ansi spline call out

ansi spline call out

ansi spline call out

(OP)

I want to specify an internal spline correctly
I am using ansi B92.1 (from machinery's handbook, 28 ed)

the specification is:
FLAT ROOT SIDE FIT
CLASS 5
PITCH 32/64
PRESSURE ANGLE 30 DEG
BASE DIAMETER 0.8931 REF
PITCH DIAMETER 1.0313 REF
MAJOR DIAMETER 1.0734
FORM DIAMETER 1.0665
MINOR DIAMETER 1.000

CIRCULAR TOOTH THICKNESS
MAX ACTUAL 0.0519
MIN EFFECTIVE 0.0491

But a do not know what are the tolerances to use for major, minor and form diameter.

Machinery's handbook mentions:
Major diameter  x.xxx  MAX
form diameter   x.xxx
Minor diameter  x.xxx/x.xxx

how I get these values ?? ,
1) What is the maximum value for major diameter ??
2) Form diameter, is this value the nominal that I obtained ??
3) how I get the min/max value for minor diameter? I just have the nominal value.

Also, I am defining the male spline for this, so I need  the considerations for male spline tolerances,

I really appreciate your help, i have not found information about it.

thanks

Javier

thanks for your response.

that link send me to the ansi 92.1 1996, and it mentions this is an addition of the ansi 92.1,   does this ansi 92.1 1996 includes all the information of ansi the 92.1 1970 ??

I mean, Does this ansi 92.1 1996 include all the information for spline calculation ??

thanks for your help
