Abstract
Изобретение относитс к породо- разрушающему буровому инструменту и позвол ет повысить долговечность работы долота путем более равномерного распределени нагрузки по подшипникам и венцам шарошек. Долото содержит лапы 2 с цапфами 1, много- венцовые шарошки 6, удерживаемые на цапфах 1 посредством замкового шарикового подшипника 4. Последний размещен между периферийным и концевым 3 опорными подшипниками. Все венцы расположены на шарошках 6 согласно соотношению (A-R) d/2, где А - максимальное рассто ние от оси долота до центра шарика замкового подшипника 4; R - максимальное рассто ние от оси долота до точки пересечени оси симметрии венца с образующей шарошки ; d - диаметр шарика замкового подшипника 4. При выполнении этого услови обеспечиваетс уменьшение неравномерности распределени осевой нагрузки по отдельным подшипникам и венцам шарошки. 1 ил. (ЛThe invention relates to a rock-destroying drilling tool and allows to increase the durability of the bit operation by more evenly distributing the load on the bearings and rims of the cones. The chisel contains legs 2 with trunnions 1, multi-circular cones 6, held on trunnions 1 by means of a lock ball bearing 4. The latter is placed between the peripheral and end 3 support bearings. All rims are located on the roller cutters 6 according to the ratio (A-R) d / 2, where A is the maximum distance from the axis of the bit to the center of the ball of the lock bearing 4; R is the maximum distance from the axis of the bit to the point of intersection of the axis of symmetry of the ring with the forming roller cone; d is the diameter of the ball of the bearing 4. When this condition is satisfied, the uneven distribution of the axial load among the individual bearings and roller cones is reduced. 1 il. (L
