Analysis of the Causes of Runout in Rubber Roller Operation

After one year of use, the glazing machine was equipped with a new glazing roller and put it into trial operation. As a result, the roller leaped more severely and could not be used.

What causes the runout of the rubber roller?

Some people think that the gap between the roller neck and the bearing sleeve of the rubber roller is too large or the matching between the bearing sleeve and the adjustable track surface is poor. Some people think that the roller itself has quality defects and affects the normal operation of the rubber roller. . For this purpose, we tested and analyzed the mating surfaces and the mating dimensions of the bearing sleeve one by one, and the results were all normal. We also placed the rubber roller on the lathe to measure the circular runout of the rubber roller and the diameter of multiple parts with a dial indicator. The measurement results show that the round runout and diameter tolerance of the rubber roller are within the range of first-class products. From this point of view, it seems that there are no problems with the size and assembly size of the coating machine and the roller.

What is the reason for the runout of the rubber roller? We put an old rubber roller that has been worn out and scrapped on the glazing machine to run. As a result, the old rubber roller runs smoothly and does not produce large jumps. This shows that the main reason for the large jump in the operation of the new rubber roller is that The roller itself has a quality defect. On this basis, we conducted in-depth understanding and analysis, and finally determined that the main cause of the beating of the new rubber roller during operation was the existence of mass eccentricity of the rubber roller. If the eccentricity of the rubber roller is not eliminated in the roller, the unbalanced force generated during operation will inevitably stir the roller. To take regular production process and quality control, during the process of making the rubber roller, it is necessary to ensure that the roller does not have mass eccentricity defects through static balance or balancing and other measures so that it will not be generated due to unbalance during use. beat.
