Kiln Girth Gear is the main component of rotary kiln and ball mill, and needs to drive the entire cylinder to run for a long time.
Kiln Girth Gear is one of the key components in the rotary kiln transmission. Its installation quality directly affects the stability of the rotary kiln transmission system, the stability of the rotary kiln operation, the service life of the kiln lining and the operation rate of the rotary kiln.
Main material: ZG45, ZG42CrMO
Applicable Industries: cement, electric power, metallurgy, chemical industry, non-metallic minerals and other industries
The big gear, also known as the big ring gear, is the key component of the rotary kiln, ball mill and other equipment. Among them, the large ring gear of the rotary kiln is one of the key components in the rotary kiln transmission. Its installation quality directly affects the stability of the rotary kiln transmission system, the stability of the rotary kiln operation, the service life of the kiln lining and the operation rate of the rotary kiln. .
Due to the needs of manufacturing capacity, transportation and installation, the large ring gear is composed of two half-gears, which are connected together with opposite screws, and are tangentially fixed on the kiln body through a spring plate. In order to complete the installation and alignment of the large ring gear with high quality, a scientific and feasible construction plan must be formulated whether it is a new installation or a reset installation after an overhaul.
According to customer requirements, select the appropriate wooden mold for modeling design, use Huazhu CAE to simulate pouring before pouring, strictly follow the wooden mold – modeling – smelting and pouring – heat preservation – pit cleaning – heat treatment – roughing and finishing – packaging and delivery The technological process of casting high-quality ring gear castings.
1. Unique heat treatment technology improves wear resistance
The large ring gear adopts a unique heat treatment technology in the casting, which optimizes the ring gear structure, improves the hardness, and greatly enhances the wear resistance and impact resistance of the product.
2. High-strength steel ensures service life
High-strength steel is used for ring gear casting, and the transmission characteristics of the rotary kiln and ball mill are optimized to ensure the stability of the components under long-term operation and prolong the service life of the components.
3. Mass production is more efficient
With strong production strength of steel castings, it can produce large-scale production of large ring gears and other components, with short casting cycle and large output.
