Cylindrical Roller Bearing Requirements
In order to make the cylindrical roller bearings in good condition to maintain the desired performance and long-term use. Must be cylindrical roller bearings for inspection and maintenance, Cylindrical Roller Bearing inspection and maintenance is very important to prevent the failure, in the operation to focus on checking the cylinder Roller bearings rolling sound, vibration, temperature and lubricant.
When the cylindrical roller bearings performance indicators lower than the use of the requirements and can not work properly, the cylindrical roller bearings on the failure or even failure, Cylindrical Roller Bearing cylindrical roller bearings in the event of failure and other unexpected circumstances, the machine, the device will stop, appear Function loss and other anomalies, so need to identify the causes in the short term, and take appropriate measures.
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, Cylindrical Roller Bearing and the cylindrical roller bearing itself has nothing to do with the noise.
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, Cylindrical Roller Bearing when the cylindrical roller bearings rotate due to the cage Vibration and the impact of the cage and the rolling body will produce a sound. This sound has a cyclical. Cylindrical Roller Bearing Vibrato (a variety of cylindrical roller bearings) is a certain frequency of sound, is due to a large groove on the surface caused by the waviness Vibration generated.
Inherent noise: raceway sound: the raceway sound is caused by the rolling body in contact with the elastic characteristics of the raceway, when the cylindrical roller bearings rotate, Cylindrical Roller Bearing the rolling body rolling on the raceway and issued a continuous and smooth sound; Abnormal rolling friction sound can be issued, such as "creak, creak" and other uncomfortable metal friction abnormal sound, Cylindrical Roller Bearing good lubrication will not issue such a sound, so in general, is not a problem, only after the increase in noise to pay attention.
Noise caused by improper use: for a variety of cylindrical roller bearings are present.When the cylindrical roller bearing raceway surface or rolling body surface by the bumps, pressure pit, rust, then there will be a certain period of noise and vibration. Cylindrical roller bearings in the operation of dust intrusion will produce dirt noise. This noise is non-periodic, also accompanied by vibration, Cylindrical Roller Bearing 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, Cylindrical Roller Bearing the frequency distribution can be inferred from the specific circumstances of abnormal vibration, Cylindrical Roller Bearing the measured value due to the use of cylindrical roller bearings or sensor installation location and so on Different, so the need for prior measurement of each machine after the analysis and determination to determine the criteria.
