v调心球轴承有圆柱孔和圆锥孔两种结构，保持架的材质有钢质、合成树脂等。其特点是外圈滚道呈球面形，具有自动调心性，可以补偿不同心度的轴挠度造成的误差，但其内、外圈相对倾斜度不得超过3°。 vAdjusts the bulbus cordis bearing to have the column hole and the circular cone hole two kind of structures, retainer's material quality has the steel, the synthetic resin and so on. Its characteristic is the addendum circle roller conveyer assumes the ball face shape, has the automatic accent disposition, may compensate the error which the misalignment the axis amount of deflection creates, but among them, the addendum circle relative gradient do not surpass 3°.
