SuNPe is a professional machining manufacture. What is Spline and what types of Spline does SuNPe can do for you? Let’s learn from this article.
 

What is Spline?


A spline connection consists of an inner and an outer spline. Both internal and external splines are multi-tooth parts, the spline on the inner cylinder surface is the internal spline, and the spline on the outer cylinder surface is the external spline. Splines are generally used when both linear and rotational motion is desired. There are various types of splines used for numerous industrial applications.

Types of Spline Shaft:


There are 3 types spline SuNPe can do for you:
 

(1)Parallel Spline


This type has equally spaced teeth that are straight sided. It’s easy to process, grinding method can be used to achieve higher accuracy. But spline broaches are usually used and unable to process no thru hole’s spline. For the no thru hole’s spline, it only can use slotting processing, but the accuracy is low.

(2)Involute Spline


This type has equally spaced teeth, but they are not straight sided. The tooth pro profile is involute. The teeth do not have the same proportions as a gear tooth, they are shorter in height. The processing is the same as gear. It’s easy to achieve high precision and interchangeability This type’s spline is widely used.

(3)Triangular Spline


These splines are the inner spline tooth shape is triangular. The pressure angle is equal to 45°of involute. This type of spline is easy to process. Tiny teeth and more that it’s easy to adjust and assemble. Mainly used for light load and small diameter static connection, especially suitable for shaft and thin wall parts connection.
