Abstract
Raccord fileté pour sondage à percussion comprenant au moins un filetage mâle (10) disposé sur un bout mâle (11) et un filetage femelle (17) situé à l'intérieur d'un manchon. Les filets sont cylindriques et comportent une surface extérieure de butée (20) à une extrémité libre du manchon, ainsi qu'une surface de contact (14) située sur le bout mâle. De plus, ils comportent une surface intérieure de butée (21) située dans le manchon et une surface terminale (16) à l'extrémité libre du bout mâle. Un jeu (.delta.) initial existe entre la surface terminale (16) du bout mâle et la surface intérieure de butée (21) du manchon, ce jeu étant éliminé après l'usure du raccord fileté. L'agrandissement de l'angle du pas (.alpha.) des filets (19, 17) permet de limiter le serrage du raccord, sous l'effet de la butée inférieure d'épaulement, tout en lui conservant une durée de vie acceptable.
