Abstract
The utility model discloses a wear-resistant roller. The outer surface of a cylinder body made of metal matrix is distributed with concave pits which are internally embedded with a hard material with the hardness HRA of more than 70. The outer end surface of the hard material is parallel and level or protrudes out of the outer surface of the cylinder body. Compared with the existing wear-resistant roller, the wear-resistant roller is characterized by high reliability and long service life.
Description
Technical field
The utility model relates to transmitting uses the roller technical field, and particularly a kind of being used under the belt conveyor is used to carry or provide the roller of transmitting power.
Background technology
At present, in all conglomeraties such as electric power, metallurgy, cement, mine, the carrier that the metal roller that people adopt steel to be processed into is mostly carried as belt.Because the friction force of steel is little, belt skids easily, and resistance to abrasion is limited, and roller is worn easily, the life-span short, thereby changes and frequently directly cause productive costs to increase, and has also increased the weight of working strength of workers simultaneously.In order to reduce the loss that the belt roller causes because of wearing and tearing, people generally adopt to be covered one deck in the outsourcing of metal roller and makes wear-resisting roller as glue, increase friction force and wear resisting property with this, the encapsulate face adopts rubber as the power transmission medium, the plane is generally arranged, chevron pointing, glue faces such as rhombus, also obtained good effect under certain condition, but deficiency is arranged simultaneously again, it is normal because the glue surface hardness is low, when hard ware material sandwiches belt and roller, very easily be scratched, thereby use to such an extent that the roller surface glue-line comes off or weares and teares, former thereby inefficacy such as scuffing, its wear resisting property is limited, and the life-span is short.
The utility model content
Technical problem to be solved in the utility model provides a kind of abrasive resistance height, long service life, the wear-resisting roller of dependable performance.
The technical scheme that the utility model adopted is as follows: this wear-resisting roller includes the cylindrical shell of metal matrix in the prior art, outside face at this cylindrical shell, be distributed with pit, be inlaid with the hard material of hardness HRA＞70 in these pits, the outer face of this hard material is concordant or protrude in the outside face of described cylindrical shell.
In the such scheme, described pit generally is the circular blind hole that the method for employing boring is processed into, and described hard material the most frequently used be the cylindrical ceramic material, the general cylindrical abrasion resistant alloy pottery of being made by the high alumina corundum material that adopts just can obtain good wear-resisting effect; Between described hard material and described pit, preferably be filled with adhesives, as the adhesives of epoxy matrix material with certain buffer action.According to the applying working condition difference, the outer face of above-mentioned hard material generally can protrude in 3～10 millimeters of described metal cylinder outside faces, is filled with antifriction rubber between the raised face of the outer end of hard material.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, long service life.Cover one deck with the outsourcing of metal roller and make wear-resisting roller as glue and compare, can prolong more than 5 times service life of the present utility model.
2, reliability of service height.Be not easy to cause inefficacy because there is hard ware material to sandwich between belt and the roller.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:
Fig. 1, wear resistant roll shown in Figure 2, the cylindrical shell 1 of the metal matrix that its tool is same as the prior art, the diameter that is intensively distributed with honeycomb arrangement at the outside face of cylindrical shell 1 is the blind cylindrical hole of 12.2mm, be inlaid with in these blind holes that hardness HV=HRA＞70 are made by the high alumina corundum material, diameter is the cylindrical abrasion resistant alloy pottery 2 of 12mm, the outer face of abrasion resistant alloy pottery protrudes in 5 millimeters of the outside faces of cylindrical shell, between the hole wall of abrasion resistant alloy pottery and blind hole, be filled with the adhesives 4 of epoxy matrix material, the antifriction rubber 3 of between the raised face of the outer end of abrasion resistant alloy pottery, filling.
