Ultra lapping refers to the good lubrication condition, the workpiece rotate at a certain speed, at the same time with fine grit stone at a certain pressure to the surface of workpiece processing, and in the direction perpendicular to the workpiece rotation for reciprocating movement of a processing method. It has the following features Buy Bearings Online http://www.bearing-sa.com/ :
1. Can effectively reduce the waviness. Ultra lapping process, when the millstone in contact with the workpiece circular arc is greater than or equal to the wavelength of the workpiece surface waviness, can guarantee the millstone always ACTS on the wave without contact with the troughs, so that the peak contact pressure is bigger, convex peak is removed, thereby reducing the waviness.
2. Improve the ball bearing raceway groove shape error. Ultra lapping can effectively improve the raceway groove shape error, generally can be improved by about 35%.
3. Can make be ultra lapping surface compressive stress is produced. Ultra lapping mainly produced in the process of cold plastic deformation, therefore after lapping processing workpiece surface residual compressive stress.
4. Reduce the surface roughness value.
5. Can increase the contact area on the surface of the ring work. Super after lapping, ring work surface contact bearing area by 15% ~ 40% after grinding, increased to 80% ~ 95%.
6. High production efficiency, low labor intensity, easy to realize automation.
DZ series is mainly used in chemical fiber blended yarn twisting spindle bearing used textile spindle cotton spinning enterprises better use maintenance is very important to the author main manufacturer Angle combined usage about spindle bearing series of products using maintenance methods suggested spindle bearing performance characteristics: liquid static pressure bearing shaft shell with shaft 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.
1, 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, but also can ensure the bearing in the final user when assembling part of scattered children is not easy to happen.
2, as a result of short single-row radial circular roller, 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 is more convenient.
3 standards, the spindle bearing series products are: FZ/T92025-1994 DZ series of spindle bearings, textile industry standards.
4, 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.
