FIELD: oil production industry, particularly for development, repair and drilling oil and gas wells. ^ SUBSTANCE: facility has frame, drill derrick and drawworks with drilling and bailing drums assembled on the frame, power-driven reduction gear, drive transmission of drilling and bailing drums connecting them with power-driven reduction gear and provided with leading and driven members. Each transmission is arranged in rigid one-piece oil-filled body. Driven member of the transmission has hollow shaft put on shaft cantilever of corresponding drawworks drum. Shafts of leading and driven member are mounted in above body by bearings. Body is provided with hinged unit arranged from leading member side and adapted to support thereof by the frame. Leading member shaft is connected to power-driven reduction gear through double cardan joint. ^ EFFECT: multiple decreasing of side loads applied to drawworks drum shaft cantilevers, increased life of transmission members and simplified transmission assembling and disassembling. ^ 4 cl, 9 dwg |
