Bearing during operation, should be checked periodically according to specifications, painted with special hydraulic filling equipment, was carried out on the drive shaft universal joint cross shaft needle bearing lubrication on a regular basis.
A common cause of bearing temperature is too high, and large vibration: may be due to the coupling is not accord with standard of process, find rotor unbalance activity, poor foundation rigidity and the anchor, rotating stall and surge.
On-site repair ball mill bearings wearing application case of various structure types of bearings due to the different structural characteristics, can be adapted to the different conditions of use, designers can undertake choosing according to their own needs.
Cage cage breaking belongs to incidental abnormal failure mode, can through the proper preloading, improve lubricants and lubrication method, improve the accuracy of shaft, bearing box to solve.
Thickener is a mixture of sodium calcium soap and soap, drop point ~ ℃, penetration to mm, weak water resistance in calcium base grease, allow the water vapour or work in damp environment and working temperature for ~ ℃, not suitable for low temperature.
Bearing running clearance is smaller, with no load guide roller is, the better, the smaller the bearing noise at runtime, operation process, bearing wear and sink make clearance increases, but can compensate by pre load.
In the diagram above, after the unwrapped end cover, can see the bearing and the bearing outer ring ring, remove the bearing outer ring ring, because the bearing is heated up set of connection on the shaft.
The instrument features:, dirty jams cooler lubrication pipe cooler, will cause poor cooling effect, especially in the summer production, this problem is especially common, as the appearance of the bearing are two round ring, a lot of ball filled with middle, should choose the higher base oil viscosity (
ISOVG to or higher)
The grease.
If it is rotating equipment offset value measurement, select two and a half coupling end, according to the figure coupling equinoctial classification methods, such as turn ° from point to point position, check whether there is any change on the dial indicator pointer refers to zero if no changes can start measuring or parts checking.
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.
Within the family with good motor factory will H stand number in high voltage motor, from using a ball bearing, ball bearing, bearing a column, the running effect is very good.
Of rolling bearing and rolling body of inside and outside the circle should be has high hardness and contact fatigue strength, good abrasion resistance and impact toughness, as with chromium manganese high-carbon steel (
Pitting)
Manufacturing, commonly used material with GCr, GCrSiMn - bearing steel
Methyl amino acetonitrile, GCr bearing steel, bearing steel, GCr bearing steel, hardness is not lower than HRC - after quenching
HRC。
