Stepped shaft is a shaft with multiple cylinders with different diameters connected together like steps. The turning of a stepped shaft is actually a combination of outer circle and plane turning. Therefore, the dimensional accuracy and steps of the outer circle must be taken into account when turning. Length requirements..
The spline shaft has a longitudinal keyway on the outer surface of the shaft, and the rotating part sleeved on the shaft also has a corresponding keyway, which can keep synchronous rotation with the shaft. While rotating, some can also slide longitudinally on the shaft, such as gearbox shift gears.

Prototype Case Studies
What is shaft
Shaft is a cylindrical object that passes through the middle of the bearing, the middle of the wheel, or the middle of the gear, but a small part of it is square. A shaft is a mechanical part that supports a rotating part and rotates with it to transmit motion, torque or bending moment. It is generally in the shape of a metal round rod, and each section can have different diameters. The rotating parts of the machine are mounted on the shaft.
Common shafts can be divided into crankshafts, straight shafts, flexible shafts, solid shafts, hollow shafts, rigid shafts, and flexible shafts (soft shafts) according to their structural shapes. The straight shaft can be divided into:
- ① The rotating shaft, which bears both bending moment and torque during work, is the most common shaft in machinery, such as the shaft in various reducers.
- ②Mandrels are used to support rotating parts that only bear bending moments without transmitting torque. Some mandrels rotate, such as the axles of railway vehicles, and some mandrels do not rotate, such as those supporting pulleys.
- ③The drive shaft is mainly used to transmit torque without bearing the bending moment, such as the long optical shaft in the moving mechanism of the crane, the drive shaft of the automobile, etc. The material of the shaft is mainly carbon steel or alloy steel, but also nodular cast iron or alloy cast iron. The working capacity of the shaft generally depends on the strength and rigidity, and also depends on the vibration stability when the speed is high.
Couplings belong to the category of general mechanical parts and are used to connect two shafts (active shaft and driven shaft) in different mechanisms to make them rotate together to transmit torque. In high-speed and heavy-load power transmission, some couplings also have the function of buffering, damping and improving the dynamic performance of the shafting. The coupling is composed of two halves, which are respectively connected with the driving shaft and the driven shaft. Generally, power machines are mostly connected with working machines by means of couplings, which are the most commonly used coupling parts for shaft transmission of mechanical products. In the late 20th century, coupling products at home and abroad have developed rapidly. In product design, how to choose a coupling that can meet the requirements of the machine from a variety of couplings with different performances? For most designers, It is always a troublesome problem. Commonly used couplings include diaphragm couplings, drum gear couplings, universal couplings, safety couplings, elastic couplings and serpentine spring couplings
CNC Machining for Shaft
Shafts, sleeves and disc parts are typical parts with outer surfaces. The commonly used mechanical processing methods for the outer surface include turning, grinding and various finishing methods. Turning processing is the most economical and effective processing method for the outer surface, but in terms of its economic accuracy, it is generally suitable for the rough and semi-finishing processing methods of the outer surface; due to the economic processing accuracy and surface that can be achieved by various processing methods Roughness, productivity, and production costs are different, so a reasonable processing method must be selected according to the specific situation, so as to process qualified parts that meet the requirements on the part drawings..

Cnc Machining Material For Shaft
The selection of shaft parts materials is mainly determined according to the strength, rigidity, wear resistance and manufacturing process of the shaft, and strives to be economical and reasonable. Commonly used materials for shaft parts are 35, 45, and 50 high-quality carbon steel, with 45 steel being the most widely used.
Ordinary carbon steels such as Q235 and Q255 can also be used for shafts with small or less important loads. Alloy steel can be used for larger forces, limited axial size and weight, or some special requirements. For example, 40Cr alloy steel can be used for medium-precision, high-speed work occasions, the material has better comprehensive mechanical properties after quenching and tempering treatment; the use of Cr15, 65Mn and other alloy steels can be used for high-precision and poor working conditions , These materials have good wear resistance and fatigue strength after quenching and tempering and surface quenching;
For shaft parts that work under high-speed and heavy-load conditions, use low-carbon steel such as 20Cr, 20CrMnTi, 20Mn2B, or 38CrMoA1A carburized steel. After carburizing and quenching or nitriding, these steels not only have high surface hardness, And the strength of its core is also greatly improved, so it has good wear resistance, impact toughness and fatigue resistance. Nodular cast iron and high-strength cast iron are often used in the manufacture of shafts with complex shapes and structures due to their good casting properties and vibration damping properties. In particular, the rare earth magnesium spheroidal graphite cast iron developed in my country has good impact resistance and toughness. It also has the advantages of friction reduction, vibration absorption, and low sensitivity to stress concentration. It has been used in the manufacture of important shaft parts for automobiles, tractors, and machine tools. .
