Abstract

La invencion proporciona un conjunto de expansion para un perno para roca que incluye: un ancla de expansion que se extiende entre un extremo distal y un extremo proximal, comprendiendo el ancla; una formacion de union; y una pluralidad de aletas de expansion, teniendo cada aleta un cuerpo con una superficie exterior cilindrica formada con una pluralidad de dientes serrados que se extienden de manera circunferencial alrededor de la superficie exterior, y una superficie interior de seccion decreciente lisa que, cuando las aletas se mantienen juntas por la formacion de union, proporcionan un paso de seccion decreciente que es de seccion decreciente hacia dentro desde el extremo distal hasta el extremo proximal; y un taco de seccion decreciente que puede acoplarse a un perno para roca y que se dispone para pasar al interior del paso de seccion decreciente desde el extremo proximal para separar las aletas; en el que cada diente serrado esta definido por una superficie conica y una superficie rebajada que se extiende de manera lateral con relacion al eje del paso; y en el que la pluralidad de dientes serrados incluye una primera serie de dientes serrados que comienzan de manera adyacente al extremo distal, teniendo cada diente serrado de esta serie una superficie rebajada con una anchura en un primer intervalo; y una segunda serie de dientes serrados, teniendo cada diente serrado de esta serie una superficie rebajada que es mas ancha progresivamente que el diente serrado anterior de la segunda serie, esta serie avanza hacia el extremo proximal, con una anchura en un segundo intervalo.
