Abstract
At present time, in control systems, an electromechanical drive, which includes a reduction gear, is widely used. To ensure the quality of the output movement of the drive, it is not enough synthesize it according to the criteria of performance and accuracy. With increasing requirements for drives, the need arose for such an indicator of the quality of dynamics as smoothness [1], which is mainly influenced by the quality of the mechanical transmission production. The article provides an example of modeling a reduction gear taking into account multi-massage, the number of teeth, geometric errors of tooth-engagement, imbalance of the engine rotor. The spectrum of speed fluctuations of the output link is obtained, which characterizes the smoothness of the reduction gear operation. A conclusion is made about the prospect of using a model approach to diagnose the smooth operation of reduction gears.
