The role of the Bearing in rubber belt conveyor system

The role of the bearing in conveyor component, bearing have many types, such as ball bearing, needle bearing and so on. Actually, when using a belt conveyor, it is not only necessary to check the operation of the idler frequently, but also the operation of the idler bearing. In the Belt conveyor system, the rollers are play the important role, but the bearing will influence the operation of rollers directly. So bearings are also the important component, but how to determine the quality of the bearing, that's the point, let's we talk the details:

To determine whether the roller bearing can be reused, we must first use the disassembly tool correctly to avoid damage to the roller bearing. After disassembly, we need to see whether the bearing components are broken or the balls are damaged. We must check the dimensional accuracy and whether the rotation is correct. Smooth, if there is abnormal noise, if you find the bearing has been damaged, please replace it. We must regularly check the operation of the idler and regularly maintain it. If the idler does not rotate, it will seriously wear the belt and the loss will be great. The quality of the roller bearing seat also directly affects the mounting accuracy of the roller bearing. The precision of the bearing seat affects the axial positioning density of the bearing, and also affects the fitting accuracy of the roller bearing and the bearing seat. Therefore, the quality of the roller accessories is very important, it directly affects the quality and life of the roller.

Roller bearing clearance selection, that is, when the idler bearing is not installed on the shaft or the bearing housing,one of its inner ring or outer ring is fixed,then the amount of movement when the unfixed one is moved radially or axially According to moving direction,can be divided into radial clearance and axial clearance.The amount of play during operation (called work clearance) affects the rollover fatigue life, temperature rise, noise, and oscillation of the bearing. When measuring the clearance of the bearing, in order to obtain a stable measurement value, a regular measurement load is usually imposed on the bearing. Therefore, the measured value obtained is larger than the true clearance (called the theoretical clearance), thus the amount of elastic deformation of the measured load increases. However, with respect to roller bearings, the internal clearance of the front idler bearing is usually indicated by the theoretical clearance. The bulging or shortened play of the ferrule that occurs due to interference when the bearing device is on the shaft or in the housing is subtracted from the theoretical clearance and is referred to as "device play." The clearance after adding or subtracting the dimensional variation due to the internal temperature difference of the bearing is referred to as "useful clearance". The bearing device is mechanically subjected to a predetermined clearance for the load to be placed, that is, the amount of elastic deformation caused by the bearing load when there is a useful clearance, so as to be called a "work clearance." When the work clearance is a slightly negative value, the idle life of the idler bearing is the longest, but as the negative clearance increases, the fatigue life also decreases significantly. Therefore, when selecting the clearance of the bearing, it is usually preferable to make the working clearance zero or slightly positive.

Although the bearing is a mechanical small part, it cannot be lacking, and it plays a significant role in the performance of the machine.Three requirements for bearing use,bearings are precision components in machinery. There must be rules in use, such as what needs to be taken into account when using the environment. This will enable the bearings to function well and play an optimal role. What are the requirements for bearing use?

First, keep the bearing and its surroundings clean, even tiny dust that is invisible to the naked eye enters the bearing, increasing wear, vibration, and noise in the bearing. Bearings and their surrounding accessories should be kept clean, especially dust and dirt, tools and working environment must also be kept clean.

Second, use carefully when installing, strong punching is not allowed, hammers are not allowed, and the bearing is struck directly. No pressure is allowed to be transmitted through the rolling elements.

Third, the use of appropriate and accurate installation tools, try to use special tools and try to avoid using cloth and staple fibers.
