Methods of analytical calculation of resonance conditions of the gearings stipulated by two major factors - periodic change of rigidity of teeth on a phase of engagement and an impact teeth input in engagement in connection with inaccuracy of manufacture and mounting of gears, and also an elastic strain of teeth under loading are considered. Researches were carried out on the dynamic model considering only torsional oscillations of gears. Influence of damping on the resonance phenomena in gearings is studied.

In paper the problem of improvement of quality of manufacturing and the control of gear pairs planetary (epicyclic) gear drives is observed. It is solved by the introduction of tooth structure crowning. It allows to increase acceptable value of the angle of a mutual inclination of shafts in 2.8 times.

Statements from works dedicated to computation of mobile machines in variable operational environment and determination of vehicle load modes and lives of its units regarding the concepts concerning loading modes and their use for comparative estimations of life are developed. The problem of an estimation of units and aggregates lives in case of the absence of data for detailed life computation is considered. It is suggested that the life estimation should be produced by computing the extent of damage at characteristic points of mechanical system of the investigated machine and comparison of results with similarly received data from machinesanalogues. The technique is demonstrated by example of the life estimation of transmission ZF 6S850 under its use in vehicles MAZ-447131, DAF FAN LF55 21 tLHD and MAN TGL 8.180 7.5 Tonne 4x2 BB Tipper.
