Thin-walled deep groove ball bearing causes of noise is more complex, one is the bearing inner and outer surface wear.
Due to the wear and tear, damage to the bearings and shell, bearing and shaft cooperate relationship, lead to axis deviation from the correct position, when axis at high speed movement produces sound.
When the bearing fatigue, its surface metal flake, also can make thin-walled deep groove ball bearing radial clearance increases produce sound.
In addition, the bearing lubrication, forms the dry friction, and bearing broken etc all make abnormal noise.
Bearing wear loose after kuang, maintains a looseness damage, also can produce sound.
Thin-walled deep groove ball bearings will be removed when checking, with photography method such as first and then record the appearance.
In addition, to confirm the amount of residual lubricant and lubricant sampling, and then clean the bearing.
A, bearing cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame.
B, rough washing, oil using a brush to remove grease or adhesive.
If at this time in oil rotating thin-walled deep groove ball bearings, pay attention to the rolling surface due to foreign bodies such as damage.
C, fine cleaning, slowly rotating bearings in the oil, must be carefully.
Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc.
No matter use which kinds of detergent, often should filter clean.
