The X-ring chain is a specialized type of sealed roller chain used to transfer mechanical power. Like the standard O-ring chains it is also used in high-performance motorcycles. It uses X-ring seal to keep lubricant (usually grease ) in place.
The custom of lubing by immersing the chain in a tin of hot grease ceased in the early 1970s, once most chains had rubber "O'-rings. The original Suzuki RE5 of 1975 came with a rear chain oiler, but the 1976 model had a sealed chain, and its oiler was deleted as "unnecessary". A Honda step-thru with an enclosed chain
A safety wire is used to ensure proper security for a fastener. The wire needed is long enough to reach from a fixed location to a hole in the removable fastener, such as a pin — a clevis fastener, sometimes a linchpin or hitch-pin through a clevis yoke for instance — and the wire pulled back upon itself, parallel to its other end, then twisted, a single end inserted through a fastener ...
O-ring chains are most notably used in motorcycles, one of the most demanding applications for a metal chain. High rpm and heavy loads require bulky chains, but such engineering increases the effect of friction compared to lighter chains. So lubrication plays a vital role here, but the high rpm also makes it very difficult to keep lubrication ...
Roller chain and sprocket The sketch of roller chain, Leonardo da Vinci, Codex Atlanticus. Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles.
Although the device did not transmit power continuously since the chains "did not transmit power from shaft to shaft, and hence they were not in the direct line of ancestry of the chain-drive proper", [4] the Greek design marks the beginning of the history of the chain drive since "no earlier instance of such a cam is known, and none as complex ...
They offer chains with hollow pins and with cut-outs in the links and made of stainless steel, with a titanium nitride coating, or painted in a variety of colors. [2] In 2012, KMC launched a chain model specifically for electric bicycles. [13] In 2010, KMC won the iF Product Design Gold Award for its BMX ‘Kool Knight Chain’. [14]
[citation needed] The next-more complex method than the simple nut is a split nut, whose halves can be adjusted, and locked with screws, so that the two sides ride, respectively, against leftward thread and the other side rides rightward faces. Notice the analogy here with the radio dial example using split gears, where the split halves are ...
