Verificação e análise de parâmetros na remotorização de esmerilhadora de perfis

Abstract

Due to recurring failure modes in the maintenance of track machines, and also the increasing commitment of companies to invest in the continuous improvement of their products and processes in the requirement for the use of reliability techniques, this paper deals with the study and structuring of Failure Mode and Effects Analysis (FMEA) in assembly and manufacturing processes of mechanical coupling in the adaptation set of an internal combustion engine, with a view to a proposal for maintenance equipment repowering the railway tracks. The proposal is also seen as a way to improve the reliability-centered maintenance plans of an outsourced company of a large mining company, due to recurring failure modes, generating delays and rework in the maintenance flow. In this way, steps were structured in order to apply the tool in the best way possible, within the research problem, each coupling component was designed and defined, as well as function and specifications, defined the concepts of failure modes, causes and effects in indications of recurrent failures, in addition to structuring analyzes against indicators. The work resulted in the elaboration of planned correction and detection actions that significantly favor the realization of the manufacturing and assembly processes of the coupling, basing guidelines on carrying out a production process with higher quality, reliability and security, decreasing the probability of failure.
