The service life of the bearing: the main failure mode for high-speed bearing

Ball bearings, cylindrical roller bearings cylin - Methyl amino acetonitrile dricalrollerbearin - Methyl amino acetonitrile g roller is a centripetal roller bearing cylindrical roller. Ball rolling bearing so for bearing detection, it is very important, analytical direct contact with the outer ring of bearings and wheel part mainly play a supporting role. Many motor manufacturers by adjusting the bearing cover inner cavity depth, increase the bearing oil baffle plate, baoding rotor alignment degree to reduce the motor rotor running in the process of dynamic operation and adjust radial fit tolerance of bearings and related parts and see the obvious effect. Insulation advantages of bearing inner ring or outer ring to add special spraying technology on coating insulation bearing, the bearing's outer surface plating quality coated, coated adhesive strength with substrate, insulation performance is good, can avoid induced current galvanic action of bearing, to prevent current grease and rolling element and raceway damage, improve the service life of bearing. If is bearing of complete sets of equipment, in the process of selecting the lubrication method, should fully consider other parts of the lubrication method and characteristics, as far as possible the adoption of the same model or with a variety of lubricant, in running, so can reduce a lot of running costs. Bearing grinding CNC numerical control technology in high speed and low speed can guarantee accuracy, can complete jump, fast, finishing compensation, coarse to fine grinding, make the machine tool feed mechanism is greatly simplified, greatly improve the performance reliability. Wheel hardness is too high; , in the face of the fan vibration causes, specific to resolve, such as impeller corrosion, wear, dust caused by vibration must be disassembled to repair. Rolled the captain the use of the time, due to bearing a wear loose bearing and axial movement, with the increase of test bearing a wear, bearing gland of the bearing of impact and damage, at the same time bearing in bearing under the shock, vibration and metal loss caused by roller machine can't run, causing unplanned downtime to suspend production. Pit ball or roller, about bearing grease used in the rolling bearing grease, is composed of lubricant and thickener, also containing a solvent and quantitative additives. & emsp; & emsp; Introduction of accident & amp; emsp; & emsp; Found on a wind farm in the background software units 'generator speed' down, then triggers the 'generator bearing temperature on the high side', 'generator bearing temperature is too high,' multiple failures. Using artificial grinding process is difficult and repair for a long time, in the face of such devices, its bearing wear is also very common, a few with several: common. - Mm, bearing ( Double disk) , axial fixation for shaft end pressure ring, cylinder diameter, besides can bear radial load, the bearing can withstand two-way axial load.
