Abstract

This paper presents results of theoretical and experimental analyses of loads, parent material, welded joints, manufacturing technology, design solution, and fracture surface of supporting structure of satellite planetary gear used in driving the wheel of bucket excavator type SRs 1300.26/5.0 +VR±10). Research was aimed to establish the cause of fracture of satellite support, followed by catastrophic failure of gear box and working wheel.

Keywords: bucket wheel excavator, satellites support, external load, welded joints
