Abstract
A torque transfer assembly (30a, 30b, 30c) is assembled with reinforced fasteners (44) so that it may withstand the shear forces created by torque loads. The reinforcement is provided by surrounding the portion of a fastener subjected to shear stress with a sleeve-like tube key (40).
Claims18
A torque transfer assembly comprising:
- at least one disk member and a shaft,
- at least one fastener reinforced;
- and a tube key surrounding at least a portion of the fastener;
- wherein the disk member is mounted onto the shaft with the fastener and tube key

A method of driving an auger comprising the steps of:
- presenting a torque transfer assembly comprised of at least a first disk member and a second disk member attached to a shaft with reinforced fasteners;
- attaching the auger to the torque transfer assembly;
- rotating the first disk member in order to drive the auger.
A torque transfer assembly comprising:
- at least one sprocket mounted onto a shaft,
- at least one fastener reinforced with a tube key;
- wherein the sprocket is mounted onto the shaft with the reinforced fastener so that the tube key is positioned on a portion of the fastener that experiences shear stress.
A feed mixer comprising:
- a mixing tank;
- at least one top auger rotatably connected within the mixing tank;
- at least one bottom auger rotatably connected within the mixing tank so that it is
- positioned underneath the top auger and substantially parallel thereto;
- wherein at least one of the top and bottom augers is driven via a torque transfer assembly, comprising:
- at least one disk member and a shaft;
- at least one fastener reinforced;
- and a tube key surrounding at least a portion of the fastener;
- wherein the disk member is mounted onto the shaft with the fastener and tube key.
