Description

Dismounting device for drum core bearing

Technical Field

The utility model belongs to the technical field of the equipment maintenance, more specifically, the utility model relates to a dismounting device for drum core bearing.

Background

At present, finish or because of the damaged back of external factor drum core when warming mill such as warming mill and sensitization drum, this accessory just can't normal use, and it is higher to change one set of assembly cost, changes the drum core comparatively costsly alone, but, the biggest problem of changing the drum core is exactly that the fixed bearing in drum core both ends is difficult for taking off, sometimes can injure its accessory and bearing smoothness itself by mistake, and improper operation is spent in selenium drum stand or hot-rolling mill assembly just can not be used.

SUMMERY OF THE UTILITY MODEL

A primary object of the utility model is to provide a dismounting device for drum core bearing to solve among the prior art inconvenient problem of drum core bearing dismantlement.

In order to achieve the above object, the utility model provides a dismounting device for drum core bearing, including the body, the first end of body is the link, and the second end of body is the operation end, and the link joint is on the drum core, and with the bearing side butt, operation end and screw rod threaded connection, the one end of screw rod and the terminal surface butt of drum core.

Further, the body is made by the channel-section steel, offers the recess on the lateral wall of channel-section steel, offers the screw hole on the other lateral wall, and the recess joint is on the drum core, and the bearing butt is in the inboard of recess, screw hole and screw rod threaded connection.

Furthermore, the inner end of the screw rod is welded with a gasket, and the gasket is abutted to the end face of the drum core.

Further, the diameter of the spacer is equal to the diameter of the drum core.

Furthermore, two handles are welded at the outer end of the screw rod and symmetrically arranged on two sides of the screw rod.

Further, a reinforcing plate is arranged between the connecting end and the operating end.

Use the technical scheme of the utility model, drive the screw rod through rotatory handle and rotate, loosen from the drum core until the bearing and take off, realize the dismantlement to the bearing. The device has simple integral structure and convenient operation, greatly reduces the labor intensity of workers for disassembling the drum core bearing, and improves the working efficiency.

Drawings

The accompanying drawings, which form a part of the present application, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the invention and not to limit the invention. In the drawings:

fig. 1 shows a schematic structural view of a dismounting device according to an embodiment of the present invention;

fig. 2 shows a schematic cross-sectional structure of fig. 1.

Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present invention, unless stated to the contrary, directional terms such as "upper, lower, top, bottom" are used with respect to the orientation shown in the drawings, or with respect to itself in the vertical, perpendicular, or gravitational direction; likewise, for ease of understanding and description, "inner and outer" are inner and outer relative to the profile of the components themselves, but the above directional terms are not intended to limit the invention.

In order to solve the inconvenient problem of drum core bearing dismantlement among the prior art, the utility model provides a dismounting device for drum core bearing.

As shown in fig. 1 and 2, the dismounting device for the drum core bearing comprises a body 10, a first end of the body 10 is a connecting end 11, a second end of the body 10 is an operating end 12, the connecting end 11 is connected to the drum core 20 in a clamping manner and is abutted against the side surface of a bearing 21, the operating end 12 is in threaded connection with a screw 15, and one end of the screw 15 is abutted against the end surface of the drum core 20.

By applying the technical scheme of the embodiment, the handle 16 is rotated to drive the screw 15 to rotate until the bearing 21 is loosened from the drum core 20, so that the bearing 21 is detached. The device has simple integral structure and convenient operation, greatly reduces the labor intensity of workers for disassembling the drum core bearing, and improves the working efficiency.

In this embodiment, the bearing 21 is sleeved on the drum core 20 and is in interference fit with the drum core 20, the connecting end 11 is located outside the bearing 21 and is clamped on the drum core 20, the connecting end 11 plays a role in positioning, when the screw 15 rotates, a pressure effect is exerted on the end of the drum core 20, and since the drum core 20 is kept stationary, the connecting end 11 generates an outward thrust to the bearing 21 and drives the bearing 21 to move outward together until the bearing 21 is loosened from the drum core 20.

In this embodiment, the body 10 is made by the channel-section steel, set up recess 13 on the lateral wall of channel-section steel, set up screw hole 14 on the other lateral wall, recess 13 joint is on drum core 20, bearing 21 butt is in the inboard of recess 13, screw hole 14 and screw rod 15 threaded connection, the inner welding of screw rod 15 has gasket 17, gasket 17 and the terminal surface butt of drum core 20, and the diameter of gasket 17 equals the diameter of drum core 20, for convenient operation, it has two handles 16 to weld in the outer end of screw rod 15, two handles 16 symmetry set up the both sides at screw rod 15, in order to increase overall structure's stability, be provided with reinforcing plate 18 between link 11 and operation end 12.

During the use, establish notched lateral wall joint on the drum core with the channel-section steel to let the bearing be located the inboard of channel-section steel, make the side butt of establishing notched lateral wall and bearing, then rotatory handle makes the gasket and the terminal surface butt of drum core, continues to rotate the handle, loosens from the drum core until the bearing and takes off, accomplishes the dismantlement work of bearing promptly.

From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: the problem of inconvenient dismantlement of drum core bearing among the prior art has effectively been solved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
