Double sided meshing comprehensive measuring instrument for disc gears

1、 Product Technical Overview

The JS1-20BT disc 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. The newly developed new generation of microcomputer controlled intelligent double meshing instrument adopts microcomputer numerical control and error data acquisition intelligent processing technology to automatically measure the radial comprehensive total deviation Fi ', one tooth radial comprehensive deviation fi' and radial runout Fr 'of gears, achieving rapid judgment of the quality condition of gears and quickly determining the size and location of tooth surface collision points for online maintenance.

2、 The core technology of the instrument

1. The standard gear eccentricity error correction function has been added to obtain national invention brick benefits, which can automatically correct the standard gear. By starting the automatic testing and correction function software, the instrument will automatically complete the measurement and correction of the standard gear 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. It is possible to accurately measure the cross bar distance (M) and common normal line (Wk) of the workpiece gear.
