Abstract
The utility model discloses a kind of hearth roll being provided with compound heat-insulation structure, comprise roller, the roll shaft be fixedly connected in roller two stomidium; Cavity is provided with in roller; Roll shaft is provided with taper roll neck in centre; Further improvement is: be provided with the axial blind hole communicated with outside in roll shaft; Roller cavity two ends are provided with dividing plate; Roll shaft is connected the end face of one end and spaced apart one end distance of dividing plate with roller, form a closed insulated cavity, filling with insulation material in insulated cavity, forms heat insulation structural; Roll shaft and roller junction, be provided with heat insulating coat between roll shaft outer wall and roller endoporus.The utility model roll shaft stress is concentrated little, by arranging compound heat-insulation structure, significantly reducing by the thermal heat transfer capability of roller to roll shaft, obviously improving 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 roll shaft at roller two ends.Roll shaft 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 roll shaft, 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 compound heat-insulation structure that significantly can reduce roll shaft stress and concentrate.
The utility model is achieved through the following technical solutions technical goal.
Be provided with the hearth roll of compound heat-insulation structure, comprise roller, the roll shaft be fixedly connected in roller two stomidium; Cavity is provided with in described roller; Its improvements are: described roll shaft is provided with taper roll neck in centre.
In said structure, in described roll shaft, be provided with the axial blind hole communicated with outside.
In said structure, described roller cavity two ends are provided with dividing plate; Described roll shaft is connected the end face of one end and spaced apart one end distance of dividing plate with roller, form a closed insulated cavity, filling with insulation material in described insulated cavity, forms heat insulation structural.
In said structure, described heat-barrier material is alumina silicate fibre.
In said structure, described roll shaft and roller junction, be provided with heat insulating coat between roll shaft outer wall and roller endoporus.
The utility model compared with prior art, has following good effect:
1. roll shaft is provided with taper roll neck in centre, and the axial each section of diameter of roll shaft is gradually changed, and the stress significantly reducing roll shaft is concentrated.
2. be provided with the axial blind hole communicated with outside in roll shaft, cooling medium roll shaft can be passed to and cool, without the need to by the cavity in roller, can avoid taking away a large amount of heats from roller inner chamber, reduce energy loss.
3. roller, roll shaft junction are provided with heat insulation structural, significantly reduce the heat transmission from roller to roll shaft, significantly reduce by the thermal heat transfer capability of roller to roll shaft, improve bearing working condition.
4. be provided with heat insulating coat between the roll shaft outer wall of roll shaft and roller junction and roller endoporus, reduce by the thermal heat transfer capability of roller to roll shaft further, improve bearing working condition further.
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 compound heat-insulation structure shown in accompanying drawing, comprise roller 5, the roll shaft 1 be fixedly connected in roller 5 liang of stomidiums; Cavity is provided with in roller 5; Roll shaft 1 is provided with taper roll neck in centre, is provided with the axial blind hole communicated with outside in roll shaft 1.
Roller 5 cavity two ends are provided with dividing plate 4; Roll shaft 1 is connected the end face of one end and spaced apart one end distance of dividing plate 4 with roller 5, form a closed insulated cavity, filling with insulation material 3 in insulated cavity, forms heat insulation structural; In the present embodiment, heat-barrier material 3 is alumina silicate fibre.
Roll shaft 1 and roller 5 junction, be provided with heat insulating coat 2 between roll shaft 1 outer wall and roller 5 endoporus.
