Splines 150302j Flashcards
(13 cards)
Why are splines better than keyways
Integral part of the shaft
More surface area
No stress concentration
More contacts
Why are involute splines better than straight-sided splines
More torque
Self centering
What advantages do straight-sided splines have over involute splines
Easier to make and Design
No need for form cutters
What are the 4 SAE straight-sided spline series
4, 6, 10, 16 spline
What are the standard pressure angles for involute splines
30 degrees
37.5
45
How is the pitch of an involute spline expressed
4/8
4 diametral pitch
8 stub pitch
What is the most common way to mass-produce a spline
Generating
Hobbing or shaping
What other methods can be used
Milling with a form cutter
Milling with an endmill or plain Milling cutter
Broaching
American National spline pitches are given as a combination number. Select the correct format
Stub pitch/diametral pitch
Addendum/dedendum
Diametral pitch/stub pitch
Addendum/working depth
Diametral pitch/stub pitch
The class of fit for an American National involute spline series includes
Side fit and major diameter fit
the most common method to manufacture an SAE straight-sided external spline in a jobber shop would be
Straddle Milling for external
The most efficient method to produce an internal involute spline would be
Broaching
How is a 10/20 involute spline different from a 10 DP gear
Tooth is shorter
