How Is a Girth Gear Inspected Before Delivery?

Short Answer:

A proper girth gear inspection helps identify defects, check machining accuracy and ensure reliable operation. For rotary kilns and ball mills, dimensional checks, surface testing and internal defect detection are essential before delivery.

Key Steps in Girth Gear Inspection

1.Dimensional and Tooth Accuracy

Check the gear diameter, tooth profile, module, pitch and mounting dimensions. Accurate machining helps ensure proper meshing with the pinion and reduces vibration and uneven wear during operation.

2.Surface and Internal Testing

Visual inspection and magnetic particle testing (MT) help identify surface cracks. Ultrasonic testing (UT) checks for internal defects such as shrinkage and porosity, especially in large cast steel sections.

3.Material and Final Quality Control

Material composition, mechanical properties and heat treatment results should meet the technical requirements. Final inspection also confirms that machining and assembly dimensions meet the customer's drawings.
