What is the principle of the damping spindle on the laptop?

The principle of the damping spindle: in fact, it is through the squeeze between the shims and shims to generate friction, the size of the friction is the number of shims installed in the number of nuts screwed tightly related.

Damping spindle common problems:

Damping spindle is the most common problem is the most common problem of the spindle spacer wear is also common in the use of the spindle shaft equipment problems, mainly spindle spacer metal characteristics caused by: metal, although the hardness of the high, but poor concessions (deformation can not be restored), poor impact resistance, poor fatigue resistance, therefore, easy to cause adhesive wear, abrasive materials, and the use of the spindle spacer, the spacer can not be used. Easy to cause adhesive wear, abrasive wear, fatigue wear, micromotion wear, etc..

Most of the damping shaft wear is not easy to notice, only when there is a damping arbitrarily stay in the amplitude of large, strange noise, etc., will cause to notice, but to people find, most of the drive shaft has been worn out, so that the damping effect becomes smaller. Damping shaft structure:

Damping shaft structure according to different application scenarios and categorization can be divided into: a word type damping shaft, wrapped damping shaft, shrapnel type damping shaft.
