Description

Rolling mill bearing bush structure

Technical Field

The utility model relates to a rolling mill axle bush structure belongs to metallurgical industry steel rolling production facility technical field.

Background

The bearing bush is an important spare part in a rolling mill, the stability of a roller is an important factor for ensuring the smooth production in the steel rolling process, the roller diameter of the roller is not well cooled, the temperature is increased, the abrasion of the bearing bush is accelerated, and the conditions of burning the bearing bush, sticking iron in the roller diameter of the roller, even breaking the roller diameter and the like occur in serious cases. The rolling mill axle bush is generally the resin bakelite tile, when the resin bakelite tile wearing and tearing reach a certain degree, causes the clearance too big, compels to change the axle bush, increases spare parts cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a rolling mill axle bush structure, the cooling effect is good, and wearing and tearing are little, solve the problem that exists among the background art.

The technical scheme of the utility model is that:

the utility model provides a rolling mill axle bush structure which characterized in that: the bearing bush is a resin bakelite bush, the section of the bearing bush is semicircular and matched with the diameter of a roller, two water storage tanks which are arranged in a crossed manner are arranged on the inner surface of the bearing bush, which is in contact with the diameter of the roller, the bearing bush is fixed on the bush seat, and a groove matched with the bearing bush is arranged on the bush seat.

The two water storage tanks which are arranged in a crossed manner on the inner surface of the bearing bush, which is in contact with the diameter of the roller, are in a cross shape.

The two water storage tanks which are arranged in a crossed manner along the diagonal line of the bearing bush.

The two water storage tanks which are arranged in a crossed manner are U-shaped tanks.

Adopt the utility model discloses, at the steel rolling in-process, through setting up two cross arrangement's on the axle bush aqua storage tank, increase cooling water flow, utilize the heat exchange of roll and axle bush to reduce the temperature of roll and axle bush, reduced the wearing and tearing of axle bush.

The utility model has the advantages that: the cooling effect is good, the temperature of the roller and the bearing bush is reduced, and the abrasion of the bearing bush is reduced. The service cycle of the bearing bush is prolonged, the consumption of ton steel bakelite bush is reduced by 0.02kg, the purchase cost of spare parts is reduced, the bush burning phenomenon is avoided, and the smooth production is ensured.

Drawings

FIG. 1 is a front view of the present invention;

fig. 2 is a top view of the present invention;

FIG. 3 is a schematic view of the usage state of the present invention;

in the figure: the bearing bush comprises a bearing bush 1, a water storage tank 2, a bush seat 3 and a roller 4.

Detailed Description

The invention will be further explained by way of example with reference to the accompanying drawings.

Referring to the attached drawings 1-3, the rolling mill bearing bush structure comprises a bearing bush 1, water storage tanks 2 and a bush seat 3, wherein the bearing bush 1 is a resin bakelite bush, the section of the bearing bush 1 is in a semicircular shape matched with the diameter of a roller, the inner surface of the bearing bush 1, which is in contact with the diameter of the roller, is provided with the two water storage tanks 2 which are arranged in a crossed manner, the bearing bush 1 is fixed on the bush seat 3, and the bush seat 3 is provided with a groove matched with the bearing bush 1.

The specific embodiment is as follows:

in this embodiment, referring to fig. 1, 2 and 3, the bearing bush 1 is a resin bakelite bush, the surface of the bearing bush 1 contacting with the roll diameter of the roll is the inner surface of the bearing bush 1, the cross section of the inner surface is a semi-circle matching with the roll diameter of the roll, the water storage tank 2 is a U-shaped tank, and two water storage tanks 2 arranged in a cross manner are arranged on the inner surface of the bearing bush 1 along the diagonal line of the bearing bush 1.

Referring to the attached

drawings

1, 2 and 3, the contact surface between the bearing bush 1 and the bush seat 3 is the outer surface of the bearing bush 1, the outer surfaces at the two ends of the central axis of the bearing bush 1 are arc-shaped, and the middle part of the central axis of the bearing bush is isosceles trapezoid, so that the heat dissipation of the bearing bush 1 is facilitated.
