Micro bearings: transmission bearing wear how to confirm

Ball screw support bearing dust ball screw with rolling bearings, and (if Chip clastic) Enter will soon make it wear and damage. Sauvy industrial boiler fan bearing a carbon nanometer polymer materials to repair steps: according to the situation of boiler blower trunnion sizes and wear determine sauvy tooling process, site operation steps are as follows:. ） ； Mobil half barrel; Angle grinder; Sand paper several; Flat to down size each; Torque wrench NM - NM） And with matching set of head; Of the instrument; The tooling/set; The tape measure; Connection with screwdriver, wire clamp, diagonal cutting pliers. Good poor lubrication of the bearing lubrication of the bearing rust, sealing, cooling, and plays an important role, such as ease, fatigue life of bearing, wear has a great influence, temperature, vibration, friction, etc. When filling Angle exceeds °, the device will compare difficult, as under RPM speed of the motor mostly adopts CM clearance, such as high temperature and high speed motor, require the use of relatively large clearance. In bearing before installation, if need to add grease in the bearing, oil must be cleaned, right amount, usually users should put the bearing into the heated to ° - in mineral oil ° immediately when loaded on the spindle. : is the purpose of cleaning, for small motor, up and down the shaft extension end of rotor to move by hand, if the rotating shaft can have bigger activity, bearing wear. Grinding wheel pendulum is too big, due to the grinding depth constantly changing; , this kind of method is widely used, as rotating equipment installation accuracy can meet the requirements, coarse grinding workpiece too deep, fine grinding allowance is too small, no wear off; Deviation map, rotating equipment coupling variation situation analysis diagram as shown. Products bearing column groove clearance try to control the difference of each other and the process has been improved, insulation bearing, in the outer or inner ring surface of microns thick layer of coating, can withstand high voltage VDC. The other aspect, the fire roasted coupling and coupling guard shell for a long time in the burning organic matter can also produce heat, combined with the coupling cover half burned a damaged condition, etc. , so as to make the fire present age small phenomenon. Again because of friction hot forming of high temperature, lubricant can form aldehyde, ketone and carbonic acid, the product will also react with the material, so the friction corrosion not only damage the surface of the parts and will also reduce the contact fatigue strength of parts. It is mainly used to bear radial load, also can bear axial load, outer ring are carry penal single row bearing can be smaller under constant axial load or larger intermittent axial load.
