ACTUAL MEASUREMENT GAUGE FOR MEASURING A CENTER DISTANCE OF A ROTARY WHEEL OF A BALL BEARING, CAPABLE OF ACCURATELY MEASURING A DISTANCE BETWEEN CENTERS OF BALL BEARINGS IN A DIAMETER DIRECTION

摘要

PURPOSE: An actual measurement gauge for measuring a center distance of a rotary wheel of a ball bearing is provided to prevent assembly failure between an inner wheel and an outer wheel, size failure, and torque failure caused by processing errors of a bearing groove.;CONSTITUTION: An actual measurement gauge for measuring a center distance of a rotary wheel of a ball bearing comprises a base rod(110), a first position fixture, a second fixture, a size measuring member, and a second ball bearing. The base road has fixed length. The first and second position fixtures are mounted in the base rod to be faced each other, thereby being fixed. The size measuring member is composed of a sleeve being joined to the first position fixture, a thimble rotating on the sleeve, a spindle moving back and forth by the rotation of the thimble, a first bearing holder being mounted on a front end of the spindle, and a first ball bearing being mounted on the first ball bearing holder. The second ball bearing is mounted on a second ball bearing holder being joined to the second position fixture.;COPYRIGHT KIPO 2013
