Shockproof bearing for horological piece, has guiding unit to guide force of bearing bush to displace bush uniquely and axially against axial action exerted by elastic arm during radial displacement of pivot

摘要

The bearing (1) has a bearing bush (16) mounted in a bearing body (4) and formed with a hole (20) to receive a pivot (2). An elastic arm (19) axially acts on the bearing bush. A guiding unit guides force of the bearing bush to displace the bearing bush uniquely and axially against an axial action exerted by the elastic arm during radial displacement of the pivot. The guiding unit is constituted by the elastic arm, where the elastic arm extends from periphery of the bearing bush toward periphery of the bearing. The bush is made of silicium material.
