The pinion at the mill's girth gear can be connected via a double-jointed coupling with spacer to ensure the adjustability of the pinion. Single pinion drives are supplied in both fixed and self-aligning design. MDSS offer flexibility and precision for the optimum tooth mesh.

Read OnA tube failure is usually a symptom of other problems. To fully understand the cause of the failure, you must investigate all aspects of boiler operation leading to the failure in addition to evaluating the failure itself. When you experience tube failures, take advantage of B&W's expertise to help you determine and eliminate the root cause ...

Read OnThe present case failure had not complete fracture of the gear teeth a deflection occurred at the pinion gear which resulted from the applied stress producing a deflection shape of teeth as shown ...
Read OnMill Drive Shaft Failure A chemical company provided two sections of a drive shaft to determine the cause of a fracture that developed in the tapered, keyway area. The failure consisted of a transverse fracture through the shaft diameter near the keyway center, coupled with a peeling failure in the keyway that progressed around and along the shaft.
Read Onpremature failure of the key components such as gears and could be very costly. KEYWORDS: Failure analysis, Key, Keyway crack, Herringbone gear failure, 2-Hi pinion gearbox. 1. Introduction . Herringbone gears are key components of gearboxes which transmit power under heavy loads. Such gearboxes are extensively used in steel industry.
Read Onadds a fifth roll at the bottom of the tube, allowing smaller diameter side rolls to be used. Many smaller mills use three rolls mounted 120 degrees apart. Some are orientated with a grooved roll at the top of the tube (D), others with a roll directly below the tube. D eliminates edge misalign-ment and is especially suited to D/T ratios above 10:1.
Read OnThe fatigue in the gears induces the formation of cracks in the root of the gear tooth which propagates with each rotational cycle of the gear and ultimately leads to the failure of the gear tooth. Pitting: This is a major cause of …
Read OnThe number of cycles accumulated by the pinion at the time of failure was lower than 3 X 108. This, therefore, was certainly not a low cycle failure, but it was only one-third of the total design life. The failed pinion was replaced and the mill restarted. During a …

Annulus Gear.
Read OnSurface fatigue is the failure of a material as a result of repeated surface or sub-surface stresses beyond the endurance limit of the material. Figure 2.1 indicates the theoretical mutual Hertzian stresses occurring when a gear and pinion mesh. There are compressive stresses at the surface and unidirectional and bi-directional sub-surface ...
