Abstract

The utility model relates to an aircraft power plant, and particularly discloses a power input rear shaft sleeve adjusting device. The power input rear shaft sleeve adjusting device comprises a shaft sleeve (1). A pair of clamping hoops (2) is oppositely arranged in the shaft sleeve (1), each clamping hoop (2) is of an arc structure, the reverse side of each clamping hoop (2) is provided with a screw (3), the screws (3) are arranged in threaded holes in the shaft sleeve (1), the inner end of each screw (3) is of a hemispherical structure, and the hemisphere faces abut against the clamping hoops (2). The power input rear shaft sleeve adjusting device solves the problem that due to the fact that a big interval appears in the installation process of an aircraft power plant rear shaft, normal operation of the aircraft power plant is influenced.

Description

Power input rear axle housing setting device
Technical field
The utility model relates to aircraft power plant, is specifically related to aircraft power input rear axle housing setting device.
Background technology
Aircraft power plant is the driving engine of aircraft and the general name that guarantees the necessary system of engine work and annex.Aircraft power plant is mainly driving engine and starting thereof, maneuvering system, driving engine is converted to mechanical energy by the chemical power of fuel oil, then drive screw propeller and accelerate outside air generation thrust or pulling force (as piston aviation engine and propeller turbine), or directly discharge backward combustion gas acquisition reaction thrust (as jet engine and rocket engine).Turbojet must reach certain rotating speed and could work, and the Main Function of start system accelerates to driving engine workable rotating speed exactly.Difference according to requirements, start mode is divided into compressed air starting aid, electronic starting and compact internal combustion engine starting.
The aircraft power plant rear axle there will be very large gap in installation process, and excessive clearance can produce larger vibration, affects the normal operation of aircraft power plant.
Summary of the invention
The utility model provides power input rear axle housing setting device, and the utility model has solved the aircraft power plant rear axle and there will be very large gap in installation process, affects the problem of the normal operation of aircraft power plant.
For addressing the above problem, the utility model adopts following technical scheme: power input rear axle housing setting device, comprise axle sleeve 1, be arranged at a pair of ferrule 2 in axle sleeve 1, described ferrule 2 is arcuate structures, and a pair of ferrule 2 is oppositely arranged, respectively be provided with a screw 3 at each ferrule 2 back side, screw 3 is arranged in the tapped bore on axle sleeve 1, and screw 3 the inners are hemisphere face structures, and hemisphere face withstands on ferrule 2.
Advantage of the present utility model: can adjust easily the gap of axle sleeve and power input rear axle, simple in structure, with low cost, easy to use.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1.
Nomenclature in figure: axle sleeve 1, ferrule 2, screw 3.
The specific embodiment
below with best embodiment, the utility model is described in detail .
As shown in Figure 1-2, power input rear axle housing setting device, comprise axle sleeve 1, be arranged at a pair of ferrule 2 in axle sleeve 1, described ferrule 2 is arcuate structures, and a pair of ferrule 2 is oppositely arranged, respectively be provided with a screw 3 at each ferrule 2 back side, screw 3 is arranged in the tapped bore on axle sleeve 1, and screw 3 the inners are hemisphere face structures, and hemisphere face withstands on ferrule 2.
Ferrule is held on power input rear axle outside, by screw, adjusts ferrule and rear shaft clearance.
Finally it should be noted that: obviously, above-described embodiment is only for the utility model example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being amplified out thus or change are still among protection domain of the present utility model.
