PROBLEM TO BE SOLVED: To provide a speed-increasing machine system capable of more sufficiently acquiring a rotation number of a speed-increasing machine of a wind power generation device.SOLUTION: A speed-increasing machine system is provided to a wind power generation device 1. The speed-increasing system comprises: an oil level gauge 30 for measuring oil level height of lubrication oil of a speed-increasing machine 10; and a monitoring device 114 for associating the oil level height measured by the oil level gauge 30 with an output rotation number Nout of the speed-increasing machine 10. The monitoring device 114 diagnoses a status of the speed-increasing machine 10 based on the output rotation number Nout acquired from the measured oil level height. Diagnosis of the status of the speed-increasing machine 10 includes determination about failure. |
