Approaches to Measure Spline Shaft Diameter.
How to measure splines What and how best to measure them on the CMM depends on a lot of variables. How to properly measure the size of a splined or double D style steering shaft and count the amount of splines to ensure you receive the proper universal joi See full list on engineeringproductdesign. Then once the minor dia is good, I use disc mics to get my spline tooth thickness. The process of measuring the diameter of a spline shaft involves several methods. Approaches to Measure Spline Shaft Diameter. Jul 29, 2009 · A common spline has straight sides -- there are no involute curves involved. Method 1: Using Calipers. May 16, 2011 · Depending on the spline, I either measure over pins using an OD mic, or for something like a 6 key, ill use an OD mic if possible or calipers with these hoochie jiggers that attach to the jaws to measure the minor dia. com Apr 19, 2022 · Spline tolerances are usually based on go/no-go gages and tooth thickness measurement of one type or another. Details surrounding these methods will be elaborated in the following sections. It’s also not a straight sided spline as the pictures look like those keys are tapered. Calipers are the most common tool used to measure the diameter of the spline shaft. If you're talking about an automotive involute spline, they almost always use a stub form, typically 12/24 DP, or 16/32DP. What characteristics are you required to measure on the spline gages with your CMM? Are they involute splines? Are they normal spur splines or helical? You can tell by the shape of the root diameter and the fact that it has those grooves in the corners of the root. Involute splines are almost always 30° pressure angle. The numerator defines the diametral pitch, and the denominator is the stub pitch. Method 2: Using Micrometers. Those grooves are produced from a specific 8-spline cutter that has ears as it is more than likely minor diameter fit with the mate. zgplabzoplcmnxdkabzwjtnsyrfeeeltwosdtwvzwprlstdyvcixqx
