DZ series of spindle bearing maintenance and maintenance method DZ series of spindle bearing is mainly used for cotton, wool, linen, silk, chemical fiber, pure yarn and blended spinning frame and twisting machine and other supporting the use of textile spindle.For cotton spinning enterprise, how to better use, maintenance, and maintenance of these thing that is important.In this, the author mainly from the Angle of the manufacturer and user's usage, discuss the use of spindle bearing series products, maintenance, and maintenance of some methods and Suggestions.The performance of the spindle bearing and some special bearings as textile spindle 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 bearings.After assembling the overall state of bearing is still open, 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, and can ensure bearing in at the same time Entered the final user when assembling part of scattered children is not easy to happen.With single-row radial roller short circle, so this series of bearing strong rigidity, 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 Maintenance is more convenient.

The spindle bearing series product standards are: FZ/T92025-1994 DZ series of spindle bearings, textile industry standards.Adopt the new reinforced nylon material cage has the following characteristics: one is the new cage - PA66 glass fiber reinforced nylon engineering plastics materials;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.Spindle bearings in the first place, the correct way of using the bearing pedestal bearing assembly hole size, shape, precision is not good, under the condition of bearing will be influenced by it, can't play the best performance.For example, if the mating part bearing inner hole size precision and shape accuracy is bad to can cause deformation of bearing outer ring, leads to the deterioration of the bearing inner hole roundness;If shoulder precision is not good, can produce bearing outer ring, roller tilt, intensifying concentrated load, the bearing fatigue life down, more serious causes cage damaged, sintering;If the bearing inner ring of the precision of the spindle blade 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.

Second, the complete bearing carefully before assembling precision matching, so a user before use, the scattered without measurement matching bearing parts, can't be used interchangeably.Third, the question about cleaning spindle bearing and bolsters.Mould structure is compact, because bolsters bolsters, there are many other parts of their cleanliness may also affect the purity of the bearing work within the cavity.Therefore, before the assembly parts adopt bolsters pre-cleaning, assembly assembly later, again to include bearing assembly bolsters fine cleaning process is a reasonable method.Fourth, the bearing should not be impacted by knock against and, when it is assembled knock against and collisions between the impact of the bearing parts, bearing failure.Fifth, when bearing edge should pay attention to control the edge Angle, strength, avoid the edge caused by unreasonable deformation failure of bearing parts.Sixth, exceed the antirust period or stored for a considerable time bearing, rust or may arise because of rust-proof oil dry up and die roller sticky situation.Bearing first of all, the correct way of preventive maintenance and the spindle of the spindle 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 spindle and bearing, also has good anti-rust, anti-corrosion performance, etc.Secondly, using reinforced nylon material cage bearing, using temperature should be lower than 120 ℃, it is strictly prohibited to cooking oil to clean.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 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 produce the problem such as noise, wear failure of the bearing.
