问:分轴擒纵的特点有哪些? Q: What are the features of di-axial escapement?
答:分轴擒纵吸收并发扬了钟表史上三种擒纵的部分精华理论,1:保留了现代杠杆擒纵(Lever Escapement)的锁齿功能,驱动摆轮旋转的功能分别另外设立两个冲击叉瓦来完成;2:吸收并革新了复式擒纵(Duplex Escapement)的理论,作为左冲击叉瓦,3:吸收并革新了天文台擒纵(Detent Escapement)的游丝复位理论,作为右冲击驱动摆轮叉瓦。分轴擒纵主要在三个方面改进了性能:1、相同尺寸和形状的双层擒纵轮避免了上层擒纵轮因直径小,冲击距离短,冲击力量弱,擒纵轮齿与冲击叉瓦间隙小而容易发生碰擦顶齿的现象。2、相同尺寸和形状的双层擒纵轮使擒纵左右运行的步伐更加均衡。3、相同尺寸和形状的双层擒纵轮在长时间运行后产生的磨损是均匀的。分轴擒纵是一个效率很高的,工作可靠,并且是可以推广应用的实用型的擒纵。 A: The di-axial escapement absorbs and highlights some of the essential theories in the history of watch about the three escapements, including: 1. That it keeps the lock gear function of modern lever escapement, and designs two impact fork tiles to realize the function of driving the balance wheel to rotate; 2. That it absorbs and innovates the theory of duplex escapement, and functions as the left impact fork tile; 3. That it absorbs and innovates the hairspring reset theory of detent escapement, and functions as the right impact fork tile to drive the balance wheel. The di-axial escapement mainly improves the functions in three aspects, including: 1. The double plates of the escapement wheel in the same size avoid the highly probable collision and friction between the upper escapement wheel and the top gear because of the small diameter, short impact distance, low impact force and small gap between the escape wheel gear and the impact fork tile. 2. The double plates of the escapement wheel in the same size enable more balanced pace of the left and right escape wheel operation. 3. The double plates of the escapement wheel in the same size have even abrasion after long-term operation. Therefore, the di-axial escapement is a kind of practical escapement characterized by high efficiency, reliable operation and good applicability.
