Abstract

1. Portabrocas para aparatos que funcionan en rotación, rotación-percusión, especialmente martillos perforadores, del tipo que comprende al menos dos garras de sujección desplazables radialmente, cuyas zonas de sujección dirigidas hacia el centro presentan una superficie de sujección de sección transversal configurada de forma convexa, caracterizado porque las garras de sujección (3, 13) están dotadas en sus vértices con una muesca (3d, 13d) que discurre en dirección longitudinal y se extiende en todo lo largo de la longitud de la zona de sujección (3b). 2. Portabrocas según la reivindicación 1, caracterizado porque la muesca (3d, 13d) tiene sección transversal en forma de V. 3. Portabrocas según la reivindicación 2, caracterizdo porque el ángulo de la abertura (alfa) de la muesca (3d, 13d) está comprendido entre 60º y 120º, siendo preferentemente de 90º. 4. Portabrocas según una de las reivindicaciones 1 a 3, caracterizado porque la distancia (b) de ambas aristas (3e, 13e) formadas por latransición de las muescas (3d, 13d) hasta la superficie de sujección (3c, 13c), asciende de 0,25 a 0,6 veces el radio de redondeado (R) del abombado convexo de las garras de sujección (3, 13). 5. Portabrocas según una de las reivindicaciones 1 a 4, caracterizado porque la distancia (b) de ambas aristas (3e, 13e) formadas por la transición de las muescas (3d, 13d) hasta la superficie de sujección (3c, 13c), es menor que el diámetro de vástago (d) más pequeño que puede sujetarse. 6. Portabrocas para el taladro por percusión.
