Analysis of the drive shaft fracture of the bucket wheel

Abstract Drive in most bucket wheel excavators (BWEs) is accomplished through its electric motor, cardan shaft and planetary gearbox. In the BWE SchRs630/6x25, the planetary gearbox is cantilevered at the end of the hollow shaft which transmits the torque through the sprocket to the caterpillar track chain. In this BWE, the drive shaft fracture occurs at the point of support on the penetration ...

Failure analysis of conveyor pulley shaft ScienceDirect

Apr 01, 2013 The finite element stress analysis concluded that stress levels developed in the shaft at the failure location are too low to lead to fatigue failure when considered in isolation. Tests performed on samples of the shaft showed that the material has a fatigue limit at a stress range in excess of 300 MPa.

Applied Failure Analysis Level 3 Finning Cat

Applied Failure Analysis Level Two begins with a review of the basic principles of Applied Failure Analysis Level One. The failure analysis process itself will be applied to gears, anti-friction bearings, threaded fasteners, and hydraulic pumps and motors. Using this process, you will arrive at the most probable root cause of failure of a selection of components relevant to this course.

Root causes of noise artifacts in ultrasound images

Root Cause: Behind a wall, in the area where the scans were performed, was an elevator shaft. Every time the elevator passed-by and a scan was taking place, noise appeared in the middle of the image. The issue only occurred when using a TEE probe. Solution: The elevator motor was replaced, and the problem resolved.
