鎖牙跟卡式都是飛輪,卡式只有把飛輪拆開,單一片體才叫齒片,不要誤導

嗯嗯^^
其實我也在查"花鼓"音譯一說的由來，只可惜一直查不到較具公信力的資料....不然hub唸起來的確蠻有"花"鼓的感覺...
另外有一說是之所以叫"花"轂，只取其"形"而來 (輪組中心看起來像花)，不過一樣查不到具公信力出處就是了^^
沒錯~~bearing (嚴格來說是培林這個譯名) 這個詞倒是真的困惑了不少人^^

y拍賣家說的沒錯啊^^
簡單說明一下好了...
齒片 >> cog；sproket (一般來說sproket專用於鍊條帶動之齒片，cog原意為棘齒、亦泛指齒片)
齒片組 (一般通稱為飛輪) >> cogset；涵蓋cassette卡式飛輪、及freewheel鎖牙飛輪
另外補充一些其它的：
卡式飛輪座 >> freehub (與花轂一體，用來裝置卡式飛輪的"座", 內含棘輪)
鎖牙式飛輪 >> freewheel (內建棘輪的齒片組/飛輪)
卡式飛輪 >> cassette (不含棘輪，一般大廠如sram等皆稱其卡式飛輪為cassette)
齒片組 >> cogset (cassette 和 freewheel的通稱)
值得注意的是，freewheel雖因與cassette區別的必要性而稱為鎖牙式飛輪，但就定義上來說所有的飛輪皆可稱之為freewheel (詳見wikipedia說明如下)
Wikipedia原文如下：
cogset：
On a bicycle, the cogset is the set of rear sprockets that attaches to the hub on the rear wheel. A cogset works with a rear derailleur to give multiple gear ratios to the rider. Cogsets come in two varieties, cassettes or freewheels, of which cassettes are a newer development. Although cassettes and freewheels perform the same function and look almost the same when installed, they have important mechanical differences and are not interchangeable. Because many bicycle users do not understand the differences, the terms are sometimes incorrectly used interchangeably.
sproket：
A sprocket is a profiled wheel with teeth that meshes with a chain, track or other perforated or indented material. It is distinguished from a gear in that sprockets are never meshed together directly, and from a pulley by not usually having a flange at each side.
Sprockets are used in bicycles, motorcycles, cars, tanks, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape etc.
cog related:
A gear is a component within a transmission device that transmits rotational force to another gear or device. A gear is different from a pulley in that a gear is a round wheel which has linkages ("teeth" or "cogs") that mesh with other gear teeth, allowing force to be fully transferred without slippage. Depending on their construction and arrangement, geared devices can transmit forces at different speeds, torques, or in a different direction, from the power source.
freehub:
A freehub is an axle assembly, used notably for the rear axle of bicycles. Freehubs incorporate a ratcheting mechanism. Separately, a set of sprockets (called a "cassette") are mounted onto a splined shaft on the freehub. In contrast, a freewheel contains both the chain gear cogs and a ratcheting mechanism in a single unit. In many high-end and midrange bicycles, freehubs have replaced the traditional, heavier and more exposed freewheel systems.
freewheel:
In mechanical or automotive engineering, a freewheel or overrunning clutch is a device in a transmission that disengages the driveshaft from the driven shaft when the driven shaft rotates faster than the driveshaft. An overdrive is sometimes mistakenly called a freewheel, but is otherwise unrelated.
