Embodiment Construction

[0030] The invention relates to a composite timepiece wheel 1 with a play adjustment mechanism, comprising an external toothing 2 each tooth 3 of which comprises a first half-tooth 4 on either side of its middle part and a second half-tooth 5 comprising a first part 40 of the tooth profile and a second half-tooth 5 comprising a second part 50 of the tooth profile. Each first half-tooth 4 can move relative to the second half-tooth 5 of the same tooth 3 against elastic return means 6 which tend to keep the first half-tooth 4 and the second half-tooth 5 of the same tooth 3 apart exercise each other.

[0031] The wheel 1 according to the invention is arranged to work in both directions of rotation.

[0032] According to the invention, the wheel 1 comprises a first half-wheel 400 carrying all first half-teeth 4 , axially superimposed on a second half-wheel 500 carrying all second half-teeth 5 .

[0033] The first half-wheel 400 and the second half-wheel 500 have limited rotationa...

Abstract

The invention relates to a timepiece wheel (1) with play take-up, including a toothing (2), each tooth (3) of which includes first and second half-teeth (4, 5) each including a part (40, 50) of the tooth profile, and movable with respect to each other against elastic return means (6), the wheel (1) including, axially stacked, a first and a second half-wheel (400, 500) respectively carrying the first and second half-teeth (4, 5) and having limited rotational mobility with respect to each other, about the axis of this toothing (2), and against the elastic return means, the toothing of each half-wheel (400, 500) overhanging the other half-wheel, each half-wheel including hollows (41, 51) inside each of which is movable an opposite half-tooth, between two successive half-teeth (4, 5).

Description

technical field [0001] The invention relates to a compound clock wheel with a play adjusting mechanism, comprising an external toothing, each tooth of which comprises a first half-tooth and a second half-tooth on either side of its middle part, The first tooth half comprises a first portion of the tooth profile, the second tooth half comprises a second portion of the tooth profile, each first tooth half can resist tending to move the first and second half teeth of the same tooth away from each other The moving elastic return means moves relative to the second tooth half of the same tooth. [0002] The invention also relates to a timepiece train comprising at least one such wheel and a complementary wheel. [0003] The invention also relates to a timepiece movement comprising at least one such timepiece wheel train or comprising at least one such wheel. [0004] The invention also relates to a watch comprising such a movement or comprising at least one such horological train ...
