Abstract:
A power transmission device includes a rotatable shaft having an axis of rotation. A lubrication pump includes an inner rotor and an outer rotor in meshed engagement with one another. A clutch continuously drivingly couples one of the inner rotor and the outer rotor and the shaft to limit the power transferred from the shaft to the lubrication pump. The clutch includes a plurality of circumferentially spaced-apart protrusions biasedly engaged with the shaft.
