BARTELL ROTARY BASKETS
Gregor A., Mrkos J.
pages 158 - 161, full text

The aim of this paper is to solve the problem with emerging and growing fatigue cracks in Bartell rotary baskets operated in NKT cables s.r.o. Carried out were several strength analyses, strain-gauge stress measurements, mechanical vibration measurements on the mounting frame of the basket rotor bearings, magnetic particle tests, modal and harmonic analyses. The benefits of design modifications were assessed. Suitability of the technology used. Teams of people across the Republic dealt with the device. The original baskets were manufactured by the Canadian-American company Bartell. The cracks appeared after 3 months of operation and gradually expanded to such an extent that the device was unable to operate. Subsequently, new baskets were manufactured according to the design of Pemavako s.r.o., that slightly improved the original baskets. Cracks were detected on these improved baskets after 8 months of operation, the device is still in use and the user wishes to extend its life as much as possible.
