Abstract
"ACABADORAS DE CONCRETO E RESPECTIVOS MéTODOS DE CONTRUçãO E DE OPERAçãO". Uma acabadora rotativa de dirigir por trás é configurada para ser 'dinamicamente equilibrada', de modo a se minimizarem as forças/torque que o operador deve suportar para controlar e guiar a acabadora. As características que são consideradas para este projeto incluem, mas sem limitação, atrito, torque do motor, centro de gravidade da máquina e posição de punho de guia. Em conseq³ência, resultaram um equilíbrio dinâmico e uma conseq³ente redução de força/torque, quando o centro de gravidade da máquina foi substancialmente deslocado em relação a um centro de gravidade típico de máquina. O equilíbrio dinâmico pode ser obtido, de forma mais prática, pela reversão da orientação do motor em relação ao conjunto de punho de guia, quando comparado com acabadoras rotativas de dirigir por trás tradicionais, e deslocando-se o motor tão longe quanto prático para a direita. Este deslocamento mostrou reduzir as forças operacionais e o torque que o operador deve suportar em pelo menos 50%, quando comparado com máquinas tradicionais.
