Device for pivoting an arbour in a time piece
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（中）：

用于在钟表中枢转心轴（11）的装置包括每个形成心轴的一端的两个枢轴（12,12'; 32）和用于接收两个枢轴的两个轴承。 每个枢轴包括大致圆柱形部分（19,19'; 39）和凸出的圆形部分（13,13'; 33），其延伸近似圆柱形部分并且在端部的方向上逐渐减小。 每个轴承包括弹性地保持在适当位置的枢转结构（25; 35），其包括由所述枢轴中的一个的所述近似圆柱形部分（19,19'; 39）穿过的近似圆柱形的通道。 枢转结构还包括轴承表面，所述枢轴的端部将与所述轴承表面抵接。 枢转装置的特征在于，每个轴承的枢转结构包括具有倒三角形或梯形轮廓（16,16'; 38; 46）的一部分的孔（16,16'; 36; 46），以及 因为两个枢轴中的一个的凸形圆形部分（13,13'; 33）用于抵靠所述倾斜内壁，使得心轴（11）轴向保持在两个轴承的孔的倾斜壁之间。
