Measurement of Gear Accuracy

This chapter introduces various methods commonly employed to measure the accuracy of gears. It commences with an introduction to gear accuracy, need for accuracy measurement, introduces various accuracy parameters as appropriate to gears, and briefly introduces the measurement techniques. This is then followed by an introduction and discussion of analytical and functional inspection and measurements of gear accuracy. The aim of this chapter is to introduce the basic concepts of gear accuracy and measurement linked to the causes of inaccuracies and how these may be prevented. The scope of this chapter excludes gear-health monitoring including noise, vibration analysis, etc.
