Field of the Invention The present invention relates to a bearing automatic air cleaner, and more particularly, to an automatic air cleaner for a bearing, which is capable of rotating the inner ring, the roller, and the rotating body, The present invention relates to a bearing automatic air cleaner which eliminates the blind spot and improves the cleaning quality.

On a train, the axle of a high-speed vehicle consists of a power axle and a carriage axle. An axle bearing is installed to support a load applied to the shaft and to rotate the shaft, and the axle bearing needs to be inspected according to use. The disassembly inspection period (TBO) of the axle bearing is about 1.4 million Km. The disassembly maintenance of the axle bearing according to the disassembly inspection period management is an essential element for preventing the operational trouble and the accident caused by the degradation of the bearing performance during the operation of the vehicle. Maintenance of these axle bearings is directly related to the performance of the bearings, which is directly related to the safety of the trains, so maintaining and cleaning the bearings is one of the most important bearing maintenance.

Thereafter, a series of operations for manually changing the position of the bearings and manually rotating the oil and remaining sludge between the bearing cage and the roller with the air gun repeatedly rotating the cage are still manually performed by the operator.

As a result, it is possible to cause musculoskeletal diseases of the worker because the operator repeatedly rotates the bearing cage and manually performs the air cleaning. Therefore, the manpower required by the manual air cleaning is required, the work environment is polluted by the vapor scattering and noise during the air cleaning, An operator needs to have an automated air cleaning system in order to solve various problems caused by the manual operation of the air cleaning operation and improve the working efficiency.

In order to solve the above problems, Korean Patent Registration No. 10-0923563 'Automatic bearing washing and cleaning method' has been proposed in the related art.

However, since the automatic cleaning apparatus according to the related art has a function of entirely returning the bearing, there is a problem that the cleaning quality is deteriorated due to the occurrence of a dead zone at the time of air cleaning.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiments of the invention and, together with the description, serve to:

FIG. 1 is a front view of a bearing automatic air cleaner 1000 according to the present invention, FIG. 2 is a side view of a bearing automatic automatic air cleaner 1000 according to the present invention, Fig.

1 is a front view of a bearing automatic air cleaner 1000 according to the present invention as a representative drawing of the present invention. 1, the bearing automatic air cleaner 1000 according to the present invention is a bearing air cleaner for cleaning a bearing. The bearing automatic air cleaner 1000 includes a driving unit 100 including a rotating shaft 124, A bearing cradle 200 coupled to the rotation shaft 124 of the driving unit 100 to fix the cleaning subject bearing 700 and a control unit 200 disposed at an upper portion of the driving unit 100 to inject air to the cleaning subject bearing 700, And an air jetting unit 300 for jetting air.

The driving unit 100 includes a frame 110 formed in a shape of a hollow and having a space formed therein, and a plurality of bearing internal air cleaners 1000, And a rotating part 120 provided on the rotating shaft. The shape of the frame 110 of the driving unit 100 is preferably a rectangular box shape, but is not limited to a specific shape. The height of the driving unit 100 is not limited as long as the bearing cleaning operation can be performed at the eye level of the standing user when the bearing for washing is mounted on the upper end of the driving unit 100, Is not limited as long as the cleaning subject bearing 700 can be stably placed on the cleaning subject bearing 700 and the cleaning subject bearing 700 can be cleaned.

At this time, the upper surface of the driving part 100 is formed with through holes passing through upper and lower parts. The through hole is a hole formed to project the rotation axis of the rotation part 120 to the outside of the driving part 100. Therefore, it is preferable that the diameter of the through hole is larger than the diameter of the rotation shaft of the rotation part 120.

On the other hand, a moving unit capable of moving the driving unit 100 is provided on a lower end surface of the driving unit 100. Preferably, the moving means is a caster 130 that is a moving wheel. It is preferable that the caster 130 is provided in two pairs so as to be symmetrical to the bottom edge of the driving unit 100. However, as long as the driving unit 100 can move in a balanced state of the driving unit 100, The number and position of the first and second electrodes 130 are not limited. The caster 130 can easily move the position of the driving unit 100 and fix it at a desired position.

In the driving unit 100, a rotation unit 120 is provided. The power source of the rotation unit 120 is preferably a motor 121. The motor 121 is vertically coupled to the inner top surface of the driving unit 100 and coupled to the rotation axis of the motor 121 so as to face upward.

It is preferable that a speed reducer 122 is provided between the motor 121 and the upper end of the driving unit 100 in order to reduce the rotation speed of the motor 121. [ The speed reducer 122 reduces the speed of the motor 121 by reducing the speed of the motor 121. The speed reducer 122 reduces the speed of rotation by a reduction ratio and increases a torque by a reduction ratio. When using a commonly used off-the-shelf motor, the rotation speed is too fast, so the bearings for cleaning rotate too fast and are not suitable for cleaning. At this time, the decelerator 122 is used to decelerate the speed at a speed that is easy to clean.

The type and size of the speed reducer are not limited as long as the speed reducer 122 has a speed reduction ratio enough to reduce the speed of the motor at a speed at which the bearing can be easily cleaned.

Meanwhile, it is preferable that a separate rotation shaft 124 is provided in the through hole formed in the upper end of the driving part 100. After the bearings are inserted into the through holes, the rotation shaft 124 is fixed to the inner ring of the bearing so as to be rotatable. Then, the rotation shaft of the speed reducer 122 and the rotation shaft 124 are coupled to each other by a coupling 123.

At this time, when the motor 121 rotates, the rotation speed of the motor 121 is reduced by the speed reducer 122 connected to the rotation shaft of the motor 121 so that the rotation axis of the speed reducer 122 rotates at a slow speed, The rotation axis 124 connected to the rotation axis of the speed reducer 122 is rotated.

The reason why the rotation axis of the speed reducer 122 is rotated without using the rotation axis of the speed reducer 122 directly is that the coupling 123 is used to rotate the other rotation axis 124. The reason is that if the rotation axis of the speed reducer 122 is directly used, Since repairs and replacement are cumbersome, the reason for using coupling is the same as that for using a coupling in a general rotary device, so that it is a technique that has already been started and commercialized and used, so a detailed description is omitted.

In addition, the driving unit 100 is provided with a control unit 600 for controlling the operation and rotation speed of the motor 121. The control unit 600 may be provided on any one of the side surfaces of the driving unit 100 to control the ON and OFF states of the motor 121 and the rotational speed of the motor 121.

A bearing cradle 200 is coupled to the rotation shaft 124.

Meanwhile, a fixing part 210 for fixing only the outer ring or the cage 730 of the cleaning object bearing 700 is provided on the upper part of the driving part 100. The fixing portion 210 fixes the outer ring or the cage 730 to rotate only the inner ring 710 and the rotating body 720 when the rotation shaft 124 rotates. When the outer ring or the cage 730 is fixed to the fixing portion 210, the outer ring or the cage 730 of the to-be-cleaned bearing 700 moves when the bearing cage 200 is rotated by the operation of the motor 121 And only the inner ring 710 and the rotating body 720 are rotated.

An air spraying part 300 for spraying high pressure air to the cleaning object bearing 700 is provided on the upper part of the driving part 100. The air injecting unit 300 injects high-pressure air to remove various foreign substances adhering to the cleaning subject bearing 700 and contaminating the bearing.

At this time, it is preferable that the conduit 320 can be moved by an external force of the user, and the conduit 320 can be fixed at a desired position. The pipeline 320 and the spray nozzle 330 are positioned at the most efficient position for cleaning while moving the position of the pipeline 320 in accordance with the type and size of the cleaning object bearing 700, Thereby enabling efficient bearing cleaning.

A vapor cover 500 for accommodating the bearing mount 200 and the air spraying unit 300 is provided at an upper portion of the driving unit 100. The vapor cover 500 is provided so as to be easily detachable and detachable.

In the course of cleaning the to-be-cleaned bearings 700, there arises a problem that oil or foreign matter is scattered to the outside due to the high-pressure air generated in the air injecting unit 300. At this time, It is preferable that the cover is formed to be large enough to accommodate the entire top surface of the driving unit 100. [
