(1) Scars and their control measures
If there are cracks, indentations or rust on the rolling surface of a linear bearing
, periodic vibrations and noises such as riveting rivets will occur. The periodicity can be fixed but most of them have an inevitable corresponding relationship with the rotational speed. The scars will continue on the channel Onset, the scars appear on the steel ball from time to time, and this noise changes with the device and the smooth premise.
The control methods for this type of noise are: avoid knocking on the bearing when installing, avoid tilting the bearing when assembling linear bearings and shafts and then placing them in the bearing housing; avoid bearing corrosion when in stock and avoid shock and vibration during transportation; use high viscosity Smooth fat.
(2) The sound of dust and its control measures
There is foreign matter such as dust in the linear bearing, and non-periodic vibration and so-called dust sound will occur. The vibration and noise may vary in size, and may or may not be present.
The dust sound control methods are: improving the bearing cleaning method, before the device, the bearings, shafts, seat holes and matching parts are thoroughly and thoroughly cleaned; remove foreign matter in the smoothing agent; improve the bearing seal; prevent the use of impure or embedded data Plastic sticks with foreign objects.
(3) Noise caused by lubrication elements and its countermeasures
Incorrect selection of lubricants, lack of lubricants or aging hardening can lead to vibration and noise in linear bearings, and there is no necessary rule for this noise. Regarding this situation, as long as a suitable smoothing agent is selected, its smoothing dose is adjusted, the service life of the smoothing agent is extended, and the replacement cycle is reasonably determined.
