English: bearing tapered roller bearing the cause of the lock

Star elastic coupling left left universal coupling left left oldham coupling left left torx elastic coupling left left oldham coupling left left monolithic friction clutch left left multi-disc friction clutch left left electromagnetic friction clutch left left down the shaft left left chain structure left left chain left left down down down down down of rolling bearing left left left left the various types of bearings, self-aligning bearing due to the different design has different features. See appearance: grease regardless of what kind of pigments present appearance, fat body should have dense paste body, if you open the packing, see surface oil, grease, surface colour depth or skin sclerosis or consistency decreased significantly, or mixed with water and emulsion white fat surface, or grease on the surface of seal cause qualitative change, the fat are unavailable. & emsp; & emsp; When bearing severe card die before the shutdown command, through the actual power of the lower unit heat; When the machine stop load rejection speed rise up; After the stop command, bearing card died, still in the generator shaft rotation, severe friction bearing internal heat. Countermeasures: grinding trunnion, get appropriate coordination between the shaft and bearing inner ring, due to the material of bearing box hole stress after the aperture is too soft, cause the outer ring hole slippage in box. Some of the rotor in the process of running due to medium corrosion or wear and tear of solid impurities, or bent shaft, will lead to unbalanced centrifugal force, so that the bearing heating, vibration, roll the serious wear and tear, until the destruction. Contaminated by oil will make bearing temperature, in the process of grease into the dust, causing oil pollution, lead to internal oil degradation damage bearing lubrication bearing box, temperature rise. Improve assembly and method of use, bearing a irregular and uneven 'scrape' sound, the sound is due to the bearing inner into the iron filings, sand and other impurities. Root number of backup roll bearing force difference is smaller, the more the workpiece after pickling, when the surface wet, immediately under astigmatism lamp visual inspection, the normal surface homogeneously dark grey. For rolling bearing clearance shall not adjust, because of the radial clearance as defined by the standard in manufacturing has been good, can't adjust, such loading on the diameter of axle bearing or bearing hole, after the actual radial clearance is called assembly radial clearance, assembly time to assemble the size of the radial clearance is right to make necessary work in the operation of radial clearance, in order to protect the bearing flexible rotation. This type of spindle of the output power and torque than other types of much larger, but the trade-off, it's much more precision and stability is poor, so for this type of spindle, how to correct the machine tool spindle and its components design has a great impact on the machining accuracy of nc machine tools is. HG, and the needle into the small, the grease is too hard, not easy to completely fill the friction surface; Needle into the spend big, grease too soft, easy to leak phenomenon. Such as the inner ring and shaft neck usually cooperate, outer ring is inside the bearing assembly, assembly after retainer, retainer can make a roller to reduce the friction and wear and tear, that is why we use the cause of the rolling bearing, it is just because of the friction is small and not easy to wear and tear, so small steel ball is how to put it in? You first need to select and match the small steel ball size outer ring's inner circle.
