Abstract: A tooth profile for a tooth of a high contact ratio spur gear, the tooth having an active profile, a root, and a tip, the active profile having a start adjacent to the root and having an end adjacent to the tip, includes a base tooth profile extending from the start of the active profile to an operating pitch area of the high contact ratio spur gear; and a modified base tooth profile, the modified base tooth profile being the base tooth profile modified by a profile relief curve, the modified base tooth profile extending from the operating pitch area to the end of the active profile, thereby yielding a long profile modification.

Abstract: A draft force sensor is provided for a coupling member coupled between a towing vehicle and a towed earth engaging implement, such as a scraper. The draft force sensor includes first and second bores extending through the coupling member. Each bore has a horizontal axis which extends perpendicular to a main fore-and-aft axis of the coupling member. The second bore is positioned above the first bore and spaced apart from the first bore. Each of the bores is surrounded by an outer cylindrical wall. Four electrical strain gauges are spaced apart and placed on the wall of each of the bores. A center line bisects an axis line which extends between the axes of the first and second bores. The axis of each bore is spaced apart from the center line by a distance which is less than a diameter of the bores. The strain gauges are connected electrically in a circuit which generates a draft force signal in response to draft forces applied to the coupling member.

Abstract: The adjustment mechanism of the present invention is mounted to a frame and comprises an alignment cam that is pivotally mounted to the frame by a tension link pivot pin. The alignment cam is provided with an actuating arm that is coupled to a longitudinally extendible adjusting member. The longitudinally extendible adjusting member comprising a screw jack. A tension link is pivotally mounted to the tension link pivot pin. Camming surfaces on the alignment cam are skewed with respect to the transverse axis defined by the tension link pivot pin so that rotation of the alignment cam twists the tension link and thereby the idler wheel predominately about a vertical axis. Albeit to a lesser degree, rotation of the alignment cam also twists the tension link and idler about a longitudinally extending horizontal axis. Therefore by extending or retracting the screw jack, the toe-in/toe-out orientation of the idler wheel can be adjusted.
