Implementación de tres métodos para montaje y desmontaje de rodamientos en el laboratorio de mantenimiento correctivo de la Facultad de Mecánica

Abstract

During the process of assembling or disassembling a bearing, occasionally, damage is caused to the components of the machines and elements because of the application of inappropriate tools or assembly and disassembly methods that shorten the useful life of the bearing. Therefore, the objective of this technical project was to implement three application methods for the bearing assembly and disassembly module in the Corrective Maintenance Laboratory of the Faculty of Mechanics. A documentary investigation of the methods, equipment, and tools existing in the industry was carried out to develop installations of rotating elements with conical and cylindrical seats. Continuously with the research process, it was possible to conduct a comparison analysis between the relevant methodologies, thus determining the most effective one. In addition, mechanical and hydraulic tools were implemented based on a Failure Mode and Effects Analysis, allowing the interference fit, axial stall force and other essential parameters of the bearing's nominal life to achieve greater precision. Methods were selected using SKF oil injection, SKF Drive-up bearing drilling, and a mechanical process of rollers arranged back-to-back, giving access to special instruments to carry out the installations quickly, safely, and efficiently. It included the development of laboratory guides with step-by-step processes of each methodology using hydraulic and mechanical tools for didactic learning, concluding with work demonstrating the production methods' efficiency and importance in the bearing's proper life cycle.
