A method of measuring contrate involute errors of double gears, gear shapers and gear shavers on the CZ450 gear integratederror tester using the polar coordinate method is introduced.
It was proved in practical measurement experiments that the principle of measuring gear integratederror with a small pressure Angle measurement worm was correct and the technology was possible.
