Implementación de un análisis causa raíz para el eje y cojiente del sistema de transmisión de potencia de las aspas del radiador, para el motor a gas Caterpillar 3408 y 3412.

Abstract

This work is oriented to analyze and evaluate the fracture of the shaft and the failure of the bearings of the power transmission system of the blades in the Caterpillar 3408 and 3412 engines, by means of the review of the failure history, the possible causes of the problem are identified. problem and through engineering protocols for the design of machine elements, the optimal solution is found to eliminate this recurrent failure of the system in charge of transmitting rotation to the fan blades of the cooling system of the rotating equipment belonging to the oil company PERENCO COLOMBIA LIMITED. The proper selection and application of the design, assembly and maintenance protocols is linked to the correct determination of the operational requirements and is supported by the theoretical concepts of the SHIGLEY mechanical engineering design book and the SKF bearings manual. Its validation process is carried out through system simulation in SOLIDWORKS SIMULATION. The evidence of the behavior of unexpected failures is supported by the information provided by the company's electromechanical maintenance technicians, operators and instrumentalists in their maintenance reports where the possible causes of failure are identified according to their experience in order to eliminate the problem at the root. uncertainty in estimating the useful life of these machine elements. The solution of the problem will avoid unexpected stoppages of the equipment, eliminating bottlenecks in the production of hydrocarbons and reducing maintenance costs.
