JPH09273103A - Bearing method of ball of tongue rail in railroad switch and ball-bearing floor board device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To improve the sliding capacity, by arranging bearing balls to make two or more rows in the sliding direction of a tongue rail and arranging the top at a specified position. SOLUTION: A basic rail 3 is fixed to a floor board 1 fixed to a sleeper 2 and a tongue rail 4 is laid so as to freely slide. And bearing balls 12a-12e are arranged at the outside of the rail 4. In this time, the bearing balls 12a-12c of the first row and the bearing balls 12d-12e of the second row are vertically arranged in the sliding direction through a specified distance and also arranged separately in the breadthwise direction so that the tracks of the top against the rail discord from each other. The tops of the second row are arranged at the middle of the adjacent tops of the first row. In this way, even when large diameter balls are used, the distance between tops in the sliding direction can be made shorter than the ball diameter and the balls can be always connected to the tongue rail face at two or more points and the slide resistance can be remarkably reduced. And further, the tongue rail can be smoothly slid without swinging.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball bearing support method and a ball bearing plate device for a tongue rail in a railway switch.

[0002]

2. Description of the Related Art Conventionally, in a switching machine, a floor board is arranged on a sleeper, one side edge of a bottom portion of a basic rail is engaged with the floor board, and the other side edge is engaged with a bolt / nut and an engagement washer. Pressed and stuck to the sleepers. Next is Tongleir
The bottom surface of the base rail is supported in contact with the floor plate for a required length along the base rail, and a sufficient amount of sliding oil is interposed between the base rail and the base rail so as to be slidable.

[0003]

As described in the section of the description of the prior art described above, since the tongue rail has its bottom surface in contact with the floor plate and is installed slidably via the lubricating oil, The rail moved horizontally and never went up or down. However, if the tongue rail is supported by the ball receiver proposed in this invention, the apex of the ball receiver comes into point contact with the bottom surface of the tongue rail, so that the required height of the apex of the ball receiver is increased with respect to the floor plate. It is necessary to prevent the tongue rail from touching the floorboard. Also, when the ball bearings are arranged in the direction of movement of the tongle rail, the outer diameter formed by the diameter of the ball, the diameter of the seat that supports the ball, and the casing that accommodates them is between the tops of the ball bearings. Therefore, they will be separated.

Then, when the tongue rail rides on the first ball receiver, it rises by that height and then comes into point contact with one of the first ball receivers until it reaches the next second ball receiver. It is only supported by, and the tongue rail is agitated around its apex. Then, when riding on the second ball bearing and then leaving from the first ball bearing, the ball bearing again comes into point contact with one ball bearing and is swayed in the same manner, and then it moves and is supported by the third ball bearing. It is what is done. In this way, with a single ball receiver, shaking cannot be avoided, and therefore a swinging phenomenon occurs. The present invention has been made for the purpose of eliminating the fluctuation of the tongue rail.

[0005]

[Means for Solving the Problem] The apex of the ball receiver in the ball receiving and supporting portion for the tongue rail slide is vertically arranged in the slide direction of the tongue rail at a required interval and is separated in the horizontal direction by two rows.

There is a method of bearing the ball of the Tonguerail on the railway switch.

[0006] The vertices of the ball receivers in the tongue rail slide ball bearing support portion are arranged in a row at a required interval in the sliding direction of the tongue rails and at a required width in a horizontal direction.
It is characterized in that the rows of the vertices are arranged in columns so that the loci of the vertices do not coincide with each other in the vertical direction, and the vertices of the second row are arranged in the middle of the vertices adjacent to each other in the vertical direction of the first row. There is a tongue rail ball bearing plate device in a railway switch.

The fixing of the basic rail is continuous with an engaging edge engaging with one side edge of the bottom portion of the basic rail at the inner edge toward one end, and a slanting engaging groove outward and further with the engaging edge. Then, the front side of the oblique engaging groove is recessed to provide a basic rail fixing support portion, and a vertically tightening bolt support hole is provided between the oblique side engaging groove and the basic rail fixing support portion. In addition, a tongue rail connecting bearing part that supports the tongue rail is formed in the central part that is continuous with the base rail fixing bearing part, and then the tongue rail connecting ball bearing is continuously connected to the tongue rail connecting bearing part to the opposite outer side. A bearing may be provided.

[0020]

As a result of research, it has been found that, in the conventional ball bearing device which supports the tongue rails by the balls arranged on the floor plate, it is preferable that the ball of the ball bearing device has a diameter as large as possible in view of bearing weight. However, if you increase the diameter of the ball,
The distance between the vertices of the ball receiving device became large, and the connecting surface of the tongue rail could not reach the two points of the ball receiving device. However, according to the device of the present invention, since the tongue rails are arranged in the vertical and horizontal directions in the sliding direction and the transverse direction, the ball receiving device has a large diameter. The diameter of the ball forming the space between the vertices of the ball receiving device can be made smaller, and two or more points can always be connected to the connecting surface of the tongue rail. Therefore, the sliding resistance is greatly reduced as compared with the conventional floorboard, and the sliding can be smoothly performed without shaking.
