Composite balance and method of manufacturing thereof

摘要

The balance (45') has a hub (39') connected to a felloe (37') by arms (40'-43'), where composite balance is formed in a silicon based layer. The felloe has a crenated ring (23') whose density is higher than that of the silicon based layer for increasing inertia of the balance. The ring is mounted in a recess formed in one of main surfaces of the felloe. A cylinder (25') is mounted on one of main surfaces of the hub, where the cylinder and the crenated ring are formed from metallic material. An independent claim is also included for a method for fabricating a composite balance.
