  • Patent number: 10781895
    Abstract: A device for tensioning, and facilitating removal and replacement of, the drive belt of an oilfield pumpjack. The device utilizes a regulated air supply, and includes an air driven actuator, namely an air bag, interposed between a base and a frame supporting an idler wheel and pivotally connected to the base, whereby providing air to the air actuator causes the frame to pivot relative to the base so as to the bring the idler wheel into belt-tensioning contact with the pumpjack belt. Evacuating air from the air actuator permits the idler wheel to move away from, and thus slacken, the belt, permitting removal and replacement of the belt.

  • Publication number: 20140238162
    Abstract: This invention refers to a speed reducer made up of a chain carrying nuts and of a screw, i.e., a ball screw in the case of the first embodiment, a roller screw in the second embodiment. The ball screw or the roller screw drives the nuts when these are aligned on one of the straight stretches of the chain. The ball screw, or the roller screw, can be almost as long as the distance between the centers of the output sprockets on which the chain is mounted; given these features and because the nuts wrap the ball screw, or the roller screw in a great surface, the load capacity is high. Given that in both embodiments the contact is rolling, friction is therefore low and as a consequence, efficiency is high, so high indeed that it allows this invention also to serve as an amplifier.

    Abstract: In accordance with one embodiment, a parabolic trough system is disclosed to capture solar heat. It has low mass, high rigidity and precise robust rotational control. The trough does not require massive supports, since it use a “sandwich structure” where the core is lightweight urethane foam and the skin is made of aluminum sheet. The inside skin also functions as the parabolic reflector. The shape minimizes wind loads by centering the receiver in the parabola and by making the center of focus the center of rotation. The system can be rapidly built in the field since there are few parts. Assembly does not require heavy equipment. Support posts are used on both sides of the trough to minimize the anchoring requirements in wind loads. The trough bodies are rotated in a rotational control mechanism that uses circumscribing rings to support a continuous row of troughs that can sustain 120 mile per hour winds. Optical performance is improved with the drive ring design.

    Abstract: A vibration damping device is described that dampens vibration produced during the conversion of rotational motion into reciprocal motion. The damping is performed using a simple structure wherein first and second conversion mechanisms are symmetrically arranged with respect to a plane of symmetry, first and second rotating shafts rotate opposite to each other at a constant speed, and the rotational motion is converted into reciprocal motion. The total of mass acting on gravity centers of a first balancer and a second balancer is approximately equal to the total of mass reciprocally driven by a first driving shaft and a second driving shaft. Both gravity centers are positioned 180 degrees to the first driving shaft and second driving shaft across the axes of the first rotating shaft and second rotating shaft. As a consequence, the forces in the direction of an axis can be balanced suppressing vibration.
