Title: Grinding Wheel System

Abstract

A grinding wheel system includes a grinding wheel with at least one embedded sensor. The system also includes an adapter disk containing electronics that process signals produced by each embedded sensor and that transmits sensor information to a data processing platform for further processing of the transmitted information.

  • A grinding wheel system includes a grinding wheel with at least one embedded sensor. The system also includes an adapter disk containing electronics that process signals produced by each embedded sensor and that transmits sensor information to a data processing platform for further processing of the transmitted information.
  • A precisely machined metal ball is supported at a reference position on a numerically controlled grinding machine. The ball is displaceably carried by a metal holder having a conical shaped seat machined to support the ball. The holder is mounted at the reference position on the machine by means of a phenolic support to attenuate extraneous ultrasonic vibrations induced in the machine base. A piezoelectric crystal is acoustically coupled to the ball holder to sense ultrasonic vibrations induced in the ball and transmitted through the holder when the grinding wheel touches the reference ball. The ultrasonic frequency electrical signal outputmore » of the crystal is sensed by an ultrasonic detection circuit which produces a dc output signal having an amplitude proportional to the ultrasonic signal amplitude. The dc signal may be used to signal the numerical controller to stop the grinding wheel positioning mechanism when a predetermined level dc signal is sensed to indicate that the grinding wheel is positioned at the reference point along the axis.

  • An independent wheel suspension system is described for a vehicle having an engine adapted to provide a driving torque, a chassis, vehicle support means for resiliently supporting the chassis for displacement relative to a driving surface, and a wheel assembly for each wheel having a vertical center plane through the center thereof and a wheel axis substantially perpendicular to the vertical center plane. The wheel assembly has a chamber angle relative to the vertical center plane adapted to undergo a change of chamber as the wheel assembly undergoes movement relative to the vertical center plane. The independent wheel suspension systemmore » comprises: differential means comprising a differential housing, a differential input at an engine end of the differential housing adapted to be coupled to the engine so as to receive the driving torque therefrom about a differential input axis. The differential housing has a pair of lateral sides on opposite sides of the differential input axis, each lateral side having a differential output axis therethrough. The differential means is adapted to redirect the driving torque from the differential input axis to the differential output axis and is supported by the vehicle support means to position the differential input axis substantially perpendicular to the wheel axis.« less
  • A grinding assembly for grinding a weld joint of a workpiece includes a grinder apparatus, a grinder apparatus includes a grinding wheel configured to grind the weld joint, a member configured to receive the grinding wheel, the member being configured to be removably attached to the grinder apparatus, and a sensor assembly configured to detect a contact between the grinding wheel and the workpiece. The grinding assembly also includes a processing circuitry in communication with the grinder apparatus and configured to control operations of the grinder apparatus, the processing circuitry configured to receive weld defect information of the weld jointmore » from an inspection assembly to create a contour grinding profile to grind the weld joint in a predetermined shape based on the received weld defect information, and a manipulator having an end configured to carry the grinder apparatus, the manipulator further configured to operate in multiple dimensions.« less
  • For a transmission system, for a vehicle with at least four wheels, comprising a main transmission system which can be set to any one of speed stages, and a transfer transmission system which receives power from the main transmission system and can be selectively set either to a two wheel drive operational mode in which it provides transmission of power only to two wheels of the vehicle or to a four wheel drive operational mode in which it provides transmission of power to four wheels of the vehicle: a transmission control system is described which consists of: (a) means formore » detecting at least one parameter representing the operational condition of the vehicle; (b) a means for determining the operational mode of the transfer transmission system between the two wheel drive operational mode and the four wheel driver operational mode; and (c) a means for setting the main transmission system to selected ones of the plurality of speed stages thereof according to the parameter representing the operational condition of the vehicle as detected by the detecting means therefor, and according to the operational mode of the transfer transmission system as determined by the determining means therefore, a pattern of shifting between the plurality of speed stages of the main transmission system as the parameter varies varying according as the transfer transmission system is set to the two wheel drive operational mode or the four wheel drive operational mode.« less
