The results of the solution of the integral equations of motion numerical method presented in dimensionless form related to the relative inertia of the particles and the relaxation time of the particle. It is found that when the increase in the relative inertia of the particles, decreases the coefficient of turbulent diffusion of the dispersed phase compared to the ratio of the carrier medium. Increase from-wearing leads to an increase of the coefficient of turbulent diffusion of particles. It is shown that the calculation of the coefficient of vertical diffusion of dispersed impurities in watercourses must take into account not only the turbulence characteristics of the carrier medium, but also the relative inertia of the particles.

The outer shell is an important component influencing on the working capacity of roller one-way clutches. The analysis is carried out and recommendations about use of mathematical models for calculation of deformation of outer shell are made. It is established that at change of number of wedged rollers in a range from 3 to 7 there is a nonlinear decrease of value of a radial deformation, and in a range from 7 to 30 its increase.
