Saw blades beveling is an advantageous capability to be included with power saw assemblies, such as table saw assemblies which include a saw assembly comprising a saw blade, extending through a planar surface (table), coupled with a motor by a mounting assembly. Beveling assemblies, provide the operator of a table saw with the ability to adjust the angular presentation of the saw blade relative to the planar surface of the table. Unfortunately, many beveling assemblies included with table saw assemblies, and the like, are limited in the capabilities they may provide to the operator.
A typical limitation of many beveling assemblies is the enablement of beveling in a single tilt orientation. For instance, a beveling assembly may provide the operator with the ability to adjust the angular presentation of the saw blade relative to the planar surface of the table in a right tilt orientation or a left tilt orientation. Other beveling assemblies have limited beveling capabilities resulting from unwanted contact between the component features of the saw assembly or beveling assembly and other structural impediments of the table saw assembly, such as the unwanted contact between the motor, which drives the saw blade of the table saw assembly, and the underside of the planar surface of the table or structural support features of the table saw assembly. Additionally, unwanted contact may result from contact between the mounting assembly of the saw blade and the table. For instance, when the blade is beveled, the mounting assembly may contact the underside of the table because of the mounting assembly's proximate location to the table.
Unfortunately, attempts to resolve these problems have resulted in assemblies which may require a user to accept limited capabilities. For example, unwanted contact is decreased, but only by limiting the depth of cut capabilities of the saw blade of the table saw assembly. Therefore, it would be desirable to provide a table saw assembly which enables the saw blade with bi-directional beveling capabilities (right and left tilt orientation) without reducing the capabilities of the saw blade due to factors, such as unwanted structural impedance.
Additional limitations may be a result of design limitations. For instance, the assembly, which couples the saw blade with the motor of the table saw, typically, statically fixes the position of the motor relative to the saw blade. Such a situation may result in decreased performance of the saw assembly during beveling due to changes in tolerances resulting from changes in the positions of these features due to beveling.
Therefore, it would be desirable to provide a beveling assembly which increased the ability of the component features of the table saw assembly to remain near optimal tolerances during the beveling of the saw blade. Another design limitation is the typical arbor assembly is enabled as a single axle, which may be limited to coupling with the saw blade to impart angular momentum on a single end of the axle. This may result in the beveling assembly enabled with the single axle arbor assembly limiting its capabilities to a single tilt orientation, as described previously. Still further, this may result in increased time spent attempting to properly re-align the single axle arbor assembly when transitioning between beveling in a first tilt orientation to beveling in a second tilt orientation, such as from right to left. This may significantly decrease productivity accomplished through use of the table saw employing such a single axle arbor assembly. Further, due to such drastic re-positioning required by the single axle arbor assembly there may be an increase in tolerance misalignments resulting in increases in non-production time spent by the power tool. Therefore, it would be desirable to provide an arbor assembly which decreased time spent re-aligning the arbor assembly and increased the ease of employing the saw blade on the arbor assembly for beveling in both tilt orientations.
Further, it is common practice in the field of power tools, particularly arbor assemblies for table saws, to take steps to “true” the assembly after it has been assembled. This truing may assist in increasing the productivity and life span of the power tool by assisting in reducing wear to the component features of the power tool. Steps, such as machining the flange may true the arbor assembly and may decrease the amount of “wobble” introduced into the saw blade during operation of the table saw. Unfortunately, after the truing of the arbor assembly is complete the parts of the arbor assembly, such as the bearing for example, may wear out due to use, requiring replacement. It is known to allow for the operator to disassemble the arbor assembly in order to replace the bearing. This often requires removal of the flange in order to access the bearing. It is typically the case that when the operator re-assembles the arbor assembly the flange and possibly other component features are no longer in the trued position, as originally provided by the manufacturer. Thus, “wobble” may be introduced into the spinning blade of the table saw. Therefore, it would be further desirable to provide an arbor assembly which assists the operator in maintaining its trued position even after replacement of component features of the arbor assembly.
