Main structural characteristics
1. Two-stage reduction transmission design
A well-designed two-stage reduction scheme is adopted, with the load distributed across the two-stage main reducer mechanism and the wheel rim, reducing component fatigue losses, adapting to the frequent start-stop, steering, and impact loads of a wheeled excavator, and effectively extending the overall service life of the drive axle.
2. Contour transmission cycloidal bevel gear main reduction
The main reducer is equipped with contour cycloidal bevel gears, which offer high strength, high transmission efficiency, low operating noise, stable meshing under variable loads, and consistent and stable output power.
3. NGW-type planetary wheel-side braking mechanism
The wheel section is equipped with a classic NGW planetary reduction transmission, with a compact and rational overall structure, achieving a large reduction ratio within a small installation space, simplifying the overall machine layout for equipment manufacturers.
4. Integrated ductile iron axle housing
The axle housing is made of high-quality ductile iron as a single casting, offering excellent overall rigidity and superior overload resistance. It can withstand the continuous heavy impacts of 16-20 ton wheel excavators without easily deforming or being damaged.
5. Closed wet multi-disc brake system
It is equipped with a fully sealed multi-disc wet braking system, hydraulic pressure and spring release, complete isolation from dirt, water, and dust erosion, constant braking torque under heavy and harsh operating conditions, stable braking performance, and a high safety factor.
Comprehensive enterprise strength
Shandong Lutong Heavy Industries Machinery Co., Ltd. is a professional manufacturer specializing in the research, development, and large-scale production of drive axles for construction machinery. The company provides a complete set of drive axle support solutions to the world's largest equipment manufacturers.
1. Fully automated professional production line
The company has built a series of integrated automated production lines for processing, assembling, and testing drive axles, covering the entire process of fine gear grinding, CNC milling of axle housings, automatic assembly of main shaft and wheel rim components, automatic lubrication, and leak testing. Automated production reduces manual handling errors, ensures consistent dimensional accuracy for each batch of axle housings, and enables large-scale continuous production to meet orders from equipment manufacturers worldwide.
2. Strict quality control throughout the entire process
Incoming raw material inspection:Ductile iron castings, alloy gear steels, and brake friction linings can be stored only after passing material metallographic inspection.；
Semi-finished product inspection:Full inspection and sampling of dimensions of CNC machined parts, individual hardness testing of gears and tooth profile accuracy.
Bench testing of finished products:self-built 150-ton multifunctional loading laboratory and long-term technical cooperation with Chongqing Zhongqi Research; each finished axle undergoes bench testing for load, durability, braking, and noise reduction before leaving the factory.
Final offline inspection of finished products:before packaging, the entire machine is fully checked for sealing, running tests, and the integrity of accessory appearance. All products can include complete test reports and bench test data for the main manufacturer, facilitating the recording and archiving of quality information for your company's entire equipment.
3. Stable and efficient delivery, delivery guarantee
Main series such as the WGL150 rigid bridge have sufficient reserves of raw materials and finished products, and standard models can be shipped in batches within 3–7 working days; orders for customized products are planned separately to shorten the trial production cycle and the delivery of sample batches.
The company has well-developed cooperation channels in domestic land transportation and export sea logistics. Goods can be shipped to Russia, Turkey, Brazil, India, and other countries around the world. It is equipped with a full range of services for anti-corrosion packaging, container packing, and customs clearance documentation. There is no risk of stock shortages for equipment manufacturers cooperating with them on a long-term basis.
