Study on Factors Having Influence Upon Efficiency of AC Motor Chain Drive Using Newly Developed Method and Procedure for Identification of Its Friction Losses

摘要

The purpose of this paper is to develop a new method, procedure, and measuring system for the identification of friction losses and mechanical characteristics of an asynchronous motor chain drive, as well as to apply them in the study of the impact of its design parameters and other operating factors on its performance. The proposed method allows monitoring the efficiency of a chain drive with a higher accuracy compared to existing methods since it does not require the use of strain gauges and, therefore, eliminates the need for their calibration and allows studying chain transmissions in dynamic operating modes in a wide range of rotational speeds and loads. The results obtained in the experimental part of this paper determine the factors that to a considerable degree affect the efficiency of a chain drive with a single-row sleeve-type chain, which indicates the applicability of the developed procedure and the measuring system for the control of its technical state under different operating conditions.
