Embodiment Construction

[0018] Now refer to the figure 1 and figure 2 The invention will be described with respect to the components of a timepiece movement shown in FIG. To simplify the description, this example refers specifically to an escapement system, but it should be understood that the invention is not limited to this specific embodiment and includes any timepiece component subject to friction.

[0019] exist figure 1 In the example shown, an escapement 1 for a timepiece can be seen. The escapement system 1 comprises in particular an escapement movable part 3 comprising an escapement wheel coupled with the escapement pinion and pivotally mounted on a shaft 30 , a pivotably mounted on a pallet shaft The pallet fork 2 on 23 and the disc 4 embedded on the balance shaft 40. Disc 4 comprises the small disc 41 that is provided with fork groove 42 and is provided with pin (in figure 1 Not shown in the large plate 43. Pallet fork 2 comprises an arm 21 comprising a levee 22 cooperating with a p...

Abstract

The present invention concerns a component having a surface subjected to friction, wherein at least a portion of said surface is formed from a material comprising fibroin. The fibroin can be applied as a thin layer to the surface, or the component itself can comprise a composite material incorporating fibroin in a suitable matrix. Moreover, the invention also concerns components formed entirely from fibroin.

Description

technical field [0001] The invention relates to components of timepiece movements which are subject to friction and require good friction properties. In particular but not exclusively, the invention relates to bearings, gear trains, escapements or mainsprings of watches. Background technique [0002] In the field of microtechnology, which will subsequently be explained more particularly by the field of horology, it is known to lubricate components having surfaces subjected to friction. Lubrication is usually achieved by applying lubricating oils or lubricants, usually based on hydrocarbons, fluorocarbons or silicones. However, this solution is not without drawbacks. [0003] Oils and lubricants undergo degradation in their lubricating ability over time due to chemical changes as well as contamination, so that any movement lubricated by these means should be periodically disassembled, cleaned and re-lubricated. [0004] In the field of microtechnology, and especially in th...
