Description

Tourbillon in mechanical clock movement

Technical Field

The present application relates to the field of tourbillon timepiece components, in particular to a tourbillon in a mechanical timepiece movement.

Background

The tourbillon is a timepiece speed regulating device invented in 1795 by mr. cursory & breguet of switzerland timekeeper. The French Tourbillon (also known as Torbillon) has the meaning of "vortex", derived from French mathematician Cartesian to describe the term of revolution of a planet around the sun, applied to the clock world to refer to a mechanical watch equipped with a "rotational escapement speed regulation mechanism", a Tourbillon mechanism, in order to correct the errors caused by gravity on the clock parts.

The tourbillon represents the highest level in the manufacturing process of a mechanical watch, and the whole escapement speed regulating mechanism is combined together and can rotate continuously at a certain speed, so that the influence of gravity on an escapement system in the mechanical watch is reduced to the minimum degree, and the travel precision is improved.

In a common mechanical watch, the balance spring in the escapement system is affected by tightness and metal fatigue, and the law of the balance wheel swing is also affected by gravity, so that the error is large. The idea behind the tourbillon is to place the escapement of the timepiece core in a frame that rotates regularly through 360 ° around the axis, i.e. the axis of the balance. Therefore, the original escapement mechanism is fixed, so that when the resting position of the watch is changed, the escapement mechanism is unchanged, and errors are generated due to different stress of escapement parts; when the escapement mechanism rotates by 360 degrees ceaselessly, the azimuth errors of the parts are integrated and mutually offset, so that the errors are reduced to the maximum extent. At present, most tourbillons make one revolution (360 °) in 1 minute, which is also an ideal rotation speed recognized in the industry.

Tourbillon escapement devices play a considerable role in overcoming the above-mentioned series of effects. In particular, in the pocket watch era of the year, the rotary escapement greatly improves the travel accuracy of the timepiece. However, since the gravity distribution of many tourbillon adjusting devices is not uniform, the tourbillon adjusting devices themselves have certain errors, and the accuracy of travel time can be deepened due to the error caused by gravity.
