编译一个关于 Cal.2500A 同轴擒纵机芯擒纵部分的润滑要求,这个部分很重要。(付中英对照,各取所需)
Lubrication of the escapement(擒纵轮的润滑)
The escapement lubrification must be checked with a microscope. We recommend lubricating the escapement directly under the microscope.
(检查擒纵轮的润滑必须在显微镜下进行,我们建议做擒纵润滑时在显微镜下进行。)
Escape wheel:(擒纵轮:)
Put a very small drop of D5 on the tip of one tooth and then move the escapement one tooth forward.
(加非常小的D5油滴在齿尖上,然后将擒纵轮向前移动一格。)
Repeat this procedure 8x in order that all teeth are lubricated.
(重复这个动作8次,直到所有的齿得到润滑。)
Quantity:(油量:)
The tolerances for the lubrication quantities are shown on picture below.
(油量控制如下图,至mini线为最小,至maxi为最大。)
