Abstract

Предложено долото для бурения грунта, содержащее режущую шарошку, которая закреплена на лапе, и уплотнительный узел зазора, который формирует динамическое уплотнение с радиальной поверхностью зазора лапы. Уплотнительный узел зазора содержит жесткое уплотняющее кольцо, имеющее удлиненный плечевой участок и укороченный плечевой участок. Удлиненный плечевой участок продолжается наружу от укороченного плечевого участка и сцепляется с радиальной поверхностью зазора лапы.
