SAW ARBOR WITH SPLINED MANDREL AND MATING, TIMED INTERNALLY AND EXTERNALLY SPLINED SAW BLADE MOUNTING SLEEVE

摘要

A saw arbor formed of a mandrel and a cylindrically apertured sleeve. Radially spaced splines are provided around the mandrel's outer circumference and around the inner circumference of the sleeve aperture. The mandrel splines and the sleeve aperture splines are shaped and sized for slidable mating engagement of the mandrel splines with the aperture splines. Radially spaced splines are also provided around the sleeve's outer circumference. The sleeve outer circumference splines are shaped and sized for slidable mating engagement with further splines spaced radially around a saw blade eye. Equal numbers of equally spaced involute splines are preferably provided around the mandrel, around the inner circumference of the sleeve aperture and around the sleeve's outer circumference. The splines can be formed to achieve 0.001" tolerance engagement between the mandrel and the sleeve, and between the sleeve's outer circumference and the saw blade eye, thus providing a high precision cutting unit.
