AI Technical Summary
Existing aircraft bearing cleaning equipment cannot guarantee that all parts of the inner and outer rings of the bearing can be thoroughly rinsed. In particular, the water impact force is insufficient in areas where the nozzle is not directly aligned, making it difficult to remove dirt.
A cleaning device for aero-engine bearings has been designed, comprising a tank, a support assembly, first and second flushing assemblies, and a transmission assembly. The first flushing assembly generates a reaction force to flush the inner ring, driving it to rotate and causing the second flushing assembly to reverse, thereby achieving all-round cleaning of the inner and outer rings.
This ensures that every area of the bearing's inner and outer rings receives sufficient impact force to effectively remove dirt and avoids the formation of cleaning dead zones.

[0019] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings, in which several embodiments of the present application are given. However, the present application can be implemented in different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.
[0020] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can be a middle element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there can be a middle element. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.
[0022] Please refer to the accompanying drawings Figures 1-3 The cleaning device for an aero-engine bearing comprises a tank body 1, a cover body 2 arranged above the tank body 1, a base 3 arranged below the tank body 1, a pollution discharge port 4 arranged on the tank body 1, a support assembly arranged in the tank body 1 for placing multiple layers of bearings, a first flushing assembly arranged in the tank body 1 for cleaning the inner rings of the bearings, a second flushing assembly arranged in the tank body 1 for cleaning the outer rings of the bearings, and a transmission assembly arranged between the first flushing assembly and the second flushing assembly.
[0023] The specific operation process of the present application is as follows: multiple bearings are placed on the support assembly, then the support assembly is placed into the tank body 1, water is supplied to the first flushing assembly and the second flushing assembly, the first flushing assembly is used to flush the inner rings of the multiple layers of bearings, the second flushing assembly is used to flush the outer rings of the multiple layers of bearings, the first flushing assembly is driven to rotate by the backwash force of the first flushing assembly, and the first flushing assembly drives the second flushing assembly to rotate through the transmission assembly, the first flushing assembly and the second flushing assembly continuously change the flushing area of the bearings, and the impact force of the first flushing assembly pushes the inner ring of the bearing to rotate from time to time, and the rotation of the inner ring of the bearing can prevent the support assembly from blocking the flushing area.
[0024] Please refer to the accompanying drawings Figure 2 and Figure 3The supporting assembly comprises a supporting shaft 5 arranged inside the tank body 1, a support 6 arranged on the supporting shaft 5, and a plurality of supporting blocks 7 arranged on the support 6.
[0025] The supporting shaft 5 is fixedly arranged inside the tank body 1, and a hole is arranged on the supporting shaft 5. The support 6 is arranged on the supporting shaft 5 by inserting a rod into the hole. The supporting blocks 7 are used to support the bearing. Preferably, the bearing is placed by inserting a clamping block on the supporting block 7 into the area of the outer wall of the bearing rolling ring, so as to prevent the rotation of the inner ring of the bearing. If two clamping blocks are needed to be attached to the inner and outer rings of the bearing to limit the bearing, the inner ring of the bearing cannot rotate, and the area will be blocked by the support 6. Therefore, the angle needs to be adjusted manually during the cleaning of the bearing to prevent the area from not being washed.
[0026] Please refer to Figure 2 and Figure 3 The first washing assembly comprises a rotating block 8 and a booster nozzle 9. A plurality of rotating blocks 8 are arranged on the supporting shaft 5, and three booster nozzles 9 are arranged in a circular array on each rotating block 8.
[0027] The rotating block 8 is rotationally connected to the supporting shaft 5, and the plurality of rotating blocks 8 are connected to each other. The included angle between the nozzle of the booster nozzle 9 and the water pipe is 120°, and the included angle between each booster nozzle 9 is also 120°. Therefore, when the three booster nozzles 9 spray water, the reaction force generated by the spraying is sufficient to drive the rotating block 8 to rotate. In this way, the booster nozzles 9 can continuously rotate to spray water. In addition, due to the angle arrangement of the booster nozzles 9, the booster nozzles 9 and the inner ring of the bearing are not perpendicular to each other. Therefore, the impact force of the water sprayed by the booster nozzles 9 can also drive the inner ring of the bearing to rotate.
[0028] Please refer to Figure 3 The transmission assembly comprises a rotating disc 12 arranged inside the base 3, and the lowermost rotating block 8 is connected to the rotating disc 12. The transmission assembly further comprises a rotating ring 13 arranged inside the base 3. A first tooth block 14 is arranged on the rotating disc 12, and a second tooth block 15 is arranged on the rotating ring 13. The first tooth block 14 is engaged with the second tooth block 15. The second washing assembly comprises a connecting pipe 10 arranged in a circular array on the rotating ring 13, and a plurality of spray heads 11 are arranged on the connecting pipe 10.
[0029] When the rotating block 8 rotates, the rotating chassis 12 is driven to rotate, the rotating chassis 12 rotates and drives the rotating ring 13 to rotate through the first gear block 14 and the second gear block 15 transmission, the rotating ring 13 drives the connecting pipe 10 to rotate, the connecting pipe 10 drives the multi-layer spray head 11 to rotate and sprays the bearing outer ring area, the spray head 11 and the bearing outer ring are in a vertical state, so that the spraying effect is better, if the bearing is supported on the support block 7 clamping block, the outer ring will be washed, if the bearing is between the two clamping blocks, the bearing needs to be rotated to adjust the position, and it does not need to worry that it will be blocked by the clamping block.
[0030] The utility model has been described exemplarily above in combination with the drawings, and obviously, the specific implementation of the utility model is not limited by the above-mentioned mode, as long as this kind of non-essential improvement using the method concept and technical scheme of the utility model or directly applying the concept and technical scheme of the utility model to other occasions without improvement is within the protection scope of the utility model.
