Abstract

"CONJUNTO DE DESGASTE PARA A ARESTA DE ESCAVAçãO DE UMA ESCAVADEIRA". A presente invenção refere-se a um conjunto de desgaste, que para ligar elementos de desgaste a uma borda de uma escavadeira, inclui um elemento de desgaste, uma saliência e uma trava. A borda inclui uma face interna, uma face externa, uma aresta de escavação e uma série de furos vazados, espaçados, para trás da aresta de escavação. As saliências são, cada uma, fixadas a uma face da borda em uma posição para trás dos furos vazados. Os elementos de desgaste, cada um, inclui fendas para acomodar a saliência adjacente a suas extremidades traseiras e aberturas para acomodar as travas em uma posição adiante das saliências. As aberturas são alinhadas com os furos vazados na borda. A trava inclui um arranjo de cunha e carretel.
