Din5480 or 5482??

Din5480 or 5482??

Din5480 or 5482??

(OP)
Hi Chaps - I wonder if you could sort something out for me?

I am looking to order a splined shft that will have a fit that doesn't give too much lateral movement because at the moment the current shaft slops around too much and I want a tighter fit.....

The current internal spline data is as follows...

Teeth - 16
Dia pitch - 20/30
Pressure angle - 30 degrees
Base Dia - .6928"
Pitch Dia - .8000
Major Dia - .895/.885
Minor Dia - .738/.733
Form dia - .873

The current shaft I have is like this....

Pitch Dia - 30.320
Major Dia - .866/.862
Max Circ tooth thk - .073
.908min over .086dia pins


My question is...to get a shaft with a decent fit what will be the resultant size of the spline and what Din standard will it conform to?

In fact, what is the difference between Din 5480 and 5482

Thanks for your help!

RE: Din5480 or 5482??

The difference between them that I am aware off is that DIN 5482 has been withdrawn.

Ahh Right..at least I can have a bash at 5840 now then!

Cheers!

RE: Din5480 or 5482??

No matter which spline standard; if you are attempting to control the fit, you'll have to specify a tolerance based on the particular standard that you're using.
If you're using off the shelf items; tolerances which yield an 'ease of assembly' type fit is what is generally called for.

Hi Ron, thanks for the reply - these will be bespoke shafts and drives that are not off the shelf and conform to which ever standard is applicable :)

RE: Din5480 or 5482??

While the 5482 standard has been withdrawn; it's still commonly used, particularly in the hydraulics industry.
The pitches, number of teeth and addendum corrections are specifically chosen so that major & minor diameters are better suited to the range of bearings that may be available.
If you're going to look at using it, make sure your gear shop has tooling as the tooling, while metric, is not the same as for 5480.
