TORTIONAL CLEARANCE MEASURING APPARATUS FOR YOKE ASSEMBLY

摘要

The present invention provides a clearance measuring apparatus for a yoke assembly where a weld yoke connected to a first connection shaft and a clamp yoke connected to a second connection shaft are connected by a spider. The clearance measuring apparatus comprises: a first support part installed on a base to fix and support the first connection shaft; a second support part installed on the base to be adjacent to the first support part and supporting the second connection shaft to be rotated; a lever cap coupled to an end of the second connection shaft; a lever arm installed to be symmetrical on both sides of the lever cap; an indicator installed on one end of the lever arm to measure the location displacement value when the lever arm is rotated; and a weight kit selectively mounted on and separated from the one end and the other end of the lever arm. After the weight kit is mounted on one end of the lever arm to determine a zero point (a position) of the indicator, the weight kit is mounted on the other end of the lever arm to measure the linear distance (L2) where the indicator moves as far as possible from the zero point in a linear direction, and a torsional clearance of the clamp yoke with respect to the weld yoke can be computed using the measured distance (L2) and the distance (L1) from the rotation center of the lever arm to the indicator.
