Recent advances in the maintenance and management of physical assets have become important tools to avoid losses and reduce costs in production. Without these advances, there would be many problems related as the reduction in the remaining useful life of industrial machinery, a decline in the quality of manufactured products, a risk to employee safety, increased demand for work and increased costs and expenses, which would affects the profitability of companies. With this in mind, a failure analysis of the main mechanical components of machines becomes essential to avoid unplanned shutdowns. In this sense, this work proposes the use of Failure Modes and Effects Analysis (FMEA) to analyzes reasons for failures, their causes and effects in a self-aligning roller bearing of a pulp and paper industry. The bearing is located on the head roll of a paper machine in the process of forming the sheet of paper. The failure to be analyzed is the bearing fracture of a bearing. This failure can be caused due to excessive bearing vibration or assembly error, since the occurrence found was overheating of the bearing. More causes were stratified for the occurrence of this failure, starting from the hypothesis that the root cause is the axial clearance of the bearing. Priorities and actions have also been established to prevent recurrence of failure and further breakdowns in critical mechanical components of the machine in question. |
