CONSTANT VELOCITY DRIVE FOR TILT ROTOR ASSEMBLY

摘要

A constant velocity drive includes a drive ring and a driven ring positioned around the drive ring. Drive links extend from the drive ring to the driven ring to transfer torque applied at the drive ring to the driven ring. Elastomeric bearings are positioned at the driven ring to transfer torque from a drive link of the plurality of drive links to the driven ring. Each elastomeric bearing includes both spherical bearing elements and planar bearing elements to allow for tilt of an axis of rotation of the driven ring with respect to an axis of rotation of the drive ring while ensuring a constant rotational velocity of the driven ring with respect to the rotational velocity of the drive ring.

1. A constant velocity drive comprising;
a drive ring having a drive ring axis of rotation; a driven ring disposed around the drive ring and which is driven by the drive ring to rotate about a driven ring axis of rotation; a plurality of drive links extending from the drive ring to the driven ring to transfer torque applied at the drive ring to the driven ring; and a plurality of elastomeric bearings, each elastomeric bearing disposed at the driven ring to transfer torque from one of the plurality of drive links to the driven ring, each elastomeric bearing including both spherical bearing elements and planar bearing elements to allow for tilt of the driven ring axis of rotation with respect to the drive ring axis of rotation while ensuring a constant rotational velocity of the driven ring with respect to the rotational velocity of the drive ring.
