US4360981A - Lip and tooth combination for bucket wheel
Removable bucket wheel teeth are provided with a rectangular-in-cross section shank portion and forwardly sloped shoulder areas for insertion into a complementarily-configured socket in a bucket lip. The resulting assembly is much more rigid and wears better than prior art tooth and lip configurations and tends to fracture preferentially when overstressed.

Examination of the causes of a bucket wheel fracture in a
Sep 01, 2010 · A bucket wheel excavator failure occurred in a brown-coal mine. The failure was caused by a fractured shaft of the bucket wheel. An attempt to determine the causes of the bucket wheel shaft fracture has been made. To that end, the character of changing loads and their maximum amplitudes has been determined by performing measurements on the excavator.
