    摘要： A balance wheel-spring system including a balance wheel that oscillates about a balance wheel shaft and a spring, one inner spiral of which is fixed to the balance wheel shaft or to a collet mounted integrally with the shaft and one outer spiral of which is fixed to a stud integral with a bridge. The balance wheel includes a hub, a rim, an arm connecting the hub to the rim, a front face which includes a countersink and a rear face, the arm including a housing receiving and retaining a flyweight, and the spring being mounted opposite the front face of the balance wheel. The flyweight is mounted on the arm on the rear face of the balance wheel, the distance between the bottom of the countersink of the front face of the balance wheel and the spring is a predetermined interval between 0.05 mm and 1.50 mm.

    摘要： A method of improving pivoting of a wheel set for a scientific instrument, including an arbor pivoting or oscillating about an axis, in which: static balancing of the wheel set is performed to bring the center of gravity onto the axis; a desired value is determined for resulting unbalance moment of the wheel set about the axis, corresponding to a predetermined divergence between a first principal longitudinal axis of inertia of the wheel set, and the axis; at a predetermined speed about the axis, the resulting unbalance moment is measured with regard to the axis; and an adjustment of the resulting unbalance moment is made within a given determined tolerance with regard to the desired value, and performed by machining both sides of a median plane including the two secondary axes of inertia of the wheel set.

    摘要： A balance for a horological movement includes rigid portions consisting of a hub defining the pivot axis of the balance, a felloe, four arms connecting the felloe to the hub, and including four slots for receiving and gripping in position an inertia-block, each slot being delimited by an arm and by an elastic arm including a first end integral with the arm, and a second distal end free in relation to the hub, to the arm, and to the felloe sector. The balance includes two pairs of inertia-blocks, each pair of inertia-blocks having different masses to ensure different adjusting powers, a first pair of inertia-blocks for a basic adjustment, and second pair of inertia-blocks for a precise adjustment.
