However, there are also a few cases where the shaft has a square shape. Here are the classifications and characteristics of shafts that have been compiled for you. We hope this information can be helpful!

1. Classification and Characteristics of Shafts

Commonly, shafts can be classified based on their structural shape as crankshafts, straight shafts, flexible shafts, solid shafts, hollow shafts, rigid shafts, and flexible shafts.

2. Straight shafts can be further categorized as follows: 

Rotating shafts: These shafts bear both bending and torsional loads and are the most commonly used shafts in machinery, such as the shafts in various types of gear reducers.

3. Spindle shafts: These shafts are used to support rotating components and only bear bending loads without transmitting torque. Some spindle shafts rotate, such as the axles of railway vehicles, while others do not rotate, such as the shafts supporting pulleys.

4. Drive shafts: These shafts are primarily used to transmit torque without bearing bending loads, such as the long drive shafts in crane moving mechanisms or the drive shafts in automobiles.

Shafts are typically made of carbon steel or alloy steel. Other materials, such as ductile iron or alloy cast iron, can also be used. The working capacity of a shaft generally depends on its strength and rigidity, and for high-speed applications, it also depends on vibration stability.
