Belt conveyor roller bearings remove steps and remove tool

Belt conveyor roller bearings 2020 - remove steps and remove tools 11 - 12 a tail mine belt conveyor belt was the main role of the reversing drum, its structure is shown in figure 1, poor working environment, high speed, heavy load, long wheelbase. If the lubrication is not timely or leak can cause bearing, such as color, and then burned to death. How to quickly and easily when overhauling the replacement bearing is very important. This article to share belt roller disassembly and improve efficiency and quality of the methods and tools. Figure 11. Analysis of present status of disassembly method is: (1) the first end cover removed and nut. (2) the use of hydraulic jack or first copper bar shaft and a plate of the bearing will be removed out ( Stress points on a shaft shoulder) 。 (3) the use of copper bar or a sledgehammer to strip the wood from the other side of the drum percussion bearing opening another plate of bearing outer ring. The disadvantages of such removal methods mainly using spherical roller bearing rollers, between outer ring and roller bearing for surplus to cooperate, rolling element can be reversed ( As shown in figure 2) Make inner ring, cannot use normal disassembly tooling, operators in the bearing outer ring with the strip wood support as a stress point, with copper bar or frequent hammer percussion, unbalanced stress points, must be changed frequently position make its uniform stress, need a few people took turns to exchange with a hammer. At the same time due to the bearing by frequent impact, bearing damage easily. Figure 22. Efficient and fast disassembly method and equipment design for belt conveyor roller structure and the use of the characteristics of the spherical roller bearing, using the double pressure plate and support plate and hydraulic jack made the disassembly scheme in figure 3 below. Figure 33. The practical effect of use the belt tail roller bearing down the tooling and verified by field use ( As shown in figure 4, figure 5, figure 6) , but with a flexible product adjust the position of the support plate and the pressure plate to meet the needs of different types of disassembly, able to gm; Simple and convenient operation, safe and reliable, high efficiency. Figure 4 figure 5 bearings bearing as before disassembly center 6 bearing removal after the traditional method of removal efficiency is low, remove a plate bearing need three operators work about 30 minutes, and bearing a frequent punch, bearing cage is easy to damage, influenced by artificial factors, it is difficult to ensure the quality. Using this method and tooling to remove only need two operators work for 10 minutes to complete, at least a 78% increase in production efficiency, the labor intensity of operators greatly reduce; Simple and convenient operation, safe and reliable. The scheme adopts the hydraulic jack bearing load evenly, can guarantee the quality of removal after the completion of the bearing.
