Cone coupling is one of the fixing mechanical elements between a boss and a shaft. It has been extensively applied to the transmitting system of torque which has many fluctuations such as diesel engines, instead of the well-known key coupling. The objective of the present investigation is to clarify the mechanism of demounting the boss from the shaft when repair is required. The conventionally adopted method of demounting the boss from the shaft is to pour oil into the contacting surface through an oil groove which is premachined on the contacting surface of cone coupling. Normal contacting stress distributions were calculated by a finite element method (FEM) for symmetrical elastostatic contact problems. Demounting experiments were performed employing an S45C boss and shaft and Morse taper No. As a result, it was found that the demounting pressures could be achieved by assuming an equilibrium between the frictional force acting on the contacting surface and the thrust force. We obtained fundamental data about demounting for the cone coupling.
