Abstract
A torque limiting roller includes a shaft, a frictional unit, a roller assembly, a fixing unit and an elastic unit. The shaft includes a first end and a second end. The frictional unit is mounted on the first end of the shaft. The roller assembly is rotatably mounted on the shaft and includes a first end and a second end. The first end of the roller assembly is in frictional contact with the frictional unit. The fixing unit is mounted on the second end of the shaft. The elastic unit is mounted on the shaft, disposed between the fixing unit and the roller assembly, and contacts with the second end of the roller assembly and the fixing unit to provide a normal force between the roller assembly and the frictional unit and thus to provide limiting torque. A medium separating mechanism using the torque limiting roller is also disclosed.
