螺旋式杠杆表表针转动时常常遇到卡住、跳动等现象,达不到技术要求,不能使用。我们通过更换一个φ1毫米的尼龙丝拨叉,代替了原有的钢制拨叉,就解决了这个问题。经使用8个月之久,仍然无卡住、跳动现象,示值误差也能保证1级精度。更换的方法是:用冲子把钢制拨叉沖下来,另剪一段φ1毫米长2毫米的尼龙丝插入孔内,使尼龙丝留在孔外长约1毫米,然后用502胶粘牢即可。当然。影响转动的其它毛病应事 Spiral lever watch table needle often encounter stuck, beating and other phenomena, can not meet the technical requirements, can not be used. We solved this problem by replacing a φ1 mm nylon yarn fork instead of the original steel fork. After 8 months of use, still no stuck, beating phenomenon, the indication error can also guarantee a level of accuracy. The replacement method is: Punch the steel fork rushed down, another cut a length of 2 mm φ1 mm nylon wire inserted into the hole, the nylon wire to stay in the hole about 1 mm long, and then bonded with 502 glue can . of course. Other problems affecting the rotation should be
