Abstract
The utility model discloses a wear-proof integral carrier roller. The wear-proof integral carrier roller comprises rolling shafts and a roller, wherein the rolling shafts are arranged at the two ends of the roller; the rolling shafts and the roller are of an integral structure with an axial through hole formed in the middle; the through hole comprises a bore-hole with big ends towards the two ends; the further improvement is as follows: the rolling shafts are connected with the roller through circular beads in a transition manner, and a wear-proof alloy layer is arranged on the outer surface of the roller, 1.0-1.5 mm in thickness, and a wear-proof cemented tungsten carbide alloy layer. According to the utility model, the manufacturing procedure is few, the structural strength is high, the abrasive resistance is good, and the service life is long.
Description
Technical field
The utility model relates to equipment for Heating Processing, relates in particular to a kind of heat treatment furnace carrying roller.
Background technology
At present, heat treatment furnace is welded after mostly being more piece sleeve pipe suit with carrying roller.The carrying roller of this structure operation in the time manufacturing is more, and easy sealing-off in use, and intensity is low, and work-ing life is short.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes a kind of manufacturing process few, and structural strength is high, and wear resistance is good, the wear-resisting monoblock type carrying roller of long service life.
The utility model is achieved through the following technical solutions technical object.
Wear-resisting monoblock type carrying roller, comprises roll shaft and roller; Described roll shaft is placed in roller two ends; Its improvements are: described roll shaft, roller are provided with the one-piece construction of axially extending bore in the middle of being; Described through hole comprises the taper hole of large end towards two ends.
In said structure, between described roll shaft and roller, be connected by round-corner transition.
In said structure, the outside surface of described roller is provided with wear-resistant alloy layer.
In said structure, described wearing layer thickness is 1.0～1.5mm.
In said structure, described wear-resistant alloy layer is carburized tungsten wear-resistant alloy layer.
The utility model compared with prior art, has following positively effect:
1. carrying roller adopts one-piece construction, has simplified operation, and no-welding-seam, significantly improves structural strength, has avoided the inefficacy that causes because of sealing-off, has significantly improved work-ing life.
2. between roll shaft and roller, be connected by round-corner transition, avoided stress concentration, prevent the generation of crackle.
3. carrying roller surface increases wear-resistant alloy layer, has effectively improved surface hardness and the fatigue resistance of carrying roller, and good toughness.Wearing layer is carburized tungsten wear-resistant alloy layer, and carburized tungsten wear-resistant alloy layer is combined with body firmly, and difficult drop-off has effectively improved wear resistance.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Embodiment
