Abstract
Disclosed is a stroboscopic method of determining the quality of meshing between respective teeth of two or more gears. By way of example, a method is disclosed by which a standard is established by directing an adjustable pulse rate light beam (L) from a stroboscopic light source (18) towards a region (R) generally encompassing the location of meshed engagement between respective teeth (6; 8) of a pair of gears (2, 4) rotating at a predetermined rpm that are selected on the basis that they possess degree of mesh engagement quality desired for such gear pairs. One of gears (2, 4) is rotated at the predetermined rpm by an adjustable drive means such as a motor (14) and the pulse rate of light beam (L) is synchronized with the predetermined gear rpm to provide a pattern of light refractance interference lines that can be recorded and used as a standard against which the light refractance interference pattern of other gear arrangements of the same type and at the same rpm and direction and light beam pulse rate can be compared to determine the quality of mesh engagement between the respective teeth thereof.
