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. Сечение пазов соответствует сеченпю хвостовика , и выполнено в части, наход щейс  около шарон1кп, пр моугольным, а затем переходит в трапецеидаль ное. В хвостовике лапы высверлено отверстие 3 дли болта 4 с резьбой 5, KOTOjihni скрепл ет лапу с корпусом долота.The body of the bit is normally connected to drill bits on the thread /. In the hornus, mech-nickname is made of nazu 2 for attaching the paws. The cross section of the grooves corresponds to the section of the shank, and is made in the part located near the sharon1kp rectangular, and then becomes trapezoidal. A hole 3 is drilled in the shank of the paw for the length of the bolt 4 with thread 5, KOTOjihni fastens the paw to the bit body.
