What is stepped shaft forgings? From the shape point of view, it is a forging that is divided into a shaft head, a shaft journal, a shaft body, a shaft shoulder and a shaft ring in a stepped shape. The stepped shaft is widely used in the transmission system, and its main function is to locate the installed parts. Its machining allowance is small, which reduces the waste of materials and saves costs. It has the characteristics of good stability and long service life.
This article will introduce the advantages, application, manufacturing process, supply size and other information of the stepped shaft in detail.
Designing the shaft as a stepped shaft has more advantages than a flat ordinary shaft. The design is stepped, which not only saves materials and reduces costs, but also has the advantage of high torsional rigidity. Because the shaft is subjected to high torque during transmission or gear shifting, to overcome this problem, the shaft is made stepped so that most of the torque can be specifically transferred to a specific step. And it can be made into a stepped shape so that the parts can be assembled to the required positions one by one.
1. Fast positioning of installation parts
2. High precision, high strength
3. Good anti-vibration ability
4. Multi-stage structure, multiple functions
5. Strong carrying capacity
6. Simple manufacturing process and low maintenance cost
7. Wide range of applications
Stepped shafts are usually used for assembly, disassembly and fixing of parts, and are also used in various mechanical transmission systems and industrial equipment, such as automation equipment, machine tools, electronic equipment, printing machinery, etc. It is also used in the positioning of lifting machinery components in overhead cranes and in braking mechanisms for handling train traction in railway systems.
(1) Material preparation and cutting
According to the product size and material requirements in the designed drawings, select high-quality bar steel.
(2) Stepped shaft forging
The number of sections of the stepped shaft is composed of multiple trapezoidal blocks, and the bar is forged into the first shaft section, the second shaft section, the third shaft section, the fourth shaft section and the fifth shaft section.
(3) Stepped shaft Heat treatment
In order to improve the strength and hardness of the shaft, it is necessary to heat-treat the forged shaft. By controlling parameters such as heating temperature and cooling rate, the structure of the material can be improved to achieve ideal mechanical properties.
(4) End faces and through holes
Process the end face first, ensure the size of the end face, and then process the through hole. The through hole processing is for the convenience of installation and connection.
(5) Processing
Rough turning – quenching and tempering – semi-finishing turning – finishing turning – end face turning – keyway milling – quenching – grinding outer circle – polishing, etc.
(6) Inspection
Strict inspection is required after the stepped shaft is completed, including appearance quality, dimensional accuracy, performance, etc.
Stepped Shaft Material
(1) stainless steel
(2) alloy steel
(3) carbon steel
(4) aluminum
(5) Copper
(6) Tool steel
(7) Nickel alloy
Stepped Shaft Size Range
The maximum diameter can reach 1200mm;
The longest length can reach 16000mm;
The size range of stepped shaft forgings may vary according to different applications and national standards. The specific size range should be confirmed according to the specific application requirements. Specifications can be customized.
Stepped Shaft Weight
Up to 80000 lbs (36 tons)
