Japanese Unexamined Patent Publication No. 2007-21165

However, if semi-solid dirt, which is a mixture of dust and grease, is stuck inside the bearing, it may take a lot of labor and time to manually scrape off the dirt. ..
Multiple bearing floor plates are arranged on the turnout, and each bearing floor plate is provided with a number of bearings, so if it takes time to clean each bearing, the train will not operate. It was sometimes difficult to complete the cleaning and maintenance work performed at night within the specified work time.

An object of the present invention is to provide a bearing cleaning tool capable of suitably cleaning a bearing of a bearing floor plate.

In order to achieve the above object, the present invention
Bearing cleaning for cleaning a bearing which has a sphere and a frame-shaped member having a circular opening and holds a part of the sphere exposed from the opening on the upper surface of the bearing floor plate so as to be rotatable. It ’s an instrument,
A roller that is attached to an electric screwdriver device and is connected to the tip end side of a long rotating first rotating shaft that rotates around a second rotating shaft that intersects the first rotating shaft.
A posture stabilizing member that extends along the first rotation axis, has a base end portion attached to the electric screwdriver device, and is arranged so that the tip end portion is located in the vicinity of the roller.
By bringing the tip of the posture stabilizing member into contact with the frame-shaped member while the roller rotated by the electric screwdriver device is in contact with the sphere, the displacement of the roller with respect to the bearing is regulated. It was configured to be.

If this bearing cleaning tool is attached to the electric screwdriver device, the rollers of the bearing cleaning tool can be rotated by operating the electric screwdriver device.
The sphere can be easily rotated by bringing the roller rotated by the driving force of the electric screwdriver device into contact with the sphere of the bearing and transmitting the rotational force of the roller to the sphere.
In this way, if the bearing cleaning tool is attached to the electric driver device and used, the sphere of the bearing can be forcibly rotated by the roller that rotates at high speed, and the sphere that is forcibly rotated clogs the inside of the bearing. It is possible to preferably perform cleaning that scrapes off the dirt that has been stuck.

In particular, the misalignment of the roller with respect to the bearing is regulated by bringing the tip of the posture stabilizing member into contact with the frame-shaped member of the bearing while the roller rotated by the electric screwdriver device is in contact with the sphere of the bearing. The sphere of the bearing can be suitably rotated by the roller.
In other words, it was difficult to keep the roller in contact with the bearing because the roller was easily displaced from the bearing due to the reaction of the rotational force just by bringing the roller rotated at high speed into contact with the sphere of the bearing. If the misalignment of the rollers is regulated by bringing the tip of the posture stabilizer into contact with the bearing in the state of contact, the rotating roller can continue to contact the bearing and is clogged inside the bearing. Cleaning that scrapes off dirt can be performed well.

Also, preferably
The roller is a rubber member, and a plurality of convex portions are provided on the outer peripheral surface of the roller.
Since a plurality of convex portions are provided on the outer peripheral surface of the rubber roller, the sphere of the bearing can be firmly gripped and rotated.

Also, preferably
The convex portion has a substantially truncated cone shape, and the outer one in the width direction of the roller is formed so that the position of the tip from the center of the roller is higher.
By doing so, it becomes easy to bring the plurality of convex portions provided on the outer peripheral surface of the roller into close contact with the surface of the sphere of the bearing.
Further, since the convex portion of the roller has a substantially truncated cone shape, it is not easily damaged such as broken, and the sphere can be strongly gripped and appropriately rotated.
Also,

Also, preferably
At the tip of the convex portion, an inclined surface that descends toward the center in the width direction of the roller is formed, and the inclined surface of the convex portion on the outer side in the width direction of the roller has a larger angle with the axis of the roller. To do so.
By doing so, the tip surfaces of the plurality of convex portions provided on the outer peripheral surface of the roller can be more easily brought into close contact with the surface of the sphere of the bearing.

Also, preferably
At least three protrusions are provided at the tip of the posture stabilizing member.
When the tip of the posture stabilizing member is brought into contact with the frame-shaped member of the bearing, at least three protrusions abut against the frame-shaped member, so that the posture of the bearing cleaning tool is more stable.

Also, preferably
At least one of the protrusions should be flexible.
For example, the tip of the posture stabilizing member is strongly pushed against the bearing so that at least one of the three protrusions is elastically deformed rather than the three protrusions being brought into contact with the frame-shaped member of the bearing. The roller and the sphere of the bearing can be brought into close contact with each other in the contacted state.
When the roller and the sphere are brought into close contact with each other, the rotational force of the roller can be easily transmitted to the sphere. Therefore, when the roller is difficult to rotate, the degree of adhesion between the roller and the sphere may be adjusted in this way.

Also, preferably
A roller type brush that can be replaced with the roller attached to the second rotating shaft is provided.
If a bearing cleaning tool replaced with a roller-type brush is attached to an electric screwdriver device and used, it is possible to perform cleaning such as scraping or polishing dirt stuck to the bearing floor plate or the surface of the bearing.

The bearing cleaning tool 100 of the present embodiment is a device to be used by being attached to the electric screwdriver device 90, and is interchangeably attached to the electric screwdriver device 90.
FIG. 1 is a side view showing the bearing cleaning tool 100 attached to the electric screwdriver device 90, and FIG. 2A is a top view showing the bearing cleaning tool 100 attached to the electric screwdriver device 90.
The bearing cleaning device 100 is a cleaning device used for cleaning the bearing 2 of the bearing floor plate 1 which is assembled so as to slidably support the movable rail in the movable crossing of the turnout of the railway. It is used by attaching it to the electric driver device 90.

The bearing 2 of the bearing floor plate 1 has a sphere 3 and a frame-shaped member 4 having a circular opening 4a formed therein, and a part of the sphere 3 is exposed from the opening 4a on the upper surface of the bearing floor plate 1. The sphere 3 is held rotatably (see FIGS. 5 to 7).

As shown in FIGS. 1 and 2 (a) and 2 (b), the bearing cleaning device 100 includes a long first rotating shaft 10 that is attached to the electric driver device 90 and rotates, and a first rotating shaft 10. A second rotating shaft 20 connected to the tip side, a roller 30 attached to the second rotating shaft 20, and a base end portion 41 extending along the first rotating shaft 10 are electric drivers. It includes a posture stabilizing member 40 which is attached to the device 90 and whose tip end portion 42 is arranged so as to be located in the vicinity of the roller 30.

The electric screwdriver device 90 includes a motor drive unit (not shown), a power supply unit (not shown), and the like, and is a well-known device that rotates a rotation shaft fixed to the chuck portion 91 around its axis.
For example, the electric screwdriver device 90 is a machine tool capable of rotating a driver bit or a drill bit fixed to the chuck portion 91 to screw or drill a hole.

The first rotating shaft 10 is a shaft member whose one end 11 is fixed to the chuck portion 91 of the electric screwdriver device 90 and is rotated, and a cap gear 13 is arranged at the tip of the other end 12.
The second rotating shaft 20 is a shaft member assembled in a direction intersecting the first rotating shaft 10, and a cap gear 23 meshing with the cap gear 13 of the first rotating shaft 10 is arranged. Has been done. The second rotating shaft 20 of the present embodiment is assembled in a direction orthogonal to the first rotating shaft 10.
Then, the rotational force of the first rotating shaft 10 rotated by the electric driver device 90 is transmitted to the second rotating shaft 20 via the cap gears 13 and 23 so that the second rotating shaft 20 rotates. It has become.

The roller 30 is a rotating body that is fixed to the second rotating shaft 20 and rotates integrally with the second rotating shaft 20 with the second rotating shaft 20 as the axis.
The roller 30 is a rubber member, and a plurality of convex portions 31 are provided in a staggered arrangement on the outer peripheral surface of the roller 30. In the present embodiment, for example, a silicon rubber having a hardness of 60 ° is molded to form a roller 30.

As shown in FIG. 3, a rib 32 is provided on the inner circumference of the roller 30, and a pair of wheels 33 that sandwich the rib 32 from both sides and are integrated with the roller 30 are fixedly installed. The roller 30 is fixed to the second rotating shaft 20 by tightening the hexagonal screw N fitted into the wheel 33 to the second rotating shaft 20.
By fixing the wheel 33 fixed to the roller 30 to the second rotating shaft 20, the roller 30 can rotate suitably without idling.

The convex portion 31 provided on the outer peripheral surface of the roller 30 has a substantially truncated cone shape, and as shown in FIG. 4, the convex portion 31 outside the width direction of the roller 30 is formed higher.
Further, an inclined surface 31a that descends toward the center in the width direction of the roller 30 is formed at the tip of the convex portion 31, and the inclined surface 31a of the convex portion 31 on the outer side in the width direction of the roller 30 is the axis of the roller 30. A large angle with the heart is formed.
By doing so, the tip surface of the convex portion 31 of the roller 30 can be brought into close contact with the surface of the sphere 3 of the bearing 2.
A flat surface 31b parallel to the axis of the roller 30 is formed at the tip of the convex portion 31 at the center of the roller 30 in the width direction.

As shown in FIG. 2B, the posture stabilizing member 40 is a cover member that covers the first rotating shaft 10 and the second rotating shaft 20, and the first rotating shaft 10 and the second rotating shaft 20 inside the cover member 40. The shaft 20 is rotatably supported.
The posture stabilizing member 40 is, for example, a member made of resin, and is assembled by screwing two divided and molded parts.

At the base end of the posture stabilizing member 40, a base end portion 41 for attaching the posture stabilizing member 40 to the electric driver device 90 is provided.
The base end portion 41 of the posture stabilizing member 40 is attached to the driver device main body so as to cover the chuck portion 91 of the electric driver device 90.
A window opening 41a for making the chuck portion 91 and one end 11 of the first rotating shaft 10 visible is provided on the base end portion 41 side, and the chuck portion 91 and the first portion 11a are provided from the window opening 41a. Since the rotating shaft 10 of the above can be touched, it is easy to attach the first rotating shaft 10 to the chuck portion 91 of the electric screwdriver device 90.

At the tip of the posture stabilizing member 40, a tip portion 42 having a shape that exposes one side surface of the roller 30 and the outer peripheral surface of the tip side of the roller 30 is provided. That is, the tip portion 42 has a shape that surrounds the other side surface of the roller 30 and the outer peripheral surface other than the tip end side.
Three protrusions 43 are provided at a portion of the tip 42 of the posture stabilizing member 40 where the outer peripheral surface of the roller 30 is exposed.
The three protrusions 43 are formed so as to correspond to the surface shape of the frame-shaped member 4 of the bearing 2, and when they come into contact with the frame-shaped member 4 of the bearing 2, they come into contact with each other by a line or a surface instead of a point. It can be widely contacted (see FIGS. 5 to 7).
Of the three protrusions 43, the two protrusions 43 on both sides have flexibility.

If the bearing cleaning tool 100 having such a configuration is attached to the electric screwdriver device 90 and used, the roller 30 of the bearing cleaning tool 100 can be rotated at high speed by operating the electric screwdriver device 90.

Then, when the bearing 2 of the bearing floor plate 1 is cleaned by using the bearing cleaning device 100 attached to the electric driver device 90, the posture stabilizing member 40 is substantially perpendicular to the bearing floor plate 1 as shown in FIGS. 5 to 7. The protrusion 43 of the posture stabilizing member 40 is brought into contact with the frame-shaped member 4 of the bearing 2 and the roller 30 is brought into contact with the sphere 3 of the bearing 2 so as to abut against each other.
In this state, the electric screwdriver device 90 is operated to rotate the roller 30 of the bearing cleaning tool 100 at high speed, thereby forcibly rotating the sphere 3 of the bearing 2.

If the rubber roller 30 is rotated at high speed in a state where it is in contact with the sphere 3 of the bearing 2, even the sphere 3 which was difficult to rotate manually due to clogging or the like can be rotated. The sphere 3 that has been forcibly rotated can scrape out the dirt that has been stuck inside the bearing.
In particular, since a plurality of convex portions 31 are provided on the outer peripheral surface of the roller 30, the sphere 3 of the bearing 2 can be firmly gripped and rotated.
Further, since the convex portion 31 of the roller 30 has a substantially truncated cone shape, the grip force is strong and the roller 30 is less likely to be damaged such as broken.

Here, with the roller 30 rotated by the electric screwdriver device 90 in contact with the sphere 3 of the bearing 2, the protrusion 43 of the tip 42 of the posture stabilizing member 40 is brought into contact with the frame-shaped member 4 of the bearing 2. As a result, the displacement of the roller 30 with respect to the bearing 2 is regulated, and the roller 30 can preferably rotate the sphere 3 of the bearing 2.
That is, if the roller 30 rotated at high speed is only brought into contact with the bearing 2 (sphere 3), the roller 30 is likely to be displaced from the bearing 2 due to the reaction of the rotational force, and it is difficult to keep the roller 30 in contact with the bearing 2. However, with the roller 30 in contact with the bearing 2, the tip portion 42 (protrusion portion 43) of the posture stabilizing member 40 is brought into contact with the bearing 2 to regulate the misalignment of the roller 30 and achieve high speed. It allows the rotating roller 30 to continue to contact the bearing 2.

Further, since the two protrusions 43 on both sides of the three protrusions 43 of the tip 42 of the posture stabilizing member 40 have flexibility, the degree of adhesion between the roller 30 and the sphere 3 can be finely adjusted. it can.
Specifically, the posture stabilizing member is such that at least one of the three protrusions 43 is elastically deformed rather than the three protrusions 43 being brought into contact with the frame-shaped member 4 of the bearing 2. The roller 30 and the sphere 3 can be brought into close contact with each other when the tip 42 of the 40 is strongly pressed against the bearing 2.
When the roller 30 and the sphere 3 are brought into close contact with each other, the rotational force of the roller 30 can be easily transmitted to the sphere 3. Therefore, when the roller 30 is difficult to rotate, the degree of adhesion between the roller 30 and the sphere 3 is increased in this way. It should be adjusted as follows.

In this way, if the bearing cleaning tool 100 of the present embodiment is attached to the electric driver device 90 and used, the sphere 3 of the bearing 2 can be forcibly rotated by the roller 30 that rotates at high speed, and the sphere 3 of the bearing 2 is forcibly rotated. It is possible to perform cleaning by scraping out the dirt that has been clogged and stuck inside the bearing 2 by the formed sphere 3.
When the sphere 3 of the bearing 2 is forcibly rotated by the roller 30 that rotates at high speed, if the lubricant spray is sprayed toward the bearing 2, the sphere 3 is rotated more smoothly and efficiently. Dirt can be scraped out.

The present invention is not limited to the above embodiment.
The bearing cleaning tool 100 of the present embodiment includes, for example, as shown in FIG. 8, a roller type brush 50 that can be replaced with a roller 30 attached to the second rotating shaft 20. The roller 30 and the roller type brush 50 can be easily replaced by removing and attaching the hexagonal screw N.
The roller type brush 50 is a columnar brush in which the tips of the stainless steel bristle material implanted on the center side are directed toward the outer peripheral side of the brush.
If the bearing cleaning tool 100 replaced with the roller type brush 50 is attached to the electric screwdriver device 90 and used, dirt stuck to the surfaces of the bearing floor plate 1 and the bearing 2 can be scraped off.
As described above, in the bearing cleaning tool 100 of the present embodiment, the roller 30 and the roller type brush 50 can be easily replaced, so that the bearing cleaning tool 100 can be replaced according to the cleaning application to perform suitable cleaning.

In the above embodiment, the case where the roller 30 and the roller type brush 50 are replaced and used as the rotating body attached to the second rotating shaft 20 of the bearing cleaning tool 100 has been described as an example, but the present invention has been described. It is not limited to this.
For example, by removing the bearing cleaning device 100 from the electric driver device 90 and using a disk-shaped brush (so-called polisher brush) that rotates integrally with the shaft fixed to the chuck portion 91 of the electric driver device 90, the bearing floor plate 1 or Cleaning may be performed to scrape off the dirt stuck to the surface of the bearing 2.
In the case of a polisher brush for cleaning the bearing floor plate 1 and the bearing 2, it is preferable that the rotating shaft is long and the diameter of the disk-shaped brush is small. By doing so, even in a narrow part of the rail, the bearing floor plate 1 and the bearing 2 can be cleaned as if they were polished.

Further, in the above embodiment, the convex portion 31 on the outer peripheral surface of the roller 30 is formed so as to be higher toward the outer side in the width direction of the roller 30, but the present invention is not limited to this.
For example, the outer peripheral surface of the roller 30 is formed on a curved surface so that the central side in the width direction is recessed, a convex portion 31 having the same height is formed on the curved surface, and the outer surface of the roller 30 in the width direction is from the center of the roller. The position of the tip may be raised.

In addition, it goes without saying that the specific detailed structure and the like can be changed as appropriate.
