The present invention relates to a test apparatus for planetary gear boxes. According to the present invention, a coupling drum (30) mutually connecting a planetary gear box on operation side with a planetary gear box on load side is installed, and a center shaft (Sc) to transmit rotation at a driving motor (M) to a sun gear of the planetary gear on operation side transmits power to the planetary gear box on operation side. The gear train box on operation side (40) to support multiple gears (Ga,Gc,Gd) including the gear (Ga) connected with the center shaft of the sun gear of the planetary gear box on load side is connected with a hydraulic cylinder provided with a piston rod moving by hydraulic pressure and connected to a bed allowing rotation. Through an interlocking shaft that is interlocked with an outermost gear of the gear train box on operation side, a gear train box (90) wherein multiple gears including the gear supported by the center shaft (120) are supported inside is connected. And a torque meter capable of measuring torque and number of revolutions is installed on the center shaft (Sc). |
