Trapozoidal Shaft Spline

[rothers]

We have some old rolling mill work rolls with trapezoidal form splined ends, the spline is approx 63 mm OD with 19 teeth. The rolls would have been originally made in Sweden about 50 years ago. All drawings for these rolls are long lost, we are trying to recreate.

Anyone know of a specification for this form of spline ?

We have the standards on straight splines (BS 5686, ISO 14, DIN 5464 etc) and involute splines (BS ISO 4156, DIN 5482 etc) but can't find anything on trapezoidal splines. (sometimes known as "plain" splines back in the day).

Machinery's Handbook in the USA is used by many orgainzations a as "standard" for these type of issues.

Thanks mkcski, Machinery's Handbook was one of the first places we looked. Unfortunately our copy, 26th edition, doesn't have anything on splines of this form.

Your welcome. Guess it is a ISO standard. Good luck.

You may have better luck searching for "serration" splines. DIN 5481 comes to mind.
