FIELD: engines and pumps.SUBSTANCE: intermediate case of a two-flow jet turbine engine includes at least one annular partition wall for separation of a gas flow into two annular concentric flows, primary and secondary ones respectively. Between inner hub and outer cylindrical shell there located is a variety of radial racks. At least one of the racks is hollow and includes the first part passing through primary flow and the second part passing through secondary flow. In the above radial rack there installed with possibility of being rotated is a transmission shaft of the drive of auxiliary units. The first end of the transmission shaft passes through the inner hub, and the second end passes through outer cylindrical shell. Inner volume of the radial rack consists of one section, in which the transmission shaft is arranged and which forms a channel for lubricating fluid. The other object of the invention is a jet turbine engine containing a chamber with support bearings, a gear box of auxiliary units and the above described intermediate case. Radial rack of the case provides interaction between the chamber and the gear box of auxiliary units.EFFECT: invention allows laying the auxiliary equipment of the engine in the structural rack of the case.8 cl, 5 dwg |
