Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball receiving support method and ball receiving floor plate device for a tongrel in a railway rolling mill.
[0002]
[Prior art]
Conventionally, in a rolling mill, a floor board is arranged on a sleeper, and one side edge of the bottom of the basic rail is engaged with the floor board, and the other side edge is engaged and pressed with a bolt, a nut and an engaging washer to the sleeper. It is stuck. Next, the Tongleil has a required length along the basic rail, and its bottom surface is in contact with the floor plate, and is slidably installed with plenty of sliding oil interposed therebetween.
[0003]
[Problem to be Solved by the Invention]
As explained in the above description of the prior art, the Tongrel is placed in contact with the floor plate, slidable oil is slidable, so that the Tongrel moves horizontally and moves up and down. It did not go up and down. However, when the tongue is supported by the ball bearing proposed in the present invention, the vertex of the ball bearing comes into contact with the bottom surface of the tongue glaze to make point contact. Therefore, it is necessary to prevent the Tongrel from coming into contact with the floor board. In addition, when the ball receivers are arranged in the moving direction of the Tongleil, the outer diameter constituted by the diameter of the ball, the diameter of the seat that supports the ball, and the casing that accommodates them is formed between the apexes of the ball receivers. Therefore, it is separated.
[0004]
So, when the Tongrel rides on the first ball receiver, it rises by its height and is supported in point contact with one of the first ball bearings until it reaches the next second ball bearing. The Tongleil is upset around its apex. Then, after getting on the next second ball bearing and moving away from the first ball bearing, it is supported by the point contact again with one ball bearing, causing the same shaking, and then moving to the third ball bearing. It is what is done. In this way, with one ball receiver, fluctuation cannot be avoided, and therefore a swinging phenomenon occurs.
The present invention has been made for the purpose of eliminating such fluctuation of the Tongrel.

【The invention's effect】
Conventionally, as a result of research, it has been found that in a ball receiving device that supports a Tongrel by a ball arranged on a floor plate, the ball of the ball receiving device should be made as large as possible due to the weight of the bearing. However, when the ball diameter is increased, the distance between the vertices of the ball receiving device increases, and the connecting surface of the Tongleil cannot reach two points of the ball receiving device, and the vertices move up and down the vertices. I couldn't slide.
However, according to the device of the present invention, since the tongrel slide direction and the transverse direction are arranged in the vertical direction and the horizontal direction, even if the ball of the ball receiving device has a large diameter, Thus, the diameter of the ball receiving device can be made smaller than the diameter of the ball, and two or more points can always be connected to the connecting surface of the Tongrel.
Therefore, compared with the conventional floor board, slide resistance is reduced significantly and it can slide smoothly, without shaking.
