Abstract

The utility model belongs to the technical field of carrier rollers and discloses a high-strength carrier roller. The high-strength carrier roller is mainly technically characterized by comprising a carrier roller body, a revolving shaft and a bearing, wherein the carrier roller body is composed of plugging surfaces on both ends and a roller body side surface, the roller body side surface is a curved surface formed by rotating curves which are axially symmetric around the revolving shaft for a circle around a straight line in which the revolving shaft is positioned, so the cross section of a conveyor belt can be ensured to be low in the middle and high in both sides, materials can be prevented from falling, and further the diameters of the revolving shaft and the bearing can be increased, thus the whole strength of the carrier roller can be improved, the service life can be prolonged, the computation of the materials can be increased, and the working efficiency can be improved.

Description

The high strength carrying roller
Technical field
The utility model belongs to the Idler Technology field, relates to the high strength carrying roller concretely.
Background technology
In the mine, occasions such as harbour, factory, the carrying roller that is used for mass transport is used more and more wider, in order to improve transport efficiency, the requirement of strength of carrying roller is also strengthened gradually; Carrying roller mainly contains two kinds at present: one of which, and the serial type carrying roller, this carrying roller is by the drag hook serial connection of three cylindrical carrying rollers through the rotating shaft two ends; Bearing is little, and tube wall is thin, in material conveying process; The force direction that receives of rotating shaft and bearing is a direction of tilt, causes rotating shaft and bearing failure, reduces service life; Its two, groove profile carrier roller is provided with support at the two ends of by-level carrying roller, though make flat idler rotating shaft and bearing receive force direction vertical with rotating shaft, the force direction that receives of two tilt carrying rollers still tilts, and has increased cost.
The utility model content
The technical matters that the utility model solves just provides a kind of simple structure, and intensity is high, the high strength carrying roller of long service life.
For solving the problems of the technologies described above; The technical scheme that the utility model proposes is: comprise carrying roller body, rotating shaft and bearing; Said carrying roller body comprises that the shutoff face that is positioned at two ends and roll body side form, described roll body side for about the curve of the axial symmetry of said rotating shaft around said rotating shaft place the straight line gained curved surface that rotates a circle.
Its additional technical feature is:
Described curve is a hyperbola;
Described curve is a parabola;
On described roll body side, be arranged at intervals with dashpot along rotor shaft direction.
The high strength carrying roller that the utility model provides, comparing with prior art has the following advantages: one of which, owing to comprise carrying roller body, rotating shaft and bearing; Said carrying roller body comprises that the shutoff face that is positioned at two ends and roll body side form, described roll body side for about the curve of the axial symmetry of said rotating shaft around said rotating shaft place the straight line gained curved surface that rotates a circle, like this; Both guaranteed that the load-transfer device cross section presents middle low both sides height, prevented that material from coming off, and can also improve the diameter of rotating shaft and bearing; Thereby improve the bulk strength of carrying roller; Prolong service life, increased the operand of material, improved work efficiency; Its two because described curve is hyperbola or parabola, not only be convenient to processing, and each point is stressed evenly, has further prolonged its service life; Its three owing on described roll body side, be arranged at intervals with dashpot, when material drops on the load-transfer device, play buffer action along rotor shaft direction.
Description of drawings
Fig. 1 is the structural representation of the utility model high strength carrying roller;
Fig. 2 is the structural representation that has the carrying roller of dashpot.
The specific embodiment
Further specify below in conjunction with the structure of accompanying drawing the high strength carrying roller that the utility model proposed.
As shown in Figure 1, be the structural representation of high strength carrying roller.Its structure comprises carrying roller body 3, rotating shaft 2 and bearing 1, and carrying roller body 3 can adopt metallic material, nylon material etc. to process, and carrying roller body 3 comprises the shutoff face 31 and roll body side 32 compositions that is positioned at two ends; Roll body side 32 is for about the curve of the axial symmetry of the rotating shaft 22 place straight lines gained curved surface that rotates a circle around the shaft, like this, both guaranteed the load-transfer device cross section appear in the middle of low both sides high; Prevent that material from coming off; And can also improve the diameter of rotating shaft 2 and bearing 1, thus improve the bulk strength of carrying roller, prolonged service life; Increase the operand of material, improved work efficiency.
Curve can be hyperbola as shown in Figure 1, also can be parabola, like this, not only is convenient to processing, and each point is stressed evenly, has further prolonged its service life.
As shown in Figure 2, on roll body side 32, be arranged at intervals with dashpot 4 along rotor shaft direction, when material drops on the load-transfer device, play buffer action.
The protection domain of the utility model not only is confined to the foregoing description, as long as structure is identical with the utility model high strength idler structure, just drops on the scope of the utility model protection.

Claims (4)
