Abstract
1. Буровое долото, включающее одну, по меньшей мере, лапу с цапфой, шарошку, подшипниковую опору скольжения, образованную втулкой, радиальные и торцовые поверхности которой сопряжены с ответными поверхностями в шарошке, на основании цапфы и на цапфе, и уплотнение между цапфой и шарошкой, отличающееся тем, что указанная втулка неподвижно соединена с цапфой, а торцовая поверхность этой втулки со стороны основания цапфы подвижно сопряжена с ответной поверхностью замковой втулки, вставленной и неподвижно соединенной с шарошкой со стороны основания цапфы. ! 2. Уплотнение между цапфой и шарошкой герметизированной подшипниковой опоры бурового долота, включающее торцовую пару сопряженных вращающегося и невращающегося металлических колец и амортизатор, отличающееся тем, что амортизатор выполнен в виде кольцеобразной мембраны, которая по периметру своей внутренней окружности соединена с вращающимся торцовым металлическим кольцом, а по периметру наружной окружности связана с шарошкой. ! 3. Уплотнение по п.2, отличающееся тем, что кольцеобразная мембрана по периметру своей наружной окружности связана с шарошкой посредством втулки, вставленной и соединенной с шарошкой со стороны основания цапфы. ! 4. Уплотнение по п.2, отличающееся тем, что невращающееся металлическое кольцо уплотнения вставлено в торец основания цапфы. 1. A drill bit comprising at least one leg with a trunnion, a roller cutter, a sliding bearing supported by a sleeve, the radial and end surfaces of which are mated with mating surfaces in the roller cutter, on the base of the trunnion and on the trunnion, and a seal between the trunnion and roller characterized in that the said sleeve is fixedly connected to the pin, and the end surface of this sleeve from the side of the pin of the pin is movably mated to the counter surface of the locking sleeve inserted and fixedly connected to the cone from the main axles. ! 2. The seal between the pin and the cone of the sealed bearing support of the drill bit, including an end pair of conjugated rotating and non-rotating metal rings and a shock absorber, characterized in that the shock absorber is made in the form of an annular membrane, which is connected to a rotating end metal ring along the perimeter of its inner circumference, and around the perimeter of the outer circumference is connected with a cone. ! 3. The seal according to claim 2, characterized in that the annular membrane around the perimeter of its outer circumference is connected to the cone by means of a sleeve inserted and connected to the cone from the side of the base of the journal. ! 4. The seal according to claim 2, characterized in that the non-rotating metal seal ring is inserted into the end face of the journal.
