Sensitivity of Optical Measuring System for the Determination of Optimal Reversible Two-Speed Planetary Gear Train for Machine Tool Gearboxes

The main goal of the study was to determine the sensitivity of optical measuring system for the determination of optimal reversible two-speed planetary gear train for machine tool gearboxes. The sensitivity could be determined by different experimental approaches but in this article adaptive neurofuzzy inference system (ANFIS) was used. This approach is useful to avoid complicated physical interactions during the process. In other words, ANFIS approach only needs input/output data samples in order to determine sensitivity values of the optimal measuring systems. In order to determine the model of multi-criteria optimization variables, objective functions and conditions should be determined. The subject of the paper is two-carrier, two-speed planetary gears with brakes on coupled shafts. Apart from the determination of the set of the Pareto optimal solutions, the method for choosing an optimal solution from this set is also included in the mathematical model. The procedure is illustrated by numerical example in which the optimal two-speed planetary gear train is selected, defined by design parameters. For the comparison purpose, coordinate measuring machine (CMM) was used also. Results showed that the CMM has the highest sensitivity during the process. The optical noncontact sensors were more resistant during machining process than CMM.
