Slewing bearings are widely used in hoisting machinery, mining machinery, construction machinery, port machinery, ship machinery and mechanical precision radar and missile launcher equipment such as large rotary device. At the same time also can according to customer's specific requirements of the design, development, production various special slewing bearing structure.
Slewing bearing noise common with dust and scarred two
solutions as below:
(1) dust acoustic control method
Reverse branch with dust and other foreign bodies, the
cyclical vibration will happen, the so-called dust, the size of
its vibration and noise, and with or without.
Dust acoustic control methods: improve the rotary
bearing/wheel bearings cleaning method, before installation
to bearing, shaft and hole and all parts to match the strict
cleaning clean; Remove the foreign body in lubricant; To
improve the bearing seal; Avoid the use of material is not pure
plastic cage or foreign bodies are embedded.
(2) the scars of noise control method
Slewing 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.
This kind of noise control methods: installation not knock when the bearings, bearing and shaft assembly after a load bearing seat when prevent bearing oblique; Inventory to prevent rusting bearing and transport to prevent impact vibration; Using high viscosity of grease.
(3) the lubrication factors caused by noise and its countermeasures
Lubricant selection error and lack of lubricant degradation and induration, can lead to rotary bearing/wheel bearing vibration and noise, and the noise without certain regularity. In this case, only to choose suitable lubricant, adjust its lubrication dose, prolong the service life of lubricant and reasonable replacement cycle.
(4) with the host about noise and its countermeasures
This is not a simple noise caused by bearing, thus single to find reasons from the aspects of bearing is invalid, dealing with host comprehensive attention, when it is necessary to improve the performance of the host. The main narrative in the motor common hum and rack resonant sound.
1. Motor hum and its countermeasures
The motor shaft axial vibration will cause a lot of high frequency noise, hum, its frequency and axial vibration frequency is the same, can is a constant change. Hum way to prevent and prevent axial vibration method is the same.
