What is a girth gear?
The girth gear is a large, ring-shaped gear with teeth that is mounted around the outer surface of the equipment (drum-shaped machine) that rotates during operation. Basically, the girth gear operates large rotating equipment such as kilns, dryers and mills in various industries like mining, cement, and power. At CPG, our quality engineers analyze the product at every phase of the manufacturing process to ensure that it meets international industrial standards. Our valuable clients appreciate our products as we offer superior design, dimensional accuracy, excellent strength and easy installation.
A quick material selection guide
The girth gear is an essential element of some circular industrial equipment, such as ball mills, rotary kilns, and rotary dryers. For Modern Industries, what plays a major role is selecting the correct material of equipment to ensure maximum output and maximum equipment efficiency for lower downtime.
We need to ensure load capacity (ability to bear operational load), operating conditions (resistance to temperature, humidity and corrosion), maintenance requirements (material should be easy to maintain and repair) and budget constraints (Material Cost and Expected Lifespan).
What Sets Our Girth Gear Manufacturing Apart?
- Girth gear manufacturing by double stress-relieving process
- Basic tooth profile as per DIN 3972 II
- Accuracy grade as per DIN 3968 "AA"
- We ensure quality through NDT – UT – MPI – DPT.
- Gear Tooth profile Inspection by Chordal Thickness measurement at various chordal addenda and base tangent lengths at various positions radially and axially
Why is proper alignment essential for the Girth Gear?
Proper alignment is crucial for the efficient operation of equipment because misalignment can result in loss of production and even equipment failure.
With the proper alignment process, measurements can be done using specialized equipment such as laser alignment tools and dial indicators. This equipment provides accuracy and helps to identify any misalignment issues.
