In industrial furnace,, furnace roller need be set in stove with raw material in tow in order to make raw material smoothly by the stove district.At present the industrial furnace furnace roller mainly contains two kinds of forms: a kind ofly be the furnace roller of no water-cooled, another kind is the furnace roller that the centre leads to cooling water.The furnace roller of two kinds of forms respectively has pluses and minuses, though the furnace roller of no water-cooled can not taken away the heat in the stove, because furnace temperature is than higher, the heat of furnace roller can pass to the bearing place, causes bearing heating, has reduced bearing service life, has increased repair rate; And the furnace roller of middle logical cooling water though overcome bearing short shortcoming in service life, because cooling water will pass body of heater, must be taken away heats a large amount of in the stove, has caused the waste of the energy.
The utility model content
The purpose of this utility model provides a kind of furnace roller, when prolonging bearing service life, reduces energy resource consumption.
For achieving the above object, the utility model provides a kind of furnace roller, comprise, the roll body of hollow and the roll shaft that is arranged at described roll body two ends, wherein, in described roll shaft, be provided be used for logical cooling medium after, to the cooling duct that the bearing that is installed in the bearing position cools off, described cooling duct extends to the bearing position vertically from the outer end of described roll shaft.
Preferably, above-mentioned furnace roller, wherein: the hollow space at described roll body is provided with baffle plate;
Between described plate washer and described roll shaft, be equipped with and be used to stop the heat-insulating material of the heat of described roll body to described roll shaft transmission.。
Preferably, above-mentioned furnace roller, wherein: described baffle plate is fixed by fixture and described roll shaft.
Preferably, above-mentioned furnace roller, wherein: described fixture is a rivet.
Preferably, above-mentioned furnace roller, wherein: be provided with the cooling medium interface in the outer end of described roll shaft.
Preferably, above-mentioned furnace roller, wherein: described cooling medium interface is the swivel joint interface.
Preferably, above-mentioned furnace roller, wherein: the roll shaft of described roll body one end is provided with the featherway that makes that described roll body can freely extend to this end;
The roll shaft of the described roll body other end is provided with the locating hole that is used for fixing roll shaft, be used to the jump ring groove the keyway of drive being installed and being used for fixing described drive.
Preferably, above-mentioned furnace roller, wherein: described roll body is the heat resisting steel material.
Compared with prior art, the beneficial effects of the utility model are:
The furnace roller of the utility model embodiment is provided with the cooling duct in roll shaft, its degree of depth like this, behind the logical cooling medium, just can be cooled off bearing in the cooling duct shortly past the bearing position, thereby prolongs the service life of bearing; Because cooling medium does not pass body of heater, can not take away the heat in the stove substantially, thereby reduce energy resource consumption.In preferred embodiment of the present utility model, also be provided with heat-insulating material in the furnace roller, the heat that stops roll body by described heat-insulating material is to the roll shaft transmission, and this has further reduced energy resource consumption.
Description of drawings

Fig. 2 is the assembling schematic diagram of the furnace roller of the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
Fig. 1 is the structural representation of the furnace roller of the utility model embodiment, and with reference to Fig. 1, described furnace roller comprises:
Roll body 1, described roll body 1 is the cylindrical of hollow;
Be arranged at first roll shaft 2 of described roll body 1 one ends, in described first roll shaft 2, be provided with first cooling duct 21, described first cooling duct 21 extends to the bearing position vertically from the outer end of described first roll shaft 2, behind the logical cooling medium, the bearing that is installed in the bearing position is cooled off in described first cooling duct 21;
Be arranged at second roll shaft 3 of described roll body 1 other end, in described second roll shaft 3, be provided with second cooling duct 31, described second cooling duct 31 extends to the bearing position vertically from the outer end of described second roll shaft 3, behind the logical cooling medium, the bearing that is installed in the bearing position is cooled off in described second cooling duct 31.
Preferably, described furnace roller also comprises:
Be placed in first heat-insulating material 13 between described first plate washer 11 and described first roll shaft 2, stop that by described first heat-insulating material 13 heat of described roll body 1 transmits to described first roll shaft 2;
Be placed in second heat-insulating material 16 between described second plate washer 14 and described second roll shaft 3, the heat that stops described roll body 1 by described second heat-insulating material 16 is to 3 transmission of described second roller.
In the present embodiment, described first fixture 12 and described second fixture 15 are rivet.
In the present embodiment, be provided with cooling medium interface 23 in the outer end of described first roll shaft 2, described cooling medium interface 23 is the swivel joint interface, is used for fixing swivel joint;
Described first roll shaft 2 is provided with featherway 22, can freely extend to this end after making described roll body 1 be heated, with anti-jamming.
In the present embodiment, be provided with cooling medium interface 35 in the outer end of described second roll shaft 3, described cooling medium interface 35 is the swivel joint interface, is used for fixing swivel joint;
Described second roll shaft 3 is provided with the locating hole 32 that is used for fixing second roll shaft 3, the jump ring groove 34 that is used to that the keyway 33 of drive is installed and is used for fixing described drive 33.
