Gear box bearing chamber wear reason and repair cases

Gear box in industry is very common, and the gearbox bearing chamber of wear is incurred gear box can not continue to work normally, the common problems of in order to let everyone have a good understanding, China bearing network was introduced to make the cause of the wear of gear box bearing chamber, and to make repair case, hope to be of assistance. Gear box bearing chamber wear reason: bearing chamber wear reason is mainly due to the bad working conditions, in the process of long-term operation, the bearing outdoor table bearing outer ring of the extrusion pressure and the effect of compound mechanical force, deformation for sex. But poor concession of metal material, easy to form fit clearance, if not found in time and take measures, will form the gap from time to time extension, form directly bearing chamber wear. Another clutch of continuity in the process of the equipment work work, make the input shaft mechanical stress continuity not average, easy to form the bearing outer ring rotation by bearing chamber wear, constitute a vicious circle. Wear online repair gear box bearing chamber case: equipment data: the reducer is on, middle and lower three layers of structure, output shaft is spread up and down. Title of equipment: cold rolling machine Lord reducer; The input speed: 0 - — 500/1200r /分钟; The reduction ratio: 2. 92/1. 513; Bearing model: 24152. Cold-rolled main reducer gear box has its particularity in consumption process operation, two opposite direction of output shaft in synchronous rotation, transfer roll in the process of consumption to the impact of the force and torque are quite large, the condition of bearing chamber to accept extrusion pressure is big, easy to form the eccentric wear. The maintenance technology is applied on the mechanical properties of the carbon nano polymer material characteristic and the corresponding repair process online repair, including various types of reducer, or large axle shaft hole of the wear and tear. Repair process is simple: the unworn to restore the original specification size and wear parts diameter size. Maintenance technology advantage is good, stick relay with good pressure resistance, abrasion resistance and have metal comprehensive mechanics performance of elastic deformation, etc, can be completed online repair, repair of high efficiency, - As a condition of a single bearing chamber can be 8 hours to complete the repair. Carbon nanotubes polymer material similar to a cold welding technology, on-line repairing process does not produce heat, can very good maintenance equipment ontology from damage, and in the process of repair is not restricted by uneven wear amount. Polymer materials in the process of using carbon nanotubes will not produce metal fatigue wear and tear, in normal maintenance under the premise of care equipment, its use life and higher than that of the new parts after the restoration of life. Had many advantages, such as low comprehensive repair capital to the enterprise equipment maintenance maintenance provide powerful processing plan, can significantly reduce the consumption of enterprise capital. Repair of cold rolling mill reducer gear box bearing chamber wear steps are as follows: ( 1) Overhauling the gearbox parts, confirm the bearing chamber wear state and wear volume; （ 2) With the oxygen acetylene flame to the bearing chamber to stop baking oil disposal; （ 3) Use polishing machine will stop to repair the bearing chamber of burnish disposal; （ 4) With anhydrous ethanol for the grinding of bearing outdoor table stop cleaning; （ 5) In accordance with the proportional and carbon nano polymer materials SD7104; （ 6) In the repair parts coated carbon nano polymer materials SD7104; （ 7) With blade feet along the datum blade coating carbon nanotubes polymer materials forming; （ 8) Carbon nanotubes polymer materials with iodine tungsten lamp SD7104 stops heating curing; （ 9) Using the new bearing to fix the bearing chamber stop grinding show points and remove high; （ 10) In bearing indoor appearance secondary carbon nano polymer materials SD7104 daub; ( 11) In the bearing outer ring tuomoji SD7000 daub; ( 12) Back pack each gear shaft parts, gear box body; （ 13) Boot operation.
