Constructions of motor and tractor differentials of high friction developed on the base of gears with intermediate rolling elements were examined. Results of differentials computer modeling are given.
Integrated approach to the problem of reliability insurance of system parts of an industrial tractor equipped with semirigid suspension and used in bulldozer and ripper aggregate is demonstrated. Series of constructor and technological actions aimed at system part longevity enhancement is suggested.
Dependence of limiting wear and parts service life on compression ratio and crankshaft rotation rate was determined on the base of wearing physics regularities and empirical data.
Results of investigation of tubers rolling on a free inclined plane of elevator canvas are presented. Procedure of determination of tubers free lifting and grinding length is given.
Operation of plane hexagonal working organ used on a disk hoeing plough for the cultivation of wind erosional soil was examined. Important regularities were revealed and described, and criterion of quality assessment of weeds undercutting depending on angle, cultivation depth and distance between disks on shaft was presented.
A mechanism was examined allowing to restrict the angular velocity of slipping wheel by means of its deceleration with specialized rollers driven by pneumatic brakes’ rear circuit.
Gasodynamic model of turbocompressor bearing unit channel with fuse lubricating system was examined. It permits to determine oil consumption in aggregate operation modes diapason.
Results of tractive and coupling parameters comparison of ordinary multilayer tires, thin-layer ones and tires-covers are given. An integrative parameter was suggested as quality estimation criterion for tires of low pressure, namely the efficiency coefficient of moving system.
