Self-lubricating bearings, bearing clearance c0 and c3 distinction

So bearing installation need to pay attention to what issues? Before installation, radial load hours, choose deep groove ball bearing: radial load is big, the selection of cylindrical roller bearings. Self-aligning roller bearing plastic cage compared with stamping steel cage, the cost can reduce more than %; Plastic cage compared with brass keep slimming, cost can reduce more than %, has very obvious economic benefits. Figure bearing degradation is the first phase of the vibration signal characteristics in summary, as can be seen from the bearing degradation stages, the frequency and the faults of bearing fault characteristic frequency characteristic frequency are occurrence frequency doubling, whether any side frequency set the degree of degradation reaction of the bearing information, from the perspective of the relationship of frequency and time of bearing degradation has a tendency to move from high frequency to low frequency, the first change of ultrasonic frequency measured signal, with the development of bearing degradation, resonance frequency can be observed through analysis method of bearing fault characteristic frequency, low frequency signal within the KHz after observed on the power spectrum of the fault characteristic frequency. By the meshing between the release process in the recess action or meshes into state, basic deep groove ball bearings by an outer ring, inner ring and ball and cage constitute. Low thermal expansion coefficient is low, the use of should careful when installation, do not allow the powerful punch, are not allowed to directly with hammer percussion whole eccentric bearing, not allowed by transfer roller pressure. Usually adopt row cylindrical roller bearings bear radial load, thrust roller or thrust ball bearing and radial angular contact ball or centripetal roller bearing axial load, is now mostly used lubricating oil and gas or oil mist lubrication and grease lubrication cooling way. To understand the process, can automatically compensate for shaft deflection and alignment errors caused by casing deformation, suitable for supporting hole cannot be confirmed in the alignment of the parts. It is the right rear wheel bearing problems prompted a buzzing driving, this is the excelle tire screw! We can see the tire screw is modified. Low clearance code symbol meaning/radial clearance for group C/C radial clearance for group - — Radial clearance for the group, that is, common set of radial clearance for clearance/C/C radial clearance for groups/radial clearance for group C/CM for motor bearing clearance low vibration level code Z - — Bearing vibration acceleration level extremum categories, from low to high as follows: ZZZZV - — Bearing vibration velocity magnitude extreme value categories, from low to high as follows: VVVV configuration code symbol meaning DB installed back to back in pairs, example: C/DBDF installation, face to face in pairs: / DFDT series installed in pairs, example: C/DT bearing seal structure Z - — With dust cover bearing used in pollution is not serious and there's no water, steam and other contact bearing bearing configuration. Oil lubrication is to set pressure lubricating oil through in bearing side nozzle spray into the bearing lubrication for internal, as used in the high-speed roller bearing, or pressure lubricating oil can't meet the cooling requirements of the occasion. Bearing wear if very few, just to repair its geometric shape, but turning on a lathe, make the journal reach correct geometric shape, then the decrease of the corresponding bearing inside diameter. Response: replace new bearing, so it is necessary to seasonal inspection, intuitive is to watch the cell surface, look for any signs of a significant poles have saline or batteries.
