TEST PROCEDURE FOR CHAIN COUPLINGS

The purpose of testing chain couplings is to substantiate and confirm the validity of assumptions and premises adopted in theoretical studies, to obtain additional data on the characteristics of existing couplings and new results on the couplings of the proposed structures. To obtain reliable information about the product, various tests must be carried out, they are static, dynamic, bench resource, industrial resource. Testing of couplings, like any product, must be performed to ensure high reliability of the results obtained, as well as to reduce the time required for preparation and testing. Simulation of real-world operating conditions with maximum completeness and accuracy, i.e. a reasonable choice of test modes, helps to increase the reliability of test results. Therefore, optimization of bench operating modes is provided during planning. Static characteristics of the chain couplings of main structures used in mechanical engineering in accordance with the proposed methods are found out. The proposed method of experimental determination of the efficiency of compensating couplings makes it possible to obtain the necessary data for the designer, which will help at the design stage of the machine drive to select the type of coupling and normalize the accuracy of the installation of the units connected by it. The method of bench and industrial testing of chain couplings is described.
