Help About Identifying a Spline

Help About Identifying a Spline

Help About Identifying a Spline

(OP)
I'm trying to identify the spline but i could not any standard about it.
I identified the modul, teeth , pressure angle but i need more information.

Mod. 1,0583
Z. 27
P.A. 30°



Can somebody help me to find more details.



Thanks.

RE: Help About Identifying a Spline

since this isn't an even standard module, there may be two cases,
it's a special module (Metric)
or it's a English version (English)
25.4/1.05883 = 23.98874 (24 DP)
Review both American or Metric specifications.
to verify the same tooth thickness, and major minor diameter.
I mostly work with American standards b92.1 splines.
search previous post for the Metric Specifications.

reverse engineering requires a CNC Checker.
if you have the correct data # Teeth , Module or DP , Then Pressure angle.
the Involute will be correct allowance for wear or Profile modification.
if the data is off, the involute will be grossly in error.

You might want to read this: https://www.geartechnology.com/issues/0994x/finney...
ANSI B92.1/BS 3550 both have that pitch.
Your measuring report does not show us enough information to identify the spline, because we can't see any of the diameters. But your question was not about identifying, so this is just a remark.

RE: Help About Identifying a Spline

As spigor says your report does not show enough information the Major Diameter and a pin measurement would help. I have run a couple of programs to give a guide to what it might be and my conclusion is that it is likely to be ANSI B9-1-1970 (revised 1993)Table 15 which is a flat root spline.

RE: Help About Identifying a Spline

remember Measurement over wires can not measure Max Effective size.
but it will measure actual Max Actual & Minimum actual tooth thickness.
measure the Major diameter and Minor diameter.
again to make sure you have the correct data, have an involute inspection run
if you have the correct data the involute will be correct.
this will nail it, if you have the correct data.
the object would be to make sure it will fit the mating part.
