The transmission of gears requires The continuous meshing of gears completes the transmission of motion. The accuracy of gear transmission mainly lies in the meshing accuracy between gears. Since the meshing accuracy of gears affects the accuracy of the entire gear transmission, it is related to the service life of mechanical equipment. Therefore, in gear production and processing It is necessary to test the meshing accuracy of the gears. Usually, the meshing tester is used to test the radial comprehensive error of the gears and the change of the center distance of the gear pair to determine whether the tested gears are qualified. The moving standard gear is meshed, and the radial variation of the standard gear is tested by the set dial gauge to detect the individual errors such as the radial runout of the gear ring and the tooth shape error of the gear under test. The maximum variation in the tooth is the radial comprehensive error and the radial comprehensive error of one tooth respectively. The maximum variation obtained from the paired measurement of a pair of measured gears is the change in the center distance of the gear pair, which is the maximum variation in the center distance of the gear pair. However, the conventional The meshing tester can only test the meshing accuracy of a single gear. In routine use, multiple gears are often assembled on the shaft to make a gear shaft or multiple gears are processed on one workpiece. The conventional meshing tester can only test a pair of gears. Therefore, it is not possible to directly test whether the gear shaft or multiple gear workpieces are qualified. If the unpredictable gear shaft is installed in the machine equipment, its service life will be reduced, and serious accidents will be caused.
