防震钟表轮
摘要：
本发明提供一种防震钟表轮(1)，用于驱动相对于所述轮(1)的枢轴线(D)具有非零不平衡量(B)的部件(4)，所述轮(1)一方面包括用于绕所述枢轴线(D)枢转地引导该轮的心轴(2)，另一方面包括布置或装配在所述轮(1)的轮缘(8)上的传动机构(7)，所述轮(1)包括位于所述心轴(2)与所述轮缘(8)之间的至少一个柔性件(9)。所述轮缘(8)包括圆柱形台肩(81)，其为对中目的与包含在所述心轴(2)中的互补圆柱形台肩(21)邻接配合，以确保所述传动机构(7)与所述心轴(2)完全同心。
摘要（英）：

The invention provides a shockproof timepiece wheel (1) for driving a component (4) having non-zero unbalance (B) relative to a pivot axis (D) of this wheel (1). This wheel (1) includes, on the one hand, an arbour (2) for pivotally guiding the wheel about this pivot axis (D), and on the other hand, a drive means (7) arranged or assembled on a flange (8) of this wheel (1), this wheel (1) includingat least one flexible element (9) between this arbour (2) and this flange (8). This flange (8) includes a cylindrical shoulder (81) cooperating in abutment for centring purposes with a complementary cylindrical shoulder (21) comprised in this arbour (2) to ensure the perfect concentricity of this drive means (7) with this arbour (2).
