Roller press bearing a repair of the application of new technology - bearing knowledge

Roller press is designed according to the principle of material bed grinding equipment, although expensive, but because of the energy utilization rate is high, so in the cement, steel, mining and other grinding has been widely used in industry.     Due to the manufacturer, extrusion method and transmission structure is different, combined with the use of various factors, roller press bearing wear will be increased. When choosing equipment enterprise at the very beginning, often combined with enterprise's economic situation considering the purchase of equipment and cost but neglecting the actual operation of the equipment value, which is one of the main reasons for the failure rate increases.     In the cement industry, for example, roller press bearing wear is a common problem. Once the wear reaches a certain degree, bearing pressure plate bolt fracture phenomenon appears frequently. For a long time, in view of the roller press shaft wear repair most used to return factory repair, not only long time and high cost, more important is the prime time in the cement market as soon as possible after damage, the damage is huge. This also with the intention of the enterprise.     Based in the United States and worked for the military and aviation services in the field of carbon nanotubes polymer materials technology, be sauvy industry in equipment remanufacturing in service with the introduction of high-end manufacturing again played a major role, also opened the device manager of the inherent thinking, how to use the new technology in the rapid development of modern industry, and many managers need to rethink the question.     Mentioned in carbon technology of polymer materials, is the first among the current innovation technology. Today is repaired with roller press bearing wear to brief sauvy industry of new technology.     1. Repair the principle & emsp;   Advantage of the characteristics of roller press shaft, rear axle shoulder datum as the location, at the same time, according to the bearing of the taper ( Usually a 1:12 and 1:30) Model feet, to make the processing standards. Using the template rule as repair tools, determine and measuring of the concentricity of repair and taper size, meet the requirements of new parts and bearing assembly. At the same time can guarantee more than 95% of the surface with requirements after repair, than the new parts with large area nearly doubled, the better to meet the requirement of stress, and most recently used.     Currently USES sauvy industrial technology to repair the roller press have hefei institute of maxhine HFCG180 - The type 160, chengdu lijun CLF180 - 120 - D - SD, citic heavy industries PR170 - 120, hefei institute HFCG160 - 140, hefei institute HFCG160 - 120, hefei institute HFCG150 - Fly PFG140-100, jiangsu peng 80年,HFCG140 - Type, citic heavy industry PR120-50 , chongqing GYJ140-80 The type 65, etc.     2. Sauvy industrial technology advantages & emsp;   1) Comprehensive repair cost is low: on the premise of meet the normal operation of equipment, which can realize online repair;     2) Put less Labour: don't need to make a lot of equipment disassembly, only to dismantle the bearing and the bearing seat repair operation can be realized;     3) High efficiency: generally 24 hours to complete the repair, and start running;     4) Long service life: on the premise of normal equipment maintenance, as long as not remove or damage repair parts for human, its service life completely reach even exceed the service life of the new parts.     3. Roller press bearing a wear repair construction standard & emsp;   1) According to the drawing size precise processing model feet;     2) Bearing surface baked oil, grinding processing, to ensure the surface dry and clean coarse;     3) Use sample feet of accurate positioning, ensure concentric;     4) Coated carbon nano polymer materials, install the bearing, and then control prestressing quantity;     5) Dismantle the bearing material after curing, remove excess material;     6) Bearing installation, control the bearing clearance and preloaded after installation.     4.
