A continuous beep "buzz.":
Analysis: Motor no-load operation is issued a similar buzz sound, and the motor axial abnormal vibration occurs on or off the "hum" sound.
The specific features: multiple lubrication condition is not good in winter, and both ends of the multiple ball bearing mot or, the main axis aligning performance is poor, under the influence of axial vibration, the vibration of an unstable.
The solution: lubrication properties, good fats; B, plus pre-load, to reduce installation errors; the selection of radial clearance of bearings; D, improve motor bearings rigid; strengthen the bearing tone Mind.
Note: The fifth point play a fundamental improvement, and 02 minor groove curvature, the curvature of 01 major groove.ball bearing companies
2 lacquer rust:
Solution: the rotor casing, drying or drying after assembly; B, reduce motor temperature; selection to adapt to paint models; D to improve motor bearings placed in the ambient temperature; E, with adaptation of grease, fat caused by corrosion, silicone oil, mineral oil is the most easily cause; the F, vacuum dipping process.
Analysis: Because the motor bearing chassis Paints dry, volatile chemical com position of corrosion of the bearing face, the outer channel and the channel, so that abnormal sound channel corrosion.
Specific characteristics: corrosion of the bearing surface rust is more serious than the first side.ball bearing suppliers

A lot of experience in mechanical maintenance technicians usually by mechanical operation of the voice to determine whether the device is normal, Tianjin Han Huang Seiko Trade Co., Ltd. technical staff past experiences to the sound of the motor bearings for example analysis.

3, bearings feel bad:
Solution: A clearance as much as possible to be small; B the choice of the tolerance zone; improve accuracy, reduce the damage of the channel; D, grease selection
Cause Analysis: A clearance is too large; B, the inner diameter of shaft mis-match; C-channel damage.
Specific characteristics: the rotating rotor grip bearings are beari ngs inside the impurities block sense.double row bearing

4, heating up:

5, to maintain Acoustic "Hey Lee Hey Lee ...":

6 impurities sound:
The solution: choosing the right fats, the appropriate dosage; correction clearance preload and cooperate with, check the free end bearing functioning; to improve the bearing accuracy and installation methods; D to improve the seal in the form.
Specific characteristics: the bearing operation, the temperature is outside the required range.
The solution: A selection of good fats; greasing before cleanliness; C and strengthen the bearing seal performance; the installation environment cleanliness.
Specific characteristics: Sound sometimes even without varying rules, multiple high-speed motor.
Cause Analysis: A grease too much lubricant resistance increases; B, the clearance is too small cause internal overlo ad; C installation error; the friction of the sealing equipment; E, bearing reptiles.
The solution: A, to improve the retainer fine; selection of travel gap small bearings or the bearing pre-load is applied; C to reduce the torque load, reduce installation errors; D, selection of good fats.
Analysis: caused by the cleanliness of the bearings or grease, issued an irregular abnormal sound.
Analysis: by the retainer and the rolling-body vibration, shock generated grease types are likely to produce, to withstand the torque, load or radial clearance when more prone to.

7, high-frequency vibration sound "da da ...":
The specific features: sound frequency varies with the speed of the bearing parts of the surface waviness is the main reason that caused the noise.
Solution: to improve the bearing raceway surface quality, reduce the waviness amplitude; B, to reduce bruising; C correction clearance preload and cooperation, to check the func tioning of the free end bearing, improve the accuracy of shaft and bearing installation method.
