<p>#CMT# #/CMT# The balance (1) has an inertia counterweight (7) arranged on a peripheral felloe in a housing (8), and comprising a circular profile guiding unit (9) complementary to a circular complementary guiding unit (9A). The counterweight comprises two adjustable parts i.e. studs (10, 11), adjustable in translation with respect to each other in a plane parallel to a balance plane (4). One of the adjustable parts is immovable in translation with respect to the felloe, where each adjustable part of the counterweight is made of material that is highly denser than the material constituting the felloe. #CMT#USE : #/CMT# Balance for a balance wheel of a high frequency oscillator to adjust oscillation frequency of an inertia adjustable timepiece (all claimed). #CMT#ADVANTAGE : #/CMT# The design of the balance ensures high quality factor, allows elimination of whiplash, limits the mass of the balance and reduces the number of components for constituting the timepiece. The balance is regulated and adjustable in a precise manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic perspective view of a balance. 1 : Balance 4 : Balance plane 7 : Inertia counterweight 8 : Housing 9 : Circular profile guiding unit 9A : Circular complementary guiding unit 10, 11 : Studs.</p> |
