Girth Gears

Girth gears are high precision components, which are preferred over the gear less drives because of their lower initial cost, uncomplicated installment procedure and smaller functional and maintenance costs.

 

One of the most important mill and kiln drive systems, girth gear and pinion are generally two of the highest cost components in the complete drive assembly. In addition, the girth gears are generally the biggest physically and, because of the various measures essential to protect the high precision finishes, are difficult to store for a longer period of time.

 

High precision components, the girth gears are known to deliver high efficiency and their overall life depends on proper lubrication and alignment. The capital cost of girth gears is lower than others and their installation is simple and takes less time when compared to others.

 

Over the years, girth gear materials have made various changes on their own. These gears can be made out of various types of materials, such as cast iron, carbon steel, alloy steel, hardened steel, bronze, and more. Casting is improved with the use of full ring risering techniques. Simulation programs are installed to ensure proper solidification. New materials are used with an added benefit of increase in hardness and hence increased ratings.

 

Applications
Because of the high efficiency, superior performance and long service life, girth gears are used in variety of industrial applications, including:
