Description

一种机械手表的三轴陀飞轮机构 技术领域  Three-axis tourbillon mechanism for mechanical watches
本发明涉及一种机械手表的陀飞轮机构，特别是涉及一种机械手表的三轴陀 飞轮机构。  The present invention relates to a tourbillon mechanism for a mechanical wristwatch, and more particularly to a three-axis tourbillon mechanism for a mechanical wristwatch.
背景技术  Background technique
陀飞轮的结构特点是将机械表最核心的调速机构在陀飞轮框架的带动下旋 转， 以抵消重力的影响， 专利公开号 CN102809919A公开了一种双轴陀飞轮， 它的 结构特点是内轴框架的旋转轴心线与外轴框架的旋转轴心线垂直设置，外框架的 旋转轴心线垂直于与机芯的轴心线，搭载调速机构的内轴陀飞轮在外轴框架的带 动下， 既以外轴轴心线公转又以内轴轴心线自转， 使得擒纵机构和摆轮游丝*** 的运动轨迹变得复杂。其运动轨迹与单轴陀飞轮相比变得更加复杂， 最大的优势 在于调速机构的运动轨迹越复杂，抵消地心引力的能力就会越明显， 最终的结果 是多轴陀飞轮机械表的走时精度可以被提升。但上述双轴陀飞轮的运动轨迹近似 柱状立体运动， 调速机构的运动轨迹只能在有限的立体空间变换。  The structure of the tourbillon is characterized by rotating the core speed governing mechanism of the mechanical watch under the tourbillon frame to counteract the influence of gravity. Patent Publication No. CN102809919A discloses a two-axis tourbillon, which is characterized by an internal shaft. The rotation axis of the frame is perpendicular to the axis of rotation of the outer frame, the axis of rotation of the outer frame is perpendicular to the axis of the movement, and the inner axle tourbillon with the speed governing mechanism is driven by the outer frame. , the outer shaft axis revolves and the inner shaft axis rotates, which makes the movement path of the escapement mechanism and the balance spring system complicated. The trajectory of the trajectory is more complicated than that of the single-axis tourbillon. The biggest advantage is that the more complex the trajectory of the governor mechanism, the more obvious the ability to offset the gravity, and the final result is the multi-axis tourbillon mechanical watch. The travel time accuracy can be improved. However, the motion trajectory of the above-mentioned two-axis tourbillon approximates the cylindrical three-dimensional motion, and the motion trajectory of the speed governing mechanism can only be transformed in a limited three-dimensional space.
为了更好地抵消来自于地球的重力影响， 目前已研发出一种三轴陀飞轮， 它 是在双轴陀飞轮结构基础上增加了第三根旋转轴，带来的效果是陀飞轮的运动轨 迹接近球形，使得陀飞轮内部的调速机构可以运动到任意的方向， 以此来提升克 服地球引力的能力。 但是， 现有三轴陀飞轮的结构存在以下缺陷： 首先， 第三轴 采用上下支承方式， 此种结构会占用更多的轴向空间， 使得表的厚度增加很多， 对于佩戴者来说很不方便； 其次， 第三轴采用滚珠轴承下支承方式。手表中使用 的专用滚珠轴承尺寸小， 而且薄， 并非普通滚珠轴承縮小所能实现的功能； 在陀 飞轮机构中的滚珠轴承要承载陀飞轮的高速运转，因此滚珠轴承的磨损是目前一 个无法克服的缺陷，一些能有效抵抗磨损的高精度滚珠轴承的制造难度和价格是 非常高的。  In order to better offset the influence of gravity from the earth, a three-axis tourbillon has been developed, which adds a third rotating shaft to the structure of the two-axis tourbillon, which brings the effect of the tourbillon. The trajectory is close to a spherical shape, so that the governing mechanism inside the tourbillon can move to any direction, thereby improving the ability to overcome the gravity of the earth. However, the structure of the existing three-axis tourbillon has the following drawbacks: First, the third shaft adopts an up-and-down support mode, which occupies more axial space, which increases the thickness of the watch, which is inconvenient for the wearer. Secondly, the third shaft adopts the support method of the ball bearing. The special ball bearings used in watches are small in size and thin, which is not the function that can be achieved by shrinking ordinary ball bearings. The ball bearings in the tourbillon mechanism are required to carry the high speed operation of the tourbillon, so the wear of the ball bearings is currently insurmountable. The drawbacks and the high difficulty and price of some high-precision ball bearings that are effective against wear are very high.

本发明机械手表的三轴陀飞轮机构实施例 1的工作过程说明如下： 动力输入轮 15带动驱动轮 1旋转。 由于驱动轮 1与轴承架 6相互固定， 并 且圆柱滚子架部件、 内环 9和太阳轮 12组成了圆柱滚子轴承， 被设置在驱动轮 1上的外轴框架 13和内轴陀飞轮 14以太阳轮 12的轴心线为轴旋转。 由于行星 轮 3与太阳轮 12是啮合关系， 行星轮 3围绕太阳轮 12公转， 同时以外轴框架 13的轴心线自转。 双轴陀飞轮的工作过程可参见专利号 CN102809919A "机械手 表的双轴陀飞轮机构"。在第三轴的驱动下内轴陀飞轮 14每 1分钟转动一周， 外 轴框架 13每 2. 5分钟转动一周，外轴框架 13每转动一周所用的时间可以为 2-10 分钟之间，第三轴的旋转速度为每 9分钟转动一周，此值的可选取范围是在 5-15 之间。  The operation of the three-axis tourbillon mechanism of the mechanical watch of the present invention is explained as follows: The power input wheel 15 drives the drive wheel 1 to rotate. Since the drive wheel 1 and the bearing frame 6 are fixed to each other, and the cylindrical roller frame member, the inner ring 9 and the sun gear 12 constitute a cylindrical roller bearing, the outer shaft frame 13 and the inner shaft tourbillon 14 are disposed on the drive wheel 1. The axis of the sun gear 12 is rotated about the axis. Since the planetary gear 3 is in meshing relationship with the sun gear 12, the planetary gear 3 revolves around the sun gear 12 while the axis of the outer frame 13 rotates. The working process of the two-axis tourbillon can be found in the patent number CN102809919A "Double-axis tourbillon mechanism of the robot table". The inner shaft tourbillon 14 is rotated once every one minute under the driving of the third shaft, and the outer shaft frame 13 is rotated once every 2.5 minutes, and the time taken for each rotation of the outer shaft frame 13 can be between 2 and 10 minutes. The triaxial rotation speed is one revolution every 9 minutes, and the value can be selected between 5-15.
本发明机械手表的三轴陀飞轮机构实施例 2的工作过程说明如下： 动力输入轮 15带动驱动轮 1旋转。 由于驱动轮 1与轴承架 6相互固定， 并 且圆柱滚子架部件、 内环 9和太阳轮 12组成了圆柱滚子轴承， 被设置在驱动轮 1上的内轴陀飞轮 14自转， 同时以太阳轮 12的轴心线为轴公转。 本发明由于第三轴的结构为下支承方式， 因此， 在提高走时精度的同时， 也未增加手表厚度， 依然保持手表的小巧， 美观； 另外， 第三轴总体结构工艺性 强， 特别是圆柱滚子轴承加工简单， 零件加工成本低， 适合批量工业化生产； 三 轴陀飞轮的运动轨迹从柱状升级为球状， 内部的调速机构为立体式多角度运动， 运动轨迹更加复杂， 抵消地球引力的效果更加明显， 机械表走时更加精准。 The working process of the three-axis tourbillon mechanism of the mechanical watch of the present invention is explained as follows: The power input wheel 15 drives the drive wheel 1 to rotate. Since the drive wheel 1 and the bearing frame 6 are fixed to each other, and the cylindrical roller frame member, the inner ring 9 and the sun gear 12 constitute a cylindrical roller bearing, the inner shaft tourbillon 14 disposed on the drive wheel 1 rotates while the sun The axis of the wheel 12 is the axis revolution. Because the structure of the third shaft is the lower support mode, the invention not only increases the thickness of the watch, but also keeps the watch small and beautiful while improving the travel time precision; in addition, the overall structure of the third shaft is strong, especially the cylinder. The roller bearing is easy to process, low in part processing cost, and suitable for mass industrial production. The trajectory of the three-axis tourbillon is upgraded from a column to a ball. The internal speed governing mechanism is a three-dimensional multi-angle motion, and the movement trajectory is more complicated, offsetting the gravity of the earth. The effect is more obvious, and the mechanical watch is more precise.
值得指出的是， 本实施例采用的是同轴式陀飞轮， 而本发明的保护范围并不 局限于上述具体实施方式，根据本发明的基本技术构思， 也可以采用基本相同的 结构传动， 而选用偏心式陀飞轮依然可以实现本发明的目的， 只要本领域普通技 术人员无须经过创造性劳动，即可联想到的实施方式，均属于本发明的保护范围。  It should be noted that the present embodiment uses a coaxial tourbillon, and the scope of protection of the present invention is not limited to the above specific embodiments. According to the basic technical idea of the present invention, substantially the same structure transmission can also be adopted. The object of the present invention can still be achieved by using an eccentric tourbillon, and any embodiment that can be conceived by those skilled in the art without creative labor is within the scope of the present invention.
