Vertical 76mm Dia Belt Conveyor Rollers 3.0mm Thick For Heavy Duty
Heavy-Duty Belt Conveyor Vertical Roller Aligning Roller Group
The vertical roller is mainly connected with the self-aligning bracket. It is a product used in the self-aligning roller. The vertical roller is installed on both sides of the conveyor belt to prevent the conveyor belt from deviating. That is to say, when the tape deviates, one of the wing rollers is squeezed, the vertical roller rotates around the shaft on the rotating mechanism through the moving rod, the shaft drives the pull rod to rotate, and the final pull rod pushes the entire roller set to rotate by an angle, so that the tape runs smoothly , Adjusting the center, and simple structure, can meet the needs of modern operation development.
The influence of the flexibility of the roller on the belt conveyor:
During the operation of the belt conveyor, the flexibility of the
roller is very important. If the roller is not flexible and the
coefficient of rotation resistance is high, the entire belt
conveyor system will have to pay a lot of power and consume a lot
of electricity. Sometimes it will cause the tape to tear and the
motor to burn out. In severe cases, it can cause a fire. Therefore,
the selection of idlers with low rotation resistance coefficient
(well less than 0.020) is an important part of the design and
selection of belt conveyors.
How to maintain the sealing performance of the Impact roller?
(1) The labyrinth seals should be made of original parts, and should be put into the rollers during assembly, and should not be assembled together.
(2) For the sealing performance and use performance of the roller, it is forbidden to disassemble the roller at will.
(3) The normal service life of the roller is more than 20000h, and generally does not need to be repaired. However, according to the place of use and the size of the load, the corresponding maintenance date should be established, and the oil injection maintenance should be cleaned in time, and the floating coal should be cleaned in time. The rollers with abnormal noise and non-rotating should be replaced in time.
(4) When replacing the bearing, the opening of the bearing cage needs to be opened outwards. After the bearing is installed into the idler, the proper clearance should be maintained and it should not be crushed.
(5) During the use of the idler, prevent heavy objects from hitting the idler tube.

Reasons for the damage of the Impact roller:
1. Due to the large amount of dust at the blanking point, the
Impact roller can easily be contaminated and cause damage to the
bearing when the sealing performance of the Impact roller is poor.
2. The cushion rubber ring is basically made of recycled rubber,
not only has poor elasticity, but also has poor wear resistance,
tear resistance, and aging resistance. The impact force is small,
and the service life is only about 1 year. When the impact force is
large , It will break and fall off within ten days, causing serious
damage to the tape. In desperate circumstances, many belt conveyors
began to choose expensive impact beds.
