How to deal with the problem of circular vibrating screen bearing damage?
In the actual production process, the wearing part of the circular vibrating screen that is more prone to damage is the bearing, and when it has a problem, it will emit a large noise, which is easy to identify by sound. So do you know what are the specific reasons for the damage to the circular vibrating screen bearing? What do you need to do about it? Today, the technical experts of Shandong Sanxiang Heavy Industry machinery will bring you a detailed interpretation, hoping to help you:
First of all: the matching problem of circular vibrating screen bearing and bearing seat. Our company's bearings are purchased, but the bearing seat is processed and produced by the factory's stone crusher casting workshop, and then the crusher machining vehicle group for later grinding and other work. Under normal circumstances, there are few reasons for machine pumping damage due to unqualified connection between bearing and bearing seat. The reason for this situation is generally that customers purchase other products privately after the bearing seat is damaged, because the bearing and the bearing seat have a certain limit, if there is a large interference fit between them, it will cause the bearing raceway particles to geometrically bend, and the running room will appear abnormal vibration. If there is too much mating space, it will cause the bearing outer ring to do relative sliding movement in the bearing hole, resulting in the bearing being damaged due to the abnormal friction rising sharply.
Treatment: Shandong Sanxiang Heavy machinery crusher customers if you buy our factory's round vibrating screen bearing seat damage, please be sure to call our factory's crusher parts sales phone to order. The bearing housing produced by our factory has proper matching tolerances, the inner ring of the bearing and the shaft are fitted with loose transition or space fitting tolerances, and the outer ring and the bearing seat hole are fitted with tight transition or slightly smaller interference fitting tolerances, which solves the matching problem of the bearing and the bearing seat well.
Second: the bearing oil seal should not be sealed properly. The circular vibrating screen produced by Shandong Sanxiang Heavy Industry Co., Ltd. is equipped with a special oil seal system, excellent quality, and the general delivery is equipped with spare oil seal for crusher customers. Very few reasons cause the oil seal system of the machine to be poorly sealed during production, which will lead to too fast butter loss, so that the temperature of the bearing will rise rapidly due to the lack of oil in a short time and damage the bearing. In addition, the current vibrating screen bearing adopts grease lubrication and labyrinth sealing structure, the sealing space is usually 1 to 2 mm, but in practical applications, with the increase in bearing temperature, the viscosity of the lubricating oil is gradually reduced, the spindle is rotating at high speed, and the lubricating oil in the labyrinth cover is constantly leaking from the labyrinth cover, resulting in the bearing being damaged due to lack of lubrication.
Treatment: If the customer has a bad oil seal seal, in the absence of relevant oil seal inventory, please contact the sales department of crusher parts of our company at the first time, we will prepare the supporting oil seal for you as soon as possible.
Third: When the circular vibrating screen is maintained, the butter supply is not suitable. The circular vibrating screen produced by Shandong Sanxiang Heavy Industry machinery is different from the company's existing thin oil screen and three-axis elliptical screen, it uses butter, high viscosity, when workers carry out daily maintenance, we must pay attention to whether the butter is in place through the oil hole observation. If the lack of butter causes the problem of machine cylinder pulling, it should not be.
Treatment method: Check the use of circular vibrating screen bearing butter regularly, if there is a lack of butter to make up the shortage in time. Under normal circumstances, in the case of no lack of butter, the bearing of our machine is not easy to damage.
In summary, Shandong Sanxiang Heavy Industry Co., Ltd. in the face of circular vibrating screen bearing damage, generally in line with the work attitude of seeking truth from facts, and actively help relevant stone crusher customers to analyze the reasons and solve the problem. Indeed, it is caused by the quality problem of the parts of the crusher series products. We will help customers replace the new parts. If it is caused by the customer, our Shandong Sanxiang Heavy Industry machinery is also the first to help customers deal with the problem, but the relevant maintenance costs need to be borne by the customer.
