Abstract
A liner for a flexible rotative drive shaft has a single tube with a multiplicity of spaced-apart, flared sections disposed along its elongated length. The flared sections serve many purposes, but primarily center the liner within an external aluminum tube that houses the flexible shaft and liner assembly. The flared sections also reduce non-uniform lubricant distribution along the drive shaft, longitudinal and radial vibration, and shock. Due to the use of flared sections, the overall weight of the liner is reduced, compared to conventional liners.
