SYSTEM APPROACH TO ASSESSMENT OF THERMAL STRESS OF UNITS OF TRANSMISSIONS
Journal Title: Applied Engineering Letters - Year 2017, Vol 2, Issue 2
Abstract
In the article the application of system approach to the study of thermal stress of units of transmissions of transport and technological machines on the example of cardan joints is considered. The authors carried out the analysis of parameters of diagnosing of cardan joints for the purpose of assessment of their technical condition, in particular, assessment methods on bearing clearance in bearing mount assemblies and in vibration parameters. On the other hand, in the transport equipment diagnosing methods on temperature condition of the work of a unit are widely known. For justification of the practical application of system approach to the solution of problems of preliminary treatment of cardan joints and increase in their reliability the consideration of a unit at three hierarchical levels is necessary: the first is defined by workflows in a bearing mount assembly, the second – directly in the cardan joint, and the third – by workflows of the cardan joint as a part of the drive line. Adaptation of system approach in studying of temperature condition of cardan joints allows to prove the modes of increase in reliability of cardan joints by optimization of their thermal conditions.
