摘要： A non-contact measuring method and apparatus for producing a signal representative of a distance between facing surfaces of first and second parts, which are closely spaced apart such as the rotor and stator of an electric rotating machine. The method resides in positioning a sensor on the surface of the first part. The sensor includes first and second parallel, superimposed conductive plates electrically insulated from one another. The second plate is located in between the first plate and the surface of the first part. The first plate is fed with a high frequency signal through a resistance. A high impedance, low input capacity, unitary gain voltage amplifier is fed with the high frequency signal through the resistance. The second plate is fed with an output signal of the amplifier. The output signal of the amplifier is directly proportional to the distance between the two surfaces.

摘要： A device for measuring wear in large roller bearings that have two bearing rings (1 & 2) with space accommodating the rollers (3) between them. The device has an indicator that indicates a prescribed deflection between the rings and a probe (9) that is accommodated in an opening (10) in the outer bearing ring (2) with the end (11) of the probe able to come into contact with one of the surfaces of the inner bearing ring (1). The object is a device that will provide accurate and reliable indications of bearing wear even after years of use, that will be simple in design, and that cannot be damaged or destroyed by outside forces. The inner bearing ring accordingly has a groove (12) facing the probe, and the end of the probe extends into the groove. The surfaces of the groove are as far from the end of the probe as the maximal permissible depth of the wear on the bearing.

摘要： A machine such as a centrifugal pump has a rotating impeller which may get out of alignment if there is bearing wear or if the impeller becomes loose on its supporting axle. A misalignment sensing probe and switch may be installed through the housing of the pump with it probe tip in close proximity to the impeller's face. If the rotating impeller migrates out of alignment it will abrade the tip of the sensing probe. Inside the probe body there is secured a stranded insulated electrical conductor with one of its ends in the tip while the other end extends beyond the other end of the body and is connected into an electrical circuit. Abrasion of the tip will force contact between the stranded electrical conductor wire and the body of the probe. This closing of the switch will activate the electrical circuit which has been designed to shut down the power source and/or activate an alarm and thus avoid destruction of the pump.

摘要： A canned motor pump has a bearing wear sensing device comprising a pair of ring elements having opposing surfaces. The outer element is mounted fixed with respect to the stator and the inner element is mounted for rotation with the rotor. The outer, fixed element is coated with polytetrafluoroethylene. An ohmmeter measures the resistance between the elements through the coating. As the motor bearings wear, displacement of the rotating element causes wear of the coating which reduces its thickness and decreases the resistance between the sensing elements through the coating. One conductor of the ohmmeter is connected directly to the outer, fixed element, and the other ohmmeter conductor is connected through the conductive bearings to the rotating element. Thus, the ohmmeter can dynamically measure the motor bearing wear.
