Double sided meshing comprehensive measuring instrument for shaft gears

1、 Product Technical Overview

The JS1-20AT shaft gear double-sided meshing comprehensive measuring instrument combines the design concept of advanced foreign double meshing instruments with the actual needs of gear manufacturers, based on the reference of early products. It is a newly developed new generation of microcomputer controlled intelligent double meshing instruments. This product adopts microcomputer numerical control and intelligent processing technology for error data acquisition, automatically completing the measurement of the variation of the gear's one turn center distance Fi ', one tooth center distance fi', and radial runout Fr; To achieve rapid assessment of the quality condition of gears, and to quickly determine the size and location of tooth surface collision points for online maintenance.

2、 The core technology of the instrument

1. Added the function of correcting the eccentricity error of standard gears that have obtained national invention brick benefits, which can automatically correct the standard gears. Activate the automatic testing and correction function software, and the instrument will automatically complete the measurement and correction of standard gears, and automatically store the correction data in the computer. Greatly improving the measurement accuracy and repeatability of the instrument, it solves the measurement error caused by the error of standard gears in traditional double meshing instruments during measurement.

2. Perform special data processing on the measured data to separate the small burrs and bumps caused by bumps from the "fi", accurately distinguishing between the radial comprehensive error of a tooth and the burrs and bumps

3、 Instrument measurement items and parameters

1. Radial comprehensive error: (Fi, fi);

2. Center distance variation; A

3. Radial jump: (Fr 〞);

4. Average span distance: (M);

5. Average common law length: (Wk)

4、 Main technical parameters of the instrument
