Honeycomb structure bushing in a filament winding machine
Material
ZX-100K as replacement for bronze.
Description of the application
The here described bearing is used in filament winding machines for the paper industry. It supports the centre sleeve, that
transports the to be wrapped paper roll. The paper rolls have a diameter of 2m and the shaft has a length of 3m. The bearing was up-to-now made of bronze.
Problem
With the lubricated bronze bearing the precision was a problem also with a solid lubricant. A material that allows a higher precision was needed. Furthermore, a low break loose torque is required.
Problem-solving
Here a plain bearing bush made of ZX-100K with a honeycomb structure, needed to reduce the static and kinetic friction, has been
used. The bushing is manufacture with a tolerance of 2-3 hundredths of a millimetre, with an outer diameter of 185mm, an inner
diameter of 165mm and a length of 80mm. The groove depth is 1mm, the groove width 3mm. The bearing clearance is 0,05mm
Working life
The bushings is been successfully used since 1992.
Advantages
70% price reduction , improved precision, dry running, no high break loose torque.
