<b>Flexible Shaft Coupling for 4" B/W, Hurth - 5HP/100RPM Capacity</b> <br /> <br />The R&D Flexible Couplings are fabricated from a contoured flexible disc molded in tough yet resilient new type polyurethane. The contoured disc gives clearance for the bolt heads, and is able to flex freely to take up any temporary misalignment of the engine and shaft, due to flexing of the boat structure or the engine moving on its rubber vibration isolation mountings. Forward thrust is taken in compression on the disc between the two half couplings and reverse thrust is taken again in compression on the disc between the two fail straps. In the unlikely event of a disc failure the steel straps make the coupling fail safe and ensure drive is maintained in both forward and reverse. <br /> <br /> <b>To calculate power of coupling required:</b> <br /> <u>Horse Power of Engine</u> <sub>x Reduction Ratio x 100 = HP/100RPM</sub> <br /> Engine Speed <br /> <br /> <b>Example:</b> <br />Ford 150 HP at 2500 RPM with Borg Warner Velvet Drive 72C 2:1 Reduction Ratio <br />Engine Horse Power is 150 HP, Max Rated RPM is 2500, Reduction Ratio is 2:1 <br />150/2500 X 2 x 100 = 12hp per 100RPM <br />Coupling required is 910-009 <br /> <br />The R & D Marine Flexible Coupling fits between the transmission output flange and shaft coupling. It is designed to protect a boat's drivetrain. The unit will reduce vibration, compensate for some misalignment, isolate the shaft and absorb shock loads. <br /> <br />The flexible disc is machined from a resilient and durable polyurethane. It allows the unit to flex, absorbing vibrations and temporary misalignment of the shaft and engine due to movement of the engine or flexing in the vessel's structure. <br /> <br />The polyurethane disc is backed up by two metal compression straps, one on either side of the flexible coupling. These metal straps hold the system in constant compression whether the drivetrain is in forward or reverse. This feature extends the life of the system dramatically. <br /> <br />The R & D Marine Flexible Coupling will also absorb shockloads resulting from gear changes, or the propeller striking a submerged object. The polyurethane disk will distort with light shock loads and is designed to be sacrificial in the event of severe shock load, saving on expensive drivetrain repairs. If the disc is destroyed from massive shockload the metal compression straps keep the coupling intact ensuring that the drive system is functional in both forward and reverse. <br /> <br /> <b>Why R&D Marine Flexible Shaft Couplings?</b> <br /> <ul> <li>Polyurethane flange creates a flexible barrier to reduce drivetrain noise and vibration to quiet your drivetrain<br /></li> <li>Absorbs transmission shock load caused by the propeller and high speed gear changes. This helps to reduce and avoid costly transmission damage<br /></li> <li>Fail safe design, both forward and reverse thrust is taken in compression from the steel straps, giving a durable design even in extreme conditions</li> </ul>
<b>Overview:</b> <br /> <br />The HDMI cable is the newest and best digital video connection on the market. HDMI is the only cable that can transfer uncompressed high-definition video and multi channel digital audio in resolutions higher than 1080p. HDMI cables are convenient because they will allow the transfer of digital audio and video in a single cable, permitting a less confusing mess of wires and a cleaner entertainment center. They are backward compatible to all previous versions. <br /> <br /> <b>Main Features:</b> <br /> <ul> <li>1080p Resolution. Audio Return Channel 3D - 3D is the latest rage for both home theater and gaming.</li> <br /> <li>4K - The 4K resolution is 3840 x 2160 pixels @ 24 Hz.</li> <br /> <li>Deep Color - The Deep Color feature provides a minimum of 8-bits per color element (24-bits total), providing for a total of over 16 million color variations. x.v.Color - x.v.Color High Definition Audio - HDMI supports a full range of high definition audio types, including SA-CD, DVD-Audio, DTS-HD Master Audio, and Dolby TrueHD.</li> </ul> <b>Specifications:</b> <br /> <ul> <li><b>Our High Speed HDMI cables</b> with Ethernet have been designed to meet the performance standards set by HDMI 2.0 and have passed stringent Category 2 testing. They are backward compatible to all previous versions.</li> <br /> <li><b>HDMI Ethernet Channel</b> - The HDMI 2.0 specification adds a data channel to the HDMI connection, enabling high-speed, bi-directional communication. Connected devices that include this feature can send and receive data via 100 Mb/sec Ethernet, making them instantly ready for any IP-based application.</li> <br /> <li><b>Audio Return Channel</b> - The new specification adds an audio channel that will reduce the number of cables required to deliver audio """"upstream"""" from a TV to an A/V receiver for processing and playback. In cases where a TV features an internal content source, such as a built-in tuner or DVD player, the Audio Return Channel allows the TV to send audio data upstream to the A/V receiver via the HDMI cable, eliminating the need for an extra cable.</li> <br /> <li><b>3D Support</b> - The version of the specification defines common 3D formats and resolutions for HDMI-enabled devices, enabling 3D gaming and other 3D video applications.</li> <br /> <li><b>4K Resolution Support</b> - The new specification enables HDMI devices to support extremely high HD resolutions, effectively four times the resolution of a 1080p device. Support for 4K allows the HDMI interface to transmit digital content at the same resolution as the state-of-the-art Digital Cinema systems used in many movie theaters.</li> </ul>
