The machine-tractor fleet of enterprises is an important link in the production of products of various branches of industry in Ukraine. The timely performance of transport, agricultural, road construction and other works, and ultimately the cost of products or services, largely depend on its effective work.
Rolling bearings are one of the most common technical devices used in machines. They largely determine the reliability and performance of devices.
The resource of the tractor chassis is mainly determined by the resource of the rolling bearings. Defects in the manufacture and operation of bearings affect the vibration signal in different ways and have different diagnostic signs. This makes it possible to identify defects at the stage of their occurrence and predict further development.
In this work, the method of vibrational non-destructive testing is considered when diagnosing the bearing assemblies of the hubs of steered axles of wheeled tractors of traction class 1.4. The mathematical model developed by the authors for diagnosing the bearing units of the hubs of steered axles of traction class 1.4 wheeled tractors is aimed at determining the technical condition of the rolling bearings and allows predicting their possible service life. The developed mathematical model allows you to determine the clearances in the bearings, vibration frequencies and the average value of deformation caused by the load on the bearing depending on the frequency of rotation of the separator and the inner ring of the bearing, the initial contact angle of the rollers in the bearing, the radius of the seat of the roller, the inner diameter of the bearing, the radius of curvature of the bearing. An equation was created to determine the unbalance of the hub of the steered axles and the seating clearance of the bearings.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
