background technique:
In turbo machine running, the gas of High Temperature High Pressure brings the thrust of larger axis to machine group rotor, general ball bearing all cannot bear, and how balancing axial thrust is the emphasis studied always.But affect the many factors of axial force, gap between aerodynamic force, sound, the pressure of each chamber, whether there is bleed valve etc., many factors balance axial force research and bring larger difficulty, the axial force produced when therefore consideration thrust-bearing bears unit operation, therefore devise doubledirection thrust bearing and add the structure of roller bearing to bear rotor axial power, and be applied, effectively improve the life-span of bearing.
summary of the invention:
For the problems referred to above, the present invention proposes the reverse slide bearing of the two-way thrust of a kind of turbo machine, realizes the function of bearing bidirectional axial force by the thrust pad of two-sided thrust disc and both sides.
Technological scheme of the present invention is: a kind of turbo machine reverse slide bearing of two-way thrust, comprise reverse thrust bearing, reverse thrust bearing is arranged in bearing housing together with roller bearing, thrust disc is arranged on turbine shaft, adjustment ring is provided with between thrust disc and roller bearing, thrust bearing is fixed by bolts on bearing housing, and the thrust pad of reverse thrust bearing and thrust bearing coordinates with the thrust face of thrust disc;
Deboost bearing is primarily of bearing support, central ring, isolating ring and thrust pad composition, each part is all assemblied on bearing support, be fixed on gas turbine by bearing support, central ring and isolating ring are arranged on bearing support by screw, the central ring that the replaceable thickness of central ring is different, isolating ring is the support of thrust pad, isolating ring there is multiple square window, thrust pad pin is fixed in the square window of isolating ring, after fixing, pin afterbody counterbore is risen and expand locking, Spielpassung between pin and thrust pad, the edge of each square window of isolating ring has oil supply hole, silver-plated after the bit copper alloy of thrust pad surface, a lubricating oil path part for bearing support is communicated with the oil nozzle of roller bearing, a part is communicated with the oil supply hole of isolating ring by adapter.
The structure of thrust bearing is identical with the structure of reverse thrust bearing.
Before and after thrust disc, the surface roughness of thrust face is less than 0.2um, and Nitrizing Treatment is carried out on surface.
The present invention has following beneficial effect: by the structure of doubledirection thrust bearing, eliminates axial force adjustment, improves the life-span of bearing, improves unit bearing arrangement resistance tocrocking, improves reliability and the Security of unit.
