Parameters of apparatus equipped with local chamber for sluggish rust-preventing grease heating are substantiated. Mobile device for heating and application of sluggish greases on parts of agricultural machines was developed.
For development of transport infrastructure of rural territories, it seems necessary to develop a utilitarian all-terrain passenger and commercial light vehicle named conventionally “Vozhak”. Variant of its creative look is proposed, some specifications are given.
The task of perfection is to diminish load on the tractor and decrease cultivation blade wear, which will result in cost reduction of operation and repair of the aggregate. The technical result shows that share tractive resistance is diminished due to change in design.
Theoretical bases of engineering of two-stage fuel cleaning system in diesel machines fuel system are considered in two variants, namely combination of depth filtering elements and combination of depth and paper filtering elements.
Gear shift process by using a speed synchronizer in car and tractor gear boxes has been considered. The calculation method of slipping work and synchronization time for loading conditions of speed synchronizer, taking into account active drive torque from declutched frictional clutch, are proposed.
Wear pattern on the working surfaces of concrete mixer blades can be explained mainly by change of mix pressure on different points of working edge. The rotating blade angled to the rotation plane moves the mix both to direction of moving and along the concrete mixer axe. When high abrasive mixes of different fraction composition are prepared, wear of the working surfaces on thickness results in deflection, deformation and destruction of the blade.
The conceptual issues of V.N. Boltinskiy scientific heritage are stated, his contribution to progress of tractor industry and agricultural mechanization as well as his advances in training of engineering skills for agriculture are highlighted.
Results of comparative evaluation of movers performance indicators of vehicles exploited on weak soils are given, as well as production of low pressure tires as of from 1991 to 2013 are reviewed.
Vertical oscillations of tractor Т-150К during operation on sandy soddy-podzolic soil prepared to sowing were investigated. As result of calculations carried out using experimental data on viscoelastic soil properties, the influence of a tractor velocity on appearance of mutually independent oscillations of its axes was shown.
Actual systems of maintenance and repair in animal husbandry were analyzed, their advantages and disadvantages were revealed. Problems of perfection of economic relations between machinery manufacturers, commodity producers and technical service organizations are considered.
The actual status of machine and tractor fleet in the Republic of Armenia is described, statistics are given, and its development prospects are outlined.
The method of minimizing of working organs specific action on soil structure was proposed. Its advantages are visibility, possibility to include practically all constructive parameters of tillage tools into optimization model, direct target function control.
