Application of Technical FMECA (Failure Mode and Effect Analysis) in Roller Bearings for Freight Car

摘要

The railway is one of the sectors of greatest growth in Brazil. Today the market demands precision for the arrival time of their products, besides increasing the reliability with which the load is carried. There are the environmental concerns, where the impacts of the operation of transport should be minimized managed by minimum standards focused on governmental guidelines. This requires the railway companies a pro-active in trying to improve the planning through techniques and technologies more current. One of the key to improving the planning rail, as it pertains to the operation of its assets, is the use of tools for managing and disposing of failures. The bearing is one of the items at significant cost and difficult to identify failures. Therefore, this study proposes the use of the tool FMECA (Failure Mode and Effect Analysis) for analysis of bearings in rail wagons, one of the critical components of active rail freight. With the results we can conclude that the FMECA can be used for a study of data for the study of failure of this component, and can be applied to other equipment, trying to improve the process of maintenance, to ensure that will meet the expectations of the customer.
