| 摘 要： | 摆轮是手表的主要零件,由于它尺寸小,精度要求高,一般说来,它的产品合格率较低。本文运用数理统计方法,从摆轮游丝分档情况、加工质量对配档率的影响、机械设备能力以及摆轮偏心情况等四个方面进行了分析,找出了影响合格率的因素,并提出了改进措施。

| Abstract: | The balance wheel is the main part of a wrist watch. However, now its percent of pass is relatively low in our watch industry because of its small size and high precision. The present paper analyzes the quality indexes of the balance wheel in the following four aspects by using the method of mathematical statistics, the hair spring grading, the effect of machining on hair spring grading, the capability of equipment, and the eccentricity of the balance wheel. After finding out the factors which affect the qualities of the balance wheel, this paper proposes some measures to improve the existing process. |
