Abstract
Турбобур, содержащий корпус, в полости которого размещен уступообразный ротор в поперечном сечении, отличающийся тем, что уступы на роторе выполнены имеющими зазор с корпусом, между уступами расположены выдвинутые относительно них в сторону корпуса полуцилиндрические участки, внешней стороной скользяще контактирующие с внутренней стенкой корпуса, при этом уступы и полуцилиндрические участки разделены выпуклыми поверхностями кнаружу.A turbo-drill containing a body, in the cavity of which a step-like rotor is placed in cross section, characterized in that the steps on the rotor are made with a gap with the case, between the steps there are semi-cylindrical sections extended relative to them towards the case, sliding contact with the inside wall of the case, with In this case, the ledges and semicylindrical sections are separated by convex surfaces of the kreuzu.
