Cylindrical Roller Bearing The Noise
Cylindrical roller bearing noise is a cylindrical roller bearing itself, that is, cylindrical roller bearings inherent noise; the other is cylindrical roller bearing installed after the noise generated, and cylindrical roller bearing itself has nothing to do with the noise. Cylindrical Roller Bearing A) Noise related to the manufacture of cylindrical roller bearings: including cage noise and tremolo, cage noise mainly occurs in ball cylindrical roller bearings and tapered roller cylindrical roller bearings, When the cylindrical roller bearing rotates due to the vibration of the cage and the impact of the cage and the rolling body will sound. This sound has a period of time. Vibrato (various cylindrical roller bearings) is a certain frequency of sound, B) inherent noise: raceway sound: the raceway sound is caused by the elasticity of the rolling body in contact with the raceway. When the cylindrical roller bearing is rotated, the raceway sound is caused by the vibration caused by the large waviness of the road surface. , Cylindrical Roller Bearing The rolling body rolling on the raceway and issued a continuous and smooth sound; abnormal rolling friction sound can be issued "creak, Cylindrical Roller Bearing creak" and the like uncomfortable metal friction abnormal sound , When the lubrication is good will not issue such a sound, so in general, is not a problem, only after the increase in noise to pay attention. C) noise caused by improper use: for a variety of cylindrical roller bearings are present.When the cylindrical roller bearing raceway surface or rolling surface by bumps, pressure pit, rust, then there will be a certain period of noise and vibration When the cylindrical roller bearings in the operation of dust intrusion will produce dirt noise. This noise is aperiodic, Cylindrical Roller Bearing also accompanied by vibration, the sound size is not fixed, sometimes without.
Cylindrical roller bearings vibration of the cylindrical roller bearing failure is obvious.For example: peeling, indentation, corrosion, cracks, wear and tear will be reflected in the cylindrical roller bearing vibration detection, so by using a special cylindrical roller Bearing vibration measurement device (frequency analyzer and vibration meter, etc.) can measure the size of the vibration, the frequency distribution can be inferred from the specific circumstances of abnormal vibration, the measured value due to the use of cylindrical roller bearings or sensor installation location and so on Different, Cylindrical Roller Bearing so the need for prior measurement of each machine after the analysis and determination to determine the criteria
Normally, the temperature of the cylindrical roller bearings is gradually increased as the operation starts and reaches a steady state after 1 to 2 hours The normal temperature of the cylindrical roller bearings varies depending on the heat capacity, heat dissipation, speed and load of the machine. Inappropriate, Cylindrical Roller Bearing the cylindrical roller bearing temperature will rise abruptly, there will be abnormal high temperature, then you must stop and take the necessary precautions.
Lubrication on the rolling cylindrical roller bearing friction and wear, temperature rise, vibration and so have an important impact, there is no normal lubrication, cylindrical roller bearings can not work. Analysis of cylindrical roller bearing damage causes that about 40% of the cylindrical roll Sub-bearing damage is related to poor lubrication, so good lubrication of cylindrical roller bearings is to reduce the friction and wear of cylindrical roller bearings effective measures.In addition, the cylindrical roller bearing lubrication also on the heat, rust, seal , Cylindrical Roller Bearing To ease the impact of such a role.To ensure that the lubricant can not expire failure, the selection to be correct. Harvester cylinder roller bearings lubrication lubrication and grease lubrication two.
