Abstract

The positioning error value at any point of contact in a gear set is known as the transmission error. Changes in transmission error during the engagement cycle have been identified as the source of vibration in an operating system. To predict the extent of these vibrations for a given application it is necessary to model the various effects which define contact conditions. It is possible to acquire data to model some effects by direct measurement. Gear tooth deformation due to a torque load has been difficult to quantify under dynamic conditions since the harsh operating environment excludes the mounting of delicate equipment used in data acquisition such as strain gauges. Also, a substantial
