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:
- Steel
- Sugar
- Paper and pulp
