Abstract
This article presents an innovative method of diagnostics of rolling bearings used in the bearing nodes of motor vehicles, with the use of a prototype specialist stand. The tests were carried out based on a developed research plan, which included the impact of damage to the bearing and tyre of the vehicle, as well as the vehicle speed. Vibration accelerations were recorded in three measurement axes. Signal spectra were created based on the time courses of the vibration signals and were further analysed. The presented method is aimed at detecting excessive wear of rolling bearings in wheels from its early period.
Highlights
Extensive use of rolling bearings in operating means of transport necessitates the evaluation of their technical condition
The cost of the rolling bearing is small to the costs associated with their replacement and damage to other parts or the whole components whose correct operation is dependent on the condition of the bearings [3, 4, 7, 9, 10, 14, 17,18,19]
This article attempts to address the subject related to the impact of selected operating parameters on measures of technical condition of bearings built based on the analysis of vibration signals
Summary
Extensive use of rolling bearings in operating means of transport necessitates the evaluation of their technical condition. Given the above symptoms, rolling bearing diagnostics based on the analysis of vibration signals seems to be the most reasonable, due to its non-invasive character - no need to dismantle the bearing. Another advantage is its ability to detect wear at a relatively early stage [15]. This article attempts to address the subject related to the impact of selected operating parameters on measures of technical condition of bearings built based on the analysis of vibration signals.
