#$%^&*AU2011232738B220160414.pdf#####Reduced Mass High Speed Doffer Column with Improved Shaft Preload 5 Abstract of the Disclosure A light-weight upright shaft (14) supports cotton harvester doffers (12). An internally threaded mounting end (36) receives a bolt (38) which is stretchable to a greater degree than the shaft to provide a reliable shaft preload condition that 10 prevents the doffers from spinning relative to the shaft. The shaft may be hollow and may have a diameter greater than conventional shafts to reduce weight and increase the stiffness and thereby increase critical speed. The preload structure does not require a nut and has increased thread engagement compared to previously available structures. 1532 1/2 1022 22 12k 2 2614 FIG. 1 16 14L 28 --- ~-2 30 -15 38 -
