Abstract
A borehole televiewer apparatus includes a housing section having a cavity for the disposition of an acoustic signal transmitting and receiving transducer. An elongated threaded rod is disposed in the cavity and held stationary relative to the housing and supports a nut, a slipring assembly, the transducer and a drive motor assembly for axially translating the transducer and rotating the transducer while precluding rotation of the motor and a support plate therefor relative to the rod. The support plate is keyed to the rod by an elongated key and keyway configuration to prevent rotation of the motor and the support plate while permitting axial translation of the motor and support plate along the rod.
