    Field of the invention
    The present invention relates to a type of mechanical wristwatch with a tourbillon, in particular to a movement with a transmission mechanism with a tourbillon inclined to the dial surface.
    State of the art
    There is currently on the market a type of a mechanical wristwatch with the inclination of the tourbillon, wherein the axis of rotation of the tourbillon support structure is to the dial surface. The specialty of the said tourbillon watches is that in the transmission chain from the drive wheel to the balance a certain part of the linear movement is changed in such a way that the movement has a certain angle, whereby the bevel gear is normally selected to implement the angle change. The advantage of this type of inclined tourbillon watch is that regardless of whether the watch is oriented horizontally or vertically, the balance wheel has an angle of less than 90 degrees to the horizontal plane, so that the frictional loss of the movement in the horizontal plane is close to that is in the vertical plane. This reduces the sensitivity of the watch to its position and increases the accuracy of the watch's running.
    WO Patent Publication No. 03/017009 A2 and WO Patent Patent Publication No. 2005/043257 A1 disclose a type of mechanical wristwatch with an inclined tourbillon, the tourbillon with AB having two axes of rotation that cross over form an angle, the driving force transmits power to the tourbillon mechanism through a bevel gear, namely a second wheel gear and a second wheel pinion, whereby the tourbillon rotates about the B axis as well as rotates about the A axis. By driving the two axes of rotation, the multi-angular trajectory of the revolution is driven forward, whereby this structure theoretically compensates for the isochronous error caused by gravity. However, there is the following deficiency: The cone shell formed by the axis of the balance wheel requires a very large volume, and due to the properties inherent in the bevel gear, the demands on the use of the fourth gear as a bevel gear are very high in terms of the required accuracy of machining and assembly , with movement operation affecting evenness.
    EP patent specification No. 1564 608 A2 discloses an inclined tourbillon structure, similar to WO 03/017009 A2, in which said structure a pair of bevel gears are set, this structure being positioned on the fourth gear and the escape gear shaft In addition to the lack of large space requirements, the sensitivity will be even higher in the case of manufacturing design errors.
    CN Patent Publication No. 101606108A and WO Patent Publication No. 2012/062659 A1 disclosed a type of clockwork with a tilted balance wheel, which, due to the small size of its pendulum axis, has to be implemented as a bevel gear mesh on each of its links to the main drive chain. The problem with this is that while skewing the balance can improve the movement's errors in different positions, there are still shortcomings in balancing gravity on the same horizontal plane. In addition, the difficulty in testing and processing inclined surfaces with grooves and holes is relatively high, making it difficult to ensure the positioning and concentricity of the bearing bracket, which can easily lead to negative effects on the evenness of the transmission system.
    Object of the invention
    The problem to be solved by the present invention is to overcome the weaknesses of conventional technology, for this purpose a clockwork is provided with a transmission mechanism with an inclined tourbillon to the dial surface, the construction of which is simple, the manufacturability good and practical for further processing.

    On said third wheel bearing bracket, the third wheel assembly and a precious stone (bearing) of the upper axis pivot point of the fourth wheel assembly are mounted, the fourth wheel gear carrying the fifth wheel assembly and the fourth wheel pinion , wherein the tourbillon assembly with the fourth wheel pinion forms a single body by pressure.
    The said intermediate gear arrangement comprises a first intermediate gear, which is pressed by pressure to form a unitary body, an intermediate gear and a second intermediate gear, said second intermediate gear meshing with the barrel, the third wheel Assembly includes a third wheel-pinion and a third wheel-pinion pressed into a unitary body, said third wheel-pinion and the small second idler-pinion forming a pair of bevel gears which mesh with each other and change the direction of the transmission chain; and the fourth wheel assembly includes a fourth wheel pinion and a fourth wheel pinion pressed into a unitary body, the third wheel pinion and the fourth wheel pinion meshing with one another; wherein the fifth wheel arrangement comprises a fifth wheel gear pressed into a unitary body and the fifth wheel pinion, wherein the fourth wheel gear and the fifth wheel pinion mesh with one another.
    Said barrel meshes with the central wheel gear, the central wheel gear having a concentric friction fit with a drive pinion, the minute wheel arrangement comprising a minute wheel gear and a minute wheel pinion pressed into a unitary body, which said minute wheel and minute wheel gear mesh, and wherein the minute wheel pinion and hour wheel mesh; and wherein the minute hand is arranged on the upper end part of the drive pinion and the hour hand is arranged on the upper end part of the hour wheel.
    On said inclined surface with a kink, two holes standing vertically to the inclined surface with a kink are formed, with threaded feet being applied to the holes for placement.

    Said fourth wheel gear is fixed by a screw to the middle bearing bracket, the second wheel gear receiving the fifth wheel pinion and the precious stone (bearing) of the upper axis pivot point of the second wheel pinion.
    The advantageous effects are: Because the bevel gear is positioned in the second stage, which has a relatively low speed, the main drive chain, the influence of the bevel gear is reduced in terms of the evenness of the mechanical transmission, which also reduces the sensitivity of the Bevel gear is reduced in terms of further processing and assembly. Only on the small bearing bridge is an inclined surface with a kink and nail holes positioned at an angle. All the individual parts are quite small, which is useful for manufacturing and testing.
