Abstract
The utility model discloses a kind of hearth roll being provided with heat insulation structural, comprise roller, be fixedly connected on the roller head at roller two ends; The cavity that outer end is closed is provided with in roller head; Cavity is provided with in roller; Roller head is provided with taper roll neck in centre; Further improvement is: roller cavity two ends and roller head junction are provided with dividing plate; Dividing plate, by airtight for roller head internal cavity, formed and closes insulated cavity, filling with insulation material in this closed insulated cavity, forms heat insulation structural.The utility model roller header structure stress is little, significantly reduces by the thermal heat transfer capability of roller to roll shaft, obviously improves bearing working condition.
Description
Technical field
The utility model relates to Equipment for Heating Processing, particularly relates to a kind of hearth roll.
Background technology
Hearth roll is located in solution heat treatment furnace for transmitting the steel bar plate of heat-treating; Existing hearth roll generally comprises roller, is connected to the roller head at roller two ends.Roller head is generally multidiameter structure, with roller junction external diameter and roller basically identical, install bearing place external diameter less, that is axially each section of different diameters is comparatively large for roller head, easily produces larger stress and concentrates.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes a kind of hearth roll being provided with heat insulation structural that significantly can reduce roller head stress and concentrate.
The utility model is achieved through the following technical solutions technical goal.
Be provided with the hearth roll of heat insulation structural, comprise roller, be fixedly connected on the roller head at roller two ends; The cavity that outer end is closed is provided with in described roller head; Cavity is provided with in described roller; Its improvements are: described roller head is provided with taper roll neck in centre.
In said structure, described roller cavity two ends and roller head junction are provided with dividing plate; Described dividing plate, by airtight for roller head internal cavity, formed and closes insulated cavity, filling with insulation material in this closed insulated cavity, forms heat insulation structural.
The utility model compared with prior art, has following good effect:
1. roller head is provided with taper roll neck in centre, and the axial each section of diameter of roller head is gradually changed, and the stress significantly reducing roller head is concentrated.
2. be provided with heat insulation structural in the cavity in roll neck, significantly reduce by the thermal heat transfer capability of roller to roller head, bearing working condition is obviously improved.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below with reference to the accompanying drawings and the utility model is described in further detail in conjunction with the embodiments.
Be provided with the hearth roll of heat insulation structural, comprise roller 5, be fixedly connected on the roller head 1 at roller 5 two ends shown in accompanying drawing; The cavity that outer end is closed is provided with in roller head 1; Cavity is provided with in roller 5; Roller head 1 is provided with taper roll neck 1.1 in centre.
Roller 5 cavity two ends and roller head 1 junction are provided with dividing plate 2; Dividing plate 2, by airtight for roller head 1 internal cavity, formed and closes insulated cavity, filling with insulation material 6 in this closed insulated cavity, forms heat insulation structural.
