REDUCED-CONTACT OR CONTACTLESS FORCE TRANSMISSION IN A CLOCK MOVEMENT

摘要

The invention relates to a method for carrying out controlled-contact, attenuated-contact or contactless transmission in a clock movement. The method comprises providing or transforming at least one pair of antagonistic components of said clock movement, one of said components driving the other or engaging with the other, by applying a treatment on the surface thereof or within the body thereof at antagonistic surfaces, said treatment imparting an electrostatic and/or magnetic charge to said components, said charge having the same polarization and/or magnetization, such that said antagonistic components tend to repel each other when brought closer to one another. Said treatment consists of forming or depositing at least one thin film on said engagement surface and/or on said antagonistic engagement surface. The invention also relates to a clock mechanism including at least one pair of antagonistic components, one of said components driving the other or engaging with the other, said pair being provided or transformed by implementing said method.
