Cutting disk mounting assembly

摘要

A cutting disk mounting assembly includes opposing end plates with a stub shaft attached to an exterior surface of one end plate. The plates have a first axial bore formed in the interior surface of the one plate and a protruding axial hub formed on the interior surface of the other plate. The hub is sized to fit in the first bore so as to align the plates in a clamping relation with their interior surfaces located adjacent to one another. A second axial bore is formed through the other plate and the axial hub thereon and a third axial bore is formed through the one plate so as to open into the first bore therein. The third bore aligns with the second bore when the hub is fitted in the first bore. Also, the third bore contains threads which threadably interengage with a threaded fastening screw when the latter is applied through the second bore to attach the aligned plates together in the clamping relation with respect to a cutting disk when the latter is disposed therebetween. The mounting assembly employs a pair of resiliently-flexible O-rings for gripping the cutting disk, and has a pair of continuous grooves defined in the interior surfaces of the plates adjacent the peripheral edges thereof. The grooves retain the O-rings such that they project from the grooves and beyond the respective interior surfaces of the plates so as to resiliently engage and grip opposite sides of the cutting disk.
