摘要： An element for radial guiding of a pivot of a rod of a rotating wheel, for example a rod of a balance, for a bearing of an horological movement, in particular shock-absorbing, the guide element including a body configured to cooperate with a bearing unit in such a way as to be maintained in the unit, the body defining a space for radial retention of the pivot, to maintain the rod radially while allowing it to rotate. The radial guide element includes at least three localized radial-bearing parts distributed angularly, the three parts defining the radial retention space, each part having a face for contact with the pivot, each face locally having a cylindrical shape convex towards the inside of the radial retention space, the bearing parts having an elongated body.

摘要： The device for pivoting an arbour (11) in a timepiece, includes two pivots (12, 12′; 32) each forming one end of the arbour and two bearings for receiving the two pivots. Each of the pivots includes an approximately cylindrical portion (19, 19′; 39) and a convex rounded portion (13. 13′; 33) that extends the approximately cylindrical portion and gradually decreases in the direction of the end. Each of the bearings includes a pivoting structure (25; 35) held in place elastically, which includes an approximately cylindrical passage traversed by said approximately cylindrical portion (19, 19′; 39) of one of the pivots. The pivoting structure also includes a bearing surface against which the end of said pivot will abut. The pivoting device is characterized in that the pivoting structure of each of the bearings includes an aperture (16, 16′; 36; 46) that has a portion of inverted triangular or trapezoidal profile (16, 16′; 38; 46), and in that the convex rounded portion (13, 13′; 33) of one of the two pivots is for abutting against said inclined inner wall so that the arbour (11) is held axially between the inclined walls of the apertures of the two bearings.

摘要： 667,395. Watches. ANNEN, R., and ROULEMENTS A. BILLES MINIATURES SOC. ANON. April 29, 1949, No. 11522/49. Class 139. The rocking weight in a self-winding watch is supported on a ball bearing having at least three raceways. In the first example (Fig. 1), four raceways are provided, two on an inner ring or race 5 held on a pillar 6 1 by a screw 7, and the other two on relatively adjustable rings 2 and 3. The ring 2 is carried by the arm 1 of the winding weight and constitutes the first pinion of the winding train. The ring 3 is forced into the ring 2. In another example (Fig. 2, not shown), the ring 3 constitutes the first pinion of the winding train and is positioned below the ring 2. In another embodiment (Fig. 3), the two outer raceways are on separate rings 11, 12, both forced into a ring 10 set in the arm 1. The ring 10 constitutes the first pinion of the winding train. In another embodiment (Fig. 4, not shown), the lower outer ring 12 forms the said first pinion. In a further embodiment (Fig. 5), the outer raceways are on the one ring 14 and the inner raceways on separate rings 15, 16, forced on to a ring 17 held on a pillar 6 1 by a screw 7. One of the rings 15 or 16 may be integral with the ring 17.

摘要： A regulator for a striking mechanism of a mechanical watch including a base, which can be assembled in a fixed manner with regard to the housing and which rotatably mounts a rotary wheel. At least two mass elements are arranged on the rotary wheel and by way of a rotation of the rotary wheel are deflectable radially outwards counter to a spring force on account of the centrifugal force, in order to regulate the rotation speed of the rotary wheel. At least three bearing elements are attached to the base, the bearing elements engaging peripherally on the rotary wheel, in order to mount this relative to the base.

摘要： In an electronic watch including a so-called automatic winding dynamo, structures of parts themselves and layout of the parts are improved to achieve a reduction in thickness of the electronic watch. Bearing portions for a rotational shaft (211) of a dynamo rotor (21) are made up of hole jewels (212, 214) and ring-shaped caps (213, 215). The cap (215) covers, from the outer side, one end surface (216) of the hole jewel (214) which locates on the side facing a dynamo rotor (21), and defines a lubricant holding annular slot (G3) between the cap and an outer circumferential surface of the rotational shaft (211). Accordingly, even with the dynamo rotor (21) rotating at a high speed, a lubricant is prevented from scattering to the surroundings from the annular slot (G3). Spacings between adjacent parts can be narrowed and the thickness of the electronic watch can be reduced.

摘要： An electromagnetic device for maintaining movement of an oscillating or rotating piece, such as the balance wheel of a timepiece, comprises a driving coil associated with a magnet on the piece. A contactor transistor in the feed circuit of the driving coil is controlled by a pick-up coil to deliver driving pulses to the driving coil. A regulating transistor acts on the contactor transistor to adjust the values of the driving pulses as a function of the desired speed of the piece. The emitter-base junction of the regulating transistor is connected to the terminals of the pick up coil and the regulating transistor is connected by its collector and its base to by-pass the baseemitter junction of the contactor transistor.
