Straight-toothed gear / flange / for industrial applications

Technical Details
With more than 1000 girth gears sold over the world FLSmidth MAAG Gear is a leading supplier in the cement and mineral industry.

Technical description

As member of AGMA (American Gear Manufacturers Association), we do actively take part in defining the standard for gear rating calculations and service factors (AGMA STD 6014).

We provide girth gears in three different designs

Fabricated steel
- forged ring
- rolled plate
Cast steel
Ductile (Nodular) cast iron

Fabricated gears became more common in the past and are constructed with forged steel gear rim materials and electro welded body structure. The rings are manufactured from a whole block of high resistance alloy steel. After the rough machining of the ring, we carry out hardening and tempering heat treatment in order to improve the mechanical characteristic and therefore its relevant performance.

Avantages of fabricated girth gears

The forged material structure excludes the risk of inclusions
Structure defects like gas holes, micro shrinkage, pin holes, hot tears, sand and slag inclusions are avoided
Hence, repair welding of the body structure and e.g. grinding of toothed areas is not required.
The fabricated manufacturing procedure excludes the need for patterns and risers
Rim material has higher hardness and higher strength than the material used for the underlying structure (i.e. web, gussets)

These features will reduce the lead time and costs. Fabricated manufacturing ensures a fast delivery. This is especially beneficial in an emergency situation, where the existing gear rim is suffering from damage.
