There are 3 main types of bearing seal structure

Bearing seal structure and lubrication is also an important factor affecting the service life and running resistance of roller. There are 3 main types of bearing seal structure:
1) the labyrinth seal sealing operation of small resistance, good dustproof performance, but poor water resistance, poor sealing effect, the roller working at low temperature, the rotating resistance is under normal temperature increased exponentially, should pay attention to when using low temperature area;
2) contact seal, sealing effect is better than non - contact, but the resistance is too large;
3) group mediated seal is a kind of mixed media sealing method of the first two advantages.
Coal dust sealing performance, the roller to 1450r eight Nin speed of operation after 200 hours, the coal dust into the bearing grease content of more than 0.8%, the roller is still running normally.
Sealing performance of the water, the roller in the 1450r/min speed of 24 hours after the operation, the amount of water less than 150g.
Water sealing performance, the roller in the 1450r eight Nin speed of operation after 120 hours, the water intake is less than 250g.
The selection of the roller bearing and its lubrication bearing is an important part of the roller, and its selection is appropriate, the quality is good or bad, which is related to the service life of the roller. Bearings should be preferred KA series roller bearings, and the relevant provisions of the relevant provisions. In the operation of L, the speed of the roller is higher, which mainly bear radial force, but at the same time bear the axial force. Early usually uses 204205 series rolling bearings, special bearings with small fault appears, now tend to use special shaft conveyor and material movement on the dynamic load impact roller, which can greatly improve the overall quality of bearing. According to the above characteristics and the cost of roller, the actual production of the general use of large deep groove bearing. Its performance shall be in accordance with the relevant national standards.
Excessive wear is the main failure form of the rolling bearing, and the lubrication is small, the lubricant variety or component is the key factor of excessive wear. Therefore, in the selection of rolling bearing lubrication method lubricant varieties must be highly valued. From the way of lubrication in two ways: the first roller disposable lubrication little long term operation of the medium, when the roller in the later stage of wear, the running resistance increases with}h}, while the bearing life is short; second kinds of lubrication oil filling can keep good lubrication bearing Yu Liang, will bearing raceway in the dirt out, improve the service life of the bearings, roller running resistance remained constant.
As an important part of the conveyor, the design performance of the roller has a good effect on the overall performance of the conveyor. In the design of roller on the main use of qualitative analysis and quantitative calculation of combined dielectric method, calculation of the static characteristics of the roller have been mature, to calculate the dynamic characteristics have to be further improved; the dynamic design method of node dielectric conveyor, comprehensive consideration of dielectric processing, installation, disassembly and interchangeability. However, empirical data on the design manual and reference data are given, according to the actual operation simulation of belt conveyor, determine the referral carrying idler spacing.
