数码相机的功能损坏大多与它的使用频率有关,尤其是机械部分—快门组件。使用频率高,该部件就运动多,故易出现各种故障。如镜头伸缩多了,它的PCB电路软带由于反复折叠收放累计疲劳出现断损故障;齿轮系统运转多了,齿轮磨损大,出现轴心不稳,齿间加大力矩,故易引起齿轴坏断,机构卡死故障。
The digital camera’s functional damage is mostly related to its frequency of use, especially the mechanical part - the shutter assembly. The use of high frequency, the parts on the movement, it is prone to various failures. Such as the lens more telescopic, its PCB circuit due to repeated folding folded plastic retractable accumulated fatigue failure; gear system running more, gear wear large, there axis instability, increase the torque between the teeth, it is easy to cause the tooth Broken shaft, the body stuck stuck.
