ZSN SERIES INTELLIGENT DOUBLE-FLANK INTERNAL GEAR ROLL TESTER

ZSN series intelligent double-flank internal gear roll tester is a double-flank instrument for internal gears. lt is developed by Harbin Zhida according to user requirements on the basis of our JSN series products. lt adopts the computerized numerical control (CNC) technology and is capable of automatic acquisition and intelligent processing of the measuring data. lt automatically measures the total radial composite deviation Fi" , tooth-to-tooth radial composite deviation f" and runout Fr" . In center distance deviation mode, it can measure upper and lower deviations of the center distance variation (Eas, Eai), two-ball measurement (M), and base tangent length (W), which affect gear backlash. Additionally, it can quickly obtain the location and magnitude of burrs, enabling online deburring processes.
