And as member of AGMA (American Gear Manufacturers Association), we do actively take part in defining the standard for gear rating calculations and service factors. We provide girth gears in three different designsFabricated steel- forged ring- rolled plateCast 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 gearsThe forged material structure excludes the risk of inclusionsStructure defects like gas holes, micro shrinkage, pin holes, hot tears, sand and slag inclusions are avoidedHence, 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 risersRim 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 FeaturesExternal teeth Maximum diameter: 16000 mm Toothed face width: 1700 mm Maximum module: 45 by hob Maximum module: 65 gear finishing cutterInternal teeth Maximum Diameter: 6500 mm Maximum module: 25.4 Toothed face width: 400 mmForging material process Forging Final rolling Furnace cooling Control on production Water quenching Hardness testing Rough machining Ultrasonic testing and dimensional inspection Final inspection certificationApplications Our girth gears are applied in the cement and minerals industries: Various types of horizontal mills Rotary dryers Rotary kilns Any other large gear ring applicationPinionsZTIC Gear invested in significant resources and achieved many innovations with pinions. The right combination of material, hardness and finishing between pinion and gear is crucial for a long lifetime of the installed equipment. We design and manufacture pinions to match every customers need, no matter how unique the situation might be.
