The hand setting system(140) meets the core structure requirements of the rotational and revolutionary flying tourbillon.

Description

Tourbillon mechanical watch with both rotation and revolution

The present invention relates to a mechanical watch with a tourbillon, and more particularly to a tourbillon mechanical watch with both rotation and revolution.

Background technique

The so-called tourbillon in mechanical watches is a device that reduces the isochronous error. The device is characterized in that the balance spring system and the escapement are placed in the frame, and can rotate with the frame while running. The accuracy of the travel time is improved by minimizing the position error of the watch caused by the gravity of the earth. The device in which the axis of the balance spring system coincides with the rotation axis of the frame (refer to the patent "watch coaxial rotary escape speed governing mechanism" patent number: LZ200720096902.5) is called "coaxial tourbillon"; A device commonly referred to as "Carrousel" whose axes do not coincide (refer to EP Patent Publication No. 846987) is referred to as an "eccentric tourbillon".

At present, a tourbillon watch has a track tourbillon in which the tourbillon is placed on a rotatable turntable so that it is rotated around the center line of the turntable. The tourbillon watch is characterized in that the tourbillon is equivalent to the planetary wheel in the epicyclic gear train that can both rotate and revolve under the rotation of the turntable, which makes the trajectory of the balance spring system and the escapement more complicated, but It can better reduce the position error of the clock caused by the gravity of the earth and improve the travel time accuracy.

The key part of the orbital tourbillon is the turntable mechanism, which connects the prime mover, the display system, the drive train and the tourbillon to form a complete movement. According to CN Patent Publication No. 1841242A, CN Patent Publication No. 1950759A, CN Patent Publication No. 200972574Y Both the FR Patent Publication No. 2784203 are orbital tourbillons.

FR Patent Publication No. 2784203 and CN Patent Publication No. 1841242A are to mount a tourbillon, a motive mechanism for driving a tourbillon, and a transmission mechanism connecting them on a rotating disk such that they both rotate on the center line of the rotating disk, although This structure has the advantage to some extent, that is, the motive system can transmit energy directly to the tourbillon without passing through the differential device. However, their upper part is very complicated, and FR Patent No. 2784203 needs to be wound by a special device on the back of the movement, and the upper part of CN Patent No. 1841242A is designed as a double planetary gear mechanism. Its parts processing is quite difficult.

CN Patent Publication No. 1950759A is implemented by mounting a tourbillon and a transmission mechanism on a rotating disc, and the motive mechanism for driving the tourbillon is placed under the rotating disc to be stationary, and the upper strip portion adopts a common structure, and Its needle system needs to adjust the time by driving the entire turntable mechanism including the tourbillon and the transmission mechanism to make the hour wheel and the minute wheel rotate rapidly and drive the minute and minute hands to adjust the time. However, the disadvantage of this type of construction is that the load driven when the needle is set is too heavy and requires too much torque.

The patent applications mentioned above, although their turntable mechanisms are structurally different, they all employ ball bearings as pivotable pivots for the turntable mechanism. The disadvantage of the ball bearing is that the adjacent rolling elements will be in direct contact, and the relative friction speed is twice the surface speed, the heat and wear are relatively large, and pitting, plastic Sexual deformation, abrasive wear, adhesive wear and other failure modes will affect their service life, so they will consume part of the spring torque, shorten the watch's travel time and reduce the travel time accuracy.

The turntable 34 rotates clockwise at a speed of one hour every 12 hours. Under the driving of the turntable 34, the tourbillon and the transmission wheel train take the center line of the turntable 34 as an axis, and the speed of one turn every 12 hours clockwise. Since the rotation speed of the first center wheel 2 is 12 times that of the second center wheel 4, the first center wheel 2 rotates clockwise at a speed of one hour per hour, and drives the minute wheel 24 to rotate clockwise at the same speed. The wheel 24 drives the minute hand 27 to indicate time. Since the rotation speed of the minute wheel 24 is 12 times that of the first hour wheel 25, and the first hour wheel 25 and the second hour wheel 26 rotate simultaneously, the second hour wheel 26 rotates clockwise and drives at a speed of one every 12 hours. The hour hand 28 indicates time.

From the structural analysis, the rolling elements are circulated in the bearing ring, so only the bearing needs to be filled with permanent lubrication. Fat is acceptable. Roller bearings with multi-layer gaskets for cylindrical rollers can also be removed as a single plate, easy to repair, simple and convenient.

Secondly, in the embodiment of the present invention, a ball bearing is formed by a combination of a splint, a stud, a screw and a gemstone, which is different from the ball bearing used in the existing track tourbillon, and the ball bearing used in the present invention is combined. The splint used can also be used to control the support on other drive trains by setting the gemstones.

It should be noted that the tourbillon used in this embodiment is a coaxial tourbillon, and the scope of protection of the present invention is not limited to the above specific example manner. According to the basic technical concept of the present invention, the transmission can be basically the same. As shown in FIG. 12 and FIG. 13, the embodiment of the present invention can still achieve the object of the present invention by using an eccentric tourbillon, as long as those skilled in the art do not need to work creatively, the embodiments that can be conceived belong to the protection of the present invention. range.
