DZ series spindles are mainly used for chemical fiber blended yarns. The use of textile machinery spindles and cotton spinning enterprises is better to use and maintain. It is very important. The main product manufacturer's angle combined with the user's use to talk about the spindle bearing series products. Performance characteristics: liquid dynamic and static pressure bearings commonly used shaft shaft with shaft DZ series spindle bearings are mainly used for cotton, wool, hemp, enamel, chemical fiber, pure spinning and blending spinning machines and twisting machines and other supporting textile machinery spindles. For cotton spinning companies, how to better use, maintain and maintain these components is very important. Here, the author mainly discusses some methods and suggestions on the use, maintenance and maintenance of the spindle bearing series products from the perspective of the product manufacturer and the user's use.
1. As a special bearing for textile, the spindle bearing has a special structure. It adopts a single-row radial short cylindrical roller structure without inner ring and is a high-speed precision bearing that bears pure radial load. The assembled integral bearing is still open. Considering the assembly, packaging, transportation and user reassembly requirements, the current spindle bearings mainly use a special anti-rust oil. It not only has good anti-rust performance, but also ensures that the bearing is not prone to scatter when entering the final user assembly.
2. Due to the single-row radial short-circle roller, the series of bearings are rigid and bear large radial load; high manufacturing precision, flexible rotation, stable, low noise, suitable for high-speed operation; simple structure, low power consumption; maintenance More convenient
3. The current implementation standard of the spindle bearing series products is still: FZ/T92025-1994 "DZ series spindle bearing" textile industry standard
4. The cage with new reinforced nylon material has the following performance characteristics: First, the new cage adopts engineering plastics – PA66 glass fiber reinforced nylon material; second, it adopts injection molding processing method, and the cage has good processability and size. And the stability of the shape is also good; the third is that the cage with nylon material has a certain self-lubricating effect; the fourth is that by optimizing the design of the pocket structure, the swing amplitude of the roller during high-speed operation can be reduced, thereby Reduce noise to a certain extent.
