Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flange lubricator for reducing the wear of a wheel flange on a railroad vehicle wheel due to friction with a rail.

[0002]

2. Description of the Related Art A wheel flange (19) of a railway vehicle comes into contact with a rail (20) as shown in FIG. 4 to cause friction, and wears as shown in FIG. (A) shows the amount of wear, and line (b) shows the original shape. When the wheel flange (19) is worn out, it becomes impossible to maintain a certain strength. Therefore, at present, the worn wheel flange (19) is recovered by removing the wheel surface (18) as shown in FIG. (C) shows the correction amount, and line (d) shows the shape after the correction. From FIGS. 5 and 6, it can be seen that a large amount of removal (c) is required for a small amount of wear (a). Therefore, the wear of the wheel flange (19) is a major cause of shortening the life of the wheel, which has a limited amount of cutting (c). Therefore, conventionally, in order to reduce the wear of the wheel flange (19), the wheel flange (19) is coated with a rotary flange lubricator shown in FIG. 2 or a spray oil type flange lubricator shown in FIG. Oil has been done. First, in the rotary flange oil applicator of FIG. 2, the main body A (8) is supported by the support arm A (12), and
7), which is fixed to the oil sump tank A (15) and the oil supply pipe A
They are connected at (10). Further, the oil coating wheel (4) supported by the main body A (8) by the rotating shaft (5) is provided so as to contact the wheel flange (19) at a right angle, and the contact portions rotate in the same direction. . The oil coating wheel (4) rotates with the rotation of the wheel, and the centrifugal force causes oil to come out from the periphery of the oil coating wheel (4) to apply the oil to the wheel flange (19). Next, in the fountain type flange lubricator of FIG. 3, the main body B (9) is fixed to the bogie frame (17) by the support arm B (13), and the main body B (9) is different from the oil sump tank B (16) in the oil pump ( 7) via oil supply pipe B
It is connected by (11). Further, the tip of the oil injection nozzle (6) attached to the main body B (9) is provided so as to be positioned at an appropriate distance from the wheel flange (19), and the oil pump (7) is provided from the tip of this oil injection nozzle (6). With the power of
It is adapted to apply oil to the wheel flange (19).

[0003]

These have the following drawbacks. Since the diameter of the lubrication wheel is smaller than the diameter of the wheel in the rotary flange lubricator, when the traveling speed of the vehicle increases, the revolution flange lubricator tends to rotate at a high speed, which easily causes a failure. In addition, the centrifugal force causes oil to fly around and cause dirt. The oil spray type flange lubricator did not apply oil accurately to the intended place because the direction of oil spray was bent when a turbulent air flow was generated due to cross wind or high speed running of the vehicle. The present invention has been made to solve the above drawbacks, and an object thereof is to obtain a flange lubricator for railway vehicles that is suitable for high-speed operation of vehicles and does not pollute the surroundings with oil. .

[0004]

A solid lubricant (3) is wound around a cylinder A (1), and one end of the solid lubricant (3) is two cylinders B (2) rotatable with a constant force. Scissors,
It is configured so that the solid lubricant (3) can be extruded.

[0005]

[Function] When the tip of the solid lubricant (3) is pushed out by rotating the cylinder B (2) and pressed against the rotating wheel flange (19), the solid lubricant (3) is scraped by friction and the wheel flange. A lubricant is applied to (19).

[0006]

EXAMPLES Examples of the present invention will be described below. A solid lubricant (3) such as solid lubricating oil is wound around a cylinder A (1) attached to a bogie frame (17) by a support arm C (14), and one end of the solid lubricant (3) is Two cylinders B (2) that can be intermittently rotated with a constant force are sandwiched. The solid lubricant (3) may be covered with a tube made of a solid material which also serves as a lubricant or a material softer than the wheel. The present invention has the above-described structure. When using this structure, the tip of the solid lubricant (3) is brought into contact with the wheel flange (19) at an angle close to vertical to allow the cylinder B (2) to travel when the vehicle is running. Is intermittently rotated with a constant force. Then, the tip of the solid lubricant (3) is pressed against the rotating wheel flange (19) only while the cylinder B (2) is rotating, and is scraped by friction. Then, the scraped solid lubricant (3) adheres to the wheel flange (19) to serve to apply the lubricant. The cylinder A (1) rotates when a constant force is applied so that the solid lubricant (3) does not sag.

[0007]

Since the solid lubricant is simply pressed, the lubricant can be stably applied even if the wheels rotate at high speed due to high speed operation of the vehicle. Further, since the lubricant is solid, the lubricant can be accurately applied to the intended place even when a turbulent air current is generated due to a cross wind or high speed running of the vehicle. Further, since the solid lubricant does not drip, it does not stain the surroundings.
