Full ball bearings: how to realize the two-way cross roller bearing positioning

To mill taper bore column TQIT cone bearing as an example, the bearing inner ring is divided into two parts, two single ring and the middle of a double inner ring, a oil hole at the end of the roll and corresponding identification which is correspond to the inner ring, outside is corresponding to the middle of the double inner ring, corresponds to the inside diameter of inner ring. Traditional car wheel with bearing is combined by two sets of tapered roller bearings or ball bearings, and the installation of the bearing, oil seal and clearance adjustment is carried out on the auto production line. And will be out, entrance pipe wall, in case of debris fell into the low, based on the degree of used oil, viscosity, water and pollution index changes, on time and qualified gas and oil change. The first kind of circumstance, the iron bearing chamber, it is recommended that you check with the bearing chamber, the question was much easier than the above, mostly with loose! According to some bearing ( NSK SKF) Information is introduced: the bearing outer ring and the degree of the bearing chamber with bearing ring to indoor creep in bearing, get the uniform makes the bearing outer ring so wear and prolong the service life of bearing, excuse me reasonable? A: you said, is refers to the axial creep, the peristalsis is to absorb the axial expansion. Sauvy carbon nano polymer material has the adhesion, excellent comprehensive properties such as compressive strength, can live from removed from machine repair, also can remove the machining repair, no repair welding thermal stress effect, repair the thickness is not restricted, and the product of metal materials do not have rolled back, can absorb the impact of vibration equipment, avoid wear and tear, and greatly prolong the service life of equipment components, save a large amount of downtime for the enterprise, creating huge economic value. So the oil standard label is not correct to mislead inspection maintenance personnel, after analysis the cause of this accident is high speed spindle bearing inner oil return hole is too low, tubing over most of the oil directly from the oil orifice flow back into the reducer. Bearing damage, resulting in bearing chamber after wear ever caused wear, manufacturers can choose to replace, but some smaller enterprises to adopt to wear pads copper sheet and grinding point to quick fix is resumed production. Should replace the shaft, or car straight set ( Heat set) , surface treatment: the first will wear position baked oil processing, remove oil seep into the metal microporous; 。 Why, then, oil-free bearings are widely used? The following way to know! Oilless bearing advantages as is known to all, all the smooth running of the machine using a bearing. So in order to shorten downtime, reducing frequency of material apply, we first according to the wear of bearing high processing size thickness for mm shaft sleeve ( See figure on the shaft sleeve and then use the material to repair parts, with a pin sleeve is fixed to the shaft and shaft sleeve again after rub material assembly mould ( See figure for dimensional accuracy. HRC, the results are shown in table, in the wave generator turns, corresponding with the long axis direction of soft wheel teeth gritting is squarely into the first round of internal tooth; In the short axis, the teeth in the full release. The traditional repair welding machine repair technology facing the same problem on site was unable to complete repair, repair cycle is long, the comprehensive cost is high, long downtime shutdown will cause huge economic losses to the enterprise.
