Mandrels

Mandrels

1. Support rotating parts: The main function of the mandrel is to support rotating parts, which is one of its most basic functions.
2. Only bear the bending moment without transferring the torque: the mandrel mainly bears the bending moment in the work, but does not transmit the torque. This means that the mandrel will not rotate as a result of transferring torque.
3. Classification: According to whether the work is rotated, the mandrel can be divided into rotating mandrel and fixed mandrel. The rotating mandrel will rotate with the rotating part being supported during operation, while the fixed mandrel will not rotate.
4. Application range: The application range of the mandrel is wide, including but not limited to the shaft of the railway vehicle, the shaft supporting the pulley, etc. In these applications, the role of the mandrel is to support the rotating part, but the specific rotation depends on its design and application scenario.
