Spindle bearing FAG import how to maintenance and maintenance - bearing knowledge

A, spindle FAG import bearing performance and features: as a textile spindle bearing FAG import bearing, its structure is more special.
It USES no inner circle of single row centripetal short cylindrical roller structure, is the pure radial load under high speed precision bearing FAG import.
Integral FAG import after the assembly of bearing is still open state, considering the assembly, packaging, transport and the need of users to assemble, the spindle bearings mainly USES a special kind of anti-rust oil.
It not only has good rust resistance, but also can ensure the FAG import bearings in the final user when assembling part of scattered children is not easy to happen.
With single-row radial roller short circle, so the series FAG bearing rigidity is strong, big bear radial load;
Manufacture of high precision, rotating flexible, stable, low noise, to adapt to the high-speed operation;
Simple structure, low power consumption;
Maintenance is more convenient.
The spindle FAG import bearing series product standards are: FZ/T92025 -
1994 DZ series spindle bearing textile industry standards.
Adopt the new reinforced nylon material cage has the following characteristics: one is the new cage using engineering plastics -
—
PA66 glass fiber reinforced nylon material;
Second, the injection molding processing method, technology of cage is better, the size and shape of the stability;
Three is to use nylon material cage has certain self lubricating effect;
Four is based on the structure optimization design, can make the roller in the process of high speed oscillation amplitude decreases, and thus to a certain extent, reduce the noise.
Second, the spindle FAG import bearing the correct method of use: 1, in FAG bearing import bearing assembly hole size, shape, precision is not good, FAG import bearings will be affected by its can not play the best performance.
For example, if the mating part bearing inner hole size precision and shape accuracy is bad to cause FAG import bearing outer ring deformation, leads to the deterioration of the imported FAG bearing inner hole roundness;
If shoulder precision is not good, will produce FAG import bearing outer ring, roller tilt, intensifying concentrated load, the imported FAG bearing fatigue life down, more serious causes cage damaged, sintering;
If imported FAG bearing inner ring of the precision of the spindle rod imported FAG bearing retainer is bad, such as size, roundness, cylindricity, waviness and roughness, location, degree of accuracy, can also lead to a complete set of spindle vibration value increase significantly.
2, complete sets of imported FAG bearing carefully before assembling precision matching, so a user before use, the scattered FAG bearing import parts without measurement matching again, can't be used interchangeably.
3, about the spindle FAG import bearings and spindle foot cleaning problem.
Mould structure is compact, because bolsters bolsters, there are many other parts of their cleanliness may also affect work FAG import bearings inside the cavity of cleanliness.
Therefore, before the assembly parts adopt bolsters pre-cleaning, assembly assembly later, again to include imported FAG bearing assembly bolsters fine cleaning process is a reasonable method.
4, FAG import bearings should not be impacted by knock against and, when it is assembled knock against and impact of the collision between imported FAG bearing parts, bearing failure.
5, FAG import bearing edge should pay attention to control the edge Angle, strength and other factors, to avoid the edge caused by unreasonable FAG import deformation failure of bearing parts.
Phase 6, for more than rust or storage time longer FAG import bearings, rust or may arise because of rust-proof oil dry up and die roller sticky situation.
The correct maintenance of the three, FAG import bearings and maintenance methods: 1, first of all, the spindle spindle FAG import bearing during operation, to fully guarantee the lubrication, and according to the actual usage add lubricating oil regularly, not long time cutting oil.
So, for the user enterprise, should choose a better, more suitable spindle lubricating oil.
New special spindle oil can significantly improve the lubrication performance, extend the oil change period, prolong the service life of the import of spindle and FAG bearings, also has good anti-rust, anti-corrosion performance, etc.
2, second, adopting reinforced nylon material imported FAG bearing cage, using temperature should be lower than 120 ℃, it is strictly prohibited to cooking oil to clean.
3, in addition, the spindle maintenance should be paid attention to when cleaning method, to prevent damage or scratch the surface of the roller.
Try to remove the remains of the imported FAG bearing parts, flushing, suction bolsters internal clean should be adopted the method of residual oil is preferred.
Attention should be paid to avoid the dumping of type and make the clean garbage accumulation residue in bearing parts, lead to FAG bearing import produce the problem such as noise, wear failure.
