The development of new aggregates of mobile machine aims at the reduction of production and operational costs and, at the same time, at the increase of transmitted power when a sufficient reliability is provided. Simultaneously, the real operational safety concerning maximum permissible stress is also rescued. This results in necessity of further more exact methods of design and strength control of aggregate elements. The use of vibration data from rotating machinery to determine machine health has a long history. A practical example of gearbox vibration frequency analysis is presented, which demonstrates the use of high-resolution frequency controls using zoom FFT for diagnostic purposes. It is intended to show how to get and interpret good results from controls, with particular reference to points, which arise in gearbox applications.
