Ways to Judge Whether Roller Bearing is Failure

As we all know, roller is the main spare parts of belt conveyor, while bearing is precision parts of roller. But in the process of using, bearing is very easy to be damaged. How to avoid its failure? If users can identify whether the bearing is failure or not by not removing inspection, it will improve productivity greatly.

Firstly, we can judge whether the bearing is faulty or not by sound bearing which requires the operators have a lot of experience. It must go through rigorous training to judge if the sound is produced by bearing.

Secondly, we can judge it by the temperature of working device, but this method has some limitations. We need to constantly record the temperature changes to judge whether the bearing is failure in the operating conditions.

Finally, we can judge whether the bearing is fault by dirty situation of lubricant when adding lubricant to bearing. If there are other different things mixed with lubricant, then the bearing must be damaged.

What Factors Lead to Inflexible Rotation of Conveyor Roller

In our daily use of conveyor roller, inflexible rotation phenomenon may occur during the operation, what factors lead to inflexible rotation of conveyor roller? Let’s see the following two parts:

The manufacturing quality of belt conveyor idlers

The manufacturing problems of belt conveyor mainly are bearing lacks of rigidity, difficult to ensure the roller assembly accuracy , which restricts the operation flexibility.

Sealing, lubrication and maintenance

Because of belt conveyor working environment is relatively poor, generally, operation site is full of dust, and the bearing sealing form has big influence on roller operation flexibility. If sealing poor, dirt can easily enter into the bearing inner which causes inflexible rotation; in addition, if bearing grease adopts common calcium base grease ,it is easy to change color and become dry, can't reach a very good lubrication effect.

How to solve inflexible rotation problem of conveyor roller

To ensure accuracy during conveyor roller manufacturing process

Such as the inner hole precision of punch bearing housing should reach grade 3, dimensional tolerance,coaxial degree and ovality of the pipe body two ends must conform to the national standard,can not exceed the tolerance.

Sealing and lubrication

in addition to ensure the quality of manufacture, also require better lubrication materials, such as lithium base grease which can improve the bearing lubrication performance, this is very necessary to prolong the service life of roller.

Bearing seat adopts labyrinth seal structure of centripetal ball bearing supporting and plastic sealing ring, which can guarantee reasonable bearing stress of roller during operation,but also ensure good dust prevention effect, small resistance, and convenient installation and easy maintenance, it can effectively reduce the conveyor operation cost at the same time.

How to Select Vibrating Screen Coupling

Coupling is being used to connect two shafts to make them conjoined and deliver torque. It is a universally mechanical transmission component. As the vibrating screen coupling is standard component, users can choose appropriate one during use according to national standards.

Influenced by manufacturing, installation error and temperature variation, two shafts connected by coupling cannot be centring. In this case, it’s better to select cross coupling between reducer and clutch. This kind of coupling consists of one half coupling with a rut and one telophragma with protruding teeth both sides. Because the protruding teeth can move freely in the rut, it can compensate for the relative displacement between the two shafts. This kind of coupling can be made of 45# steel. And it’s better to make heat treatment in the working surface so that it can improve its hardness.

When it is put into use while two shafts has relative displacement, telophragma will generate large centrifugal force and then it will enlarge dynamic load and wear. Thus, users have better notice that working speed of this machine shall not be more than rated value.

The Role of Conveyor Belt Cleaning Device

What the cleaning device plays role in belt conveyor is that to help sweep the sticky materials.If not remove those sticky materials, they will affect the efficiency of belt conveyor and damage the return rollers.

The belt conveyor is often used to transport viscous materials, such as coal dust, mud, powder materials and etc.. Some of them will stick on the working surface of belt conveyor, which cannot be removed when discharged the materials. At this time, the adhesive material will then enter the return idler, the roller become dirty as attachment stick on it. Materials enter the roller casing, thereby increasing the radial and thrust load of bearing block, causing rapid wear of bearing. The materials deposit on the roller casing will tear the rubber surface of the belt conveyor, accelerate the wear out failure of belt conveyor. If sticky materials enter the tail bend pulley, it will stick on the surface of roller. The more the viscous materials stick on it, the greater the force of the sticky materials, which will result belt deviation and increase belt wear, leading to serious consequences.

The remaining material on the belt conveyor will increase the friction force on roller, sometimes it may cause the tear on the rubber surface of belt conveyor and also the layer of roller encapsulate. If the cleaning device can function well, it can prolong the service life of the roller, belt conveyor and etc.. This shows that the cleaning device has a significant effect on belt conveyor. In the process of operation, if you want to clean the sticky material on the tail bend pulley through anthropogenic removal, it often prone to serious bodily injury or death. Hence, in order to ensure the normal operation of the belt conveyor, the sticky material must be cleaned up by cleaning device before materials enter into the snub pulley.
