Abstract

The utility model discloses a carrier roller of a belt conveyor and relates to the technical field of parts of the belt conveyor. The carrier roller mainly comprises a roller, a roller shaft, a bearing, a tile box and an oil seal, and is characterized in that the outer side of the tile box is inwards extended to form a flange, the outer side is obliquely connected to the flange, the flange of the tile box is arranged in a seam allowance on an inner surface of the roller, an outward angle is formed between the flange of the tile box and the end part of the roller, an arc-shaped edge is welded on the outward angle to form smooth transition, so that a sharp angle formed by welding of the common tile box is avoided, thus a belt is protected. The carrier roller has the advantages of simple structure, reasonable design and convenience for use, the tile box is provided with the flange which is parallel to the inner surface of the roller, the outer side is obliquely connected to the flange, the flange is arranged in the seam allowance on the inner surface of the roller, and the arc-shaped transition is formed by welding on the outward angle between the flange and the edge of the roller, the tile box and the roller are accurately located, the outer side of the tile box cannot protrude outside the roller to influence the overall aesthetic sense, and the roller is effectively prevented from rubbing the belt, and the service life of the belt is prolonged.

Description

The belt conveyer carrying roller

Technical field

The utility model relates to belt conveyer accessory technical field, is specifically related to a kind of belt conveyer carrying roller.

Background technology

Carrying roller is the main parts size of belt conveyer, as shown in Figure 1, existing belt conveyer carrying roller is mainly by roller 1,

roll shaft

2,3 watts of boxes 4 of bearing and oil sealing 7 are formed, the outside of watt box 4 links to each other with the inner surface edge of roller 1 is vertical, in forming one between the outside of watt box 4 and roller 1 inside face to the angle 5, by interior to the angle 5 places weld, thereby roller 1 and watt box 4 are connected to each other, but the carrying roller of this connection structure, because the roller end is more straight, in use, the frequent friction belt of the edge of roller 1 meeting, cause belt impaired, shortened the service life of belt.

The utility model content

The purpose of this utility model provides a kind of belt conveyer carrying roller, to solve the roller edge abrasion belt that prior art exists, shortens the belt problem in service life.

The utility model mainly is made up of roller, roll shaft, bearing, watt box and oil sealing; the outside that solves technical scheme that its technical matters adopts and the be watt box flange that extends internally out; the outside is connected with flange is oblique; the flange of watt box is placed in the rim of the mouth of roller inside face; form an exocentric angle between the flange of watt box and the roller end, welding forms curved edge, transition slyness at the exocentric angle place; avoided the wedge angle of common watt of box welding, to realize the effect of protection belt.

The utility model is simple in structure, reasonable in design, easy to use, watt box setting flange parallel with the inside face of roller, the outside is connected with flange is oblique, a 75 type flange watt box end face is flat, we are oblique, and with the outermost end that guarantees jump ring and carrying roller in one plane, flange is placed in the rim of the mouth of roller, and the welding of the exocentric angle place between flange and roller edge forms arc-shaped transition, not only accurate positioning between watt box and the roller can also avoid a watt box outside to protrude from outside the roller, influences overall aesthetics, and can prevent roller friction belt, the service life of having improved belt effectively.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structural representation of existing belt conveyer carrying roller;

Fig. 2 is the enlarged diagram of a-quadrant among Fig. 1;

Fig. 3 is structural representation of the present utility model;

Fig. 4 is the enlarged diagram in B zone among Fig. 3.

In 1 roller among the figure, 2 roll shafts, 3 bearings, the 4 watts of boxes, 5 to the angle, 6 exocentric angle, 7 oil sealings, 11 rims of the mouth, 41 outsides, 42 flange.

The specific embodiment

As shown in Figure 2: a kind of belt conveyer carrying roller; mainly formed by roller 1, roll shaft 2, bearing 3, watt box 4 and oil sealing 7; the outside 41 of watt box 4 flange 42 that extends internally out; outside 41 and 42 oblique connections of flange; the flange 42 of watt box 4 is placed in the rim of the mouth 11 of roller 1 inside face; form an exocentric angle 7 between the flange 42 of watt box 4 and roller 1 end; welding forms curved edge at exocentric angle 7 places; the transition slyness; avoided the wedge angle of common watt of box welding, to realize the effect of protection belt.

Claims

1. belt conveyer carrying roller, mainly formed by roller, roll shaft, bearing, watt box and oil sealing, the outside that the it is characterized in that watt box flange that extends internally out, the outside is connected with flange is oblique, the flange of watt box is placed in the rim of the mouth of roller inside face, form an exocentric angle between the flange of watt box and the roller end, welding forms curved edge, transition slyness at the exocentric angle place.
