Abstract

The utility model discloses a roller body of an external teeth type roller, which comprises a roller body of the roller, and is characterized in that the outer surface of the roller body of the roller is not smooth and provided with a protrusion teeth structure in a regular tip surface shape or an irregular bump shape. Compared with a traditional roller body of the roller, the outer surface of the novel roller body of the roller is changed into a structure with protrusion teeth, rigidity of the whole roller body is reinforced under the premise that raw materials are used as few as possible, and equivalently effective thickness of the roller body is increased, thickness of a wear-resistant layer on the surface is increased, abrasion is reduced and service life of the roller is prolonged.

Description

External tooth type carrying roller roll body

Technical field

The utility model relates to a kind of external tooth type carrying roller roll body, belongs to belt conveyor tool accessory.

Background technology

Carrying roller is main transmission, the load-carrying parts on the belt transporting facility, loads and belt conveyor are pressed on the carrying roller, meeting severe wear carrying roller roll body, and because it is the hollow roll body structure, roll body very easily produces vibration in the transmission course, more bending can take place for a long time, cause carrying roller to damage, maintenance rate is very high.

Summary of the invention

The purpose of this utility model is to improve the weak point of prior art, and the external tooth type carrying roller that a kind of rigidity is big, resistance to abrasion is good roll body is provided.

The technical solution of the utility model is: a kind of external tooth type carrying roller roll body, include the carrying roller roll body, and characteristics are, the outside face of carrying roller roll body is not the light face, but being provided with the double wedge structure, this double wedge structure can be the tip surface shape structure of rule, also can be fitfull convex dot shape structure.

Traditional idler roll surface all is smooth, and is not wear-resisting, and the poor rigidity of whole roll body, and easily because of bending takes place the long-time vibration of roll body, abrasion factor is very high during use.The utility model changes over the structure with double wedge with the external surface shape of roll body, under few raw-material prerequisite is tried one's best in use, increased the rigidity of whole roll body, and be equivalent to make the roll body effective thickness to increase, the wearing layer thickening on surface, reduce wearing and tearing, prolonged the service life of carrying roller.

Below in conjunction with drawings and Examples the utility model is done and to be described in detail.

Description of drawings

The structural representation of Fig. 1-existing carrying roller roll body;

Fig. 2-a kind of structural representation of the present utility model;

Fig. 3-another kind of structural representation of the present utility model.

The explanation of accompanying drawing drawing:

1 carrying roller roll body, 2 roller carrier shafts, 3 tip surfaces, 4 salient points.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, the utility model is that the carrying roller roll body 1 that will have carrying roller improves, the outside face of existing carrying roller roll body 1 all is smooth, and the outside face of present technique carrying roller roll body 1 is not smooth, it has bulge-structure, bulge-structure can be tip surface 3 shapes of rule, also can be fitfull salient point 4 shapes.

In fact the tip surface structure or the bump structure of idler roll surface have played the effect of reinforced rib, can strengthen the rigidity of roll body greatly.In addition, in use, material disintegrating slag on the belt conveyor (as coal dust, dust, various material particles etc.) can fill up the space between tip surface or the salient point very soon, form new roller wall, not only equaled to increase the wall thickness of carrying roller roll body, and the wearing layer that forms is solid more wear-resisting with respect to former roll body, and dregs such as coal dust also have certain lubricating effect, have reduced the wearing and tearing between carrying roller and the belt conveyor.

Claims
