Six items to avoid excavating machine wheel bearing noises

First of all, the bearing network inform you first what is the wheel bearings, wheel bearings can also be called slewing ring bearings, also known as rotary bearing most people. Like exploring on the wheel bearings, people often referred to as the rotary bearing a truth. Slewing bearing is a kind of comprehensive load can accept a large bearings, can accept the larger axial and radial load and tilting moment. Slewing ring bearing device with a hole in the ordinary gear or gear, smooth oil hole and seal installation, thus enable mainframe design compact structure, guide the tedious, easy to maintain. But the question now is, excavate machine wheel bearing ( Rotary bearing) In the process of using the sound of a match, also has the sound of noise, formed by what reason is this? China bearing network on the basis of understanding of wheel bearings, inform you incur excavating machine wheel bearing ( Rotary bearing) The cause of the noise, and the corresponding treatment method. At first we want to know, in the factory soon rotary bearing idling, emits an average noise of ball rolling, this belongs to the normal noise; If just device soon, present small sound does not matter, in turn the running-in period of time after the normal will die. We say today is like loud and match the special noise, in particular the noise of the demand note. Six items to avoid excavating machine wheel bearing noises: a device, the surface is uneven, bolt looseness in the present sound, demand is due to the problem device operation, when the device surface roughness can not reach the request, will form the raceway constitute a negative gap, resulting in a sound; When the gear mesh bad, also may produce sound, will thus formed broken teeth problems; In addition, when the device is loose, invite rotary bearing elastic deformation, deformation produces negative gap location, demand immediately stop check the bolt according to the request. Second, a foreign body slewing bearing slewing bearing internal such as sand, iron foreign body, will attack the periodic vibration, at the same time also with insensitive. When faced with this situation, the demand in front of the device will be bearing, axis, seat hole wash clean all parts and match the strict, timely eliminate the foreign body inside smooth agent; Remember that prevent the use of information is not pure or foreign bodies are embedded plastic frame, so do ability to remove the corresponding sound. Three fat, smooth problem form the sound of excavating machine rotary bearing adopts smooth smooth, smooth sound is likely to be due to the problem. Common causes include smooth roll passage for short fat fat, smooth filling is not even and smooth fat aging quality is poor, smooth agent choose wrong. If you want to deal with this problem, need to use appropriate smooth agent, filling in time, change can handle in time. Four, sealing strip breakage form sound check seals can wear, because the structure of the rotary bearing sealing strip plays an key role in sealing, when sealing strip and slewing bearing can't complete, easy to form a smooth grease leakage. In addition sealing strip material's resistance to aging and yellow oily, is also needs to think the problem. Five, crack, indentation, or rust formation of sound when the rotary bearing rolling appearance such as crack, indentation, or rust, also heard like rivet rivet periodic vibration, continuous attack scars on the channel, scars on the ball, and the noise with the device and smooth condition and have certain changes. Liberation is device not knock when the bearing or smooth fat of using high viscosity. Six, serious wear and tear of raceway and rolling element mining machine in the process of turning to render sound, is likely to be rotary bearing raceway and rolling body appear serious wear and tear, demand for rotary bearing stop maintenance of this evening. We all know, the excavation of the machine is compared to bad work environment, and the excavation of the machine wheel bearing ( Rotary bearing) Page ordinary work under large load state, slewing ring louder noise is a common problem, wheel bearing after the present noise also don't worried, we need to find the right reason, stopped processing can be targeted, more than six kinds of attention to matters of Chinese bearing network introduced and in view of the wheel bearing noise is common phenomenon, hope to be of assistance.
