Measuring profile in two dimensions of articles such as crankshafts and camshafts by placing them in vertical bearings and using feeler gauge with spring assisted measurement in one dimension

摘要

The test piece (4) is held vertically between bearings (2,3) and may be rotated by a motor. Measurements are made by a finger (14) which may be moved vertically on a scale (26) and horizontally on a scale (21) with a horizontal adjustment (17) for spring loading (15). Initially measurements (RefA, RefB) are made to the two bearings and used to correct the profile measurements
