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
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 ...
The full chisel chain has square-cornered teeth, splitting wood fibers easily in the cut for fast, efficient cutting in clean softwood. Chisel chains have a high kick-back risk due to missing safety chain elements and are more sensitive against dirt. These chains are available for semi-pro (also called pro-sumer) and professional saws.
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.
Sprockets typically do not have a flange. Some sprockets used with timing belts have flanges to keep the timing belt centered. Sprockets and chains are also used for power transmission from one shaft to another where slippage is not admissible, sprocket chains being used instead of belts or ropes and sprocket-wheels instead of pulleys. They can ...
Woody Harrelson and Ted Danson’s decades-long friendship reached a new level after Danson helped patch up his former Cheers costar following a motorcycle accident. Danson, 76, and Harrelson, 62 ...
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 ...
