Very interesting (maybe not to the customer) shaft failure. This is from a pinion gear shaft on a ball mill. They replaced the original coupling with a "custom" pin-and-bushing coupling that someone at a local machine shop "designed" and built. It's extremely large (almost 1000 lbs, each half) and the shaft only extended a little over halfway into the hub. It also had a tapered bore (they're ...

Sep 22, 2014 · 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

Ball mill pinion gear is mainly widely used in ball mill equipment, and their function is to transmit motion and power according to the specified speed ratio.The Ball mill pinion gear has a higher wear rating. Because the big gear turns one week, the Ball mill pinion gear needs to turn a few times, and Ball mill pinion gear we arness is several times that of the big gear.

The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about ...
