Abstract
Barrena de perforación para perforación de tierra, refrigerada por aire, que incluye una pluralidad de partes terminales. Cada parte terminal incluye un reborde de pasador. Un primer anillo de rodadura de rodillos es distal al reborde de pasador. Un reborde de empuje es distal al primer anillo de rodadura de rodillos. Al menos una ranura 71 de ventilación de reborde de pasador está dispuesta en una superficie del reborde de pasador opuesta al primer anillo de rodadura de rodillos. La al menos una ranura 81 de ventilación de reborde de pasador se abre en una dirección de un lado de carga de un cojinete. Al menos una ranura 71 de ventilación de reborde de empuje está dispuesta en una superficie del reborde de empuje que está orientada hacia los primeros rodillos. La al menos una ranura 81 de ventilación de reborde de empuje se abre en la dirección del lado de carga del cojinete. Una pluralidad de conductos de flujo están dispuestos dentro de la parte terminal para suministrar fluido a la al menos una ranura 71 de ventilación de reborde de pasador y la al menos una ranura 81 de ventilación de reborde de empuje.
