The utility model relates to an industrial robot power pack reliability test platform belongs to a reliability test device. By three comprehensive test box, power pack, the radial force loading unit, universal joint coupling, the moment of torsion loading unit is constituteed, and wherein power pack and radial force loading unit are laid inside three comprehensive test box, and the moment of torsion loading unit passes through universal joint coupling and is connected with power pack. The advantage can be simulated industrial robot's power pack's operating condition and carry out reliability test, power pack is located three comprehensive test box, can realize the temperature to power pack, humidity, exerting of load such as vibration, thereby simulation industrial robot power pack's actual environment operating mode, higher test efficiency has, and the automation is high, can gather in real time, calculate the power pack vibration, the temperature, transmission efficiency, the power consumption isoparametric, the driving error that can be used to the reduction gear, the return difference, the tooth clearance detects.
