Slewing ring bearing noise solution

Slewing bearing noise common with dust and scratches acoustic sound two solutions side as follows:
(1) dust control method sound, there is support within the rotary dust and other foreign matter, non-periodic vibrations occur, the so-called dust acoustic, the size of the vibration and noise uncertainty, and with or without. Dust acoustic control method: the cleaning methods to improve slewing ring / wheel bearing, front bearing installation, shaft, housing bore and mating parts all in strict cleaning clean; remove foreign matter within the lubricant; to improve the bearing seal; avoid the use of impure material or embedded foreign objects plastic cage.
(2) control method scars sound, slewing ring rolling surface if crack, indentation, or rust occurs like a rivet as a periodic vibration and noise, the cycle may be fixed but mostly related to a certain speed correspondence, scars continuously occur on the channel, the scars on the ball on time is now hidden, and this noise with the installation and lubrication conditions and there are some changes. Such noise control method: When installing non-percussion bearing, the bearing and shaft assembly before loading ramp bearing to prevent bearings mounted when; when the inventory to prevent shock and vibration to prevent bearing corrosion and transport; the use of high viscosity grease .
