双半外圈调心滚子轴承外球面直径尺寸的测量

Measurement on diameter dimension of outer spherical surface for self-aligning roller bearing with double-half outer ring

用夹紧装置将两半外圈固定,形成一完整外圈,根据三点确定一个圆的原理,用调心机测量调心滚子轴承外球面直径尺寸。

With clamping device two half outer rings were fixed together to form a complete one.A diameter measuring instrument was used to measure the diameter dimension of outer spherical surface for self-aligning roller bearings according to the principle that there was one circle determined by three points out of a line.
