Abstract

The utility model discloses a UHMW-PE plastic carrier roller of a belt conveyor. A transmission shaft (7) is arranged in a roller (1); the inside of the both sides of the transmission shaft (7) are respectively provided with a slide bearing (4), (6); one end of the transmission shaft (7) is provided with a thrust boss and a thrust baffle plate (5) is installed on the thrust boss. The inner and the outer sides of a baffle plate (10) and a spring snap ring (8) are provided with double layers of sealing rings (3), (9) whose end heads are provided with sealing plugs (2) to increase the sealing property of shaft ends. The utility model has the advantages of good impact resistance property, abrasion resistance property, corrosion resistance property, self-lubricating property, etc. The utility model can be used for materials conveying, storage, transportation and processing in metallurgy industres, mine industries, harbor industries, chemical industries, foodstuff industries, etc.

Description

Belt conveyer UHMW-PE plastic conveyer roller

The utility model belongs to the conveying machinery part, particularly a kind of belt conveyer UHMW-PE plastic conveyer roller that is used for.

At present, belt conveyer is widely used in industries such as factory, mine, chemical industry, grain storage and transportation as the means of delivery of bulk material or member article.Its matching component carrying roller overwhelming majority is that the metal construction carrying roller of antifriction-bearing box is installed, and its shortcoming is heavy, corrosion resistant not, is easily sneaked into by foreign matter or because of acid and alkali corrosion, " axis " phenomenon often appears in carrying roller.Do not change as continuous several carrying rollers " axis " on same conveyer, then become cliding friction between belt and the carrying roller, the belt-driving resistance is gathered increase, quicken friction.According to using field statistics, metal construction carrying roller general 3-4 in service life month, not only waste energy, and the long-term frictional heating of belt, burning, have an accident.

The purpose of this utility model is to overcome above technical deficiency, and the belt conveyer UHMW-PE plastic conveyer roller that a kind of economical with materials, withstanding corrosion, intensity are good, the life-span is long is provided.

Task of the present utility model is belt conveyer UHMW-PE plastic conveyer roller, the belt conveyer UHMW-PE plastic conveyer roller of forming by the bearing of installing on the roller intermediate solid drive shaft, seal ring, inboard, transmission shaft two ends in roller is installed plain bearing respectively, be provided with on the thrust boss at transmission shaft one end thrust baffle is installed, in the interior outside of baffle plate, retainer ring the double-layer seal circle is installed, the termination is equipped with sealing and is blocked up, and the double-layer seal circle is rubber seal and labyrinth seal circle, increases shaft end seal.

On the lengthening carrying roller, adopt roller intermediate solid drive shaft middle part mounting support plain bearing, increase the rigidity of carrying roller, prevent carrying roller flexural deformation.

Belt conveyer UHMW-PE plastic conveyer roller, one are installed plain bearing and are replaced antifriction-bearing box in roller, solved the problem of metal carrying roller " axis "; It two is provided with on the thrust boss at transmission shaft one end thrust baffle is installed, and prevents end float misalignment; Its three axle head adopts two seal structures, avoids foreign matter to invade, guarantee the friction pair cleaning; Its four carrying roller adopts UHMW-PE plastics extrusion moulding, has intensity height, long, resistant to corrosion characteristics of life-span.

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 shows belt conveyer UHMW-PE plastic conveyer roller structure.

Fig. 2 shows belt conveyer UHMW-PE lengthening plastic conveyer roller structure.

1-roller among the figure; The 2-sealing is stifled; The 3-rubber seal; The 4-plain bearing; The 5-thrust baffle; The 6-plain bearing; The 7-transmission shaft; The 8-retainer ring; 9-labyrinth seal circle; The 10-baffle plate; Plain bearing in the middle of the 11-

Among Fig. 1, belt conveyer UHMW-PE plastic conveyer roller, go up the bearing of installing (4) by roller (1) intermediate solid drive shaft (7), (6), seal ring (3), (9) form, transmission shaft (7) inboard, two ends in roller (1) is installed plain bearing (4) respectively, (6), be provided with at transmission shaft (7) one ends thrust baffle (5) is installed on the thrust boss, prevent roller (1) longitudinal travel, in baffle plate (10), double-layer seal circle (3) is installed in the interior outside of retainer ring (8), (9), sealing stifled (2) is equipped with in the termination, and double-layer seal circle (3) is that rubber seal and (9) are the labyrinth seal circle.Roller (1) and plain bearing (4), (6) are the UHMW-PE plastic shaping.

Fig. 2 increases the rigidity of carrying roller for the embodiment of belt conveyer UHMW-PE lengthening plastic conveyer roller, transmission shaft (7) the middle part mounting support plain bearing (11) in roller (1) is the UHMW-PE plastic shaping, prevents distortion.

Belt conveyer UHMW-PE plastic conveyer roller technical performance:

1. strength under shock 〉=800CJ-cm/cm ²

2. disruption characteristic 2900N/cm ²

3. breaking elongation 300%;

4. density 0.935-0.94g/cm ²

5. friction coefficient 0.07-0.11;

6. operating temperature is below 90 ℃, and low temperature still has certain intensity under-269 ℃.

Belt conveyer UHMW-PE plastic conveyer roller, extrusion moulding, roller keeps the mol wt 250-300 ten thousand of raw material, deadweight is 1/3 of metal construction, life-saving 3-4 times, superior performance is the outstanding person of engineering plastics, have good Dent resistance, abrasion test, corrosion stability, self lubricity etc., be widely used in mass transport, accumulating, the processing of industries such as metallurgy that belt conveyer uses, mine, harbour, chemical industry, grain.
