Self-aligning bearing: tool steel and bearing steel

& emsp; & emsp; Generator bearing grease before too much is the root cause of the accident & amp; emsp; & emsp; For generator within the front bearing grease too much, just to for a long time to maintain combustion. If coupling surface coated with a thick layer of anti-rust paint, lacquer thinner should be used, and the type of fluid to soak, then wipe clean, besmear after the upper oil. Welding parameters using small specification, & amp; #; , such as needle roller bearing, some series of deep groove ball bearings, angular contact ball bearings, cylindrical roller bearing or spherical roller bearings and thin wall. Sharp, bond diamond grinding wheel dressing is bad; , clutch release bearing clutch are the signs of damage to the sound, not separation, leading to add and subtract the difficult or not directly into the file. Design reason, also because of the bearing ring wall is thin, bearing inner and outer ring is easy deformation, the inner ring guard can be used without slot structure, but to strictly control the seal clearance. Assembly or installation, such as bearing internal clearance is too large or too small, or in some cases, the preloading load is too high, can cause early damage and shorten the life of the bearing. Bearing assembly quality inspection method has two kinds: visual observation: after the motor end cover bearing chamber with bearing, turn the end cover by hand, if freely rotary bearing, flexible, no vibration and shaking up and down phenomenon, as a qualified. To turn, swing or speed is very low, n - Methyl amino acetonitrile r/min - or less Methyl amino acetonitrile) Bearing, is main failure form of plastic deformation, reason should be calculated at rated static load strength. This must be close to the hydraulic nut (piston position to install the right stop Figure oil injection method is more simple and easy method, but must use the set set with oil hole and the groove. If lambda is greater than that of oil film thickness is enough to separate two metal surface, lubrication effect is good; While if lambda is less than that of oil film thickness is not enough to completely separate the two metal surface and lubricating effect is not ideal. Said the two sets of A single row tapered roller bearing, installation, face to face with fixed distance between outer ring baffle, front axle bearing assembly to the clearance between microns to microns, after assembling clearance is zero. Main play the role of lubrication and sealing, bearing grease for the bearing ability to work with a lot of help, of course, we buy in bearing grease, if buy the bad products not only can't bearing lubrication effect, even for bearing of the damage, so a lot of people would like to know about bearing grease to identify the good simple method, according to understand, to share the following simple method, hope to be of help.
