| 摘要 |
The invention provides a change gear sprocket corresponding to chains with relatively short chain pitches. The change gear sprocket (100) is formed by respectively detachably arranging a plurality of change gear bodies (120, 130) with sprockets (121, 131) on a plurality of change gear installation parts (112) formed on the periphery of a sprocket main body (110) in an equal-pitch way. The sprocket main body (110) comprises a polygonal peripheral shape (114)with the same number of sides as the number of the change gear bodies (120, 130). The change gear bodies (120, 130) are configured along the periphery of the sprocket main body (110) in a way to make adjacent change gear bodies (120, 130) contact one another. |
