Surface roughness measurement of shaft parts of gearbox MQ100 using scattered light method
Horák, Josef ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
This thesis primary deals with the possible use of measuring the surface texture of gearbox MQ100 shaft parts in serial production by the scattered light method. The introduction briefly describes the company ŠKODA AUTO a.s., as well as gearbox MQ100. The paper continues by describing the process of manufacturing shaft parts, focusing on grinding, no. 130 for pinions and no. 135 for drive shafts, which is the last process of manufacturing shaft surfaces. The next part of the thesis describes the quality of ground surfaces in gearbox MQ100 shaft parts for the control period, followed by the dependency evaluation of parameter Aq, concerning the surface-structure optical measurement, on parameter Rz. After the dependency has been determined, the thesis delineates verification tests, and proposes a tolerance value for parameter Aq when taking the measurements by the diffused light method. In addition, a modification of the OptoSurf measuring device is suggested as well as the proposal of issuing a test certificate in order to determine the final tolerance value of parameter Aq.
