With more than 1000 girth gears offered in excess of the globe CZPT Equipment is a leading provider in the cement and mineral industry. And as member of AGMA (American Equipment Producers Affiliation), we do actively get portion in defining the regular for equipment ranking calculations and services factors. 

We provide girth gears in 3 different styles

Fabricated steel
– solid ring
– rolled plate

Solid steel 

Ductile (Nodular) cast iron  

Fabricated gears became a lot more common in the past and are built with cast steel gear rim components and electro welded body composition. The rings are manufactured from a complete block of substantial resistance alloy steel. Soon after the rough machining of the ring, we carry out hardening and tempering warmth treatment method in purchase to increase the mechanical characteristic and therefore its appropriate efficiency.  

Avantages of fabricated girth gears

The cast material structure excludes the risk of inclusions

Structure defects like fuel holes, CZPT shrinkage, pin holes, scorching tears, sand and slag inclusions are prevented

Hence, restore welding of the entire body construction and e.g. grinding of toothed regions is not necessary.

The fabricated producing method excludes the need to have for styles and risers

Rim content has higher hardness and larger power than the substance employed for the underlying composition (i.e. net, gussets)

These functions will reduce the direct time and expenses. Fabricated production ensures a quickly supply.

This is specifically advantageous in an unexpected emergency situation, exactly where the existing gear rim is struggling from damage

The advised supplies for the worm are hardened steel and bronze for the worm gear. Nonetheless, dependent on the software, unhardened metal worms can run sufficiently and far more economically on solid iron worm gears rated at fifty%. In addition to steel and hardened metal, worms are accessible in stainless steel, aluminum, bronze, and nylon worm gears are offered in metal, hardened metal, stainless steel, aluminum, nylon, and non-metallic (phenolic).
The equipment ratio of the worm equipment established is established by dividing the number of enamel of the gear by the variety of threads. Consequently, solitary thread yields greater ratios than multithreading. All ep worm equipment bushings have remaining or appropriate thread. ep worm gear sets are accessible in single, double, triple and quadruple threads.
