Description

Bearing block with cooling means

The present invention relates to a bearing block, and more particularly, to a bearing block having a cooling means therein, which can prevent damage to a bearing in a high temperature environment and extend its life.

Cast steel continuously produced in the continuous casting process, which is one of the steelmaking processes, is transferred to a rolling process using a roll. In this process, the casting is prevented from cooling and the temperature of the cast steel is rolled to a temperature (1,200 ° C.). An electric induction heater is installed between the rolls so that it can be maintained to heat the slabs.

The rolls installed between these heaters are driven at high temperatures, and high heat is transferred to the bearings mounted at both ends of the rolls. The high heat causes deterioration and fixation of the grease manually injected into the bearing block, which prevents smooth lubrication. Therefore, the rotation of the roll is stopped, causing problems such as deterioration of product quality and productivity, implementation of facility repair work, and the like.

In order to solve this problem, when grease is supplied using a pump of a centralized oil supply system, grease is injected into each bearing by a distribution valve, but the ambient temperature is so high that the effect is insignificant. In addition, in this method, when the portion to be supplied by the grease supply method at room temperature is a high temperature, the concentrated oil supply device loses its role due to grease sticking in the grease supply line. Therefore, the grease forced oil supply to the bearing is interrupted, and the grease already supplied in the bearing housing deteriorates and sticks, the viscosity drops, and the bearing is broken, and the roll is not driven. As a result, it is desirable to keep the temperatures of the bearings and bearing blocks low in order to obtain a smooth function of the bearings.

Accordingly, an object of the present invention is to provide a bearing block capable of continually obtaining a function of a bearing by configuring a cooling means in a bearing block, in order to solve the above-mentioned problems appearing under a high temperature environment.

The present invention for solving the above object is formed in the central portion is formed with a through-hole receiving the bearing, the outer front surface is formed with a groove and the through holes connected to both ends of the groove formed on both sides of the lower front, A liner is inserted into a groove formed on the surface of the main body, and a groove is formed on the outer surface of the front surface, and both ends of the front side have a through hole communicating with both ends of the groove and through holes formed in the main body. And a cover attached to the outer surface of the liner to fix the groove formed on the surface of the liner to form a closed passage. Cooling effect on the bearing can be obtained by discharging to the outside through the through hole formed on the other side. .

In addition, in the present invention, the grease supplied to the bearing is provided by placing the grease supply pipe for supplying the grease to the bearing located in the penetrating portion of the main body constituting the bearing block in the coolant pipe having a larger diameter and then supplying and flowing the coolant to the coolant pipe. Can be cooled.

Hereinafter, with reference to the accompanying drawings of the present invention will be described in detail.

1 is a perspective view of a roll mounted to the present invention, Figure 2 is an exploded perspective view of Figure 1, the bearing block 10 according to the present invention is composed of a body 11, a liner 12 and a cover 13.

11A of bearings are formed in the center part of the main body 11, The groove 11B of the form which encloses the penetrating part 11A is formed in the outer front surface. Through-holes 11C and 11D connected to both ends of the above-described groove 11B are formed at both sides of the lower end of the front part of the main body 11, respectively.

The liner 12 is completely inserted into the groove 11B formed on the surface of the main body 11, and the groove 12A for flowing the coolant is formed on the entire outer surface of the liner 12. As shown in FIG. In addition, through-holes 12C and 12D connected to both ends of the above-described groove 12A are formed at both sides of the lower end of the liner 12, respectively. When the main body 11 and the liner 12 are coupled, the through holes 11C and 11D formed in the main body 11 and the through holes 12C and 12D formed in the liner 12 coincide with each other. The liner 12 is preferably formed of a material with high thermal conductivity, for example copper.

The cover 13 having the same shape as the liner 12 is attached and fixed to the outer surface of the liner 12, and the groove 12A formed on the surface of the liner 12 when the cover 13 and the liner 12 are attached to each other. The cover 13 forms a closed passage. A method of fixing the above-described liner 12 to the main body 11 is described below. The main body 11 and the liner 12 are completely adhered and fixed by pressing the liner 12 with the cover 13 and then welding the liner 12 to the main body 11 by cooling the liner 12.

The through-holes 11C and 11D formed at both sides of the lower part of the front part of the main body 11 respectively have a coolant inlet 11E for introducing coolant and an outlet 11F for withdrawing the cooled coolant to the outside. Is inserted.

On the other hand, a bearing (not shown) is accommodated in the penetrating portion 11A formed in the central portion of the main body 11, and one end R1 of the roll R is located in the bearing. Reference numerals 14 and 14A denote bearing covers to seal both sides of the bearing block 10 in which the bearings R and the ends R1 of the rolls are accommodated, 15 and 15A denote labyrince as sealing devices, and 16 denote couplings (labyrinse). And the configuration and function of the coupling is general, a detailed description thereof will be omitted).

When explaining the function of the present invention as described above with reference to Figures 3 and 4, Figure 3 is a front sectional view of the present invention, Figure 4 is a side cross-sectional view of the present invention, inserted into the groove 11B of the main body 11, fixed Between the liner 12 and the cover 13 is formed a groove 12B formed on the outer surface of the liner 12 and a cooling water passage formed by the cover 13 (for reference, 11B for convenience). Both ends of the passage 11B are connected to the coolant inlets and outlets 11E and 11F respectively inserted into the through holes 11C and 11D of the lower side of the front portion of the main body 11.

Therefore, the coolant introduced through the inlet 11E flows along the coolant passage 12B between the liner 12 and the cover 13 and is discharged to the outside through the outlet 11F. As a result, when the bearing is rotated in the bearing block 10 (i.e., when the roll R is rotated), the bearing heated by the surrounding environment is caused by the coolant continuously flowing in the aforementioned coolant passage 12B. The effect of cooling is obtained. In particular, the liner 12 inserted and fixed in the groove 11B of the main body 11 is made of copper having excellent heat transfer effect, so that the heat of the main body 11 can be easily transferred to the coolant to double the cooling effect.

5 is a perspective view of the present invention having grease cooling means, which further shows the present invention further comprising cooling means 20 for cooling the grease supplied to each bearing block 10. As described above, when grease is supplied using a pump of the centralized oil supply device, grease is injected into each bearing by the distribution valve 21. In the present invention, the grease supply pipe 23 connected to the distribution valve 21 is accommodated in the cooling water pipe 22 having a larger diameter, and the cooling water pipe 22 is supplied by supplying and flowing the cooling water to the cooling water pipe 22. The grease flowing in the grease supply pipe 23 located therein can be cooled. Therefore, it is possible to prevent the sticking of the grease and the decrease of viscosity due to the surrounding high heat.

The present invention as described above can form a cooling passage in which the coolant is circulated in the bearing block to cool the bearing at a high temperature, thereby improving the efficiency of the equipment. There is an effect that can be obtained.
