TRIBOMECHANICAL SYSTEMS IN MECHANICAL POWER TRANSMITTERS

Abstract

In this paper, the detailed analysis of tribomechanical systems for transmission of power and movement in mechanical transmitters is presented. The basic tribological characteristics of tribomechanical systems are friction and wear that are the main causes of systems structures alterations, energy loss and losses of material. As natural processes, the friction and wear, depend on a large number of different factors: systems structures, exploitative conditions (speed and load), mechanical chemical properties of materials, characteristic of lubrication, aggressiveness of environment, temperature, topography of contact surfaces, mechanical processing (pre-processing and final processing), etc. On the basis of the relevant information, the classification of basic tribomechanical systems is done. By the analysis of specific tribomechanical systems in certain mechanical transmitters, the identification of common wear modes, theirs causes and recommendations for avoidance are done.
