Abstract: A gage that measures the size and out of roundness of the inside and outside diameters of ring-shaped parts comprises a centerline hub body together with a free style swing gage. The centerline hub body has extensible jaws that can be adjusted to position the body within the central opening of the part. A vertically protruding cylindrical post is located at the center of the hub body and is adapted to interface with the free style swing gage. The free style swing gage comprises a pair of parallel cylindrical rods that are adapted to fit over the centerline post. On each end of parallel rods is disposed a block, each block having a probe that protrudes downward from the block and is operable to contact a surface of the part to be checked. A front block is associated with a dial indicator connected with the probe to indicate any deviations in size or diameter of the part to be checked. The free style swing gage, together with the centerline post of the centerline hub body, allows the gage to be positioned at the actual centerline of the part. The free style swing gage is easily rotatable throughout the full 360 degree circumference of the part to be checked by grasping and rotating a handle on the rear block.

Abstract translation: 测量环形部件的内径和外径的尺寸和圆度的量具包括中心线毂体和自由式摆动量规。 中心线毂体具有可扩张的钳口，可以调整身体位置，使身体位于零件的中心开口内。 一个垂直突出的圆柱形柱体位于轮毂体的中心，并适于与自由式摆动量规相接合。 自由式摆动量规包括一对平行的圆柱形杆，其适于装配在中心线柱上。 在平行杆的每个端部设置有块，每个块具有从块向下突出的探针，并且可操作以接触待检查部件的表面。 前挡块与与探头连接的表盘指示器相关联，以指示要检查的零件的尺寸或直径的任何偏差。 自由式旋转量规与中心线毂体的中心线柱一起允许将量具定位在零件的实际中心线上。 通过抓握和旋转后挡块上的手柄，自由式摆动量规可以容易地旋转穿过零件的整个360度圆周进行检查。
