Abstract
The utility model discloses a gear for transmission cases of airplanes, which relates to the improvement technology of gear structures, and concretely relates to the improvement technology of gear structures for transmission cases of airplanes. The gear for transmission cases of airplanes disclosed by the utility model discloses a gear (1) for transmission cases of airplanes; a through hole (2) is arranged below each tooth of the gear (1), the through hole (2) passes through the two end faces of the gear (1), the top of the gear (1) is provided with a lubrication hole (3), and the lower end of the lubrication hole (3) is communicated with the through hole (2). The gear disclosed by the utility model solves the problem that the top of the existing gear for transmission cases of airplanes is lubricated unevenly, so that the top of the gear is abraded, thereby causing potential safety hazards.
Description
Technical field
The utility model relates to the improvement technology of gear structure, is specifically related to the improvement technology of aircraft gearbox gear structure.
Background technique
Aircraft has gear oil lubricated with the lubricating system of gearbox, quasi-hydrodynamic lubrication grease lubrication, and solid lubricant lubricates several kinds of modes.The gearbox sealing of aircraft is relatively good, and rotating speed is higher, and the big general gear oil that uses of load is lubricated.When the aircraft gearbox lubricated, the wheel tooth top was lubricated inhomogeneous, made the tooth wearing and tearing, caused hidden danger.
The model utility content
The utility model provides a kind of gear that is used for the aircraft gearbox, and it is lubricated inhomogeneous that the utility model has solved existing aircraft gearbox gear top, makes the tooth wearing and tearing, causes the problem of hidden danger.
For addressing the above problem, the utility model adopts following technological scheme: be used for the gear of aircraft gearbox, comprise the gear (1) of aircraft gearbox; There is a through hole (2) below of going up each tooth at gear (1), and through hole (2) connects the both ends of the surface of gear (1), at gear (1) top lubrication hole (3) is arranged, and lubrication hole (3) lower end is communicated with through hole (2).
The advantage of the utility model: during the gear operation,,, avoid the wearing and tearing of gear top, the Security that has improved working gear for the gear top provides sufficient, lubricated uniformly because action of centrifugal force is lubricated by the top that flows to gear through through hole and lubrication hole.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional view of Fig. 1.
Symbol description among the figure: gear 1, through hole 2, lubrication hole 3.
Embodiment
With illustrated embodiments the utility model is done detailed explanation below.
Shown in Fig. 1-2, be used for the gear of aircraft gearbox, comprise the gear (1) of aircraft gearbox; There is a through hole (2) below of going up each tooth at gear (1), and through hole (2) connects the both ends of the surface of gear (1), at gear (1) top lubrication hole (3) is arranged, and lubrication hole (3) lower end is communicated with through hole (2).
What should explain at last is: obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not qualification to mode of execution.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all mode of executions.And conspicuous variation of being amplified out thus or change still are among the protection domain of the utility model.
Claims (1)
1. the gear that is used for the aircraft gearbox comprises the gear (1) of aircraft gearbox; It is characterized in that there is a through hole (2) below of going up each tooth at gear (1), through hole (2) connects the both ends of the surface of gear (1), at gear (1) top lubrication hole (3) is arranged, and lubrication hole (3) lower end is communicated with through hole (2).
