The ultra precision master gear is used for the measure of ordinary precision gear entity reference and checking of gear measuring instrument

its own comprehensive deviation detection is of great significance

and the gear radialcomprehensive deviation measuring instrument at present cannot meet requirement.For this purpose

the special measuring instrument is developed

spring lamination suspension swing rack structure is adopted

the disadvantage of larger gear double meshes instrument rotary error

low sensitivity

low resolution and larger measuring force are overcome.The artificially intelligence of test system is realized.The accuracy of 2 and above of involute cylindrical gear radial comprehensive deviation ruling by GB/T 10095.2—2008 can be carried out.
