For the gears installed in machines and equipment, the alignment errors of the gear shaft due to the manufacturing of the gear box, the assembling of the gears, and the elastic deformation and backlash of the unit are usually unknown. The exact state of manufacturing errors of gears is also often unknown. This research proposes a new method to estimate the state of vibration of gears at arbitrary operating conditions from the data of vibrational acceleration measured at some definite reference operating condition when the manufacturing and alignment errors of gears are unknown. The paper explains the proposed method of estimation for the rotational vibration of gears with unknown accuracy and examines the validity of this method by the comparison between the estimated value and value of computer-simulation, and by the comparison with experimental results as well. It is confirmed that the state of vibration of gears with unknown manufacturing and alignment errors can be estimated by this method, if very high accuracy of estimation is not demanded.
