Embodiment Construction

[0033] The invention relates to the field of horology and more particularly to the field of assembly and repair of components, in particular fixing display components, hands, discs and the like.

[0034] As can be seen in the figures, the invention relates to a timepiece subassembly 10 comprising a bushing 2 for guiding a pivoting wheel set 3 on a base plate 1 with The convex shoulder 21 matched with the concave cavity 11 and the stop surface 22 abutting against the bottom plate 1 .

[0035] According to the invention, this subassembly 10 comprises thrusting means 5 fixed on the wheel set 3 . The wheel set 3 equipped with the pushing device 5 is as Figure 6 and Figure 6A Sliding relative to bushing 2 shown in , there is a defined end clearance E between:

[0036] - on the one hand, a first stop position between the collar 31 of the wheel set 3 and the front end face 24 of the bushing 2,

[0037] On the other hand, a second stop position between the stop face 51 of the th...

Abstract

The invention refers to a pre-adjustment of the play of a horological wheel. Timepiece sub-assembly including a spacer for guiding a pivoting wheel set on a bottom plate and including a shoulder for cooperating with a housing in said bottom plate and a stop surface for abutting against said bottom plate. It includes a drive means fixed to said wheel set, arranged to slide relative to said spacer with an axial shake, determined between a first stop position between a collar of said wheel set and a front face of said spacer, and a second stop position between a stop surface of said drive means and a rear face of said spacer. Said wheel set includes, opposite said collar, a machined portion arranged to cooperate with a complementary machined portion of a display element to fixedly secure said display element to said wheel set.

Description

technical field [0001] The invention relates to a timepiece subassembly comprising a base plate, a wheel set and a spacer for guiding the pivoting wheelsets on said base plate, said spacer comprising a A shoulder cooperating with a cavity in and a stop surface arranged to abut against said bottom plate. [0002] The invention also relates to a timepiece movement comprising at least one such subassembly, wherein said baseplate has a cavity extending along a first cavity axis, said cavity being carried on at least one face of said baseplate by a first A surface surrounds the first axis. [0003] The invention also relates to a timepiece comprising at least one such timepiece movement, or comprising at least one said base plate comprising a cavity extending along a first cavity axis, said cavity being formed in at least one of said base plate One face is surrounded by a first bearing surface around said first axis, and said timepiece has at least one subassembly arranged to coo...
