Hot light machine bearing wear site repair field manual

In October 2018, the enterprise a hot light machine roller surface rendering large vibration in the process of consumption, site equipment management personnel arrangement to stop overhaul found that drive side bearing a present wear problem, because there is no adequate downtime nor the processing of solid wrist at the same time, under the request of enterprise equipment management to a stop after pitting at bearing assembly bearing way of emergency repair. Boot again two days later it is wear and tear, vibration value is more and more big, the enterprise again after removal of bearing pad of the copper foil way stop secondary emergency disposal, equipment operation after a day of present vibration again. Enterprise equipment management during the period after the Internet search to find and contact sauvy industrial technical engineers to stop communication for the equipment problem analysis, formulated the detailed repair plan. Due to the large equipment parts, the traditional way to laborious labor intensity effect also is bad, enterprises in deepening exchange and communication with sauvy engineer based on rapid affirms the collaboration, in order to ensure the using effect and resumed as soon as possible consumption, corporate resolution adopted sauvy carbon nano repair technology to stop the repair. At the scene of the first sauvy engineer equipment downtime to issue the work at the site for the device. Hot light machine drive side bearing wear problems and the reason analysis: hot light machine spindle transmission by use of 11 kw motor pulley, bearing type: 22220 ca; Bearing diameter: & Oslash; 100mm； The roll diameter: & Oslash; 350毫米; The device speed: 1460 r/min; Wear depth: 0. 6毫米; Roller surface temperature: 230 ° C; Bearing parts of the operating temperature of 80 ~ 100 ° C consumption to: 10 / d. Sauvy industrial carbon nano polymer materials to repair technology, the application of carbon nanotubes in polymer materials, unique mechanical properties with targeted repair technology, can repair all kinds of industrial equipment online axial wear problem. Repair process is simple: repair using the sauvy tooling repair process to ensure the concentricity, then the application of carbon nanotubes polymer materials SD7104 cooperate to repair the tooling complete bearing wear size of recovery, to that of the bearing inner ring to reach 100% of the mating surface. At the same time in the repair process to ensure the bearing pre-tightening, satisfy the bearing assembly interference quantity request, effectively prevent the existence of the clearance meet operation requirements. Sauvy carbon nanometer polymer materials technology field repair bearing wear steps: 1, appearance disposal: the wear of bearing a stop cleaning, grinding and other necessary disposal; 2, empty be on probation: the processing of repair tooling equipment in place, check the positioning dimension tolerance; 3, brush demoulding agent: within the repair tooling appearance brush SD7000 release agent; 4, harmonic, daub repair materials: severe harmonic sauvy carbon nano polymer SD7104 data in proportion, the average besmear to be repair of bearing; Harmonic sauvy SD7104 carbon nano polymer materials, fixed repair tooling: use the positioning pin to bolt tooling and fixtures after the stop position redundant data extrusion; 6, curing: room temperature cured with iodine tungsten lamp to repair the tooling and shaft neck to stop heating, the temperature control to the curing three hours below 80 ° C; After loosening bolts 7, remove the repaired tooling: remove the tooling and the surrounding stop eliminate redundant data; 8, bearing assembly: bearing with bearing heater stop heating expansion drive, hot charging bearing finish repair with lock nut fastening.
