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.
