STRESS CONDITIONS IN IMPROVED CUTTER TEETH DESIGNED FOR THE BUCKET WHEELS OF EXCAVATORS WORKING IN OPEN PITS

Alin Daniel RADU, Gheorghe-Bogdan URDEA

Abstract


This paper presents the results of research on the design of a range of standard-sized teeth with improved characteristics for excavators working in coal mines, based on the specific cutting resistance of coal and rock in open pits. The results are based on experimental tests conducted in laboratory conditions involving the cutting of coal and rock samples taken from representative mining fields of S.N.L. Oltenia.
