ABSTRACT:
A fastener/shaft locking and adjustment apparatus and locking system which precisely positions, positively locks and avoids slippage of a positive locking nut along an elongated element. The positive locking nut includes a locking spline, an outer knurled cylinder, a rotatable spline, a return spring and a threaded nut. The locking spline includes a key member extending into the passage thereof which is engaged in the channel of the elongated element such that the locking spline does not rotate with respect to the elongated element. The locking spline further includes a first gear along an outer surface thereof which is capable of meshing engagement with a second gear provided along an inner circumferential cavity of the rotatable spline to lock the locking nut at its desired position along the elongated element. In order to adjust the position of the locking nut along the elongated element, the outer knurled cylinder, which is rotatable with the rotatable spline, is merely pushed and pulled to disengage the first gear from the second gear. The return spring is provided in the space surrounding the main body member of the locking spline for normally biasing the outer knurled cylinder in a locked position so that the first and second gears are normally biased in their engaged position to lock the locking nut along the elongated element. In order to precisely position the locking nut along the elongated element, a plurality of vernier marks are provided on an outward face of the outer knurled cylinder. A fixed notch extends along the length of a main body portion of the locking spline which acts as a reference point to align with the desired vernier mark of the plurality of vernier marks upon rotation of the outer knurled cylinder to precisely position the locking nut relative to the elongated element.
