is splined shaft diameter measured outside or inside diameter


Understanding Spline Shaft Diameter Measurements and Its Implications

A Deep Dive Into Spline Shaft Diameters

When it comes to measuring the diameter of a spline shaft, it is typically referred to the outside, or major, diameter. This is the total diameter across the outermost points of the splines. The inside, or minor, diameter refers to the total diameter across the base of the splines. Understanding these measurements is crucial in the design and application of spline shafts.

Our Premium Spline Shafts

We take pride in producing high-quality spline shafts. Here are five key features of our products:

Diverse Types of Spline Shafts and Their Features

We offer a range of spline shafts to suit different applications. Here’s a closer look at some of them:

Parallel Key Shaft

This type of shaft is characterized by parallel splines for secure torque transmission.

Spline Shaft with Involute Spline

These shafts feature curved splines, providing a smoother engagement with the mating component.

Internal Spline Shaft

These shafts have internal splines and are typically used in gearboxes and other similar applications.

Non-circular Spline Shaft

These are customized shafts with non-circular splines to suit unique requirements.

Selecting the Right Spline Shaft

Choosing the right spline shaft involves understanding several parameters:

  • Shaft Diameter: It is crucial to choose a shaft with the correct diameter to ensure proper fit and function.
  • Spline Type: The type of spline affects the torque transmission and the smoothness of the operation.
  • Number and Size of Splines: These affect the load distribution and the strength of the shaft.
  • Shaft Length: The length of the shaft should be chosen based on the specific application.
  • Material: The material choice affects the durability and performance of the shaft.
  • Surface Treatment: This can enhance the wear resistance and longevity of the shaft.
