introduction：The string shaft faults in the field are manifested by the string movement of the input shaft。Causes string axes There are two main aspects，①The string axis occurs because the broken tooth causes the input axis to lose axial constraint；②Is the intermediate shaft of the driven gear and shaft fastening is not strong。In the actual transmission，Often, the interference between the driven gear and the intermediate shaft is not enough，The driven gear generates axial serial movement with the intermediate shaft，And then the input axis occurs axial series。therefore，Insufficient interference is the main reason for the series shaft of the reducer。In addition，The steering of the reducer also has a certain effect on the string shaft。
