Abstract
Disclosed is a fault simulation experiment device of a windmill driving chain. The device is characterized by comprising a power motor (00). The power motor (00) is transmitted to a main shaft (02) via a speed reducer (01) and a first coupling. The main shaft carries out transmission to a gear case (06) via a second coupling (04). Output of the gear case (06) is transmitted to a motor (09) via a diaphragm coupling (07). The motor is in external connection with a load (10). The speed reducer allows the power motor to decelerate to have a rotating speed ranging from 2 to 20 rpm. The main shaft is supported by a single main bearing (03). A low speed shaft of the gear case is connected with the main shaft. A high speed shaft is connected with an electric generator by using the diaphragm coupling. The load is connected with the output end of the electric generator through conducting wires.
