Abstract

The serviceability and durability of tillage attachments is largely determined by compliance with the requirements for the organization of care and supervision of the condition of the bearing catches of these units during their operation in abrasive-aggressive environments. One of the solutions to restore the operability of the friction unit is the improvement of the structure using inserts made of modified wood. A comparative structural, technological and operational analysis of the working capacity of two types of hubs of the ADU-6 AKD tillage unit was carried out: the basic one – with roller radial thrust rolling bearings in the friction unit, and the upgraded one – with sliding bearings made of modified end-press deformation wood. As a research task, the authors determined the assessment of the physical condition of the friction units to meet the required level of reliability and durability during mechanical tillage. Based on the results of field tests, it was found that the resource of the upgraded hub is 5.1 times greater than the base one. It is shown that the proposed assembly technically simplifies the design of the hub, reduces maintenance costs during operation, has a minimum coefficient of friction and does not require additional supply of lubricant. The economic efficiency of the prospective introduction of modernized hubs into the friction units of combined tillage aggregates of agricultural organizations of the Gomel region is calculated.
