Abstract
A device for enabling two elements connected by a knuckle to take a disalignment angle with respect to one another in a single displacement plane. One of the elements is a lower element extending beyond the knuckle and is shaped as a lever arm located in the second element which forms the upper element. The knuckle is fashioned as a ball joint, with a guiding arrangement being provided for holding the displacement of the drill elements in the displacement plane. The guiding means are integrated into the upper element and, in the upper element, a control arrangement is provided for controlling the disalignment angle with the controlling arrangement including an eccentric having the positioned determined by the disalignment angle.
Claims13
A device for enabling two elements connected by a knuckle to take a disalignment angle with respect to one another, in a single displacement plane, a lower element of the two elements extends beyond the knuckle shaped as a lever arm located in a hollow upper element forming the second element of the two elements, wherein the knuckle a ball joint type, said device comprises guiding means holding the displacement of the two elements in said displacement plane, said means being integrated into the upper element, said device also comprises, in the upper element, means for controlling said disalignment angle, and wherein said control means comprise an eccentric whose position determines said disalignment angle.
