Description

Technical Field

[0001] This utility model relates to the technical field of mechanical watch movements, specifically to a mechanical watch movement. Background Technology

[0002] A tourbillon uses the escapement and regulating mechanism of a mechanical watch movement, driven by the tourbillon cage, to counteract the effects of gravity. Its structural features include the escapement wheel's axis of rotation being parallel to the tourbillon cage's axis, the escapement mechanism rotating 360° around the tourbillon cage's axis, and the tourbillon cage's axis being perpendicular to the movement. When the watch is placed upright or worn, the escapement mechanism constantly rotates around the tourbillon cage's axis, continuously changing its position to counteract the effects of gravity on the escapement and regulating mechanism. When the watch is placed flat, the effects of gravity on a tourbillon movement are the same as on a regular movement. This is a common limitation of dual-axis tourbillons.

[0003] Currently, existing technologies have developed three-axis tourbillon mechanisms to solve the aforementioned technical problems. Chinese patent publications CN103412471B and CN214011740U both disclose a three-axis three-dimensional tourbillon mechanism. However, their rotation in the Y-axis direction is mostly achieved through bearings. While this satisfies the three-axis three-dimensional rotation, its structural characteristics make it difficult to ensure stable operation. For example, in CN214011740U, the hollow support is ring-shaped, and the tourbillon frame is flat, resulting in a relatively large center of gravity eccentricity, leading to poor operational stability. Furthermore, both require the installation of bearing structures to achieve three-axis motion. This means that the structural characteristics necessitate a new transmission structure. For existing two-axis tourbillon movements, this requires replacing the entire movement to achieve three-axis rotation, failing to achieve the goal of retaining the original movement structure and only replacing the tourbillon mechanism, thus increasing the cost burden for users of older movements.

[0004] Therefore, there is an urgent need to develop a tourbillon mechanism that can counteract the effects of Earth's gravity, in order to improve the ability to overcome Earth's gravity and make mechanical watches more accurate. Utility Model Content

[0005] To address the aforementioned problem—the effect of gravity on a biaxial tourbillon movement when placed on a flat surface—this invention proposes a mechanical watch movement comprising, from top to bottom, a middle plate, a third plate, a lower plate, and a base plate. A fourth power drive assembly is rotatably connected between the middle and base plates. A second wheel assembly is rotatably connected between the middle and lower plates, with the barrel wheel of the fourth power drive assembly meshing with the second gear of the second wheel assembly.

A seconds hand rest assembly is screwed to the lower plate, and a seconds gear is rotatably connected between the seconds hand rest assembly and the base plate. The third wheel of the third wheel assembly meshes with the seconds gear. The seconds gear is positioned in the middle of the base plate, with its tip extending beyond the seconds hand rest assembly and interference-fitted with a seconds hand support for driving the movement. The second axis support rotates, and a fixed planetary mechanism and a movable planetary mechanism are provided on the upper edge of the second axis support. The fixed planetary mechanism and the movable planetary mechanism are symmetrically arranged about the second gear axis. An orbital wheel is also fixedly connected to the middle clamp plate, and the orbital wheel is coaxially arranged with the second gear axis. The movable planetary wheel of the movable planetary mechanism meshes with the orbital wheel. The fixed planetary mechanism includes a fixed planetary wheel. A spherical frame is provided between the fixed planetary wheel and the movable planetary wheel. The spherical frame is rotatably arranged with the fixed planetary wheel and fixedly arranged with the movable planetary wheel. A second clamp plate connector is rotatably connected to the bottom of the spherical frame. A fixed second wheel plate is fixedly connected to the spherical frame. A pendulum clamp plate is fixedly connected to the second clamp plate connector through a second clamp plate component. The pendulum clamp plate meshes with the fixed planetary wheel. An escapement mechanism is provided on the second clamp plate component, and the fixed second wheel plate meshes with the escape wheel component of the escapement mechanism.

[0006] A further feature of the utility model is that the escapement mechanism includes an escape fork clamp, an escape fork component, and an escape wheel bracket. The escape fork clamp is connected to the seconds clamp component by screws. The escape fork component is disposed between the escape fork clamp and the seconds clamp component. The escape wheel bracket is disposed on the seconds clamp component. The escape wheel component is rotatably connected between the escape fork clamp and the escape wheel bracket. The escape wheel component includes an escape gear shaft, which meshes with the fixed seconds wheel, and the axis of the escape gear shaft is parallel to the axis of the fixed seconds wheel.

[0007] A further feature of this invention is that a lower shock absorber is provided in the central hole of the second clamping plate component, an upper shock absorber is provided in the central hole of the pendulum clamping plate, and a speed regulating component is provided between the upper shock absorber and the lower shock absorber; a mounting ring is also provided inside the pendulum clamping plate, and an outer stake is connected to the mounting ring by screws, and the hairspring of the speed regulating component is clamped between the mounting ring and the outer stake.

[0008] A further feature of this invention is that: a through hole is provided at the center of the second clamp plate connector, a fixed shaft passes through the through hole, the second clamp plate connector is rotatably connected to the fixed shaft, the bottom end of the fixed shaft passes through the spherical frame and is threaded with a screw component; a square tenon is provided at the top end of the fixed shaft, a threaded hole is provided on the square tenon, a square hole adapted to the square tenon is provided at the axis of the fixed second wheel, the square hole is fitted onto the square tenon, and a screw is threadedly connected to the threaded hole on the square tenon to fix the fixed second wheel to the fixed shaft.

[0009] A further feature of this invention is that a mounting plate is coaxially connected to the middle clamping plate by screws, and the track wheel is coaxially connected to the upper surface of the mounting plate by screws.

[0010] The present invention is further configured as follows: the fixed planetary mechanism includes a fixed planetary support, which is connected to the upper edge of the second axis support by screws, and the fixed planetary gear is interference-fitted to the inner side of the fixed planetary support; a fixed planetary shaft is also rotatably connected to the inner side of the fixed planetary support, the fixed planetary shaft passing through the fixed planetary gear, and the end of the fixed planetary shaft opposite to the fixed planetary support is interference-fitted to the spherical frame; the movable planetary mechanism includes a movable planetary support, which is connected to the upper edge of the second axis support by screws, and a movable planetary shaft is rotatably connected to the movable planetary support, with both ends of the movable planetary shaft respectively disposed on both sides of the movable planetary support, wherein the end of the movable planetary shaft near the spherical frame is interference-fitted to the spherical frame, and the movable planetary gear is fixedly connected to the other end of the movable planetary shaft; the fixed planetary shaft and the movable planetary shaft are coaxially arranged.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This application defines the direction of the second gear axis as the Z-axis, the direction of the moving planetary axis as the X-axis, and the direction of the fixed axis as the Y-axis, so as to achieve a spherical motion trajectory, allowing the speed regulating components inside the tourbillon to move in any direction, thereby improving the ability to overcome gravity. Regardless of whether the movement is placed flat or vertically, it can counteract gravity from any position. Furthermore, the rotational speeds around each axis are reasonably set.

[0013] 2. By setting up a second axis support and a spherical frame, the movement of the mechanism can be made more stable, the torque transmission is smoother, and the operation is more stable and reliable. At the same time, due to the cooperation between the bowl-shaped second axis support and the spherical frame in this application, the center of gravity of the mechanism can be closer to the axis, the eccentricity is smaller, and thus its running trajectory can be closer to a sphere, further ensuring the accuracy of its running trajectory.

[0014] 3. The transmission mechanism via the seconds gear shaft enables the tourbillon mechanism to move, allowing it to work in conjunction with traditional transmission mechanisms. This means that simply replacing the tourbillon mechanism in a traditional biaxial tourbillon movement allows for three-dimensional rotation, further simplifying the replacement of biaxial tourbillon mechanisms and saving users significant movement replacement costs. Furthermore, because the seconds gear shaft directly drives the seconds shaft support, bearings and other parts are eliminated, reducing the number of parts and allowing for a smaller seconds shaft support, thus optimizing the movement structure. Jewels are also placed at each rotating connection point to reduce friction and extend the lifespan of the components. Attached Figure Description

[0054] It should be noted that gemstones are provided at each rotating connection to reduce friction loss during rotation and further improve the service life of the parts. Since gemstones are a common practice in this field, they will not be described in detail here.

[0055] refer to Figure 19 It is a traditional two-axis tourbillon movement. When replacing it with the tourbillon mechanism disclosed in this application, it is only necessary to replace the four-tooth shaft 26 together with the tourbillon mechanism on it with the tourbillon mechanism and the second tooth shaft 4 in this application.

[0056] In summary, this invention defines the direction of the second gear axis 4 as the Z-axis, the direction of the moving planetary axis 6-3 as the X-axis, and the direction of the fixed axis 17 as the Y-axis, so as to achieve a spherical motion trajectory, allowing the speed regulating component (12) inside the tourbillon to move in any direction, thereby improving the ability to overcome the Earth's gravity. Regardless of whether the movement is placed in a flat or vertical position, it can counteract gravity at any position. Furthermore, the rotational speeds around each axis are reasonably set. By setting the second gear support and the spherical frame, the movement of the movement can be made more stable, the torque transmission can be smooth, and the operation can be more stable and reliable.

[0057] By setting the second axis support 5 and the spherical frame 8, the movement of the mechanism can be made more stable, the torque transmission is smoother, and the operation is more stable and reliable. At the same time, due to the cooperation between the bowl-shaped second axis support 5 and the spherical frame 8 in this application, the center of gravity of the mechanism can be closer to the axis, the eccentricity is smaller, and thus its running trajectory can be closer to a sphere, further ensuring the accuracy of its running trajectory.

[0058] The transmission mechanism via the second gear 4 drives the tourbillon mechanism, allowing it to engage with traditional transmission mechanisms. This enables the direct replacement of the tourbillon mechanism in a traditional biaxial tourbillon movement, achieving three-dimensional rotation and providing a seamless alternative to biaxial tourbillon mechanisms, significantly reducing the cost of replacing the movement. Furthermore, because the second gear 4 directly drives the second gear support, bearings and other parts are eliminated, reducing the number of components and allowing for a smaller second gear support, thus optimizing the movement structure. Jewels are also placed at each rotating connection point to reduce friction and extend the lifespan of the components.
