Abstract
The drive shaft assembly has a variable length. Each end of the drive shaft assembly has a flange for attaching to whatever is intend thereon such as a gear box drive or fan mount, and a female threaded attachment on the opposite side of the flange. A slide is secured in this attachment. The slide has a bore therein with longitudinal ball bearing races partially along the length of the wall. Each end of the shaft has opposing ball bearing races as compared to those in the slide and has further thereon an o-ring retainer. A sufficient number of ball bearings are placed in each race to allow for movement of the shaft in the slide. The o-ring is placed on the shaft after the bearings are inserted. After this the slide is secured to the flange.
