How are splines measured?
The tooth thicknesses and space widths of spline teeth are specified as both actual and effective. Actual tooth thicknesses and space widths are those for an individual spline tooth and are typically measured by over- or between-pin measurements. This is usually measured by go/no-go spline gages.
What is a involute spline?
Involute splines feature short and equally spaced teeth that allow for greater strength with more centered stress distribution.
How do you create an involute spline?
Design involute splines
- On the ribbon, click Design tab Power Transmission panel Involute Splines .
- On the Design tab: Click the arrow next to the Splines Type edit field to select the spline. Enter the spline dimensions. Specify the position of a shaft groove.
- Select OK.
What is form diameter of spline?
One of the most frequently neglected areas of gear design is the determination of “form diameter’: Form diameter is that diameter which specifies the transition point between the usable involute profile and the fillet of the tooth.
What is the most common screen spline size?
18×14, 20×20 fiberglass are most typical and Tuff Screen & Tuff Screen No-See-Um are also used and will work nicely with Flat Spline. Round Spline is most typical across the USA.
How are external splines made?
The splines are cut into the shaft by a process called straddle milling. The indexing fixture holds the shaft of the spline steady while a groove is cut by the rotating milling cutters along its length. Depending on the depth of the spline, multiple passes along the same groove may be needed.
How are splines designed?
The current practice for designing splines to carry a torque is to use involute splines with no helix angle or taper on the external tooth. In preliminary design, all teeth of the spline are assumed to carry an equal amount of load.
Does spline come in different sizes?

How to select an involute spline based on shaft Dia?
obtain the desired fit. The very simplest method of initially selecting of involute spline based on a shaft dia is to arrive at an initial Pitch circle dia (D) and a module (m). eg. a spline for a 50mm OD spline with say a module of 2mm would have a PCD (D) of 50 – 2 = 48mm. The number of teeth = D/m and as an whole number of
What is the difference between an external spline and an involute spline?
It is emphasised that the splines identified are side fit with the centering based on the sides of the splines Involute splines are the predominant form bacause they are stronger than straight sided splines and are easier to cut and the fit. The external spline can be formed either by hobbing or by a gear shaper.
What is the 30′ spline standard?
This standard has been prepared to rationalize the production and to facilitate interchangeability of exter- nal and internal splines. 0.4 This standard deals with involute sided splines of 30’ pressure angle for general engineeering ‘purposes.
What are the dimensions of an involute gear?
The following are equations and engineering design calculator to determine critical design dimensions and features for an involute gear. Diametral Pitch Teeth/in. Stndard sizes: 2.5, 3, 4, 5, 6, 8, 10, 12, 16, 20, 24, 32, 40, 48
