Measure the length of the shaft using a measuring tape or ruler.

Different Types of Spline Shafts


There are several types of spline shafts, each with distinct features.

Parallel Key Shaft

Parallel Key Shaft is known for its simplicity and ease of manufacturing. It’s ideal for low to medium load applications.

Spline Shaft with Involute Spline

Spline Shaft with Involute Spline boasts of high torque transmission, reduced stress concentration, and quiet operation.

Internal Spline Shaft

Internal Spline Shaft is characterized by its internal splines that allow for a tighter fit and enhanced torque transmission.

Non-circular Spline Shaft

Non-circular Spline Shaft is used in special applications where non-circular motion is required.

Choosing the Right Spline Shaft

Several parameters need to be considered when selecting a spline shaft, including:

  • Shaft Diameter: Determines the amount of torque that can be transmitted.
  • Spline Type: Defines the specific application of the shaft.
  • Number and Size of Splines: Affects the load distribution and torque capacity of the shaft.
  • Shaft Length: Influences the alignment and fit in the application.
  • Material: Determines the strength, durability, and resistance to wear and tear.
  • Surface Treatment: Enhances the lifespan and performance of the shaft.
