What is the formula for the internal minor diameter of involute spline?
What is the formula for the internal minor diameter of involute spline?
Term
| Term | 37.5 deg φD | |
|---|---|---|
| Major Diameter, External | (N + 1)/P | |
| Minor Diameter, Internal | (N – 0.8 )/ P | |
| Minor Dia. Ext. | 2.5/5 thru 12/ 24 pitch | (N – 1.3)/ P |
| 16/ 32 pitch and finer |
What is a standard spline?
Typical involute SAE/ANSI spline teeth are specifies as two numbers: a numerator that specifies the tooth thickness in diametral pitch (DP) and the second number that specified the tooth height in diametral pitch (DP). Thus an 8/16 spline has the tooth thickness of 8 DP and a tooth height (whole depth) of 16 DP.
What is standard screen spline size?
Screen Spline Diameter Chart

| .220 | 14/64 | 5.588 |
| .250 | 1/4 | 6.350 |
| Flat Spline | 3/8 | 9.525 |
What are the dimensions of an internal spline?
Where: c F Form Clearance D Pitch Diameter D Fe Form Diameter, External Spline D Fi Form Diameter, Internal Spline D i Minor Diameter, Internal Spline
What are the dimensions of flat root splines?
a) The external major diameter, unless chamfered or reduced, may interfere with the internal form diameter on flat root side fit splines. Internal splines made to the 1957 and 1960 standards had the same dimensions as shown for the major diameter fit splines in this standard.
How are pitch diameter and teeth related on spline?
A metric version of pitch known as metric module is showing up more frequently on spline data. This module is the same a the pitch except that it is a relationship between the pitch diameter expressed in millimeters to the number of teeth. Module = pitch diameter in mm’s / number of teeth
Can you use spline data for reference dimensions?
Spline Data and Reference Dimensions. Reference data on spline data ;should not used for engineering and manufacturing purposes. Pitch and pressure angle data will then not be subject to individual dimensional inspection.
