Аннотация

This article village farm in the technique wide applicable roller bearings work activities and services the deadline extension important methods analysis does. In the article village farm of the technique to oneself typical heavy work conditions ( dust, humidity, high loads, impacts ) of bearings faster from work to the exit take arrival shown. Bearings service the deadline extension for applicable main methods, including right installation, quality lubrication from materials use, optimal lubrication interval to mark, to avoid contamination protection to do, to do too much outside of downloads prevent to receive and regularly technician service show such as issues in detail seeing is released. In the article village farm enterprises for practical recommendations given to them​ compliance to do through of the technique from work exit circumstances reduceand repair expenses optimizationpossible. Keywords:​ roller bearing, service term, village farm technique, lubrication, installation, technical serviceshow, work conditions, loading, pollution, work exit​ . Introduction. Village farm Uzbekistan economy important network is, its stable development modern, reliable and efficient from the technique to use directly Tractors, combines, seeders, cultivators and other​ ​ many village farm machines own in the composition moving of parts reliable performance provider many mechanisms and assemblies has. This of mechanisms important from the elements one was roller bearings rotating of parts stable performance to provide, friction reduce, loads distribution tasks will do. Village farm technique to oneself typical heavy exploitation conditions, including dust, mud, humidity, temperature sharp change and high mechanic downloads under the influence It works. Such an inconvenient factors roller bearings faster wear and tear, damage and, as a result, of the technique from work to the exit take arrival possible. The technique stop to remain agrotechnician of events own on time to be fulfilled negative impact shows, productivity reduces and the village farm of enterprises economic efficiency Therefore, the village​ farm in the technique applicable roller bearings service the deadline extend, their reliability promotion and dismissal exit circumstances reduce current problem is considered. Bearings far time during effective performance provide to the technique service show expenses optimization, technique from work exit time to reduce help gives. This article village farm in the technique wide applicable roller bearings service the deadline extension there is methods analysis to do The article is focused on bearings from work output main reasons seeing are issued and their prevent to take and service the deadline extension according to practical recommendations This is given. research results village farm to thetechnique service indicator professionals, engineers and farmers farm enterprises for useful to beis expected. Methodology. This in the article village farm in the technique applicable roller bearings service the deadline extension methods detection and analysis to do for practical-analytical method This http://www.internationaljournal.co.in/index.php/jasass 783 Volume 15Issue 06, June 2025 Impact factor: 2019: 4.679 2020: 5.015 2021: 5.436, 2022: 5.242, 2023: 6.995, 2024 7.75 was used. method within following stages doneincreased : 1. Performance conditions study : Uzbekistan different climatic operating conditions ( dry, hot, humid ) being done main village farm machinery ( tractors, combines, plows, seeders )​ bearings work conditions directly observed and analyzed was done. Observation during to bearings impact provider main factors, including hang​ level, humidity level, job temperature, load type (static, dynamic, percussion ), rotation speed and vibration level record arrived went. 2. From work came out bearings analysis To do : Village farm technique repair from workshops from work came out roller bearings samples to collect and visual and instrumental (microscopic) analysis, hardness measurement ( analysis ) to do done As a result of the analysis bearings injury types ( cracking, corrosion, erosion, fatigue, contact injuries ), injury causes and places determined. 3. Lubrication materials and technical service show practice Study : Village farm in enterprises bearings lubrication for in use lubrication of materials types, quality, lubrication interval and technical service show according to current instructions studied. Also, technical service show in theprocess mistakes and shortcomings determined. 4. Scientific literature and experts his/her opinion Study : Bearings exploitation, lubrication, damage diagnostics and service the deadline extension according to there is scientific literature, standards and guidelines ofexperts thoughts studied.
