150 - at the site Wear roller press bearing 90 steps - bearing knowledge

Some cement enterprise a rolling machine because of the cycle is long, because the technology is fatigue wear and the cause of the problem of daily maintenance, cause bearing bit wear. After initially appears roller machine wear, the enterprise was solved after removal off-line repair welding technology is the overall machining. Repair after the completion of the use process, bearing inner ring spinning problems remain, and lead to bearing wear again. After disassembly check found that only 20% of the surface and bearing inner ring bearing surface to maintain good contact, so the judgment in the process of machining accuracy is poorer, taper changed, cause the fitting surface is too small, leading to turn of bearing inner ring, causing further wear on the surface of the shaft. Recently, the company has 10 days repair cycle, the existing problems of roller press bearing inspection and repair. Due to the repair cycle is shorter, and enterprise for offline machining cycle and expenses, including machining precision, such as concerns, therefore decided to online repair. Enterprise through the understanding, interested in sauvy industrial technology comparison, also inquire about the application effect of the cement enterprises in the same industry at the same time, enterprises for sauvy industrial repair technology have more confidence, so in this background, decided to take sauvy industrial online repair repair technology. 150 - at the site Wear roller press bearing 90 case pictures are as follows: 150 - at the site Roller press bearing 90 steps sauvy industry according to the enterprise the abrasion of roller press bearing a first a detailed analysis and formulate corresponding repair plan, first ensure accuracy of repair, including the matching surface and concentricity requirements after the repair, at the same time, based on the operating conditions of a roller press bad carbon nano polymer materials, specifically meet the vertical mill under the bad environment needs long running work. On-site repair steps are as follows: 1. According to the size of the bearing a template rule; 2. Field measurement bearing wear quantity, calculate the amount of material; 3. Concentricity orientation, welding of anchor point, an empty test bearing inner ring, ensure the preloaded measurements; 4. Surface treatment, daub sauvy SD7101H carbon nano polymer materials, and then install the bearing inner ring, tighten to specified preloaded quantity; 5. Material after curing, remove excess material, then coated material again, will be bearing installed, at the same time, strict control in the process of the bearing clearance is installed; 6. Material after curing, boot operation, and periodically check and tighten bolts pressure plate. Conclusion: to sum up, sauvy carbon nano polymer materials in the repair of 150 - 90 roller press bearing wear problem repair with high efficiency, long service life, low comprehensive cost etc, to the enterprise equipment maintenance maintenance provide a powerful solution, greatly reduce the production cost of enterprises.
