The influence of jet links' parameters on the stress loading of tractor's power train sites

In the article are described the results of calculation researches of influence of ruggedness of fastening to aframe in cross-section and longitudinal planes of case parts of a power chain of a caterpillar, and also ruggedness of communication with aframe in the same planes of a combustion engine on dynamic stress loading of sites of a power train during movement with different speeds. Except the specified ruggedness of fastening, this dynamic loading depends on parameters of shifting jerks which take place in a power shafting owing to non-uniformity of action of the basic operational loadings - oscillations oftraction resistance, cross-section and axial vibrations of a framework of a tractor on a suspender, rewinds of a Caterpillar chain, non-uniformity of rotation of a shaft of the engine. Researches have shown that at the expense of steering of ruggedness of fastening to an engine bed and case parts of transmission it is possible to essentially lower dynamic stress loading of separate sites of transmission in movement modes when details of these sites are loaded as much as possible. The circuit solution is offered for realization in a fastening design to a frame of the case of transmission of caterpillars of VT family which will allow to lower stress loading of transmission details on certain speeds of movement.
