Non-Contact Measurement of Splined Shafts
The industrial revolution brought with it the requirement to transmit power from a central location to individual machines via shafts and belts. While this problem was initially solved with the introduction of single-tooth keys and keyways, the move away from chain drives and axles to gearboxes and driveshafts called for a more elegant solution – the spline assembly. Whether involute splines or serrated splines, this innovation now comes in a variety of forms that have a key characteristic in common – complexity that demands high accuracy metrology to ensure quality.
