Abstract
The concave adjust assembly uses a torsion axle connecting a drive to a concave. The torsion axle includes an inner element having an angular sectional shape, a tubular outer element disposed about the inner element and having a larger angular sectional shape oriented such that corners of the tubular element are disposed opposite flats of the inner element, the elements being laterally relatively rotatable, and damping elements disposed between the inner and outer elements such that the rotation will compressively load the damping elements. The drive includes a motor, such that operation of the motor will adjustably move the concave, and the damping elements will damp impulse loads generated from threshing, to reduce transmission of the loads to the drive.
