METHOD OF MEASURING THE DEVIATION OF KEY SLOT FROM PARALLELISM RELATIVE TO AXIS OF BASE SURFACE Russian patent published in 1997 - IPC

Abstract RU 2091700 C1

FIELD: measuring equipment. SUBSTANCE: object 2 under test is installed with base cylindrical surface on prism 1. Bisector surface of prism 1 includes comparison surface 3. Object 2 under test is rotated around axis Y-Y till point 8 of side surface of key slot touches rest 4. Distance from point 9 of contact of feeler gauge 7 with side surface of key slot to comparison surface 3 is measured, and deviation from parallelism is found by difference between preset a₁ and measured a₂ distances. EFFECT: high efficiency of measurements. 1 dwg
