Abstract
The utility model discloses a power turbine gear which comprises a gear disc. Multiple gear teeth are arranged at an edge around the gear disc, a nickel plated layer is arranged on the surface of the gear disc, a wear-resistant layer is arranged on surfaces of the multiple gear teeth, a through hole is arranged in the middle of the gear disc, multiple open holes are arranged, surrounding the through hole, on the gear disc, and aluminum filler is filled in the multiple open holes respectively. The power turbine gear is rational in structure, and the wear-resistant layer and the nickel plated layer covers on the surfaces of the gear teeth and the gear disc, so that high wear resistance and rusting prevention are realized. In addition, the open holes are arranged on the gear disc and filled with the aluminum filler, so that sound insulation and noise reduction are realized.
Description
Technical field
The utility model relates to field of gears, specifically a kind of power turbine gear.
Background technique
Power turbine is in gas turbine engine, is the turbomachine that mechanical work is used for driving external loading (such as propeller cavitation or rotor etc.) with the transformation of energy of combustion gas.
The power turbine gear is the common gearing parts of vehicle turbine engine interior.Larger wearing and tearing appear in power turbine gear in the course of the work, also can produce a large amount of noises, work long hours in rugged environment comparatively, can get rusty in its surface.
The model utility content
The purpose of this utility model provides a kind of power turbine gear, is covered with respectively wearing layer and nickeling layer on the surface of the gear teeth and wheel disc, to play wear-resisting and anti-effect of getting rusty; In addition, offer a plurality of perforates at wheel disc, and in perforate filled and process aluminium packing, to reach the purpose of sound insulation and noise reduction.
The technical solution of the utility model is as follows:
A kind of power turbine gear, include wheel disc, edge, surrounding around wheel disc has respectively a plurality of gear teeth, it is characterized in that: the surface of described wheel disc has nickeling layer, the surface of described a plurality of gear teeth has wearing layer, the middle part of described wheel disc is provided with through hole, and the wheel disc around through hole is provided with a plurality of perforates, is filled with respectively the filled with foam aluminum thing in described a plurality of perforates.
Described power turbine gear is characterized in that: have live axle from described through hole, to pass and with the through hole interference fit.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, is covered with respectively wearing layer and nickeling layer on the surface of the gear teeth and wheel disc, has played good wear-resisting and anti-effect of getting rusty; In addition, offer a plurality of perforates at wheel disc, and in perforate filled and process aluminium packing, reached the purpose of sound insulation and noise reduction.
