Description
Известные долоть обладают тем недостатком, что при повторном и многократном их использовании ланы долота отрезаютс но сварному шву, что при 5сдит К преждевре: 1енкому нзиосу как корпуса долота , так и .-lan.Known chisels have the disadvantage that when they are used repeatedly and repeatedly, the lans of the chisel are cut off but the weld seam, which, if taken 5 seconds, means that the bit corps and the.-Lan are damaged.
В описываемом долоте эти недостатки устранены тем, что ланы выполнепЕзГ съемными и механически сочлен емыми с корпусом до.юта.In the described bit, these disadvantages are eliminated by the fact that the lanes are made removable and mechanically connected to the hull.
На чертеже схематически изображено йюлото.The drawing schematically shows yuloto.
Корпус долота как обычно нрпсоедин етс к бурилыюГ ко.юние на резьбе /. В хорнусе мехапнческпм нутем выполнены назы 2 дл присоединени лап.
