What are forged shafts?

Forged shafts are cylindrical objects that pass through the middle of forged bearings, wheels, or gears, but there are also a few square-shaped parts. A forged shaft is a mechanical component that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. Generally, it is shaped like a circular metal rod, and each segment can have different diameters. The rotating parts in the machine are mounted on forged shafts.

The function of forged shafts

Forged shaft is one of the important components that make up a machine, and its main function is to support transmission parts for rotary motion (such as gears, worm gears, etc.), and transmit motion and power.

Classification of forged shafts

1. Classification by load condition

According to the different load conditions of forged shafts, they can be divided into three types: rotary forged shafts, transmission forged shafts, and center forged shafts.

• Rotary forged shaft: a forged shaft that is subjected to both bending moment and torque;

• Transmission forged shaft: a forged shaft that is mainly subjected to torque and not subjected to bending moments or very small bending moments;

• Forged shaft: a forged shaft that is only subjected to bending moments without torque;

• Whether the forged shaft rotates during operation, the center forged shaft can be divided into a rotating center forged shaft and a fixed center forged shaft.

• Rotating center forged shaft: When working, the forged shaft bears a bending moment and rotates;

• Fixed center forged shaft: When working, the forged shaft bears a bending moment and is fixed.

2. Classification by forged axis shape

According to the different shapes of forged shafts, they can be divided into curved forged shafts, straight forged shafts, and steel wire soft forged shafts.

• Curved forged shaft: Each forged shaft segment’s axes are not in the same straight line and are mainly used in machinery with reciprocating motion, such as curved forged shafts in internal combustion engines.

• Direct forging shaft: The forging axis of each forging shaft section is the same straight line. Direct forged shafts can be divided into:

• Step forged shaft: Its characteristics are opposite to those of a plain forged shaft, commonly used for the rotary forged shaft.

• Steel wire soft forging shaft: It comprises multiple sets of steel wires wound in layers and has good flexibility, which can flexibly transmit rotary motion to non-open space positions.

There are many types of materials for the shaft, and the following factors should be mainly considered when selecting:

• 1. Requirements for strength, stiffness, and wear resistance of the shaft;

• 2. Requirements for the heat treatment method and machining process of the shaft;

• 3. The material source and economy of the shaft.

The commonly used materials for shafts are carbon steel and alloy steel.

Carbon steel is cheaper than alloy steel and has lower sensitivity to stress concentration. It can improve its all-around performance through heat treatment and has good processing technology, making it the most widely used. For general-purpose shafts, medium carbon steel with a carbon content of 0.25-0.5% is commonly used. Especially for 45 # steel, ordinary carbon steel such as Q235A can also be used for unimportant or less stressed shafts.

Alloy steel has better mechanical and quenching properties than carbon steel but is more expensive and sensitive to stress concentration. It is often used for shafts with special strength and wear resistance requirements. Low carbon alloy steels such as 20Cr and 20CrMnTi can improve their wear resistance after carburization treatment; Alloy steels such as 20CrMoV and 38CrMoAl have excellent high-temperature mechanical properties and are commonly used for shafts operating under high temperature, high speed, and heavy load conditions.

It is worth noting that due to the small difference in elastic modulus between alloy steel and carbon steel at room temperature, it is difficult to improve the stiffness of the shaft by selecting alloy steel when other conditions are the same.

Low-carbon steel and alloy steel can improve their wear resistance through carburization and quenching and are commonly used for shafts with high toughness requirements or rotational speeds.

Ductile iron and high-strength cast iron, due to their excellent processability, no need for forging equipment, good vibration absorption, and low sensitivity to stress concentration, have been widely used in the manufacturing of structurally complex crankshafts in recent years. It’s just that the casting quality could be better controlled.

The blank of the shaft is often made of rolled round steel or forged steel. The internal structure of forged steel is uniform, and the strength is good. Therefore, important large-sized shafts are commonly used with forged blanks. The mechanical properties of commonly used materials for shafts are shown in the table.

Dimensions of Forged Shafts

Forged shafts come in various dimensions and specifications to accommodate diverse applications. Some critical dimensions and specifications include:

• Diameter: Depending on the application and material, forged shaft diameters can range from a few millimeters to several meters. Larger diameters are typically used for heavy-duty applications, while smaller diameters are more suitable for lightweight or precision applications.

• Length: Shaft lengths vary significantly, with some applications requiring short shafts of a few centimeters and others needing long shafts spanning several meters.

• Tolerance: The dimensional tolerance of a forged shaft is crucial in ensuring proper fit and function within an assembly. Industry standards or customer requirements typically specify tolerances.

• Surface Finish: The surface finish of a forged shaft impacts its friction, wear, and corrosion resistance. A high-quality surface finish is essential for optimum performance in many applications.

The Forging Process of forged shafts

The delivery size of hydraulic turbine shaft forgings ordered by a plant is Ø2580mm (Ø900mm bore) × 9342mm, and its rough machining size is Ø2650mm (Ø720mm bore) × 9935mm, weighing about 149t. The dimensions of the hydraulic turbine shaft forgings blanks are shown in Figure 1.

Figure.1 Hydraulic turbine shaft forging blank

Technical requirements

According to the standard requirements provided by the user, the chemical composition, hardness, and mechanical properties of the forgings are shown in Table 1, and the overall toughness of the forgings is high.

Manufacturing process

Steelmaking process

According to the manufacturing outline, the process of VD+VT is adopted for steelmaking, and the ingot weight is 272t. The specific process flow is as follows: rugged steel from electric furnace → LF refining furnace → heating → alloying → vacuum (VD) in refining furnace → fine adjustment of composition → vacuum pouring (VT) → hot delivery.
Test the chemical composition of the steel; see Table 2.

Forging process

Hydraulic turbine shaft forging weight 148.89t, an ingot utilization rate of 54.7%. The forging process is completed in four fires; after the ingot body is discharged, the pier is roughened with a spherical pier plate with holes, and the mandrel is drawn long after punching. Due to the limitation of the existing mandrel length, the length is drawn in stages. First, the notch at the water outlet end is drawn, the notch at the riser end is drawn, and the finished product is finished.
Table.2 Chemical composition of ingot for hydraulic turbine shaft (mass fraction, %)

Actual composition	C	Si	Mn	Cr	Ni	Mo	V	Ceq
	0.29	0.32	1.28	0.2	0.19	0.1	0.04	0.584

The flange end of the forging has an outer diameter of Ø2650mm and a bore size of Ø720mm. For this kind of small bore and large diameter shaft parts, the phenomenon of the concave center will generally occur during forging and forming; secondly, the flange end occupies too much billet, which will easily lead to the problem of insufficient total forging length; in addition, the bore length of the forging blank is 9935mm, while the maximum mandrel length of our plant is only 8000mm. Therefore, the forging of the turbine shaft could not be completed with the existing auxiliary tools.
To solve the above production technical problems, avoid increasing the input of additional tools, and thus reduce the product manufacturing cost, we successfully realized the overall forging of a large hydraulic turbine main shaft through process innovation and auxiliary tool transformation. The main transformation methods include.

• (1) Using the spherical upsetting plate upsetting method and large anvil width ratio drawing length, which can effectively relieve the concave center of punching and solve the problem of end occupying material.
• (2) The design of the mandrel drainage extension pipe and the modification of the mandrel cooling system can solve the problem of drainage of extra-long mandrels.
• (3) Using the existing mandrel auxiliary tool, we designed the inverted drawing forging method by using the tail end (water mouth end) first and then the front end (riser end) to realize the overall forging of the extra-long hollow turbine main shaft.

Heat treatment process

To adjust and improve the forgings in the forging process formed during the overheating and coarse uneven organization, reduce the forging internal chemical composition and metallographic organization of the unevenness, refine the austenite grain of the material, improve the ultrasonic testing performance of the forgings, eliminate the grass-like wave, and finally make the forgings to achieve the mechanical properties required by the accepted standards, the post-forging heat treatment using “two normalizing + tempering “way. The heat treatment process curve after forging is shown in Figure 2.

Figure.2 Hydraulic turbine shaft forging heat treatment process curve

Analysis of results

When rough machining, the water and riser ends of the turbine shaft are sampled, respectively, and each end is symmetrically 180° to take tangential and axial samples for mechanical property inspection. The water and riser sampling positions are 90° from each other. Sampling test results are shown in Table 3.
Table.3 Hydraulic turbine shaft performance test results

Sampling Location		Rm/MPa	Rp0.2/MPa	A/%	Z/%	0 °C/KV	HBW
Water inlet	0 ° tangential	631	373	31	61.5	51、40、41	191
	180 ° axial	629	369	26.5	58	63、58、45	188
Riser	90 ° tangential	612	360	30.5	63	69、71、48，	195
	270 ° axial	615	364	31.5	59.5	63、63、51	189

The test results of “one pulling and three punchings” in four sampling positions show that the performance indexes of the hydraulic turbine shaft meet the requirements of users well, and the overall strength and toughness of the forgings reach a high level.

Machining methods for forged shafts

Processing Method and Precision of Outer Circular Surface

The shaft, sleeve, and disc parts have cylindrical surfaces. The commonly used mechanical processing methods for cylindrical surfaces include turning, grinding, and finishing. Turning is the most economical and effective machining method for cylindrical surfaces, but in terms of its economic accuracy, it is generally suitable as a rough and semi-precision machining method for cylindrical surfaces; Grinding is the main finishing method for cylindrical surfaces, especially suitable for precision machining of various high hardness and quenched parts; Finishing machining is an ultra-precision machining method (such as rolling, polishing, grinding, etc.) performed after precision machining, suitable for certain parts with high precision and surface quality requirements. Due to the varying economic processing accuracy, surface roughness, productivity, and production costs that various processing methods can achieve, it is necessary to choose reasonable processing methods based on specific circumstances to produce qualified parts that meet the requirements on the part drawings.

Turning of Outer Circular Surface

(1) The main processing method for the outer surface of shaft parts in the form of cylindrical turning is turning. The main processing forms include:

Rough turning

The rough parts of free forging and large castings have a large machining allowance. To reduce the shape error and position deviation of the outer circle of the rough parts and ensure even machining allowance in subsequent processes, the outer circle machining mainly involves removing the oxide skin on the excluded surface. Generally, the cutting allowance is 1-3mm on one side.

Rough turning

Small and medium-sized forging and casting blanks are generally directly roughened. Rough cutting mainly removes most of the surplus of the blank (usually with a stepped contour). When the stiffness of the processing system allows, a larger cutting amount should be selected to improve production efficiency.

Semi precision turning

Generally used as the final processing step for medium precision surfaces, it can also be used as a pre-processing step for grinding and other processing steps. For high-precision blanks, they can be semi-precision turned without rough turning. The final machining process for precision turning of the outer circular surface and the pre-processing before finishing.

Fine-tuning

The final machining process for high-precision and fine roughness surfaces. Suitable for machining the outer surface of non-ferrous metal parts, but since non-ferrous metals are not suitable for grinding, precision turning can be used instead of grinding. However, precision cars require machine tools with high accuracy, good rigidity, stable transmission, the ability to feed in small amounts, and no crawling phenomenon. Diamond or hard alloy cutting tools are used in turning, with a larger tool main deviation angle (45 ° -90 °) and a tooltip arc radius less than 0.1-1.0mm.

(2) Application of Turning Methods

1) Ordinary turning is suitable for various batches of shaft parts for cylindrical machining and is widely used. Bedroom lathes are often used to complete turning processing for single small batches; For batch and mass production, automatic and semi-automatic lathes and specialized lathes are used to complete turning to process.

2) CNC turning suits single-piece small, batch, and medium-batch production. The application is becoming increasingly common, with its main advantages being good flexibility and short equipment adjustment and preparation time when replacing processing parts; During processing, there is less extra time, and efficiency can be improved by optimizing cutting parameters and adaptive control; Good processing quality, few specialized fixtures, and low production preparation costs; The technical requirements for machine tool operation are low, and are not affected by factors such as the skills, vision, spirit, and physical strength of the operators. CNC turning is suitable for shaft parts for those with the following characteristics. Parts with complex structures or shapes have great difficulty in ordinary machining operations, long working hours, and low machining efficiency. Parts with high requirements for machining accuracy consistency. Due to their shape characteristics, parts with variable cutting conditions, such as those that require cutting grooves, turning holes, turning threads, etc., require multiple changes in cutting parameters during processing. The batch size is small, but each batch of parts is variable and has a certain degree of complexity. They can also be processed for shaft-type parts with keyways, radial holes (including screw holes), and distributed holes on the end face (including screw holes), such as shafts with flanges, keyways, or square heads on turning centers. In addition to regular CNC turning, various grooves and holes (including screw holes) on the parts can be processed on the surface, and other processed surfaces can be processed together. The highly concentrated processes result in higher machining efficiency and more stable and reliable machining accuracy compared to ordinary CNC turning.

3) Grinding of Outer Circular Surface

The method of using a grinding tool to process the surface of a workpiece at a high linear speed is called grinding. Grinding machining is a high-speed cutting method with multiple cutting tools and edges used for the precision machining of parts and hard surfaces. The range of grinding processes is very wide and can be divided into coarse, fine, and mirror grinding. The grinding tools (or abrasives) used in grinding processing have the characteristics of small particles, high hardness, and good heat resistance so that they can process harder metal and non-metallic materials, such as hardened steel, hard alloy cutting tools, ceramics, etc.; During the machining process, there are many particles participating in the cutting motion simultaneously, which can cut extremely thin and fine chips, resulting in high machining accuracy and low surface roughness values. As a precision machining method, grinding has been widely used in production. Due to the development of powerful grinding, the blank can be directly ground to the required size and accuracy, resulting in higher productivity.
