The utility model discloses a vibration measuring device for a transmission chain slip ring of a wind generating set, which comprises three fixing rings, a sensor fixing seat and an acceleration sensor, and is characterized in that the fixing rings are respectively sleeved on the peripheries of an oil slip ring, a heavy-load wire harness interface and an encoder of the slip ring; the size of each fixing ring is matched with the size of the corresponding mounting position, two vibration measuring points are arranged on the outer circumferential surface of each fixing ring, a sensor fixing seat is arranged on each vibration measuring point, an acceleration sensor is mounted on each sensor fixing seat, and the acceleration sensor is connected with the vibration measuring points. And each acceleration sensor is connected with a main control system of the wind generating set through a cable. According to the utility model, a plurality of measuring points on the slip ring can be measured at the same time in the ope
