Abstract: Aiming at the current proldem of bevel gear tester was so low efficiency, single function and low accuracy that could not do a reasonable judgment, study was taken to research the measurement of geometry and performance of bevel gears. A bevel gear geometry and performance tester was designed out, which included mechanical structure, electrical control, and measurement software. Based on the compact design method, a compact and stable bed was designed out, meanwhile, two rotary movement with spindle motors and three linear axes which were close\|loop feedback with encoders were established. Siemens Simotion system was employed to control the motion and electrical components. While controlling the gears rolling, the information was collected and analyzed in the computer. The results indicate that the mechanic structure is capable of measuring 4th precision bevel gears, and through the transmission error, structure\|borne noise and grinding burn signals to get a reasonable judgment.

Key words: bevel gear measurement; high precision; mechanic design; electrical control
