Embodiment Construction

[0021] In the following description reference will be made to a timepiece movement equipped with a motor module. Common parts of a timepiece movement, well known to those skilled in the art, are only described in simplified form, or are not described at all. Those skilled in the art know how to adjust and coordinate these various components to achieve the operation of a timepiece movement.

[0022] figure 1 with 2 Part of a timepiece 1 including a timepiece movement 2 is shown. The timepiece 1 is, for example, a mechanical watch or a quartz watch. Clock movement 2 includes such as Figures 1 to 4 Shown is a motor module 4 according to a first embodiment of the invention. The motor module 4 is configured to be fixed to a printed circuit board (not shown) of the timepiece movement 2 , for example by screwing, gluing or heat riveting. The motor module 4 includes a machine plate 6 and a gear bridge splint 8 mounted on the machine plate 6 . The motor module 4 also includes a...

Abstract

The invention relates to a motor module (4) for a timepiece movement (2), comprising a board (6) carrying one or more gears (12) and a gear bridge (8) mounted on the board (6), characterized in that the gear bridge (8) comprises means (18) for clamping the gear bridge (8) on the board (6).

Description

technical field [0001] The invention relates to a motor module for a timepiece movement. Such a motor module is intended in particular for driving the hands of a timepiece comprising a timepiece movement. [0002] The invention also relates to a timepiece movement comprising such a motor module, and a timepiece comprising such a timepiece movement. For example, the timepiece is a watch. [0003] The invention also relates to a method of assembling such a motor module. Background technique [0004] Modular timepieces are known. It is very common in electronic watchmaking, but less so in mechanical watchmaking, where modular construction is often designed to break down the same basic mechanical movement into components with different functions or different appearances. Multiple movements, which rarely prove to be less expensive than traditional manufacturing. Only some additional mechanisms fabricated on add-on boards are relatively common. One of the main modules of thi...
