Floating rotation tourbillion mechanical watch

Abstract

The invention discloses a floating rotation tourbillion mechanical watch which comprises a winding series, a basic series A, a needle setting series, a transition series B and a rotation series C. The basic series A comprises an initiative series, a display series and a transmission wheel series. The transition series B comprises a ball support part and a planet wheel series. The rotation series C comprises a transmission wheel series and a rotation escapement speed regulating mechanism. The winding series, the initiative series and the display series are connected in sequence. The needle setting series is connected with the display series. The display series is sequentially connected with the transmission wheel series included by the basic series A, the planet wheel series and the ball support part which are included by the transition series B, and the transmission wheel series and the rotation escapement speed regulating mechanism which are included by the rotation series C in a double-direction mode. The floating rotation tourbillion mechanical watch has the advantages that due to the fact that a sun wheel is of a friction structure, a friction function is achieved through elastic deformation of a leaf spring between a clamping plate and the sun wheel, a needle setting wheel series drives the sun wheel directly to adjust the position of a rotation support, stability is strong. In addition, friction loss of contacted faces and rotation parts is reduced by the ball support structure, the structure is simple, and performance is stable.

Description

technical field [0001] The invention relates to a mechanical watch with a tourbillon, in particular to a mechanical watch with a floating and rotating tourbillon. Background technique [0002] At present, a floating rotating tourbillon has appeared in the tourbillon watch. The tourbillon is placed on a rotatable bracket, so that it performs epicyclic motion around the center line of the rotating bracket. The feature of this tourbillon watch is that the tourbillon is equivalent to the planetary wheel in the epicyclic wheel system, which can not only rotate on its own, but also revolve under the drive of the rotating bracket. The rotating bracket rotates once per hour and can be used as the minute hand of the movement. [0003] In the prior art, the tourbillon and the transmission mechanism are installed on the rotating bracket, and the driving train driving the tourbillon is arranged under the rotating bracket to be stationary, and the rotation of the rotating bracket is to...

Problems solved by technology

The rotating bracket extends to the outer edge of the movement, and the artificial gemstones cooperate with the upper and lower planes of the movement casing, which is conducive to the axial balance of the entire rotating bracket, but it undoubtedly increases the difficulty of the movement casing design, and the sliding friction generated by the mating surface is also difficult. Increased loss of clockwork torque
