Calculated Model of Wedge-Shaped Sliding Support Operating on Lubricating Material

Аннотация

In this work, the method of forming an exact automodel solution of a problem of hydrodynamic calculations of the wedge-shaped support (a ram and guide) working in the presence of lubricant and the melting of a guide taking into account the dependence of the viscosity of the lubricant on pressure has been given. Based on the equation of the movement of viscous incompressible liquid for a thin layer, an expression has been obtained for the speed of the dissipation of the energy analytical dependence for the profile of the melted guide surface taking into account the dependence of the viscosity of lubricant on pressure. In addition, the main performance data of the considered couple of friction have been defined. An assessment has been carried out of the effect of the parameter due to the melting of the guide and a parameter that characterizes the dependence of the viscosity of the lubricant on the pressure, load-bearing ability, and friction force.
