- Abstract
- The development and creation of high-performance machines for agricultural production is in many cases limited by the insufficient wear resistance of individual parts and assemblies. Russian scientists, engineers and technicians working on the problem of increasing the durability of machines have achieved significant results. However, theoretical conclusions and prerequisites for increasing durability and the method of calculating parts of agricultural machines for durability are not enough. The durability calculations of agricultural machine parts used in some cases during their design are imperfect. In addition, in most cases, there are no reasonable calculations of allowable wear that would ensure high quality machine operation, i.e. these calculations are not related to the tasks of preventive maintenance and operation of machines. A number of scientists have been studying the abrasive wear of working parts of soil-cultivating and seeding machines for decades, but this issue has not yet been finally resolved. Until now, there is no clear understanding of the essence of abrasive wear and the factors that determine it. Most of the work carried out on the study of abrasive wear of parts of working bodies of soil-cultivating machines is of a private nature. There are no works covering the study of the complex set of phenomena that occur during abrasive wear. At present, very little has been studied about the wear capacity of soils, there is no criterion that determines it, and there is no connection between the phenomena of wear of the working parts of soil-cultivating machines and the basic theoretical principles of agricultural mechanics. The study of the wear capacity of soils, as well as the determination of the magnitude of pressures that arise during the interaction of the working parts of agricultural machines with the soil, can be used when calculating the working parts of these machines for durability.
