girth gears mechanical

Different mechanical wear of teeth creates different wear pattern on working components surface. Below some example: Heel and toe – this kind of pattern coming from the girth gear axial run-out. Higher wear will be observed on downhill part of teeth. The wear will be uneven.

The mechanical properties of ductile cast iron are very similar to those of cast steel, even at identical hardness values. Of the more than 700 ductile cast iron girth gears manufactured so far by Ferry Capitain, not a single one has failed due to tooth damage.

Gear tooth surface wear involves removal or displacement of material due to mechanical, chemical or electrical action. The three major types of wear are adhesion, abrasion and polishing. Adhesion is the transfer of material from the surface of one tooth to that of another due to welding and tearing (Figure 5).

As a principle structural and mechanical component, the girth gear on a rotary drum has widespread effects when allowed to wear. As a result, gear wear should be addressed immediately, typically through replacement, though in cases of onset wear, simple adjustments may prevent further damage.

In mechanical engineering, backlash, sometimes called lash or play, is a clearance or lost motion in a mechanism caused by gaps between the parts.It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence".

In a ring-gear (or girth gear) drive, the gear is bolted to the outside diameter of the mill shell, Figure 3. In one configuration, each low-speed motor (usually 200 rpm) supplies power to the ...

Girth Gears — More than Just Metal and Teeth Steve Lovell Introduction The clear majority of published knowl-edge about gear manufacturing relates to two main subjects; material quality and tooth accuracy. In most cases, the mechanical accuracy of the gear blank is taken for granted and, after all, pre-paring a gear blank normally consists of

The girth gear drives that are used in tube mills, coolers, washing drums, kilns, calciners and other machines have to transmit enor-mous torques‚ i.e. often up to 50,000 Nm. It is only natural that this kind of force subjects the gear wheels to very high stresses. Such gears are usually designed as spur or helical gears with
