Diseño y construcción de un prototipo de molino tricilíndrico para la molienda de pintura al óleo : diseño y construcción del sistema de transmisión de un prototipo de molino tricilídrico para la molienda de pintura al óleo.

Abstract

A high-quality oil paint requires a machine capable of optimizing production without compromising product quality. In this project, a prototype of a three-cylinder milling machine is designed and build for grinding oil paint for the ""Óleos América"" company. This project focuses on the design and construction of the mill's power transmission system. A ¼ [hp] three-phase WEG motor with a nominal rotation of 1800 rpm is selected. After coupling to a gearbox, it delivers 90 rpm to the drive shaft. Mechanical power is transferred using spur gears made of 705 tempered steel. In total, four gears with a face width of 15 [mm] and 1.5 [mm] module are used: two with 22 teeth and two with 65 teeth. These gears are arranged so that a small gear is connected to a large one to achieve rotational speeds of 30.2, 90.8, and 267.1 rpm for the rollers. The transmission shafts, made of 304 stainless steel, form a single body with each of the rollers. Precision knobs are used on four supports to control the separation of the rollers. Results of this work enable the proper distribution of power to the mill rollers. This ensures efficient grinding of the oil and pigment mixture, which is necessary to obtain the production of quality paint for various applications.
