Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0010] like figure 1 As shown, the present invention includes a bracket 1 , a motor 2 , a speed reducer 3 and a connecting shaft 4 . The output end of the motor 2 is connected to the input end of the reducer 3, and the output end of the reducer 3 is fixedly connected to one end of the connecting shaft 4, and the other end of the connecting shaft 4 is provided with a meshing tooth surface, and the meshing tooth surface is hinged to the aero-engine 5 The mating tooth surfaces of the shaft match. Both the motor 2 and the reducer 3 are fixedly connected to the bracket 1, and the bracket 1 is also fixedly connected to the fan front case of the aero-engine 5. When the present invention is in use, the rotation of the motor 2 can drive the aero-engine 5 to rotate, so that rotating parts such as blades can be inspected.

[0011] Further, as figure 2 As sh...

Abstract

The invention relates to an apparatus for driving an aero-engine to rotate. The apparatus is characterized by comprising a support, a motor, a reducer, and a connecting shaft. The output end of the motor is connected with the input end of the reducer. The output end of the reducer is fixedly connected with one end of the connecting shaft. The other end of the connecting shaft is provided with a meshing tooth surface matching the meshing tooth surface of the articulated shaft of the aero-engine. The motor and the reducer are fixedly connected to the support. The support is fixedly connected tothe fan front casing of the aero-engine. The apparatus can rotate the aero-engine in virtue of the rotation of the motor in order to inspect the rotating parts such as blades and the like.

Description

technical field [0001] The invention relates to an aero-engine maintenance device, in particular to an aero-engine driving device. Background technique [0002] During the maintenance process of aero-engines, the most important and frequently performed maintenance link is the flow path inspection. Runner inspection is to extend the probe of the borescope into the flow passage of the aero-engine to check the fan blades, compressor blades, combustion chambers, turbine blades, etc. When inspecting the rotating parts of the core machine, it is necessary to turn the aeroengine to see the damage of the parts. However, in the prior art, the rotation of the rotating aero-engine is realized by the cooperation of multiple people using wrenches, which is not only laborious, but also inefficient for inspection. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an aero-engine belt drive device that can improve the insp...
