Problems solved by technology

This inefficiency is due to the fact that the escapement moves jerky, there is a "fall angle play" (running to the pendulum point to accommodate machining errors) and also because the multiple components transmit their motion via inclined planes that rub against each other

Embodiment Construction

[0026] The invention relates to a mechanical watch 1000 provided with a movement 500 comprising a resonator 100 mounted on a main plate 1, the resonator having a flexible balance and bearing such as Figure 13 The torque continuity of the drive device 300 shown maintains the mechanism 200 .

[0027] exist figure 1 The flexible gimbal shown in and described in detail below has the function of locking the inertial element 2 and the main board 1 of the resonator 100 in three translations and the first rotation while making the second and third rotations flexible.

[0028] The axis of rotation of the flexible rotation is vertical and passes through the center of mass G of the inertial element 2 of the resonator 100 .

[0029] The invention is shown here with a single inertial element 2 in a non-limiting manner.

[0030] The figures show that each mechanism has a main axis D, a first axis D1 and a second axis D2.

[0031] figure 2 The general definition of Euler angles is spec...

Abstract

The invention relates to a movement (500) including an escapement mechanism (200) and a resonator (100) including an inertial element (2) subjected to the action of a flexible gimbal (3) and cooperating with an escape wheel set (4) pivoting about a main axis (D). The escape wheel set includes driving means (40) cooperating in a continuous transmission of motion with complementary means (20) of theinertial element (2) in every angular position of the latter, the flexible gimbal (3) tending to return these complementary means (20) towards the main axis (D), and including elastic return means (31; 32) about axes orthogonal to the main axis (D) and restricting the mobility of the inertial element (2) in two rotational degrees of freedom, about a fixed position of the centre (G) of inertia ofthe inertial element (2) with respect to a plate (1).

Description

technical field [0001] The invention relates to a timepiece movement for a mechanical watch, comprising a resonator mechanism arranged on a main plate and an escapement mechanism subjected to the torque of a driving device included in said movement, said resonator mechanism comprising an inertial element arranged to oscillate relative to said mainboard, said inertial element being subjected to the action of elastic return means fixed directly or indirectly to said mainboard, and said inertial element being arranged to cooperate with said escapement An escape wheel set that is included and pivots about the main axis cooperates. [0002] The invention also relates to a mechanical watch comprising at least one such movement. [0003] The invention relates to the field of resonator mechanisms forming the time base of mechanical watches. Background technique [0004] Most current mechanical watches consist of a balance / hairspring-type resonator that forms the time base of the w...
