Investigation of parallel axis gear test rigs and selection criterias to design

Gears are used in different industries from machine and equipments manufacturing to automotive industry, from energy industry such as steam and hydraulic turbines, wind turbines to aeronautics such as helicopter and aero plane industries. There is an increasing demand for gears which work at high speeds and carry high loads, so there is more need for gear research and development activities on gear subject like wear, fatigue, transmission failures, failures based on vibration and noise. In this study, parallel axis gear test rigs have been investigated and selected to design.
