Internal and external gear ring

Category:

Description

Internal Ring Gears provide a compact parallel shaft transmission drive with a large speed reduction. Used with a standard spur pinion the ratio is the same as that of two external gears, but the center distance is much smaller. The girth gear ring is the main component of rotary kiln and ball grinding mill which is required to be operated in a long time. These gears are one of the highest cost components in the entire drive assembly. The girth gears have a very big diameter and high precision finish. The girth gears have high efficiency and their overall life depends upon the proper lubrication and alignment.

Features and advantages

1) Material and precision could be a customer’s requirements. We can design as per working conditions and produce according to customer drawings.

2) The high strength steel was used in manufacturing the big gear rings. We also take the optimization for the product against the operation characteristics of the rotary kiln to ensure the stability of the component during the long time operation and extend the service life of the component.

3) Agknx Group has rich production capability in steel castings. For the components such as the girth gear ring, we can provide them in large production quantity with short cast period and large amount.
