Disassembling and assembling device for high-pressure turbine front baffle
2016
The invention relates to design of auxiliary equipment for high-pressure turbines of aircraft engines, in particular to a disassembling and assembling device for a high-pressure turbine front baffle. The disassembling and assembling device comprises an assembling and disassembling ring, a supporting frame, a connecting seat, an axial load pull rod, a spline shaft, a torque amplifier, a spline transition section and an axial load nut, wherein the assembling and disassembling ring is arranged on one side of the front baffle in a sleeving mode; the supporting frame is coaxially fixed to one side of the assembling and disassembling ring; the connecting seat is located in an inner cavity of the supporting frame and fixedly connected with a high-pressure turbine disc through a fixing part of the connecting seat; one end of the axial load pull rod coaxially penetrates through a through hole of the fixing part; the axial load pull rod is coaxially sleeved with the spline shaft, the outer ring face of the spline shaft is arranged at one end of the supporting frame through a thrust ball bearing, and one end of the spline shaft is arranged in an accommodating part of the connecting seat in a matched mode through splines; the torque amplifier is coaxially and fixedly arranged at the end, away from the assembling and disassembling ring, of the supporting frame; the spline transition section is arranged between the spline shaft and the torque amplifier; and the axial load nut is arranged at one end of the axial load pull rod. By means of the disassembling and assembling device for the high-pressure turbine front baffle, torque required for assembling and disassembling of the front baffle can be stably loaded.
