ARBOR AND CIRCULAR SAW WITH ASYMMETRIC SPLINE HAVING GENERALLY RADIAL FORCE-TRANSMITTING FACE
摘要
<p>An arbor is formed with uniformly-spaced splines each of which has a cross-section in the shape of an asymmetric trapezoid. The leading force transmitting face of each of the splines is disposed at an angle lagging by about seven degrees from a truly radially- extending plane of the arbor. The trailing face of each of the splines is disposed other than in a generally radially-extending plane of the arbor. A circular saw blade mounted on the arbor has a central opening or eye formed with complementarily shaped recesses such that the arbor splines fit within the recesses in the eye for transmission of torque from arbor to saw.</p>
