Abstract
A bearing box for a rotating roller for supporting or transporting a high-temperature object. The bearing box includes a bearing and seal units disposed therein. A cooling jacket is disposed at an outer periphery of the bearing box so that the cooling jacket covers at least a portion of an axial region of the bearing and at least a portion of an axial region of the seal unit. The cooling jacket has a cooling water inlet and a cooling water outlet, and the bearing box is cooled by cooling water supplied to the cooling jacket through the cooling water inlet.
Claims4
A bearing box for a rotating roller for supporting or transporting a high-temperature object, the bearing box comprising:
- a bearing and a seal unit disposed therein;
- and
- a cooling jacket having a cooling water inlet and a cooling water outlet, the cooling jacket being disposed at an outer periphery of the bearing box so that the cooling jacket covers at least a portion of an axial region of the bearing and at least a portion of an axial region of the seal unit,
- wherein the bearing box is cooled by cooling water supplied to the cooling jacket through the cooling water inlet, and
- wherein a portion of an outer periphery of the cooling jacket disposed at an outer periphery of the axial region of the seal unit is at least partially disposed on a radially inner side of a portion of an outer periphery of the cooling jacket disposed at an outer periphery of the axial region of the bearing.
A method for cooling a bearing box for a rotating roller for supporting or transporting a high-temperature object, the bearing box comprising a bearing and a seal unit disposed therein, the method comprising:
- placing a cooling jacket at an outer periphery of the bearing box so that the cooling jacket covers at least a portion of an axial region of the bearing and at least a portion of an axial region of the seal unit;
- cooling the bearing box by introducing cooling water into the cooling jacket through a cooling water inlet provided in the cooling jacket;
- and
- discharging the cooling water that has cooled the bearing box through a cooling water outlet provided in the cooling jacket,
- wherein a portion of an outer periphery of the cooling jacket disposed at an outer periphery of the axial region of the seal unit is at least partially disposed on a radially inner side of a portion of an outer periphery of the cooling jacket disposed at an outer periphery of the axial region of the bearing.
