The invention discloses a bearing-gear multi-fault coupled simulation experiment table, which comprises a first direct-current adjustable speed motor and an input shaft which passes through a gear boxbody and is connected with the first direct-current adjustable speed motor. The input shaft is connected with a transmission shaft of a bearing box body, a mandrel of the bearing box body is providedwith a replaceable bearing housing, one side of the replaceable bearing housing is provided with a tip and a top tray, the input shaft in the gear box body is sleeved with an input shaft shifting slide gear, a gear box middle shaft and a gear box output shaft which extends out of the gear box body and is connected with a second direct-current adjustable speed motor are also arranged in the gear box body, the gear box middle shaft is provided with a middle shaft pinion and a middle shaft gearwheel, and the gear box output shaft is provided with an output shaft shifting slide gear which is meshed with the middle shaft pinion. The experiment table not only can simulate respective fault rotating table, but also can synchronously simulate fault states of a bearing and a gear so that the faultcharacteristics are closer to the actual conditions on site, and the experimental study and production practice are combined more conveniently.
