Slewing bearing is widely used. Construction machinery is the first and most widely used place of rotary support, such as earthmoving machinery, excavator, disintegrator, stockpiling and retracting machine, grader, roller, dynamic rammer, rock drilling machinery, roadheader, etc.Other concrete machinery: concrete pump truck, concrete mixing cloth rod all-in-one machine, belt feeder feeding machinery: disc feeder, sand mixer;Lifting machinery: wheeled crane, crawler crane, gantry crane, tower crane, fork crane, crane, gantry crane;Ground treatment machinery: impact reverse circulation drilling machine, rotary drilling machine, impact rotary drilling machine, rotary rotary drilling machine, reverse circulation rotary drilling machine, positive circulation rotary drilling machine, long spiral engineering drilling machine, diving engineering drilling machine, static pressure pile machine, pile driver;Engineering ship: dredger;Special vehicles: bridge inspection vehicle, fire truck, window washer, flat plate beam carrier, aerial work vehicle, self-propelled aerial work platform;Light industrial machinery: beverage machinery, bottle blowing machine, packaging machine, filling machine, revolving bottle sorting machine, injection molding machine;Marine crane: floating crane.

The two common solutions to slewing bearing noise, dust and scar, are as follows:

(1) Control method of dust sound

There are dust and other foreign bodies in the rotary branch, non-periodic vibration will occur, the so-called dust sound, its vibration and noise size is uncertain, and or or no.

The control method of dust sound: improve the cleaning method of the slewing support/rotary plate bearings, and clean the bearings, shafts, seat holes and matching parts strictly before installation;Remove foreign matter in the lubricant;Improve bearing seal;Avoid plastic retainers with impure materials or embedded foreign matter.

(2) Control method of scar sound

Rotary bearing rolling surface such as a crack, indentation, or corrosion will occur like rivet rivet cyclical vibration and noise, the cycle may be fixed but mostly, the corresponding relationship between speed into a scar on the channel occurred in a row, scars on the ball, and the noise with the installation and lubrication condition and have certain changes.The control method of this kind of noise: the bearing shall not be struck during installation, and the bearing shall not be inclined when it is assembled with the shaft and then loaded into the bearing seat;Prevent bearing corrosion and impact vibration during storage;Use a grease with high viscosity.(3) Noise caused by lubrication factors and countermeasures Wrong choice of lubricant, insufficient lubricant or aging hardening can lead to vibration and noise of the slewing support/rotary disk bearing, and such noise does not have a certain rule.In this case, only select the appropriate lubricant, adjust its lubrication dose, prolong the service life of the lubricant and reasonably determine the replacement period.

(4) Noise related to the main engine and countermeasures

This kind of noise is not caused by the bearing alone, so it is invalid to look for the cause from the bearing alone. The main engine should be paid attention to comprehensively, and the performance of the main engine should be improved if necessary.This paper mainly describes the common beep and frame resonance in the motor.A Motor’s beeping and Its Countermeasures The axial vibration of the motor’s shaft will cause A very high frequency noise — beeping, whose frequency is the same as the axial vibration frequency and can be invariant or variable.The prevention of buzzes is the same as the prevention of axial vibration.B Resonance sound of Bearing Bracket and Its Countermeasures When the axial inherent vibration of the outer ring mass system mentioned above causes the axial bending natural vibration of bearing bracket, a kind of noise called resonant sound will be generated accordingly.By increasing the preload, the axial natural frequency of the outer ring mass system can be increased, the resonance condition can be destroyed and the noise can be reduced.
