Synchronous interface transmission structure of test bench

The utility model relates to a test bench synchronous interface transmission structure, including the driving motor drive gear that connects gradually, little drive gear, big drive gear, little separation gear, separate the gear down and separate the gear on, separate gear, transmission shaft gear greatly, its medium and small drive gear, big drive gear join in marriage the dress same axis altogether, separate the gear down and the dress same axis is joined in marriage to last separation gear to the connection isolation ware separates the gear greatly and still connects synchronous gear, and synchronous gear connects synchronous ware, the separator can drive down and separate gear and last separation gear axial motion, synchronous ware is provided with the end tooth, the end tooth cooperation that can set up with the synchronous gear terminal surface. The utility model provides the high stability and the reliability of helicopter main reducer test bench operation, but this type of structure wide application i
