A number of marine geared diesel engines have been widely used in recent years for the car ferries, the car carriers and the general cargo boats. As the reduction system for the engines, the epicyclic gear reducers have also been widely used because of their many advantages such as light-weight, compactness, concentricity of input and output shaft.<BR>IMT epicyclic gear reducers developed in our country utilizes two fundamental functions to balance the load on each gear. One is the oil film function of the floating intermediate rings between the planet gear and the planet gear shaft, and the other is spring function of the balance pins between the double internal gear and the internal gear retainer.<BR>A recent research of torsional vibration analysis of shafting system with IMT epicyclic gear reducer tells the IMT epicyclic gear reducer has a good chance of avoiding torsional vibration.
