Description
Technical Field
The invention belongs to the technical field of mechanical clocks and watches, and relates to an oval sphere cage type double-shaft rotary escapement speed regulating mechanism and a clock.
Background
Two hundred years ago, mr Lu Yi Bao He invented a tourbillon mechanism of a clock speed regulating device, the principle of which is that a balance spring, a fork lever and an escapement system of a handle watch are designed to operate on the same shaft, and when the mechanism rotates continuously for 360 degrees, the azimuth errors of parts can be mutually offset, so that the errors are eliminated. The mechanism is precise, exquisite and accurate, so that the tourbillon surface enjoys the reputation of the owner.
The rotary escapement speed regulating mechanism watch is also called tourbillon watch. The tourbillon is designed in such a way that the escapement of the timepiece core is placed inside a frame, which makes a regular 360-degree rotation about the axis of the shaft, i.e. the balance. The escapement speed regulating mechanism of the common mechanical clock is fixed, so when the rest position of the watch is changed, the escapement speed regulating mechanism generates errors due to different stress of escapement parts due to the change of the position. The escapement speed regulating mechanism of the tourbillon watch is rotated continuously by 360 degrees, and the errors of the azimuth of the watch can be combined and offset, so that the errors are reduced to the greatest extent, and even eliminated. Currently, most tourbillons rotate one revolution in 1 minute, which is also an ideal rotation speed recognized in the industry.
Although the watches of the present day face more position changes, the ability of tourbillon to calibrate accuracy is reduced, tourbillon is still used as a top-level tabulation process and is tourbillon for most of the table fans loving mechanical tabulation.
The escapement speed regulating mechanism is a common speed regulating mechanism in mechanical clock mechanism and consists of two parts, namely an escapement mechanism and a speed regulating mechanism. The escapement includes an escape wheel component, an escape fork component; the speed regulating mechanism comprises a balance spring assembly. The speed regulating mechanism depends on the periodic oscillation of the balance spring to ensure that the escapement mechanism keeps accurate and regular continuous motion, thereby achieving the speed regulating function.
Fig. 1 shows a conventional escapement mechanism commonly used in a conventional mechanical timepiece. The working principle is as follows: the second wheel component 1 drives the escape wheel component 8, the escape wheel component 8 drives the escape fork component 9 to do reciprocating swing around the point a through a special gear, and the escape fork component 9 drives the balance spring component 11 to do regular oscillating swing through a fork b when swinging, so as to generate a timing source. The balance spring in the escapement speed regulating system of the common mechanical watch is influenced by tightness and metal fatigue, and the swinging rule of the balance wheel is also influenced by gravity, so that errors are easy to generate.
Fig. 2 shows a single-axis rotary escapement (commonly called a single-axis rotary tourbillon) commonly used in another mechanical timepiece of the prior art. The working principle is as follows: the three-wheel member 21 carries the second gear 10b, the second gear 10b and the rotary support 7 are rigidly connected, so that the rotary support 7 and the second gear 10b rotate synchronously, since the fixed second wheel plate 10 is mounted and fixed on the splints of the watch and the escape wheel member 8 and the escapement fork member 9 are mounted and fixed on the rotary support 7. At this time, since the rotary bracket 7 and the second gear shaft 10b are rotated in synchronization, the escape wheel member 8, the pallet fork member 9, and the balance spring assembly 11 revolve around the fixed second wheel plate 10. The escapement wheel component 8 drives the escapement fork component 9 to do reciprocating swing around the point a through a special gear, and the balance hairspring component 11 is driven to do regular oscillating swing through the fork b during the swinging, so as to generate a timing source. The single-shaft rotary tourbillon watch can continuously rotate at a certain speed due to the fact that the whole escapement speed regulating mechanism is combined together. The gravity impact on the escapement system in the mechanical watch can be reduced to the minimum, the error of gravity on the clock parts can be corrected, and the time precision is improved. The tourbillon watch adopting the rotary tourbillon mechanism has brought into play with the dynamic artistic beauty of the clock to the ground step of peak climbing and pole making due to the unique operation mode, and has been known as the 'king in watch'.
However, the theoretical data and perfect conception of the tourbillon are not all at the same time, subject to the constraints of various factors such as process, materials, etc. The 1.0 edition one-dimensional plane tourbillon mechanism originally created in the current year cannot meet the requirement of 360 degrees of rotation in the optimal time period. In a quite long time, the tourbillon mechanism can not open a space for further improving the precision while eliminating the travel time error.

The invention relates to an operating principle of an oval sphere cage type double-shaft rotary escapement speed regulating mechanism: the spring power is transmitted to the bowl-shaped seconds wheel component 1, the bowl-shaped seconds wheel component 1 rotates to drive the vertical seconds wheel 2 to rotate, and the vertical seconds wheel 2 and the oval sphere cage 3 are fixedly connected through the supporting shaft, so that all parts (seconds passing one wheel component 4, seconds passing two wheel components 6, an inner frame rotating bracket 7, an escape wheel component 8, an escape fork component 9, a fixed seconds wheel piece 10 and a balance spring assembly 11) in the oval sphere cage 3 rotate synchronously with the vertical seconds wheel 2 (rotate around an X axis). The rotation of the oval sphere cage 3 causes the second passing one wheel member 4 (the axis of the second passing one wheel member 4 is fixed to the oval sphere cage 3) to rotate in engagement (rotate about the longitudinal axis) about the bowl-shaped fixed wheel plate 5, causing the second passing one wheel member 4 to receive a rotational torque which in turn causes the second passing two wheel member 6 to rotate.

The fixed seconds wheel 10 is mounted and fixed to the oval sphere cage 3 (specifically to the fixed seconds wheel support 15 within the oval sphere cage 3), so the fixed seconds wheel 10 is stationary relative to the oval sphere cage 3. At this time, since the inner frame rotary bracket 7 and the second pass two wheel member 6 are rotated in synchronization (rotated about the Y axis), the escape wheel member 8, the pallet fork member 9 and the balance spring assembly 11 are made to revolve around the fixed second wheel plate 10. The escapement wheel component 8 drives the escapement fork component 9 to do swinging motion around the point a through a special gear, and the balance hairspring component 11 is driven to do regular swinging motion through the fork b during swinging, so as to generate a timing source.
All parts (second passing one wheel part 4, second passing two wheel part 6, inner frame rotating bracket 7, escape wheel part 8, escape wheel fork part 9, fixed second wheel piece 10 and balance spring assembly 11) in the outer frame oval sphere cage 3 of the whole mechanism rotate clockwise around the X axis in the rotating direction of working, and all parts (second passing two wheel part 6, inner frame rotating bracket 7, escape wheel part 8, escape wheel fork part 9 and balance spring assembly 11) on the inner frame rotating bracket 7 rotate clockwise around the Y axis, and the rotating period of the inner frame and the outer frame is 60 seconds.
The invention has the following structural characteristics:
1. in the structural design of the elliptic sphere hollow cage frame, the concept of warp and weft on the globe is introduced, so that the hollow cage frame with uniform stress can be ensured to firmly support the normal operation of the inner shaft tourbillon mechanism in the rotation around the supporting shaft, and the inner shaft tourbillon mechanism can be viewed through the elliptic sphere hollow cage frame to work.
2. The structure adopts two sets of bowl-shaped gear driving structures (the bowl-shaped second wheel part 1 is meshed with the gear of the vertical second wheel 2, the bowl-shaped fixed wheel piece 5 is meshed with the gear of the second passing wheel part 4), so that the spring moment is effectively transmitted to two driving shafts (X, Y rotating shafts). The bowl-shaped gear has the advantages that the torque transmission angle can be changed by 90 degrees, and the torque transmission is ensured to be efficient and stable.
3. When the two rotating shafts work, 360-degree rotation is carried out simultaneously, so that the escapement speed regulating mechanism naturally forms different displacement processes of an upper surface, a lower surface, an upper standing position and a lower standing position, and two-rotation (namely rotation in two directions of an X axis and a Y axis) are integrated and repaired in multiple, and the efficiency of eliminating errors of the tourbillon is obviously expanded. Is not accessible to a single-shaft rotary escapement speed regulating mechanism (a common tourbillon).
4. Four shaft-type dampers 12 are provided on each of the two rotation shafts X, Y. When the watch works, the four shaft type shock absorbers can effectively defend the interference of external impact force, and ensure the working reliability of the double-shaft rotary escapement speed regulating mechanism.
