case study cement mill girth gear

The cement mill is driven at 16 rev min"1 by a girth gear fitted to the head wall. The girth gear is driven by two pinions, each being connected via a gear box and coupling to a 1560 kW electric motor. The speed ratio between the pinions and the girth gear is 7:1. The girth gear mounting on the mill shell is shown in Fig. 1.

Abstract This paper describes the fatigue failure of girth gear manufactured from low alloy cast steel of rotary dryer in a chemical plant. The cracks of T-section web of the girth gear occurred at the end of 25 year working period because of stress intensity factor. Because of normal condition of working surfaces of teeth, spare gear was not thought and repair welding …

Spur gears with helicoid teeth are called Helical Gears. The majority of calculations for spur gears can be applied to helical gears too. This type of gear comes with two kinds of tooth profiles in accordance with the datum surface. (Figure 2.9) Fig. 2.9 Right-handed Helical Gear (Important Gear Terminology and Gear Nomenclature in Fig 2.9 ...
