    Description TECHNICAL FIELD The present invention relates to a three-axis tourbillon mechanism for a mechanical wristwatch. Background Art The constructive feature of a tourbillon is that the armature escapement, as a main speed control component, rotates by driving the frame of the tourbillon to compensate for the influence of gravity. A biaxial tourbillon is known from the patent CN 102 809 919 A, the structure of which is characterized in that the rotating axis of the inner-axis frame relative to the rotating axis of the Aus-senachsen-frame is arranged vertically, wherein the rotating axis of the outer frame perpendicular to the axis of the mechanism stands. The tourbillon with an inner axle, equipped with an anchor escapement for speed control, which is driven by an outer axle frame, rotates together around the outer axle and also rotates about the inner axle, whereby the anchor and the balance spring receive a complicated trajectory, the Complex compared to a single-axis tourbillon. Their biggest advantage is that the more complicated the armature escapement is for speed control, the more obvious is the ability to balance gravity, which ultimately improves the accuracy of the mechanical wristwatch with a multi-axis tourbillon, but the two-axis tourbillon itself moved three-dimensional cylindrical and the path of the anchor escapement for speed regulation changes only in a limited three-dimensional space.
    In order to better balance the influence of Earth's gravity, a three-axis tourbillon mechanism was developed, to which a third axis of rotation was added based on the structure of a two-axle tourbillon. This causes the toe of the tourbillon to become nearly spherical so that the armature escapement for speed regulation within the tourbillon can move in either direction to improve the ability to overcome the earth's gravity. But this known structure of the three-axle tourbillon has the following disadvantages: first, that the third axis is supported from above and below. Such a structure takes up more axial space, so that the thickness of the wristwatch is considerably increased, which is not pleasant to wear for the user. Second, when the third axle is supported by a ball bearing. Special thin ball bearings used in small wristwatches can not achieve the desired function by downsizing normal ball bearings. By contrast, the ball bearing in the tourbillon mechanism is designed to accommodate the high speed rotation of the tourbillon. For this reason, the wear of the ball bearing is an unavoidable disadvantage. The manufacturing difficulties and the costs for a wear-resistant and high-precision ball bearing are very high.
    Summary of the Invention The present invention seeks to overcome the technical problems presented by providing a three-axis tourbillon mechanism that is simple in construction and has good technology but is easy to manufacture.
    The invention relates to a three-axis tourbillon mechanism for a mechanical wristwatch comprising an inner axle tourbillon fixed to a drive wheel and an outer axle frame and a differential mechanism. The drive wheel is meshed with the drive-receiving wheel and the axis of rotation of the inner-axis tourbillon is perpendicular to the axis of rotation of the outer-axle frame, with the intermediate gear meshing with the secondary-directional pinion sprocket mounted in the inner-axle tourbillon. The differential mechanism includes a planetary mechanism as the third rotation axis with a lower support.
    The differential mechanism comprises a carrier, a planetary gear, a gear shaft and a second clamping plate column. The planet gear is riveted together with the gear shaft. The gear shaft is located on the precious stone bearing of the carrier and the planetary gear is meshed with the three-axis planetary mechanism. The clamping plate is secured to the clamping plate by the second clamping plate post.
    The three-axis planetary mechanism comprises a first clamping plate post, a bearing carrier, a cylindrical-shaped roller bearing, a cylindrical roller, an inner ring and a sun gear. The planet gear is meshed with the sun gear whose gear ratio is 1: 5 to 1:15. The drive wheel is fastened together with the bearing bracket by the first clamping plate shoulder, and the roller is mounted flat on the cylindrical roller bearing and the cylindrical roller bearing is fastened together with the bearing bracket. The role can rotate freely. The sun gear is integrated in the coaxial inner ring with the lower end of the cylindrical roller contacting the lower end portion of the inner ring and the outer edge. The upper end of the cylindrical roller is adapted to the gap of the inner edge land, so that the bearing support is free to rotate about the axis of the inner ring and the inner ring is fastened to the clamping plate by screws and the inner axis tourbillon and the outer axis frame rotate the axis of the sun gear.
    The planetary gear and the sun gear is a bevel gear. The planetary gear rotates around the sun gear while the planetary gear rotates about the axis of the outer axle frame.
    The planet gear is a spur gear and the sun gear is a face gear. The planetary gear rotates about the sun gear while the outside of the planetary gear also rotates about the axis of rotation of the outer axle frame.
    The cylindrical roll consists of three, five, seven or nine pieces. The cylindrical roller bearing and the bearing bracket are bolted or directly pressed together.
    An advantageous effect of this invention is that the bottom-supported planetary mechanism as the third axis of rotation causes a technically feasible construction is achieved and especially the cylindrical roller bearing is easy to work, the processing costs for accessories are low and the invention for industrial Series production is suitable. The trajectory of the three-axis tourbillon mechanism transforms from cylindrical to spherical so that the inner armature escapement can rotate three-dimensionally at many angles, whose trajectory is more complicated and the effect of balancing gravity is greatly improved, thus making the mechanical wristwatch more accurate Time can show.

    DETAILED DESCRIPTION OF THE DRAWINGS The invention will be described in more detail below with reference to the figures and exemplary embodiments.
    As shown in Fig. 1, the invention three-axis tourbillon mechanism for a mechanical wristwatch from the patent CN 102 809 919 A is known, this invention based on "two-axis tourbillon for a mechanical wristwatch" was further developed. On the construction of the two-axle tourbillon is not discussed here again.
    Embodiment 1: The construction of the inventive three-axis tourbillon mechanism for a mechanical wristwatch comprises an inner axle tourbillon 14 fixed to the drive wheel 1, an outer axle frame 13 and a differential mechanism. The drive wheel 1 is toothed with a wheel for drive receiving 15. The axis of rotation of the inner-axis tourbillon 14 is perpendicular to the axis of rotation of the outer-axis frame 13. Per minute, the inner-axis tourbillon 14 rotates around a circle. The outer axle frame 13 runs around a circle every 12.5 minutes. The idler gear 16 is meshed with the sprocket mounted on the inner axle tourbillon 14 for a seconds indicator 17. The differential mechanism includes a planetary mechanism for a third axle / triaxial planetary mechanism supported from below.
    The differential mechanism comprises a Träger2, a planetary gear 3, a transmission shaft 4, a planetary mechanism, a clamping plate 10 and a second Klemmplattensâule 11. The planetary gear 3 is riveted together with the transmission shaft 4. The planetary gear 3 is a bevel gear and the gear shaft 4 is provided on the gemstone bearing of the carrier 2. The planetary gear 3 is meshed with the planetary mechanism. The clamping plate 10 is fastened to the clamping plate by the second clamping plate post 11.
    The planetary mechanism, which is supported from below, comprises a first Klemmplattensâule 5, a component of the zylinderformigen Rollentrâgers, an inner ring 9 and a sun gear 12, wherein the component of the zylinderformigen roller carrier from a Lagerträgers 6, a zylinderformigen roller bearing 7, a cylindrical roller 8 is. A designed as a bevel gear sun gear 12, wherein the planetary gear 3 is interlocked with the sun gear 12, the Übersetzungsver- ratio 1: 3.6. This means that every nine minutes the planetary mechanism goes through a circle. Optionally a value within 5-15 can be selected. The drive wheel 1 is fixed by the first Klemmplattensâule 5 with the Lagertragers 6. The cylindrical roller 8 is uniformly installed on the cylindrical roller bearing 7, whereby the cylindrical roller bearing 7 is connected to the bearing bracket 6 together. The cylindrical roller 8 is free to rotate. The number of cylindrical rollers 8 depends on the actual condition of the construction. The number must, however, have an odd number, e.g. 3, 5, 7, 9. The embodiment of the invention uses 5 cylindrical rollers. The sun gear 12 is coaxially fixed to the inner ring 9. The cylindrical roller 8 comes with the lower end with the outer edge web of the inner ring 9 into contact. The obéré end of the cylindrical roller 8 adapts to the inner edge land of the sun gear 12. It is important to ensure that equipped with five cylin-drical rollers 8 Lagererträgers 6 can rotate freely about the axis of the inner ring 9. The inner ring 9 is screwed together with the clamping plate 10. The inner axle tourbillon 14 is rotated with the outer axle frame 13 about the axis of the sun gear 12.
    Embodiment 2: The planetary gear 3 is a spur gear. The sun gear 12 is a face wheel. Both wheels interlock and form a vertically arranged gearbox. The cylindrical roller bearing 7 is pressed together with the bearing support 6. The other structures are the same as in Embodiment 1 and will not be explained further.
    The operation of the inventive embodiment 1 of a three-axis tourbillon mechanism for a mechanical wristwatch is explained below: The wheel for the drive mount 15 drives the drive wheel 1. Because the drive wheel 1 is fixed together with the bearing bracket 6 and is part of the cylindrical roller bearing support member, the inner ring 9 and the sun gear 12 form a cylindrical roller bearing. Because the planetary gear 3 meshes with the sun gear 12, the planetary gear 3 revolves around the sun gear 12 and at the same time rotates about the axis of rotation of the outer shaft Frame 13. The operation of the two-axle tourbillon is known from the patent CN 102 809 919 A "two-axle tourbillon for a mechanical wristwatch". By driving the third axis, the inner-axis tourbillon 14 rotates around a circle per minute and the outer-axis frame 13 runs around a circle every 2.5 minutes. The outer axle frame 13 takes about 2-10 minutes to go through a circle. The rotational speed of the third axis is 9 minutes per circle. This value is optionally within 5-15.
    The operation of the inventive embodiment of a three-axis tourbillon mechanism for a mechanical wristwatch is explained below: The wheel for the drive mount 15 drives the drive wheel 1. Because the drive wheel 1 is fastened together with the bearing support 6 and belongs to a component of the cylindrical roller bearing support. The inner ring 9 and the sun gear 12 form a cylindrical roller bearing. The arranged on the drive wheel 1 inner-axis tourbillon 14 rotates and rotates about the axis of the sun gear 12th
    Because the present invention uses the construction of the third rotation axis as a lower support, therefore, the wristwatch does not thicken when the accuracy of the wristwatch increases, the small and beautiful outer appearance is increased.
