Description

Bearing stripping device {BEARING STRIPPING DEVICE}

The present invention relates to a bearing removal device.

More particularly, the present invention relates to a bearing removing device that allows the first cylinder of the removing unit to push the shaft of the motor in a state where the bearing is fixed by the second cylinder of the fixing unit, thereby allowing the bearing to be removed from the motor.

In general, a driving device for driving a mechanical device includes a motor for generating a driving force and a power transmission mechanism for transmitting a driving force generated from the motor.

Such a motor is configured to drive a driving facility by receiving electric power to generate rotational force and transmitting the rotational force through a power transmission mechanism.

At this time, the shaft of the motor rotated by the rotational force of the motor can be supported by the bearing so that the rotation is made smoothly, the bearing supports the weight of the shaft and the load on the shaft while fixing the rotating shaft in a certain position While rotating the shaft.

The shaft is inserted into and fixed to the inner diameter of the bearing, and fixing the shaft to the inner diameter of the bearing typically uses a shrink fit method using interference fit or thermal expansion.

The thermal expansion and shrinkage method is a method of heating the bearing to expand the inner diameter and inserting the shaft into the expanded inner diameter and then gradually cooling the bearing. And fix the shaft to the inner diameter.

These bearings are worn when the load is repeatedly applied by the shaft, and the fatigue strength increases, so that the bearings need to be replaced. In particular, the bearings are provided in a bearing or a vehicle used in a rolling facility of a steel mill producing steel products. Since the bearings used for the motor have a very large load on the shaft and the bearings, the repair and replacement of the bearings is frequently performed.

As one of the techniques for solving this problem, Korean Utility Model Publication No. 20-2009-0011109 discloses a bearing removing device.

(1) shows a state in which the bearing (3) removed from the fixed groove 220 falls in the downward direction, Figure 5e is the supply rail (830) controlled by the control unit 700 is driven to the bearing (3) ) Is not removed, the other motor (1) is adjacent to the removal unit 200 Shows a state that moved to the position.

That is, in the bearing removing device according to another embodiment of the present invention, the fixed rod 311 slides after the bearing 3 is inserted into the fixing groove 220 by moving the motor 1 in the horizontal direction. Is moved to fix the bearing 3, and after the bearing 3 is fixed by the fixing rod 311, the stripping rod 241 is slid in the direction of the bearing 3 to move the bearing ( It is configured to push the shaft 2 of the motor 1 inserted in the inner diameter of 3), so that the bearing 3 is removed from the motor 1 and then the stripping rod 241 is removed from the bearing 3. After the slide 3 is moved in a spaced apart direction so that the bearing 3 falls in the downward direction, the supply rail 830 is driven so that the other motor 1 in which the bearing 3 is not removed is removed from the removal unit 200. Adjacent to the bearings repeatedly on the motor (1) Remove 3).

According to the present invention, the first cylinder of the removal unit is configured to push the shaft of the motor in a state in which the bearing is fixed by the second cylinder of the fixing unit, whereby the bearing is removed from the motor.

In the foregoing description, various embodiments of the present invention have been described and described. However, the present invention is not necessarily limited thereto, and a person having ordinary skill in the art to which the present invention pertains may have various modifications without departing from the technical spirit of the present invention. It will be appreciated that branch substitutions, modifications and variations are possible.
