What is the difference between involute spline and triangular spline?

What is the difference between involute spline and triangular spline?In fact, the difference between them is obvious,SplineThe cross section is different, the specific description is as follows, for reference and understanding.

1. Involute spline:

The tooth profile is involute, and there is a radial component of force on the gear teeth when loaded, which can play a self-centering function, so that each tooth has a uniform load, high strength and long life.

The processing technology is the same as that of gears, the cutting tools are more economical, and higher accuracy and interchangeability are easy to obtain.It is used for connections with large loads, high centering accuracy requirements, and large dimensions.

2. Triangular spline:

The tooth profile of the inner spline is triangular, and the tooth profile of the outer spline is an involute with a pressure angle equal to 45°. It is easy to process, and the teeth are small and large, which facilitates the adjustment and assembly of the mechanism and minimizes the weakening of the shaft and hub.

It is mostly used for static connection of light load and small diameter, especially suitable for the connection of shaft and thin-walled parts.
