Resumen
En el presente trabajo de diploma se realiza un estudio sobre las fallas en los rodamientos de la máquina para la fabricación de bloques de hormigón, VIBRACOM. La máquina usa rodamientos 11206E, del catálogo MRC, que sirven de apoyo a dos excéntricas que al girar producen las vibraciones necesarias para compactar el hormigón. Estos rodamientos operan a 2563 rpm soportando las reacciones en los apoyos debido a la fuerza de inercia (generada por el giro de las excéntricas), bajo estas condiciones la vida nominal de estos rodamientos es de 102 h, por lo se selecciona una unidad UC PG 206 D1 donde se inserta el rodamiento UC 206 D1 del fabricante NTN, recomendado para soportar las vibraciones y con aproximadamente el doble de la vida útil que el rodamiento
anterior.
Presently diploma work is carried out a study on the flaws in the bearing of the machine for the production of concrete blocks, VIBRACOM. The machine uses bearing 11206E, of the catalogue MRC that serve from support to two eccentrics that produce the necessary vibrations for compact the concrete when rotating. These bearing operates to 2563 rpm supporting the reactions in the supports due to the force of inertia (generated by the turn of the eccentrics), I lower these conditions the nominal life of these bearing it is of 102 h, for it is selected it an unit UC PG 206 D1 where the bearing UC 206 D1 of the manufacturing NTN is inserted, recommended to support the vibrations and with approximately double the useful life that the previous bearing.
