Hollow shaft is more and more people to use, then let's talk about what the advantages of what you loved by everyone
Hollow shaft occupies a relatively large volume of space, but can reduce the weight. According to the mechanical analysis of materials, in the shaft transmission torque, from the radial section to see, the more the place outside the effective torque transmission effect. In the shaft need to pass a larger torque, you need a thick shaft diameter. And because the role of the torque in the axial parts of the smaller, so the general use of hollow to reduce the weight of the shaft.
