Custom Forging herringbone gear shaft

Herringbone gear shaft (Double helical gear shaft) used in mining machinery, mainly for efficient transmission of large torque and high load, to ensure the stable operation of heavy equipment. The retracting groove is designed to facilitate machining and maintenance, reduce stress concentration and extend service life. Its special structure effectively responds to the harsh conditions and high strength needs in mining operations, improves transmission efficiency, reduces the failure rate, and ensures the reliability and safety of mining and transportation equipment, which is an indispensable key component of mining machinery.  

Production Process

Forging & Casting

Rough machining

It's easier and accuracy to control the inner termperature of furnace, so it can improve the purity of steel.It can control the quality of steel from the material. We can casting 1500-50000kgs /PCS.Forged support roller can improve their mechanical properties and extend their service life. This can help customers save costs and improve the working efficiency of the equipment

Rough machining is usually followed by finish machining.This part has completed the rough machining stage; the next steps are heat treatment and finish machining.

Heat treatment

Finish maching

Advantage of our heat treatment

a. Professional, specific furnace, single-minded

b. Well-type electric furnace,keep the temperature uniformity within ±1℃

c. Small deformation,little oxide layer,reduce material cost

d. Different materials can be cooled at the best speed

e. Large capacity, completed variety of quenching medium: oil,water,salt water,sythetic quenching medium

CNC Gantry Milling: The accuracy can arrive 0.01mm

Test

All our products will do Test, that's much difference than other factory.test can detect whether there are excessive defects inside the product, which can better ensure product quality.

Company Profile

Who We Are

Established in 2002, Luoyang Wangli Heavy Machinery Co.,ltd. focus on metal research and mining machinery spare parts. Our factory located in Luoyang, one of important base for heavy machinery in China. 2 factories over an area of 13,300 square meters, based on 100+ sets of equipment, our production capacity reaches 12000 Tons/Year. has passed ISO 9001 quality managment system certification in 2015.
Our mainly products: dragline excavator spare parts,rotary kiln spare parts, large modulus gear (gear shaft), gearbox ect. 40+ patents with over 45 years experience to help focus on improve the service life of spare parts. We belive that more than 80% reason of mechanical parts' working life depends on hot processing (steel making/forging/casting/welding/heat treatment). Eight material engineers will control the quality from the original resource.
 
Over the past 15+ export experience, we have served 200+ compaies in 50+ countries and regions, During these times, three international key projects, such as segment girth gear used in the Suez Canal in Egypt.
We believe that innovation is the key to success and attracts talents who can think differently. Together, we can make a real difference.
