Coefficient of a Rolling Motion Bearing Drive

AbstractOn the basis of the Darcy's equations which define the lubrication flow in porous layers, and the Reynolds's modified equation, we solve the problem of an unsteady movement of viscous incompressible lubrication in the clearance of a porous damper. The peculiarity of this solution is a simultaneous account of dependence of lubrication viscosity and permeability of porous barrel.As a result, we have found the field of pressure in a porous and lubricant layer, analytical dependences for forces in the oily film as well as the equations describing non-stationary and stationary movement of the shaft center have been obtained. Besides, the module of unbalance transmitted force and also stationary and non-stationary drive factors have been established. It is proved, that taking into consideration a simultaneous account of dependence of the lubrication viscosity and permeability of the porous barrel, the damper works more steadily.The received specified analytical models have allowed establishing of the influence of some additional factors, and also making the comparative analysis of newly received results and already available ones. It has confirmed the great connection of a new model with a real practice
