Grynenko O. Increase quality the driving axle of the agricultural all-purpose tractor

The process of loading and change life time of the all-purpose agricultural tractors driving axles during implementation of agricultural works is a research object. An improvement of quality of the all-purpose agricultural tractors driving axles by perfection of methods of the design and operation is a research purpose. The methods of mathematical design are used in theoretical part. The method of strain measurement and mathematical statistics are used in experimental part. Practical value of the got results. The mathematical model of the agricultural tractor operation which allows on the stage of design to choose optimum track of tractor define necessary engine power and estimate the parameters of the life time transmission of the tractor is design and soft realized. The recommendation on the increase of quality of the all-purpose agricultural tractors driving axle are design and accepted to introduction on the XTZ. Two programs of the tests and six technical reports were accepted by results work on XTZ. Scientific novelty of the got results: - dependence of distributing of refuses of elements the transmission of tractor is first set on their location; - parameters which most strongly influence on the asymmetric loading of tractor are first exposed; - methodology of calculation of optimum track of tractor is first developed depending on descriptions of the added agricultural instrument and methodology of calculation of the wheeled reducing gears under act of the asymmetric loading; - principal reason of loss of capacity of one elements of transmission a tractor is first set at a satisfactory capacity other. Purview: design and exploitation of tractors.
