Embodiment Construction

[0018] Figure 1 shows various components of an embodiment of the method according to the invention. Thus, there are pivoting parts, a term that includes various parts intended to be mounted on a mobile by its rotation. As shown in Fig. 1, the pivot member may be a shaft 10 having a tubular portion and a not shown end forming a pivot.

[0019] The shaft 10 comprises a disc 12 extending radially around the shaft 10 . This disc 12 forms a bearing surface. It can be disc-shaped. According to a preferred embodiment, the disc is provided on one of its surfaces with an annular groove 14 arranged around the axis. The shape of the groove is not critical. In particular for the method described in this example, the groove is arranged next to the base of the shaft, with at least one open area on the shaft.

[0020] A malleable piece, generally a ring-shaped plastic spacer 16, is also used in the method according to the invention. The gasket 16 may be metallic or synthetic and may ex...

Abstract

The method involves forming a rotational body i.e. axle (10), with a tubular portion. A bearing surface (12) is extended around the tubular portion. A hard part (18) is freely introduced on the body and pulled to contact with a malleable element i.e. annular washer (16), by an entry (20) of its structure, so that the element is set over the entry. An assembly is formed by the part and the element to bear a support surface. The element is irreversibly deformed to create catches (24) and housed inside the structure without any degree of freedom. The element is integrated with the body.

Description

technical field [0001] The present invention relates to a method for assembling hard parts on pivoting members. By pivoting member is meant a shaft or a hollow shaft for receiving the shaft. Background technique [0002] The materials used in watchmaking have evolved significantly in recent years. In particular, growth and etching techniques developed for other microtechnology industries offer particular opportunities for application in watchmaking. However, most of these new materials, such as silicon or diamond, have no or very little plastic field, that is to say they cannot undergo plastic deformation. Commonly used mounting parts, such as drive methods of mounting wheels on axles, cannot be used because these methods will crack the parts. [0003] In order to overcome this disadvantage, solutions have been proposed which consist in mounting an elastic structure on the hub of the part, enabling the part to be mounted on the shaft. This construction requires the provi...
