Which four bearings inside and outside: the structure of the rolling bearing components

Hope to deepen the understanding of bearing less understanding of the bearing, a recommended for normal operation of wheel bearings, interval - Hours added grease, with blade feet to wear surface as a benchmark, not for coating to restore original size; , don't think to do the lubrication will benefit self-aligning ball, not at all. Flexible coil heater heating temperature of the medium frequency induction heater setting must be less than c, because the bearing removal in need of quick temperature difference and the operating process, rather than temperature. Run heavy and temperature anomalies, may fall off because of the sliding bearing alloy, alloy scratch, bearing and bearing contact undesirable dry friction, etc. ; Or rolling bearings of rolling surface damage. And our family car use at ordinary times the load will not be very big, so use down to a normal family car, in to thousands of kilometers, probably will change of auto bearing. Fan as a fever, because air pressure is too high, workers in the operation process is often a accidentally met fan equipment, will make the fan air pressure changes, resulting in motor heating. So, reaming main play a role of bolt axial fastening bolt, sub station, have the effect of controlling the radial bearing, thus realized the vibrator and the axial and radial double constraints of the bearing. The outer ring ( Seat) Axis outerrin - Methyl amino acetonitrile g ( housin - Methyl amino acetonitrile gwasher) Axis if the outer surface of the outer ring is cylindrical, the outer surface of external cylinder axis is the axis of outer ring line, if the surface is spherical shape, basic by the external sphere sites on external surface of the ring, perpendicular to the line of the outer ring reference face, for the outer axis. If a ring should be full inspection after pickling, picking products, serious cannot repair or repair the unqualified should be scrapped, there is no grinding ring into the assembly process. If the size of the mat is not appropriate, also can match the B mill bearing cover, conical bore self-aligning roller bearing on the spindle after installation, make through nut bearing inner ring axial movement along the cone shaft neck do, bearing radial clearance adjustment. Bearing as the major parts of the mechanical equipment, its type and lubrication type is also has a lot of, mainly introduces relevant today insert spherical bearing lubrication type. Holding time to consider, heating conditions and status, the spherical connectors can make the trunk and the relative freedom of movement between the trunk and can chain on safely and reliably, but also make their swinging free. The question is, excavator wheel bearing ( Rotary bearing) Sound is bigger, in use process also has the sound of noise, this what reason is caused? According to the understanding of the wheel bearing, tell everyone in excavator wheel bearing ( Rotary bearing) The cause of the noise, and the corresponding solutions.
