    Abstract: A sealed generator housing has two components, one of which includes a circumferential bore having a cylindrical internal support surface, and the other of which has an end wall equipped with mounting segments, each of which has a mounting surface which contacts the support surface from within, centering the circumferential wall with respect to the end wall, while permitting relative axial sliding of the components. A gap is present between the two components, which permits such relative sliding due, for instance, to thermal expansion and contraction. An annular sealing member extends axially across the gap at the exterior of the housing and is entirely surrounded by a length-adjustable clamping strip exerting inwardly oriented pressure on the sealing element. The annular sealing element has bulges at its internal surface, such bulges being received in corresponding circumferential grooves of the two components of the housing extending alongside the gap. The annular sealing element is supported from within by support portions rigid with one of the components.

    Abstract: An explosion proof submersible gearmotor in which a gear reducer has a housing with a sealed chamber and input and output shafts with a gear train connecting the input and output shafts, and in which a sealed motor is mounted on the gear reducer housing and a wall of the gear reducer forms one end wall of the motor, the shaft of the motor being directly connected to the input shaft of the gear reducer. The chamber in the gear reducer contains a non-conducting lubricant, and a moisture-sensing probe extends in the lubricant in the chamber for sensing the presence of water and transmitting a signal in response thereto, indicating a failure in one or more seals of the gear reducer. The operation of the motor of the gear reducer is then either automatically or manually interrupted until the unit has been serviced and repaired.

    Abstract: A fire safety transmission apparatus comprising an explosion-proof container, an adapter plate secured to the container, a cylindrical sleeve mounted to the adapter plate defining a central bore, allowing communication with the interior of the container. The sleeve bore is stepped, defining seats for a plurality of ball bearing races mounted therein. A rotatable stepped shaft having a diameter adapted to fit within the central bore rests on the ball bearing races. The shaft is connected to a motor mounted in the explosion-proof container with the spacing defined between the inner wall of the cylindrical sleeve and the outer surface of the freely rotating shaft being sized a predetermined tolerance for a predetermined length sufficient to prevent a flame from passing therethrough.

    Abstract: A rotary electric machine in which a capacitor does not explode even if heat is generated in the capacitor, is provided. A heat sink includes a recess-shaped capacitor housing portion having an inner peripheral side surface joined to an outer peripheral side surface of a capacitor via a capacitor heat dissipation material, and the capacitor housing portion includes an explosion-proof valve recess located at a position facing an explosion-proof valve of the capacitor, and a communication passage providing communication between a drive circuit board and the explosion-proof valve.
