Abstract

The utility model discloses a wear-resisting bush of a roller, which comprises a roller body, wherein the outside surface of the roller body is distributed with concave pits, hard materials with the hardness (HRA) being greater than 70 are inlaid in the concave pits, and the outer end face of the hard materials is flush with or protrudes out of the outside surface of the roller body. Compared with the prior art, the utility model is convenient to replace, saves cost, and has the characteristics of high reliability and long service life.

Description

The roller anti-wearing liner

Technical field

The utility model relates to the part of engineering goods, is used for the roller anti-wearing liner of impact wear protection in especially a kind of engineering goods.

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 change and frequently directly to cause productive costs to increase, 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 in the outsourcing of metal roller covers the anti-wearing liner that one deck is made 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.

Summary of the invention

Technical problem to be solved in the utility model provides the roller anti-wearing liner of a kind of abrasive resistance height, long service life, dependable performance.

The technical scheme that the utility model adopted is as follows: it includes body, the outside face of described body is distributed with pit, in these pits, be inlaid with hardness HRA〉70 hard material, the outer face of this hard material is concordant or protrude in the outside face of described body.

In the such scheme, described pit generally is circular blind hole or the through 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 ~ 20 millimeters of described outer surface of tube body, 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, abrasive resistance height, long service life and replacing are convenient: compare with the anti-wearing liner of making as glue, can prolong service life of the present utility model more than 5 times, long service life, abrasive resistance is higher; If just lining is frayed, can change a new lining, very convenient.

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, roller anti-wearing liner shown in Figure 2, it it include body 1, the diameter that is intensively distributed with honeycomb arrangement at the outside face of body 1 is the blind cylindrical hole of 12.2mm, in these blind holes, be inlaid with hardness HRA and be 72 make 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 body 1, 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.

During use, the utility model directly is enclosed within on the metal roller, the at both ends firm welding gets final product again.
