一台长城牌石英钟,装上电池后其秒针走不到一圈即出现停走原地摆动现象(俗称鸡啄米),而且每次试机时停走位置不固定。经仔细检查,发现石英钟秒钟轴偏心,从而与分针轴套相碰,产生一定的阻尼,造成秒针停走原地摆动。 A Great Wall brand quartz clock, installed on the battery after the second hand to go less than a circle that appears to stop walking swinging phenomenon (commonly known as chicken peck meters), and stop each stop when the test location is not fixed. After careful examination, it was found that the quartz clock second shaft eccentric, and thus meet with the minute hand shaft sleeve, resulting in some damping, causing the second hand to stop walking in situ swing.
