Embodiment Construction

[0018] The adjustment of the balance wheel gap is essential to the correct operation of the mechanical movement. To this end, the Applicant proposes a fixture 100 for adjusting the play of a balance wheel 200 . The at least one securing device 100 includes at least one bolt retainer 110 , at least one bearing body 120 , at least one support member 130 and at least one retaining member 140 .

[0019] Such as figure 1 As shown in , the at least one bearing body 120 is configured to move relative to the at least one bolt retainer 110 by thread tapping.

[0020] In fact, according to an embodiment, the at least one bearing body 120 may include tapped or screw threads provided on the outer periphery of the at least one bearing body 120 . The at least one bolt retainer 110 may then include threads or taps provided on the inner periphery of the at least one bolt retainer 110 so that the at least one bearing body 120 can be screwed to the at least one bolt retainer 110 . Pin holder...

Abstract

The invention relates to a fixing device (100) for adjusting the clearance of a balance wheel (200). The at least one fixing device (100) comprises at least one pin holder (110), at least one bearing body (120), at least one support member (130) and at least one retaining member (140). The at least one bearing body (120) is configured to move relative to the at least one pin holder (110) in order to fix the adjustment of the clearance of the balance wheel (200), and the at least one support member (130) is configured to press the at least one bearing body (120) against the at least one pin holder (110) prior to being held by the at least one holding member (140).

Description

technical field [0001] The invention relates to the field of watchmaking. It relates more particularly to the fixing device for adjusting the clearance of the balance wheel. Background technique [0002] The adjustment of the balance wheel gap is essential to the correct operation of the mechanical movement. Equally important is the positioning and locking of the stud holder and the balance damper. In most mechanical movements, a shock absorber is driven into the balance cock, which itself locks the pin holder. [0003] In order to adjust these two elements, significant forces need to be exerted on these elements, which is burdensome and can lead to degradation of said elements and their environment. Contents of the invention [0004] The invention relates to a fixing device for adjusting the play of a balance wheel, preferably for adjusting the play of said balance wheel; said at least one fixing device comprises at least one pin holder, and: [0005] - at least one b...
