Abstract
In the clockwork, according to the present invention, the bearing journals of the balance staff, and also of the pallet staff, have a larger diameter than in known clockworks, since a DLC coating of these bearing journals and the corresponding surfaces of the bearings provides for very low friction, which enables an increase in the bearing journal diameter without diminishing the function and accuracy. The enlargement of the bearing journal diameter results in improved shock-resistance in addition to making the elements provided for shock resistance in conventional clockworks (spring-mounted bearings for the balance staff) partially, or wholly, unnecessary.
Claims31
A mechanical clockwork for pocket watches and wrist watches, with a mechanical escapement that cooperates with a mechanical oscillating system comprising at least one escape wheel, and one anchor, said anchor having areas, cooperating with said at least one escape wheel, said anchor and said areas, or said escape wheel and areas having a DLC coating.
A clockwork for pocket watches or wrist watches comprising a balance staff with bearings on both ends that can move in a plate or on a plate element, wherein the balance staff has at least one end that can move in a plate or on a plate element, wherein the balance staff has at least one end that can move in a bearing possessing a bearing ring and bearing elements within the bearing ring and enclosing the balance staff, and wherein the bearing elements are made of silicon carbide, a ceramic materials or a synthetic ruby.
