There are 30 reasons for the bearing noise
Bearing is an important part of the speed reducer,sometimes the bearing will have noise.
The engineer from JiaYou REDUCER reducer made the following summary:
1.Grease contamination
2.Insufficient lubrication (the oil level is too low and the oil or grease can be damaged by sealing by improper preservation)
3.The clearance of the bearing is too small or too big (production plant problem);
4.The bearing is mixed with sand or carbon granule, which ACTS as abrasive
5.The bearing is mixed with moisture, acid or paint, which can be corrosive
6.The bearing is flattened by a hole. (the hole is not well rounded, or the hole is distorted.)
7.The underside of the underside of the bearing seat is uneven (leading to a hole deformation and even a crack in the bearing seat)
8.Bearing holes (residual chips, dust particles, etc.)
9.Eccentricity of sealing ring (touching adjacent parts and friction)
10.The bearing is subjected to additional load (the bearing is under a tight shaft, or a shaft has two fixed end bearings);
11.The bearing and shaft alignment is too loose (the diameter of the shaft is small or tight);
12.The clearance of the bearing is too small, and the rotation is too tight.
13.Bearing noise (the end of roller or the sliding of steel ball)
14.The heat elongation of the shaft is too large (bearing is subjected to the static axis to the additional load)
15.The shaft shoulder is too big (contact the seal of bearing and friction);
16.The shoulder of the seat is too large (the sealing part of the bearing is distorted);
17.The clearance of labyrinth seals is too small (friction with shaft)
18.The tooth of the lock washer (touching the bearing and the friction);
19.The position of the oil dump is not suitable (touching the flange cover and friction)
20.A hole in a ball or roller.Hammering the bearing with a hammer when installed
21.Bearing noise (external vibration source interference)
22.The bearing is heated and discolored (caused by the use of a spray gun to heat and disassemble the bearing)
23.The shaft is too thick to make the actual match too tight (causing the bearing temperature to be too high or noise);
24.The diameter of the seat hole is small (the bearing temperature is too high);
25.The bearing hole diameter is too large, the actual match is too loose (the bearing temperature is too high - the outer ring is skidded).
26.The bearing hole becomes large (the bearing hole of the nonferrous metal is enlarged or enlarged due to thermal expansion);
27.Stand fracture
28.Bearing roller is rusted.
29.Steel ball, raceway wear (the grinding is not qualified or the product has a collision).
30.Non-conformity (production plant problem)
