Spindles bearing maintenance and repair methods
 
 
DZ series spindles bearings are mainly used for cotton, wool, linen, silk, chemical fiber, spinning pure and blended spinning and twisting machine supporting the use of textile machinery spindles. For cotton spinning enterprises, how to better use, care and maintenance Well these special items is very important. In this, the author's point of view and from the manufacturer or with the user's usage, to talk about the use of products bearing spindles, maintenance and some methods and recommended maintenance aspects.

Performance and features bearing spindles

As textile spindles bearings bearing, its structures more special. It uses no inner ring single row radial short cylindrical roller structure, is to bear the pure radial load, high-speed precision bearings. Overall bearing assembly remains open after the state, taking into account the assembly, packaging, transportation and reassembly of user needs, the current main bearing spindles using a special anti-rust oil. It not only has good anti-corrosion properties, but also to ensure the bearing is not easy to occur when a user enters the final assembly part of the dice.

As a result of single row radial short round roller, so the series bearing rigidity, radial load large; manufacture of high precision, rotating flexible, stable, low noise, high speed adaptation; simple structure, low power consumption; maintenance more convenient .

The current implementation of the standard spindles bearing products remains: FZ / T92025-1994 "DZ series spindles bearings" textile industry standards.

Using new reinforced nylon material holder has the following characteristics: First, the new holder with plastic --PA66 glass fiber reinforced nylon material; the second is the use of injection molding processing methods, the process of holding cage is better, the size and shape Stability right; the third is made of nylon holder has a self-lubricating effect; Fourth, through the pore structure of the pocket to optimize the design, you can make the roller swings at high speed during operation is reduced, resulting in a certain reduce noise degree.

The proper use of the bearing spindles

First, in the bearing housing bearing fitting hole size, shape, and precision is not good, the bearings will be affected, you can not play the best performance. For example, if the inner part with the bearing hole dimensional accuracy and shape accuracy is not good cause bearing outer ring deformation, resulting in deterioration of bearing roundness; if precision is not good stop shoulder, will have bearing outer ring, roller tilt, intensified focus load bearing fatigue life drops, more serious cause holder breakage, sintering; if the precision spindle bearing inner ring gear rod bearing bad, such as size, roundness, cylindrical, waviness, roughness, location of accuracy, etc., will also contribute significantly to increase the value of the entire spindle vibration.
