Square Splines

These simple connections are used mainly for transmitting light loads, and where accurate positioning is not critical. A cap screw is required to hold the enveloping part.

Serrations

Small size serrations are also used to transmit light loads. The shaft is forced into a hole made of softer material. The serrations are tapered for tapered fits.

Straight-sided Splines

These splines are often used for sliding members in the automotive industry.

Involute-Form Splines

These involute-form splines are used to transmit high loads. The splines can be parallel or helical.

Involute-Form Splines in Compound Pinions

We can make special involute splines by using the gear tooth proportions. A compound pinion is shown here made by cropping the smaller pinion teeth and internally splining the larger pinion.
