The damping shaft is simply a shaft with damping. It is defined as the shaft that must be used to link product components and is used to bear both bending and torque during rotation work. It is called a damping shaft.

The principle of damping shaft:

The principle of the damping shaft is actually the friction generated by the compression between the seal and the seal. The friction depends on the number of seals installed and the tightness of the nut. For example, when we open the screen of a laptop computer, the hinge of the laptop computer needs a certain amount of force, and this force does not need to be great. When we stop rotating, the screen will not shake up and down, but depends on the friction on the hinge. Place the notebook screen where you want.

Damping shaft structure:

The damping shaft structure can be divided into different application scenarios and classifications: inline damping shaft, wrapped damping shaft, shrapnel damping shaft,

Application of damping shaft:

Common damping shafts include: notebook damping shaft, mobile phone damping shaft, desk lamp damping shaft, display damping shaft, camera damping shaft, pos machine damping shaft, etc.

Common problems with damping shaft:

The most common problem of damping shafts is the wear and tear of the seals between the shafts, which are also common equipment problems when using shafts. It is mainly caused by the metal characteristics of the shaft seal: although the metal has high hardness, it has poor shrinkage (cannot be restored after deformation), poor impact resistance and fatigue resistance, so it is easy to cause adhesive wear, abrasive wear, fatigue wear, friction wear, etc. Most damper shafts are not easily detectable for wear. Only when the damping is maintained at a large amplitude or abnormal noise, etc., will it be noticed. However, when it was discovered, most of the drive shafts were worn out, reducing the damping effect.
