Abstract (en)
[origin: EP1837719A1] The wheel has a felloe (3), and four arms (4) connecting the felloe to a balance wheel axis. Counterweights (11) permit to adjust an unbalancing mass and a movement of inertia. The felloe (3) comprises studs (7) radially directed towards its interior, where the felloe and the studs are traversed by a threaded hole (9) in which the counterweights are screwed from the interior of the felloe. The studs are arranged on an inner surface of the felloe, where the felloe is made of copper beryllium and the studs are made of titanium.
