Loading contact is to make a pair of detected gear simulation real load detect it by drive motor and loader to contact situation.Drive motor drives the rotation of driving gear rotating mechanism by synchronous band, and by the rotation that is meshed with driven gear of detected driving gear, drive driven gear rotating mechanism, torque rotary speed detector and loader load contact detection.Reciprocating mechanism can be adjusted driving gear mechanism and move up and down, and the distance detecting instrument can detect the distance that driving gear moves up and down up and down.Driving gear mechanism and driven gear mechanism move axially by axial moving mechanism (a, b), and its function is the gear that is fit to different sizes, and axially movable degree of accuracy is detected by the axial distance detector.
Beneficial effect of the present invention: the gear that can solve and verify coming of new under nominal load, the truth of working flank contact during gearing mesh.Do not conform to the Design Theory contact region when actual contact detects, can instruct manufacturing by detecting data.Be characterized in:
1) within the operating load 1000Nm of driven gear, can realize meshing contact detection under the multiple gear simulation real work load.
2) loader is stepless loading, and it is fit to the load of the gearing mesh of various different sizes.
3) distance of gear biasing adopts accurate screw pair adjustment, adopts advanced grating distance meter to measure.
4) can reach axial adjustment up and down, the gear dynamic that is suitable for varying in size loads contact detection.
