The solution of slewing ring bearing noise

   Slewing ring bearing noise common to have two kinds of dust acoustic sound and scars solution is as follows:
   (1) The control method of the dust acoustic
    Rotary branch within the dust and other foreign matter, non-periodic vibrations occur, the so-called dust acoustic, vibration and noise uncertain size, and with or without.Sound dust control methods: improving the cleaning method slewing ring / turntable bearing, the bearing before installation, shaft, housing bore all the rigorous cleaning and matching parts clean; remove foreign objects inside the lubricant; to improve angular contact ball bearing seals; avoid the use of impure material or a foreign body embedded plastic cage.
   (2)The control method scars sound
    If slewing ring rolling surface cracks, indentations or corrosion occurs as a rivet as periodic vibration and noise, the cycle may be fixed but most of the speed of a certain relationship, the scars on the channel will be continuous occurs, wounds hidden when on the ball, and this noise and there are some changes with the installation and lubrication conditions.
    Such noise control method: When installing not knock bearing, the bearing and the shaft bearing assembly before loading to prevent loading ramp when the bearing; when the stock to prevent shock and vibration to prevent bearing corrosion and transport; the use of high viscosity grease .
   (3) Noise and Countermeasures lubrication caused by factors Lubricant selection errors, lack of lubricant or the occurrence of aging sclerosis, can cause slewing ring / turntable bearing vibration and noise, and this noise is not necessarily the rule. In this case, only the choice of a suitable lubricant, lubricant adjust its volume, extend lubricant life and reasonably determine the replacement cycle.
   (4) the noise associated with the host and Countermeasures This noise is not simply caused by a handpiece bearing

, and thus to find a single reason from the bearing areas is ineffective to deal with a host full attention, to improve the performance of the host when necessary. The main narrative is now common in motor beeps and rack resonant sound.
