Abstract

This paper describes the traditional methods used for checking worm gears, using contact marking techniques and discusses a new method for the analytical measurement of worm gears which uses a CNC gear inspection machine at the UK National Gear Metrology laboratory. Some of the development and validation problems are discussed and example measurement results are given. 1.0 Introduction and Background Equipment, standards and procedures for the measuring of involute spur and helical gears have been available for many years. During this time, manufacturers of involute worm gears, although an important part of the transmission business, have not had this luxury because the geometry of involute worm gears is far more complex than involute spur and helical gears. A typical worm gear pair is shown in F
