Abstract
Изобретение относитс к горному делу и предназначено дл бурени скважин в породах различной крепости. Цель - повышение надежности устр-ва в работе путем исключени выпадани замковых тел качени в процессе бурени . С пневмоударником 2 жестко соединена букса 1 с центральным отверстием 5 под хвостовик коронки. Отверстием 5 вскрыты продольные каналы 6 под ведущие тела качени - шары 7 и каналы 8 под замковые тела качени - шары 9. В канавке 11 буксы расположено стопорное кольцо (К) 12, а между ним и шарами 9 - разрезное упругое опорное К 13. Диаметр канавки 11 под К 13 выполнен равным диаметру канавки 11 под К 12. Ширина канавки 11 под К 12 и 13 равна суммарной их толщине . Длина К 13 выполнена равной длине канавки 11. Такое исполнение К 12 и 13 полностью исключает самопроизвольное выпадание К 12 из канавки 11 в процессе работы. При ударе по хвостовику коронка увлекает за собой шары 7 и 9, которые дав т на К 13. а оно через К 12 компенсирует эту энергию. Крут щий момент от пневмоудар- ника к коронке передаетс через шары 7 и 9. 1 з.п. ф-лы, 3 ил. со сThe invention relates to mining and is intended for drilling wells in rocks of different strengths. The goal is to increase the reliability of the device in operation by eliminating the rolling lock bodies falling out during drilling. The pneumatic hammer 2 is rigidly connected to the bush 1 with the central hole 5 under the shank of the crown. Hole 5 opened the longitudinal channels 6 under the leading body rolling - balls 7 and channels 8 under the lock body swing - balls 9. In the groove 11 of the axle box there is a snap ring (K) 12, and between it and the balls 9 is a split elastic support K 13. Diameter the grooves 11 under K 13 are made equal to the diameter of the grooves 11 under K 12. The width of the grooves 11 under K 12 and 13 is equal to their total thickness. The length K 13 is made equal to the length of the groove 11. Such a design K 12 and 13 completely excludes the spontaneous falling out of K 12 from the groove 11 during operation. Upon impact on the shank, the crown carries the balls 7 and 9 behind them, which press on K 13. and it compensates for this energy through K 12. The torque from the air hammer to the crown is transmitted through balls 7 and 9. 1 s. f-ly, 3 ill. with s
