Cadia Girth Gear Failures

2014. 9. 22. A further conclusion from [2] is that the pinion diameter is more important that gear blank profile (Y or T). So, according to [2], the failure of those gears was caused by a design fault, i.e., the diameter of the pinions in the Cadia ball mills are too small. Figure 2: Model of gear contact in [2] similar to a spur gear, not a helical gear


Gear Failure Analysis Involving Grinding Burn : Gear

Tempering of the case-hardened surface, commonly known as grinding burn, occurs in the manufacturing process when control of the heat generation at the surface is lost. Keywords grinding burn, aerospace gears, failure, magnetic particle inspection, crack propagation, nital etch

Gear Failure Analysis Seminar

In AGMA’s Gear Failure Analysis Seminar, attendees will examine the various types of gear failure, such as macropitting, micropitting, scuffing, tooth wear and breakage. Possible causes of these failures will be presented, along with some suggested ways to avoid them.


Root cause analysis of bowl-mill pinion shaft failures

2013. 4. 1. After a detailed examination of the operating history, it was observed that at the time of the failure, hard, rock-like lumps were present in the inlet coal discharge and they were struck in the bull ring segment as they could not be crushed. One of the bowl mill roll also was damaged as
