PUMP ASSEMBLY WITH RADIAL CLUTCH FOR USE IN POWER TRANSMISSION ASSEMBLIES

摘要

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