Comprobación del material elaborado de residuo de cuero-resina de poliuretano como disipador de vibraciones

Abstract

Following the investigative progress we made in 2019, where we characterized the mechanical properties of a compound made of polyurethane resin and leather processing waste, which will be named Cuerol (Morales & Garcia, 2019), the need arose to find a practical application in the field of mechanical engineering. Based on the results obtained: an elasticity modulus of 1.4785 MPa and tensile strength of 3.1 MPa, it was determined that the material could have an application as a vibration isolator, since these elements are made of rubber and share very similar values: rubber with an elasticity modulus of 1.4 MPa (erika dureza, 2023). In industry, the problems generated by the presence of vibrations in machinery, due to the environment, place of fixation, imbalance, or its coupling system with other machines presenting unusual vibrations, generate premature damage in wear elements such as bushings and bearings, among others, even leading to cracks and breaks in fixation bolts. In relation to the above, in the maintenance area, one of the determining factors for the good performance of a machine corresponds to predictive maintenance techniques. Vibration analysis is one of the most widely used strategies to monitor and predict anomalies such as wear, misalignment, imbalance, and damage in bearings. These procedures are vital for the correct functioning of internal elements, as continuous operation under high vibration conditions can affect the useful life of internal components such as bearings and gears, among others. Based on previous research (Morales & Garcia, 2019), and knowing that the elasticity modulus of Cuerol is similar to the base material from which vibration isolators are made, the present investigation seeks to determine the feasibility of Cuerol as a vibration damper through vibration analysis of a one-horsepower motor under normal and unbalanced operating conditions
