Description
A dual-axis tourbillon structure with adjustable moment of inertia Technical Field
[0001] This application relates to the technical field of mechanical watch tourbillons, and in particular to a dual-axis tourbillon structure with adjustable moment of inertia. Background Technology
[0002] In the mechanical watchmaking industry, the tourbillon is a device that reduces isochronism errors. This device features a balance wheel and hairspring system and escapement mechanism housed within a frame, rotating with the frame while simultaneously operating independently. This minimizes positional errors caused by gravity, thereby improving timekeeping accuracy. Traditional single-axis tourbillons have been around for many years; however, with technological advancements and diversified consumer demands, they can no longer meet higher-level requirements, especially in complex and changing wearing environments. More advanced tourbillon structures are needed to further enhance performance.
[0003] To address this challenge, one related technology involves adding a second axis of rotation to the existing single-axis tourbillon, forming a dual-axis tourbillon structure to further counteract the effects of gravity in different directions. However, while the dual-axis tourbillon in this technology can further reduce the effects of gravity, it is still difficult to flexibly adjust the moment of inertia of the balance wheel in practical applications, resulting in limited adaptability to different environments. Summary of the Invention
[0004] To flexibly adjust the moment of inertia of the balance wheel, this application provides a dual-axis tourbillon structure with adjustable moment of inertia.
[0005] The dual-axis tourbillon structure with adjustable moment of inertia provided in this application adopts the following technical solution:
[0006] A dual-axis tourbillon structure with adjustable moment of inertia includes a frame, a first direction axis, an outer tourbillon, a second direction axis, an inner tourbillon, an escapement mechanism, and a gear train. The outer tourbillon is rotatably connected to the frame via the first direction axis, and the axis of the outer tourbillon is perpendicular to the first direction axis. The inner tourbillon is rotatably connected to the outer tourbillon via the second direction axis, and the axes of the outer tourbillon, the inner tourbillon, and the second direction axis are all collinear. The escapement mechanism is located on the inner tourbillon and includes an escape wheel, an escape fork, and a balance wheel. The surface of the balance wheel has four adjusting posts evenly spaced around its circumference. C-shaped weights are fitted around the adjusting posts, and the C-shaped weights are interference-fitted with the adjusting posts. The gear train is used to drive the outer tourbillon to rotate around the first direction axis, the inner tourbillon to rotate around the second direction axis, and the escape wheel to rotate simultaneously.
[0007] By employing the aforementioned technical solution, this dual-axis tourbillon structure achieves rotational motion in two directions, improving the timekeeping accuracy and stability of the mechanical watch. The outer and inner tourbillons rotate around axes in two different directions, allowing the entire system to counteract the effects of gravity in multiple directions. Simultaneously, the balance wheel surface in the escapement mechanism is equipped with four adjusting pillars and C-shaped weights. Adjusting the angle of the C-shaped weights changes the system's moment of inertia, thereby achieving precise time control. The design of the gear train ensures coordinated movement between the outer tourbillon, inner tourbillon, and escapement wheel, further enhancing the system's stability and reliability.
[0008] Optionally, the first direction axis includes a moving side axis and a stationary side axis arranged collinearly. The moving side axis is used to receive power, and the stationary side axis is used to provide support. The clamping plate is provided with a moving side stationary axis frame and a stationary side stationary axis frame. The moving side axis and the stationary side axis are rotatably connected to the moving side stationary axis frame and the stationary side stationary axis frame respectively through a moving side jewel bearing and a stationary side jewel bearing. A moving side moving axis frame is fixedly connected to the moving side axis, and a stationary side moving axis frame is fixedly connected to the stationary side axis. Both the moving side moving axis frame and the stationary side moving axis frame are fixedly connected to the outer tourbillon.
[0009] By adopting the above technical solutions, the separate design of the moving side shaft and the stationary side shaft not only effectively separates the power transmission and support functions, but also facilitates shaft surface grinding, thereby improving the surface finish. The application of moving side and stationary side jewel bearings further reduces friction loss and extends service life. In addition, the design of the moving side shaft holder and the stationary side shaft holder ensures a stable connection of the outer gyroscope, enhancing the rigidity and seismic resistance of the overall structure.
[0010] Optionally, the transmission gear train includes an axial transmission system for driving the outer gyroscope to rotate around the first direction axis. The axial transmission system includes a driving wheel, an axial source driving wheel, and an axial driven wheel. The axial source driving wheel is rotatably connected to the frame plate around its own axis. The driving wheel and the axial source driving wheel are coaxially arranged and can rotate synchronously. The axial driven wheel is coaxially arranged and can rotate synchronously with the moving side axis. The axial driving wheel and the axial driven wheel mesh with each other.
[0011] By adopting the above technical solution, the driving wheel and the axial source driving wheel are coaxially arranged and can rotate synchronously. When the driving wheel receives power, this power is transmitted to the axial source driving wheel, causing the axial source driving wheel to start rotating around its own axis. When the axial source driving wheel rotates, it transmits power to the axial driven wheel through a meshing relationship. Since the axial driven wheel and the moving side shaft are coaxially arranged and can rotate synchronously, the rotation of the axial driven wheel drives the moving side shaft to rotate together. When the moving side shaft rotates, its externally fixed moving side shaft bracket also rotates. Since the moving side shaft bracket is fixedly connected to the outer gyroscope, the rotation of the moving side shaft bracket will drive the outer gyroscope to rotate around the first direction axis. At the same time, the stationary side shaft, as a support part, is rotatably connected to the stationary side stationary shaft bracket through the stationary side jewel bearing, ensuring the stability of the moving side shaft during rotation. The stationary side moving shaft bracket, which is externally fixedly connected to the stationary side shaft, is also fixedly connected to the outer gyroscope, further enhancing the stability of the outer gyroscope. Throughout the transmission process, the application of the moving side jewel bearing and the stationary side jewel bearing reduces friction loss, improves transmission efficiency, and extends service life. The separate design of the moving side shaft and the stationary side shaft facilitates the grinding of the shaft surface, improves the surface finish of the shaft, and thus further enhances the stability and reliability of the transmission.
[0012] Optionally, the second direction axis is rotatably connected to the outer tourbillon about its own axis. One end of the second direction axis is integrally formed with a planetary carrier, and the other end is used to receive power. The planetary carrier is fixedly connected to the inner tourbillon.
[0013] By adopting the above technical solution, the second direction axis can be rotatably connected to the outer tourbillon around its own axis, allowing the inner tourbillon to rotate stably around the second direction axis. One end of the second direction axis has an integrally formed planetary carrier fixedly connected to the inner tourbillon, ensuring reliable linkage between the inner tourbillon and the second direction axis, and improving the mechanical precision and stability of the entire system. The other end is designed to receive power, ensuring effective power transmission and enabling the inner and outer tourbillons to work together to achieve more complex motion modes.
[0014] Optionally, the transmission gear train includes a circumferential transmission system for driving the inner gyroscope to rotate about the second direction axis. The circumferential transmission system includes a circumferential driving wheel, a circumferential driven wheel, a steering synchronizing wheel, a steering driving wheel, and a steering stationary wheel. The circumferential driving wheel is fixedly connected to the end of the second direction axis away from the planetary carrier. The circumferential driven wheel and the steering driving wheel are rotatably connected to the outer gyroscope about their own axes. The steering synchronizing wheel is coaxially connected to the steering driving wheel and can rotate synchronously with the steering driving wheel. The circumferential driven wheel meshes with both the steering synchronizing wheel and the circumferential driving wheel. The axes of the circumferential driving wheel, the circumferential driven wheel, and the steering driving wheel are parallel to each other. The steering stationary wheel is fixedly connected to the stationary side frame and coaxially arranged with the first direction axis. The steering stationary wheel meshes with the steering driving wheel.
[0015] By adopting the above technical solution, the steering wheel, through its rotational connection with the outer gyroscope, can revolve around the first direction axis along with the outer gyroscope as the outer gyroscope rotates around it. The steering stationary wheel, because it is fixedly connected to the stationary side frame and coaxially arranged with the first direction axis, is stationary relative to the outer gyroscope and the steering wheel; that is, its position does not change with the rotation of the outer gyroscope. Therefore, when the steering wheel revolves with the rotation of the outer gyroscope, the steering wheel and the steering stationary wheel achieve transmission through meshing; that is, the steering stationary wheel drives the steering wheel to rotate around its own axis. After the steering wheel begins to rotate around its axis, because the steering synchronizing wheel is coaxially connected to the steering wheel and can rotate synchronously with it, and because the steering synchronizing wheel meshes with the circumferential driven wheel, the circumferential driven wheel also rotates accordingly. The circumferential driven wheel simultaneously meshes with the circumferential source wheel, which is fixedly connected to the end of the second directional axis furthest from the planet carrier. Therefore, the circumferential source wheel and the second directional axis also rotate along with the circumferential driven wheel. Simultaneously, the rotation of the second directional axis drives the planet carrier and the inner gyroscope to rotate together around the second directional axis. The fixed connection between the planet carrier and the inner gyroscope ensures reliable linkage between the inner gyroscope and the second directional axis.
[0016] Optionally, the escapement mechanism further includes an escapement frame, wherein the escape wheel, the escape fork, and the balance wheel are all disposed on the escapement frame, and the escapement frame is fixedly connected to the inner gyroscope.
[0017] By adopting the above technical solution, the escape wheel, escape fork, and balance wheel are connected to the escapement frame, enabling these components to operate stably under the constraint of the escapement frame. Simultaneously, the escapement frame is fixedly connected to the inner gyroscope, ensuring that the escape mechanism moves together with the inner gyroscope, achieving precise time adjustment.
[0018] Optionally, the transmission gear train includes an escapement drive system for driving the escape wheel to rotate. The escapement drive system includes a sun gear and an escapement input wheel. The sun gear is fixed on the side of the outer tourbillon near the first direction axis. The sun gear is coaxially arranged with the second direction axis and rotatably connected to the second direction axis through a central jewel bearing. The escape wheel is coaxially fixedly connected to the escapement input wheel, and the escapement input wheel meshes with the sun gear.
[0019] By adopting the above technical solution, when the circumferential driving wheel receives power and begins to rotate, it drives the second direction axis to rotate as well. Since the planetary carrier and the second direction axis are integrally formed and fixedly connected to the inner gyroscope, the inner gyroscope also rotates with the rotation of the second direction axis. The escapement transmission system includes a sun gear and an escapement input wheel. The sun gear is fixed on the side of the outer gyroscope near the first direction axis, coaxially arranged with the second direction axis, and rotatably connected to the second direction axis via a central jewel bearing. Therefore, the sun gear is stationary relative to the inner gyroscope, meaning its position does not change with the rotation of the inner gyroscope. The escape wheel is located on the escapement carrier, which is fixedly connected to the inner gyroscope. The escape wheel is coaxially fixedly connected to the escapement input wheel. Therefore, when the inner gyroscope rotates, both the escape wheel and the escapement input wheel revolve around the sun gear, which is coaxially arranged with the second direction axis. The escapement input wheel meshes with the sun gear, so when the escapement input wheel revolves around the sun gear, it also rotates on its own axis under the meshing action, thereby driving the escape wheel to rotate as well. When the escape wheel rotates, it drives the escapement mechanism, which includes the escape fork and the balance wheel, to start working.
[0020] Optionally, the axial driving wheel, the axial driven wheel, the steering wheel, and the steering stationary wheel are all bevel gears.
[0021] By adopting the above technical solutions, the design of the bevel gears makes the power transmission of the transmission gear train smoother and more efficient in multiple axial directions, reduces power loss, and improves the operational stability and accuracy of the entire dual-axis tourbillon structure.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By setting four adjustment columns on the surface of the balance wheel and fitting C-shaped weights, the moment of inertia can be flexibly adjusted, thereby improving the adaptability and stability of the dual-axis tourbillon structure in different wearing environments;
[0024] 2. The outer tourbillon and the inner tourbillon are rotatably connected to the frame and the outer tourbillon via the first direction axis and the second direction axis, respectively, ensuring precise linkage between the inner and outer tourbillons and further improving the time accuracy and reliability of the entire system;
[0025] 3. The design of the transmission gear train allows the outer tourbillon to rotate around the first direction axis while the inner tourbillon rotates around the second direction axis, driving the escapement wheel to rotate. This multi-layered power transmission mechanism effectively reduces the impact of gravity on the movement and enhances the overall anti-interference capability. Attached Figure Description

Detailed Implementation
[0032] The present application will be further described in detail below with reference to Figures 1-5.
[0033] This application discloses a dual-axis gyroscope structure with adjustable moment of inertia.
[0034] As shown in Figures 1-3, the dual-axis tourbillon structure with adjustable moment of inertia includes a frame, a first direction axis, an outer tourbillon 2, a second direction axis 3, an inner tourbillon 4, an escapement mechanism, and a gear train. The outer tourbillon 2 is rotatably connected to the frame via the first direction axis, and the axis of the outer tourbillon 2 is perpendicular to the first direction axis. The inner tourbillon 4 is rotatably connected to the outer tourbillon 2 via the second direction axis 3, and the axes of the outer tourbillon 2, the inner tourbillon 4, and the second direction axis 3 are collinear. The escapement mechanism is located on the inner tourbillon 4. The escapement mechanism includes an escape wheel 22, an escape fork 23, and a balance wheel 24. Four adjusting posts 5 are evenly spaced around the circumference of the balance wheel 24. C-shaped weights 6 are fitted around the adjusting posts 5. The C-shaped weights 6 are interference-fitted with the adjusting posts 5. The gear train is used to drive the outer tourbillon 2 to rotate around the first direction axis, while simultaneously driving the inner tourbillon 4 to rotate around the second direction axis 3 and driving the escape wheel 22 to rotate.
[0035] The dual-axis tourbillon structure provided in this embodiment achieves bidirectional rotational motion, significantly improving the timekeeping accuracy and stability of the mechanical watch. The outer tourbillon 2 and inner tourbillon 4 rotate around axes in two different directions, allowing the entire system to counteract the effects of gravity in multiple dimensions. Simultaneously, the balance wheel 24 in the escapement mechanism is equipped with four adjusting pins 5 and C-shaped weights 6. By adjusting the angle of the C-shaped weights 6, the system's moment of inertia can be changed, thereby achieving precise time control. The design of the transmission gear train ensures coordinated movement between the outer tourbillon 2, inner tourbillon 4, and escape wheel 22, further enhancing the system's stability and reliability.
[0036] As shown in Figures 1-3, the transmission gear train specifically includes a driving gear 7, an axial driving gear 8, an axial driven gear 9, a circumferential driving gear 10, a circumferential driven gear 11, a steering gear 12, a steering synchronizing gear 1201, a steering stationary gear 13, a sun gear 14, and an escapement input gear 15. The axial driving gear 8, axial driven gear 9, steering gear 12, and steering stationary gear 13 are all bevel gears.
[0037] As shown in Figures 1-3, the first directional axis includes a moving side shaft 101 and a stationary side shaft 102 arranged collinearly. The moving side shaft 101 receives power, and the stationary side shaft 102 provides support. The clamping plate is provided with a moving side stationary shaft bracket 16 and a stationary side stationary shaft bracket 17. The moving side shaft 101 and the stationary side shaft 102 are rotatably connected to the moving side stationary shaft bracket 16 and the stationary side stationary shaft bracket 17 respectively through a moving side jewel bearing 18 and a stationary side jewel bearing 19. A moving side moving shaft bracket 20 is fixedly connected to the moving side shaft 101, and a stationary side moving shaft bracket 21 is fixedly connected to the stationary side shaft 102. Both the moving side moving shaft bracket 20 and the stationary side moving shaft bracket 21 are fixedly connected to the outer tourbillon 2. The axial source moving wheel 8 is rotatably connected to the frame plate around its own axis. The driving wheel 7 is coaxially arranged with the axial source moving wheel 8 and can rotate synchronously. The axial driven wheel 9 is coaxially arranged with the moving side shaft 101 and can rotate synchronously. The axial driving wheel 7 and the axial driven wheel 9 mesh with each other.
[0038] The stationary shaft 102 serves as a support component, rotatably connected to the stationary shaft bracket 17 via the stationary jewel bearing 19, ensuring the stability of the moving shaft 101 during rotation. The stationary moving shaft bracket 21, externally fixed to the stationary shaft 102, is also fixedly connected to the outer tourbillon 2, further enhancing the stability of the outer tourbillon 2. Throughout the transmission process, the application of the moving side jewel bearing 18 and the stationary side jewel bearing 19 reduces frictional losses, improves transmission efficiency, and extends service life.
[0039] As shown in Figure 4, the separate design of the moving side shaft 101 and the stationary side shaft 102 facilitates the grinding of the shaft surface, improves the surface finish of the shaft, and thus further enhances the stability and reliability of the transmission.
[0040] As shown in Figures 1-3 and 5, the second direction axis 3 is rotatably connected to the outer gyroscope 2 around its own axis. One end of the second direction axis 3 is integrally formed with a planetary carrier 301, and the other end is fixedly connected with a circumferential driving wheel 10. The planetary carrier 301 is fixedly connected to the inner gyroscope 4. To provide better support, an outer support plate 201 can be provided on the side of the circumferential driving wheel 10 away from the outer gyroscope 2. The outer support plate 201 is fixedly connected to the outer gyroscope 2. The circumferential driving wheel 10, the circumferential driven wheel 11, and the steering wheel 12 can all rotate around their own axes and are rotatably connected to the outer gyroscope 2 and the outer support plate 201. The steering synchronous wheel 1201 is coaxially connected to the steering wheel 12 and can rotate synchronously with the steering wheel 12. The circumferential driven wheel 11 meshes with both the steering synchronous wheel 1201 and the circumferential driving wheel 10. The axes of the three circumferential driving wheels 10, circumferential driven wheel 11, and steering wheel 12 are parallel to each other. The steering stationary wheel 13 is fixedly connected to the stationary side stationary shaft frame 17 and is coaxially arranged with the first direction axis. The steering stationary wheel 13 meshes with the steering wheel 12.
[0041] As shown in Figures 1-3, the escapement mechanism also includes an escapement frame 25. The escape wheel 22, escape fork 23, and balance wheel 24 are all mounted on the escapement frame 25, which is fixedly connected to the inner tourbillon 4. The sun gear 14 is fixedly mounted on the outer tourbillon 2 near the first direction axis. The sun gear 14 is coaxially mounted with the second direction axis 3 and rotatably connected to the second direction axis 3 via a central jewel bearing 26. The escape wheel 22 is coaxially fixedly connected to the escape input wheel 15, which meshes with the sun gear 14. The escapement mechanism is a commonly used technique in this field; therefore, the cooperation relationship between the escape wheel 22, escape fork 23, balance wheel 24, and escapement frame 25 will not be described in detail here.
[0042] The implementation principle of the dual-axis tourbillon structure with adjustable moment of inertia in this application embodiment is as follows:
[0043] The driving wheel 7 and the axial source driving wheel 8 are coaxially arranged and can rotate synchronously. When the driving wheel 7 receives power, the power is transmitted to the axial source driving wheel 8, causing the axial source driving wheel 8 to start rotating around its own axis. When the axial source driving wheel 8 rotates, it transmits power to the axial driven wheel 9 through a meshing relationship. Since the axial driven wheel 9 is coaxially arranged and can rotate synchronously with the moving side shaft 101, the rotation of the axial driven wheel 9 drives the moving side shaft 101 to rotate together. When the moving side shaft 101 rotates, the moving side shaft bracket 20 fixedly connected to it also rotates. Since the moving side shaft bracket 20 is fixedly connected to the outer gyroscope 2, the rotation of the moving side shaft bracket 20 will drive the outer gyroscope 2 to rotate around the first direction axis.
[0044] When the outer tourbillon 2 rotates around the first direction axis, the steering wheel 12, through its rotational connection with the outer tourbillon 2, can revolve around the first direction axis along with the outer tourbillon 2. The steering wheel 13, being fixedly connected to the stationary shaft bracket 17 and coaxial with the first direction axis, is stationary relative to the outer tourbillon 2 and the steering wheel 12; its position does not change with the rotation of the outer tourbillon 2. Therefore, when the steering wheel 12 revolves around the outer tourbillon 2, the steering wheel 12 and the steering wheel 13 achieve transmission through meshing; that is, the steering wheel 13 drives the steering wheel 12 to rotate around its own axis. After the steering wheel 12 begins to rotate around its axis, the steering synchronizing wheel 1201, being coaxially connected to and able to rotate synchronously with the steering wheel 12, and meshed with the circumferential driven wheel 11, also rotates. The circumferential driven wheel 11 simultaneously meshes with the circumferential source wheel 10, which is fixedly connected to the end of the second direction axis 3 furthest from the planet carrier 301. Therefore, the circumferential source wheel 10 and the second direction axis 3 also rotate along with the circumferential driven wheel 11. Simultaneously, the rotation of the second direction axis 3 will cause the planet carrier 301 and the inner gyrfly 4 to rotate together around the second direction axis 3.
[0045] Since the sun gear 14 is fixed on the side of the outer tourbillon 2 near the first direction axis and coaxially arranged with the second direction axis 3 and rotatably connected to the second direction axis 3 through the central jewel bearing 26, the sun gear 14 is stationary relative to the inner tourbillon 4, meaning its position does not change with the rotation of the inner tourbillon 4. The escape wheel 22 is located on the escapement frame 25, which is fixedly connected to the inner tourbillon 4. The escape wheel 22 is coaxially fixedly connected to the escape input wheel 15. Therefore, when the inner tourbillon 4 rotates, both the escape wheel 22 and the escape input wheel 15 will revolve around the sun gear 14, which is coaxially arranged with the second direction axis 3. The escape input wheel 15 meshes with the sun gear 14, so when the escape input wheel 15 revolves around the sun gear 14, it will also rotate around its own axis under the meshing action, thereby driving the escape wheel 22 to rotate together. When the escape wheel 22 rotates, it drives the escape mechanism, including the escape fork 23 and the balance wheel 24, to start working.
[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
