Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of mechanical watch movements, and in particular to a mechanical watch movement. Background Art
[0002] The tourbillon is a mechanical watch that rotates the escapement and speed regulating mechanism of the watch core under the drive of the tourbillon frame to offset the influence of gravity. Its structural characteristics are that the rotation axis of the escapement wheel is parallel to the axis of the tourbillon frame, the escapement rotates 360° around the axis of the tourbillon frame, and the axis of the tourbillon frame and the movement are set vertically. When the movement is placed vertically or worn, the escapement of the movement always rotates around the axis of the tourbillon frame, constantly changing its position to offset the influence of gravity on the escapement and speed regulating mechanism. When the movement is placed flat, the influence of the earth's gravity on the tourbillon movement and the ordinary movement is the same. This is also the general limitation of the two-axis tourbillon.
[0003] At present, the prior art has developed a three-axis tourbillon mechanism to solve the above technical problems. The Chinese patent publication number is CN103412471B, and the Chinese patent CN214011740U, which discloses a three-axis three-dimensional tourbillon mechanism, but its rotation about the Y-axis direction is mostly realized by bearings. Although it can meet the three-axis three-dimensional rotation, it is difficult to meet the problem of stable operation due to its structural characteristics. For example, the hollow bracket in CN214011740U is annular and the tourbillon frame is flat, so its center of gravity eccentricity will be relatively large, which leads to poor operation stability. And both of the above need to cooperate with the installation of bearing structure to meet the three-axis movement, that is, their structural characteristics need to match the transmission structure of the new structure to be realized. For the existing two-axis tourbillon movement, it is necessary to replace the entire movement to meet the purpose of three-axis rotation, and it is impossible to achieve the purpose of retaining the original movement structure and only replacing the tourbillon mechanism, which adds cost burden to the users of the old movement.
[0004] Therefore, there is an urgent need to develop a tourbillon mechanism that can offset the influence of gravity from the earth, so as to enhance the ability to overcome the earth's gravity and make mechanical watches more accurate. Summary of the invention
