Description

[0001] The present 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 Art

[0002] In the mechanical watch manufacturing industry, the tourbillon is a device that reduces isochronous errors. The characteristics of this device are that the balance spring system and the escapement are placed in the frame, and can rotate with the frame while running, which minimizes the position error of the clock caused by the earth's gravity and improves the travel accuracy. The traditional single-axis tourbillon has been developed for many years. However, with the advancement of technology and the diversification of consumer needs, the traditional single-axis tourbillon can no longer meet higher-level needs, especially in complex and changeable wearing environments, and a more advanced tourbillon structure is needed to further improve performance.

[0003] In order to meet this challenge, there is a related technology that adds a second rotating axis to the original single-axis tourbillon to form a dual-axis tourbillon structure to further offset the effects of gravity in different directions. However, although the dual-axis tourbillon in the related technology can further reduce the effects of gravity, it is still difficult to flexibly adjust the moment of inertia of the balance wheel in actual applications, resulting in limited ability to adapt to different environments. Summary of the invention

[0004] In order to flexibly adjust the moment of inertia of the balance wheel, the present application provides a dual-axis tourbillon structure with adjustable moment of inertia.

[0005] The present application provides a dual-axis tourbillon structure with adjustable moment of inertia, which adopts the following technical solution: A dual-axis tourbillon structure with adjustable moment of inertia, comprising a frame, a first direction axis, an outer tourbillon, a second direction axis, an inner tourbillon, an escapement mechanism and a transmission wheel system, wherein the outer tourbillon is rotationally 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 rotationally 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 arranged in a colinear manner, the escapement mechanism is arranged on the inner tourbillon, the escapement mechanism comprises an escapement wheel, an escapement fork and a hairspring balance wheel, the surface of the hairspring balance wheel is provided with four adjustment columns at equal intervals around the circumference of the hairspring balance wheel, the outer sleeve of the adjustment column is provided with a C-shaped weight, and the C-shaped weight is interference-fitted with the adjustment column, and the transmission wheel system is used for driving the outer tourbillon to rotate around the first direction axis while driving the inner tourbillon to rotate around the second direction axis and driving the escapement wheel to rotate at the same time.

[0006] By adopting the above technical solution, the dual-axis tourbillon structure realizes rotational movement in two directions, improving the accuracy and stability of the mechanical watch. The outer tourbillon and the inner tourbillon rotate around two axes in different directions, allowing the entire system to offset the influence of gravity in multiple directions. At the same time, four adjustment columns and C-type weights are set on the surface of the hairspring balance in the escapement mechanism. The moment of inertia of the system can be changed by adjusting the angle of the C-type weight, thereby achieving precise time control. The design of the transmission wheel system ensures the coordinated movement between the outer tourbillon, the inner tourbillon and the escapement wheel, further improving the stability and reliability of the system.

[0007] Optionally, the first direction axis includes a colinearly arranged moving side axis and a stationary side axis, the moving side axis is used to receive power, and the stationary side axis is used to provide support, the clamp 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, the moving side axis is fixedly connected to a moving side moving axis frame outside, the stationary side axis is fixedly connected to a stationary side moving axis frame outside, and the moving side moving axis frame and the stationary side moving axis frame are both fixedly connected to the external tourbillon.

[0008] By adopting the above technical solution, the split design of the moving side shaft and the static side shaft not only realizes the effective separation of power transmission and support functions, but also facilitates the grinding operation of the shaft surface, thereby improving the smoothness of the shaft surface. The application of the moving side jewel bearing and the static side jewel bearing further reduces friction loss and prolongs the service life. In addition, the design of the moving side shaft frame and the static side shaft frame ensures the stable connection of the outer tourbillon and enhances the rigidity and anti-seismic performance of the overall structure.

[0009] Optionally, the transmission wheel system includes an axial transmission system for driving the outer tourbillon 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 can be rotatably connected to the frame plate around its own axis, the driving wheel is coaxially arranged with the axial source driving wheel and can rotate synchronously, the axial driven wheel is coaxially arranged with the moving side shaft and can rotate synchronously, and the axial driving wheel is meshed with the axial driven wheel.

[0010] 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, the power is transmitted to the axial source driving wheel, so that the axial source driving wheel starts to rotate around its own axis. When the axial source driving wheel rotates, the power is transmitted to the axial driven wheel through the 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, the moving side moving shaft frame fixedly connected to it also rotates accordingly. Since the moving side moving shaft frame is fixedly connected to the outer tourbillon, the rotation of the moving side moving shaft frame will drive the outer tourbillon to rotate around the first direction axis. At the same time, the static side shaft, as a supporting part, is rotatably connected to the static side static shaft frame through the static side jewel bearing, ensuring the stability of the dynamic side shaft during the rotation process. The static side moving shaft frame fixedly connected to the static side shaft is also fixedly connected to the outer tourbillon, further enhancing the stability of the outer tourbillon. In the entire transmission process, the application of the moving side jewel bearing and the static side jewel bearing reduces friction loss, improves transmission efficiency, and prolongs service life. The split design of the moving side shaft and the static side shaft facilitates the shaft surface grinding operation, improves the shaft surface finish, and further enhances the stability and reliability of the transmission.

[0011] Optionally, the second direction shaft is rotatably connected to the outer tourbillon so as to rotate around its own axis, a planet carrier is integrally formed at one end of the second direction shaft, and the other end is used to receive power, and the planet carrier is fixedly connected to the inner tourbillon.

[0012] By adopting the above technical solution, the second direction axis can be rotatably connected to the outer tourbillon around its own axis, so that the inner tourbillon can stably rotate around the second direction axis. The planet carrier integrally formed at one end of the second direction axis is fixedly connected to the inner tourbillon, ensuring the reliable linkage between the inner tourbillon and the second direction axis, and improving the mechanical accuracy and stability of the entire system. The design of receiving power at the other end ensures the effective transmission of power, so that the inner and outer tourbillons can work together to achieve a more complex movement mode.

[0013] Optionally, the transmission wheel system includes a circumferential transmission system for driving the inner tourbillon to rotate around the second direction axis, the circumferential transmission system includes a circumferential source driving wheel, a circumferential driven wheel, a steering synchronous wheel, a steering driven wheel and a steering static wheel, the circumferential source driving wheel is fixedly connected to the end of the second direction axis away from the planetary frame, the circumferential driven wheel and the steering driven wheel can both be rotatably connected to the outer tourbillon around their own axes, the steering synchronous wheel is coaxially connected to the steering driven wheel and can rotate synchronously with the steering driven wheel, the circumferential driven wheel is meshed with the steering synchronous wheel and the circumferential source driving wheel at the same time, the axes of the circumferential source driving wheel, the circumferential driven wheel and the steering driven wheel are parallel to each other, the steering static wheel is fixedly connected to the static side static axis frame and is coaxially arranged with the first direction axis, and the steering static wheel is meshed with the steering driving wheel.

[0014] By adopting the above technical solution, the steering wheel can revolve around the first direction axis along with the outer tourbillon through its rotational connection with the outer tourbillon as the outer tourbillon rotates around the first direction axis. As the steering stationary wheel is fixedly connected to the stationary shaft frame on the stationary side and is coaxially arranged with the first direction axis, the steering stationary wheel is stationary relative to the outer tourbillon and the steering wheel, that is, its position does not change with the rotation of the outer tourbillon. Therefore, when the steering wheel revolves along with the rotation of the outer tourbillon, the steering wheel and the steering stationary wheel will realize transmission through a meshing relationship, that is, the steering stationary wheel will drive the steering wheel to rotate around its own axis direction. After the steering wheel starts to rotate around its axis, since the steering synchronous wheel is coaxially connected with the steering wheel and can rotate synchronously with the steering wheel, and since the steering synchronous wheel is meshed with the circumferential driven wheel, the circumferential driven wheel also rotates accordingly. The circumferential driven wheel is meshed with the circumferential source driven wheel at the same time, and the circumferential source driven wheel is fixedly connected to the end of the second direction axis away from the planet carrier, so the circumferential source driven wheel and the second direction axis also rotate with the rotation of the circumferential driven wheel. At the same time, the rotation of the second direction axis will drive the planet carrier and the inner tourbillon to rotate around the second direction axis. The planet carrier is fixedly connected to the inner tourbillon, ensuring the reliable linkage between the inner tourbillon and the second direction axis.

[0015] Optionally, the escapement mechanism further comprises an escapement frame, the escapement wheel, the escapement fork and the hairspring balance wheel are all arranged on the escapement frame, and the escapement frame is fixedly connected to the inner tourbillon.

[0016] By adopting the above technical solution, the escapement wheel, the pallet fork and the balance wheel with hairspring are connected to the escapement frame, so that these components can operate stably under the constraints of the escapement frame. At the same time, the escapement frame is fixedly connected to the inner tourbillon, ensuring that the escapement mechanism can move with the inner tourbillon, realizing the precise time adjustment function.

[0017] Optionally, the transmission wheel system includes an escapement transmission system for driving the escapement wheel to rotate, the escapement transmission system includes a sun wheel and an escapement input wheel, the sun wheel is fixedly arranged on a side of the outer tourbillon close to the first direction axis, the sun wheel is coaxially arranged with the second direction axis and is rotatably connected to the second direction axis through a center jewel bearing, the escapement wheel is coaxially fixedly connected with the escapement input wheel, and the escapement input wheel is meshed with the sun wheel.

[0018] By adopting the above technical solution, when the circumferential source driving wheel receives power and starts to rotate, it will drive the second direction axis to rotate together. Since the planet carrier is integrally formed with the second direction axis and fixedly connected to the inner tourbillon, the inner tourbillon will also rotate with the rotation of the second direction axis. The escapement transmission system includes a sun wheel and an escapement input wheel. The sun wheel is fixedly arranged on the side of the outer tourbillon close to the first direction axis and is coaxially arranged with the second direction axis and is rotatably connected with the second direction axis through a central jewel bearing, so the sun wheel is stationary relative to the inner tourbillon, that is, its position does not change with the rotation of the inner tourbillon. The escapement wheel is arranged on the escapement frame, and the escapement frame is fixedly connected to the inner tourbillon, and the escapement input wheel is coaxially fixedly connected to the escapement wheel. Therefore, when the inner tourbillon rotates, the escapement wheel and the escapement input wheel will both revolve around the sun wheel coaxially arranged with the second direction axis, and the escapement input wheel meshes with the sun wheel. Therefore, when the escapement input wheel revolves around the sun wheel, it will also rotate around its own axis direction under the meshing action, thereby driving the escapement wheel to rotate together. When the escape wheel rotates, it drives the escapement mechanism including the pallet fork and the balance wheel to start working.

[0019] Optionally, the axial source driving wheel, the axial driven wheel, the steering driving wheel and the steering static wheel are all bevel gears.

[0020] By adopting the above technical solution, the design of the bevel gear makes the power transmission of the transmission gear train in multiple axis directions smoother and more efficient, reduces power loss, and improves the operating stability and accuracy of the entire dual-axis tourbillon structure.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting four adjustment columns on the surface of the balance wheel and installing 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; 2. The outer tourbillon and the inner tourbillon are rotatably connected to the frame and the outer tourbillon through the first direction axis and the second direction axis respectively, ensuring the precise linkage between the inner and outer tourbillons, further improving the time accuracy and reliability of the entire system; 3. The design of the transmission wheel system allows the outer tourbillon to rotate around the first axis while the inner tourbillon can rotate around the second axis and drive the escapement wheel to rotate. This multi-level power transmission mechanism effectively reduces the impact of gravity on the movement and enhances the overall anti-interference ability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-5 This application is described in further detail.

The outer tourbillon 2 is rotatably connected to the frame through 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 through the second direction axis 3, and the axes of the outer tourbillon 2, the inner tourbillon 4 and the second direction axis 3 are all arranged in a colinear line. The escapement mechanism is arranged on the inner tourbillon 4, and the escapement mechanism includes an escapement wheel 22, an escapement fork 23 and a hairspring balance wheel 24. Four adjustment columns 5 are arranged at equal intervals on the surface of the hairspring balance wheel 24 around the circumference of the hairspring balance wheel 24. The outer sleeve of the adjustment column 5 is provided with a C-type weight 6, and the C-type weight 6 is interference fit with the adjustment column 5. The transmission wheel system is used for driving the outer tourbillon 2 to rotate around the first direction axis while driving the inner tourbillon 4 to rotate around the second direction axis 3 and driving the escapement wheel 22 to rotate at the same time.

[0031] The dual-axis tourbillon structure provided in the embodiment of the present application realizes bidirectional rotational motion, significantly improving the travel accuracy and stability of the mechanical watch. The outer tourbillon 2 and the inner tourbillon 4 rotate around two axes in different directions respectively, so that the entire system can offset the gravity effect in multiple dimensions. At the same time, four adjustment columns 5 and C-type weights 6 are configured on the surface of the hairspring balance wheel 24 in the escapement mechanism. By adjusting the angle of the C-type weight 6, the rotational inertia of the system can be changed, thereby achieving precise time control. The design of the transmission wheel system ensures the coordinated movement between the outer tourbillon 2, the inner tourbillon 4 and the escapement wheel 22, further enhancing the stability and reliability of the system.

[0032] like Figure 1-Figure 3 As shown, specifically, the transmission wheel system includes a driving wheel 7, an axial source driving wheel 8, an axial driven wheel 9, a circumferential source driving wheel 10, a circumferential driven wheel 11, a steering driving wheel 12, a steering synchronous wheel 1201, a steering static wheel 13, a sun wheel 14 and an escapement input wheel 15. The axial source driving wheel 8, the axial driven wheel 9, the steering driving wheel 12 and the steering static wheel 13 are all bevel gears.

[0033] like Figure 1-Figure 3As shown, the first direction axis includes a colinear moving side axis 101 and a static side axis 102, the moving side axis 101 is used to receive power, and the static side axis 102 is used to provide support, a moving side static axis frame 16 and a static side static axis frame 17 are provided on the clamping plate, the moving side axis 101 and the static side axis 102 are rotatably connected to the moving side static axis frame 16 and the static side static axis frame 17 through the moving side jewel bearing 18 and the static side jewel bearing 19 respectively, the moving side axis 101 is externally fixedly connected to the moving side moving axis frame 20, and the static side axis 102 is externally fixedly connected to the static side moving axis frame 21, and the moving side moving axis frame 20 and the static side moving axis frame 21 are both fixedly connected to the outer tourbillon 2. The axial source driving wheel 8 can be rotatably connected to the frame plate around its own axis, the driving wheel 7 is coaxially arranged with the axial source driving wheel 8 and can rotate synchronously, the axial driven wheel 9 is coaxially arranged with the moving side axis 101 and can rotate synchronously, and the axial driving wheel 7 is meshed with the axial driven wheel 9.

[0034] The stationary shaft 102 is used as a supporting part, and is rotatably connected to the stationary shaft frame 17 through the stationary jewel bearing 19, ensuring the stability of the moving shaft 101 during the rotation process. The stationary moving shaft frame 21 fixedly connected to the stationary shaft 102 is also fixedly connected to the outer tourbillon 2, further enhancing the stability of the outer tourbillon 2. In the entire transmission process, the use of the moving side jewel bearing 18 and the stationary side jewel bearing 19 reduces friction loss, improves transmission efficiency, and prolongs service life.

[0035] like Figure 4 As shown, the split design of the moving side shaft 101 and the stationary side shaft 102 facilitates the shaft surface grinding operation, improves the shaft surface finish, and further enhances the stability and reliability of the transmission.

[0036] like Figure 1-Figure 3 and Figure 5 As shown, the second direction shaft 3 can be rotatably connected to the outer tourbillon 2 around its own axis, one end of the second direction shaft 3 is integrally formed with a planet carrier 301, and the other end is fixedly connected to a circumferential source driving wheel 10, and the planet carrier 301 is fixedly connected to the inner tourbillon 4. In order to provide better support, an outer support plate 201 can be provided on the side of the circumferential source driving wheel 10 away from the outer tourbillon 2. The outer support plate 201 is fixedly connected to the outer tourbillon 2. The circumferential source driving wheel 10, the circumferential driven wheel 11 and the steering driven wheel 12 can all be rotatably connected to the outer tourbillon 2 and the outer support plate 201 around their own axes. The steering synchronous wheel 1201 is coaxially connected to the steering driven wheel 12 and can rotate synchronously with the steering driven wheel 12. The circumferential driven wheel 11 is meshed with the steering synchronous wheel 1201 and the circumferential source driving wheel 10 at the same time. The axes of the circumferential source driving wheel 10, the circumferential driven wheel 11 and the steering driven wheel 12 are parallel to each other. The steering static wheel 13 is fixedly connected to the static side static shaft frame 17 and is coaxially arranged with the first direction axis. The steering static wheel 13 is meshed with the steering driven wheel 12.

[0037] like Figure 1-Figure 3 As shown, the escapement mechanism also includes an escapement frame 25, and the escapement wheel 22, the escapement fork 23 and the hairspring balance wheel 24 are all arranged on the escapement frame 25, and the escapement frame 25 is fixedly connected to the inner tourbillon 4. The sun wheel 14 is fixedly arranged on the side of the outer tourbillon 2 close to the first direction axis. The sun wheel 14 is coaxially arranged with the second direction axis 3 and is rotatably connected with the second direction axis 3 through the central jewel bearing 26. The escapement wheel 22 is coaxially fixedly connected with the escapement input wheel 15, and the escapement input wheel 15 is meshed with the sun wheel 14. The escapement mechanism is a commonly used technical means in this field, so the matching relationship between the escapement wheel 22, the escapement fork 23, the hairspring balance wheel 24 and the escapement frame 25 will not be described in detail here.

[0038] The implementation principle of a dual-axis tourbillon structure with adjustable moment of inertia in the embodiment of the present application is: The driving wheel 7 is coaxially arranged with the axial source driving wheel 8 and can rotate synchronously. When the driving wheel 7 receives power, the power is transmitted to the axial source driving wheel 8, so that the axial source driving wheel 8 starts to rotate around its own axis. When the axial source driving wheel 8 rotates, the power is transmitted to the axial driven wheel 9 through the meshing relationship. Since the axial driven wheel 9 is coaxially arranged with the moving side shaft 101 and can rotate synchronously, 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 moving shaft frame 20 fixedly connected to it also rotates accordingly. Since the moving side moving shaft frame 20 is fixedly connected to the outer tourbillon 2, the rotation of the moving side moving shaft frame 20 will drive the outer tourbillon 2 to rotate around the first direction axis.

[0039] When the outer tourbillon 2 rotates around the first direction axis, the steering wheel 12 can revolve around the first direction axis together with the outer tourbillon 2 through its rotational connection with the outer tourbillon 2 as the outer tourbillon 2 rotates around the first direction axis. As the steering stationary wheel 13 is fixedly connected to the stationary shaft frame 17 on the stationary side and is coaxially arranged with the first direction axis, the steering stationary wheel 13 is stationary relative to the outer tourbillon 2 and the steering wheel 12, that is, its position does not change with the rotation of the outer tourbillon 2. Therefore, when the steering wheel 12 revolves with the rotation of the outer tourbillon 2, the steering wheel 12 and the steering stationary wheel 13 will realize transmission through a meshing relationship, that is, the steering stationary wheel 13 will drive the steering wheel 12 to rotate around its own axis direction. After the steering driven wheel 12 starts to rotate around its axis, since the steering synchronous wheel 1201 is coaxially connected to the steering driven wheel 12 and can rotate synchronously with the steering driven wheel 12, and since the steering synchronous wheel 1201 is meshed with the circumferential driven wheel 11, the circumferential driven wheel 11 also rotates accordingly. The circumferential driven wheel 11 is also meshed with the circumferential source driven wheel 10, and the circumferential source driven wheel 10 is fixedly connected to the end of the second direction shaft 3 away from the planet carrier 301, so the circumferential source driven wheel 10 and the second direction shaft 3 also rotate with the rotation of the circumferential driven wheel 11. At the same time, the rotation of the second direction shaft 3 will drive the planet carrier 301 and the inner tourbillon 4 to rotate around the second direction shaft 3 together.

[0040] Since the sun wheel 14 is fixedly arranged on the side of the outer tourbillon 2 close to the first direction axis and is coaxially arranged with the second direction axis 3 and is rotatably connected with the second direction axis 3 through the central jewel bearing 26, the sun wheel 14 is stationary relative to the inner tourbillon 4, that is, its position does not change with the rotation of the inner tourbillon 4. The escapement wheel 22 is arranged on the escapement frame 25, and the escapement frame 25 is fixedly connected with the inner tourbillon 4, and the escapement wheel 22 is coaxially fixedly connected with the escapement input wheel 15. Therefore, when the inner tourbillon 4 rotates, the escapement wheel 22 and the escapement input wheel 15 will revolve around the sun wheel 14 coaxially arranged with the second direction axis 3, and the escapement input wheel 15 is meshed with the sun wheel 14. Therefore, when the escapement input wheel 15 revolves around the sun wheel 14, it will also rotate around its own axis direction under the meshing effect, thereby driving the escapement wheel 22 to rotate together. When the escapement wheel 22 rotates, it will drive the escapement mechanism including the escapement fork 23 and the hairspring balance wheel 24 to start working.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
