  • Publication number: 20190337554
    Abstract: An electric power steering system includes: a housing defining a receiving space therein; a worm shaft disposed in the receiving space to be engaged with a worm wheel; a tilt plug coupled to an inner surface of the housing to be fastened to a predetermined position, and coupled to the worm shaft which is inserted into the receiving space to support the worm shaft; and an elastic supporter which is installed to the housing to elastically support the tilt plug toward the worm wheel. The tilt plug is provided with a coupling protrusion which is protruded from an end portion of the tilt plug in a center axis of the tilt plug and slides into an inner surface of the housing, and the inner surface of the housing is provided with a coupling indentation into which the coupling protrusion slides to restrict rotation of the tilt plug.

  • Patent number: 9321477
    Abstract: A rack bar support device supports a rack bar of a steering device of a vehicle toward a pinion shaft, and includes a rack bearing which is disposed opposite the pinion to contact the rack bar and a biasing assembly providing a force of pushing the rack bearing along a biasing axis toward the rack bar to urge the rack bearing to push the rack bar is engaged with the pinion shaft. The biasing assembly includes an adjustment plug, an adjustment assembly and a support plate assembly. The support plate assembly includes a support plate which is movably disposed between the adjustment member and the rack bearing in a state of being supported by the adjustment member, and a gap is formed between the support plate and the rack bearing.

  • Patent number: 8420880
    Abstract: A nuclear chemistry laboratory adopts In-site Cutting Technique to remove the large-scale glove box contaminated by transuranium compounds. During removal operation, to prevent further spreading of contamination, it is necessary to build an alpha airtight quarantine tent around the glove box that is ready to be cut. Each section of the quarantine tent maintains a stable airflow and sufficient air exchange to meet negative pressure requirements and effectively prevent leak of ? contamination. It is necessary to install a negative pressure ventilation system to assure the operation of the quarantine tent that has a pressure gradient and allows airflow from low contamination area to high contamination area to effectively prevent spreading of ? contamination and also increase the safety for the transuranium contaminated glove box that is not in service.
