A tooling system includes a dipper having a lip with a plurality of apertures, the apertures extending at least partially through the lip. The tooling system also includes a modular adapter configured to be inserted partially into one of the apertures along an axis of insertion. The adapter is configured to be releasably coupled to the lip. The adapter includes a first portion configured to extend into the aperture, and a second portion configured to extend out of the aperture. The tooling system also includes a locking system including a fastener configured to extend at least partially into the aperture and couple to the adapter to the lip.

Modular ground engagement tooling system

A ground engaging tool locking system includes a pin having a first, proximal head region and a second, distal end region spaced from the first, proximal head region along an axis. The pin includes a groove located between the first, proximal head region and the second, distal end region. A biasing element is disposed at least partially within the groove.

A mining machine includes a frame having a guide rail, the guide rail having a central portion. The mining machine also includes a shoe having a recessed area that defines a roller path, the shoe further having a drive lug, wherein the central portion of the guide rail is configured to be disposed within the recessed area. The mining machine also includes a cutting tool coupled to the frame and positioned such that the cutting tool is configured to abrasively remove material from the drive lug as the drive lug passes by the cutting tool.

Methods and systems for detecting heavy machine wear. One system includes a heavy machine tooth of an industrial machine having a working end and a mounting end opposite the working end. The system also includes a wear indicator included in the tooth. The wear indicator includes a conductive tip, a conductive outer body extending along at least a length of the tooth, a conductive inner core positioned within the outer body, and insulating material positioned between the outer body and the inner core. The conductive tip is positioned between the working end of the tooth and the outer body and electrically couples the outer body and the inner core to form an electric circuit. The system also includes a transmitter included in the tooth. The transmitter transmits a state of the electric circuit.

A damper for dampening rotation of a dipper door relative to a dipper body of a mining shovel includes a shaft, an arm, and a high pressure fluid seal. The shaft supported for rotation about a shaft axis, and rotation of the shaft is dampened by fluid in an enclosed chamber. The high pressure fluid seal engages an outer surface of the shaft at a position between the first end of the shaft and the second end of the shaft. The high pressure fluid seal engages an outer surface of the shaft and includes a low pressure side and a high pressure side adjacent a shaft cavity. The arm includes a first end coupled to the first end of the shaft, and a second end coupled to the dipper door or the dipper body such that rotation of the dipper door drives the arm to rotate the shaft.

A method of controlling a variable geometry turbocharger is provided. A predefined desired boost pressure of a turbocharger is obtained from a memory. A predefined desired mass flow rate in an intake manifold of an engine is obtained from the memory. A theoretical amount of power required by the turbocharger to generate the desired boost pressure and the desired mass flow rate is calculated. An actual mass flow rate in the intake manifold is determined. An actual amount of power required by the turbocharger to generate the desired boost pressure and the actual mass flow rate is calculated. At least one adjustable vane of the turbine of the turbocharger is adjusted to allow the theoretical amount of power required of the turbocharger to generally equal the actual amount of power by adjusting the boost pressure.

Turbocharger control

A method for controlling fuel injection timing into a cylinder of an internal combustion engine having an internal control system based on ignition delay correlation wherein intake manifold pressure and oxygen concentration values are compared to steady state values of manifold pressure and oxygen concentration of a particular indicated torque set-point and engine speed. Comparing intake manifold pressure and oxygen concentration to steady state reference values further comprises experimentally determining exponential factors for intake manifold pressure factor and oxygen concentration factors. A multiplier for intake manifold pressure and oxygen concentration is determined taking into consideration the exponential factors for manifold pressure and oxygen concentration. An equation for correlation ignition delay is used to determine optional SOI timing.
