In this study, a design approach aimed at
increasing load-carrying capacity and system lifespan in wheel bearing units,
which are among the critical components of mechanical systems, has been
investigated. Although deep groove ball bearings, commonly used in conventional
wheel systems, provide adequate performance under radial loads, they may prove
insufficient in carrying the axial loads that arise particularly during turning
and maneuvering conditions. This situation can lead to premature wear, vibration,
and performance losses in the system. To address this problem, the existing
bearing system has been redesigned using 7204 series angular contact ball
bearings, which are capable of simultaneously carrying both radial and axial
loads. The design and modeling process was carried out in the SolidWorks
computer-aided design environment, and compliance of the system components with
international standards (ISO) was ensured through the SolidWorks Toolbox
library. The wheel hub and shaft geometry were optimized by taking into account
the contact angle, mounting arrangement, and geometric compatibility of the
bearings. Assembly checks performed on the 3D model revealed that the use of
angular contact ball bearings reduced axial clearances, increased rigidity, and
improved assembly accuracy. In conclusion, this study demonstrates that
theoretical bearing selection criteria can be successfully applied in a
computer-aided design environment, and shows that 7204 series angular contact
ball bearings offer a performance-enhancing solution for wheel bearing systems.
Furthermore, through the three-dimensional modeling approach, both the visual
and functional integrity of the system were examined in advance, enabling
design decisions to be made in a reliable manner.
