Friction Belt Conveyor Rollers

Friction Belt Conveyor Rollers

Trough Carrier Impact Rubber Belt Conveyor Idler Roller

The conveyor roller has light weight and low rotation inertia. The special polymer material for roller is light in weight, and its specific gravity is one-seventh of steel. The roller made of this material is about one-half of the weight of ordinary roller, and the rotation inertia is small. It is between the roller and the belt. The friction is small.

Main classification

1. According to the material, it is divided into rubber roller, ceramic roller, nylon roller and insulating roller.
2. There are mainly trough roller groups, various parallel roller groups, various self-aligning roller groups, and various buffer roller groups.
(1) Groove idlers include ordinary idlers, forward inclined idlers, quick-change bearing idlers, hanging idlers, triple chain idlers, reversible idlers, variable groove angle idlers, and transitional idlers. Roller, V-shaped roller, etc.;
(2) Parallel idlers include ordinary idlers, comb idlers, forward inclined idlers, steel rubber idlers, spiral idlers, etc.;
(3) Self-aligning rollers include universal rollers, friction reversible rollers, powerful rollers, cone rollers, spiral rollers, combined rollers, etc.;
(4) Cushioning rollers include spring plate type rollers, buffer ring type rollers, powerful buffer type rollers, adjustable elastic type rollers, hanging type rollers, etc.

The high-quality roller support device is not only easy to replace the roller support device of the roller, it is composed of a deflectable roller support, a support, a pin shaft, a body, a roller, a limit block and a fastener. The lower end of the support and the upper end of the machine body are connected together with fasteners, and the support is connected with the deflectable roller support by a pin, and the support roller is arranged on the deflectable roller support. The deflectable roller bracket is provided with a slot for rotating around the pin axis, and the roller is installed in the slot of the deflectable roller bracket, and a limit block for controlling the deflection angle is arranged on the deflectable roller bracket .

Main advantages of belt conveyor rollers: long life and high energy saving

1. High wear resistance: Use Q235 type precision roller special steel pipe with strong wear resistance, which is 3~5 times that of traditional steel roller;
2. Customized Luoyang or human-based professional support shaft bearings, with significantly longer service life, light weight and convenient operation;
3. The company's practical patented seal: no leakage of lubricating grease, which can effectively waterproof and dustproof;
4. High and low temperature resistance: It can work in the temperature range of minus 40°C to 120°C;
5. Corrosion resistance: resistant to salt, alkali and acid, adapt to harsh working environment;
6. Excellent mechanical properties: high strength, good toughness, and strong drop resistance;
7. Non-sticking: The surface is smooth and non-sticky materials, and the hollow device can make the stained objects fall off by themselves;
8. Antistatic and flame retardant: have good antistatic and flame retardant safety performance;
9. High economic efficiency, can reduce operating costs such as maintenance man-hours, and improve economic efficiency.

Belt Conveyor Idler Roller​ Specification

Interaction between roller and conveyor belt

1. The influence of the radial runout of the roller on the belt conveyor
The national standard for the radial runout of the idler rollers in my country is 0.7 mm. Within the range of the amount of runout specified by the country, the belt conveyor can be kept running smoothly, otherwise it will cause the belt conveyor belt to resonate and jump, resulting in material throwing, polluting the environment, and the advantage of small radial runout will be under the condition of high belt speed. Obviously flashed.
2. The influence of roller sensitivity on belt conveyor belt
If the roller sensitivity is not good and the rotation resistance coefficient is high, the entire belt conveyor system will have to pay more power and consume more electricity. Sometimes the belt will tear and the motor will be burned. When it is more severe Can cause a fire. Therefore, during the operation of the belt conveyor, the sensitivity of the roller is very important. The selection of rollers with a low coefficient of rotation resistance is an important part of the design and selection of the belt conveyor.
3. The influence of axial movement on the belt conveyor
Although my country’s conveyor manufacturing skills are becoming more and more advanced, axis movement is still a subject of research. Due to my country’s current belt manufacturing skills, belt conveyor installation skills are still far away from advanced countries in the world. There will be a situation where the tape is deviated. If the amount of axial movement of the idler is large, it will cause early damage to the idler. Generally, we control the amount of axial movement within 0.5-0.7 mm.
