Problems solved by technology

A disadvantage of components made of crystalline materials is their low mechanical strength when high stresses are applied
So there is a process of teeth pushing and sliding to cause the gear train to turn

Embodiment Construction

[0036] figure 1 with figure 2 The escapement 1 is shown with a resonator 3 , that is to say a balance with hairspring. In general, resonator 3 cooperates with escapement 1 with the assistance of disc 5 mounted on the axis of the balance wheel. The escapement system 1 comprises a main face (see figure 1 ) The Swiss anchor pallet fork 7 formed. The Swiss anchor 7 is mainly formed by a rod 9 connecting a prong 11 and an arm 13 . Prong 11 comprises two cornes 15 facing each other, below which are mounted prong pins 17 which engage respectively with pins fixed to said disc 5 of the axis of the balance wheel. Cooperate with the bottom of said disc 5.

[0037]Between the two arms 13 , the lever 9 receives an arbor 19 for the rotatable mounting of the anchor between the bridges and the baseplate of the movement. Finally, fitted on each arm 13 is a fork 21 intended to come into contact with escape wheel 23 through its teeth 25 . As an example, the prong tiles may be formed from...

Abstract

The invention relates to an escapement system (1). The system comprises an anchor pallet (7) fitted with a fork for cooperating with a pin mounted on a disc (5) and a lever including an arm for receiving the fork (21) in order to cooperate with at least one escape wheel (23). A portion of the escapement is made of an at least partially amorphous metal alloy.

Description

[0001] This application is a divisional application of the patent application No. 201180031085.4 (PCT / EP2011 / 060511), the filing date of the original application is June 22, 2011, and the name is "Escapement system for clocks and watches". technical field [0002] The invention relates to an escapement system. The escapement system comprises an anchor pallet fitted with a munie head for cooperating with a pin mounted on a disc, and a rod comprising an arm for receiving a pallet in order to communicate with at least one Escape wheel cooperation. [0003] The technical field of the invention is that of precision mechanics, and more particularly of watchmaking. Background technique [0004] A timepiece includes an energy source, such as a barrel, that supplies energy to parts and especially a gear train. These gear trains cooperate with the escapement system via the escape wheel. The rotation of the escape wheel is regulated by the anchor pallet fork of the escapement system...
