Description
Technical field
This utility model relates to field of chain transmission, specifically a kind of polygon chain.
Background technology
Bicycle is conventional industries, there is the history of more than 100 year, due to environmental protection and the problem of traffic, bicycle becomes the countries in the world traffic that particularly developed country resident likes, fitness tool once again, the center of gravity of world's bicycle trade just changes to motor type, mountain, leisure type from traditional type of riding instead of walk vehicles, in U.S., Europe, Deng developed country, bicycle is a kind of more universal motion, body-building, leisure and recreational product.Annual whole world bicycle demand is huge, and the data statistics of Japan CYCLEPRESS shows, within 2014, whole world bicycle demand size is maintained at the level of 1.06 hundred million, and bicycle annual volume is about 5,000,000,000 dollars.
Bicycle can be used for riding instead of walk, going on a journey as the vehicles of environmental protection；Bicycle is gone on a tour for exercise of riding, bicycle by increasing people as body-building apparatus；Bicycle is more much smaller than the path resource that automobile takies；Easy to maintenance；Non-exhaust emission, the pollutant such as inorganic oil, coolant；Quiet traveling；In addition to periodically fastening parts, it is not required to the features such as maintenance, thus attracts to change the consumer of walking-replacing tool, also can delay the speed that motor vehicles rises.From the point of view of the globalization of energy-saving and environmental protection, low-carbon (LC) requires, bicycle industry meets present situation and the future directions of China beyond doubt.
When using bicycle, pedal parts is assemblied on the left and right crank of middle axle, being a device that translation power is converted into rotatory force, during cycling, first pedal force passes to pedal parts, then by crank shaft rotating crank, chain wheel, axis, chain flywheel, make rear wheel, so that bicycle advances.Can therefore drive disk assembly be extremely important, and the chain in drive disk assembly is core, the most smooth and easy driving directly affecting bicycle of chain drive and ride and be smoothed out.
Bicycle chain common on market is generally by outer chain sheet, inner chain sheet, and chain rolling is shaped as " ∞ " shape with bearing pin composition, outer chain sheet and inner chain sheet, chain be would tend to occur if in use concentrated because of inadequate lubrication or driving force, the phenomenons such as speed change is the most smooth.
Utility model content

Further preferably described chain sheet head is polygon, and the area of outer chain sheet head the most substantially increases as of the present utility model, engage with fluted disc in advance when chain speed change, reduces the situation generation that speed change has some setbacks.Under nominal operating conditions, because the width of outer chain sheet head lengthens, be equivalent to chain is played more guiding function, reduce the probability falling chain.
Further preferably the angle of described chamfering is 35 °～60 °, and described chamfering is positioned at the side that chain sheet head is outer as of the present utility model, and chain speed change in transmission process can be made more smooth and easy, reduces the probability falling chain.
Further preferably described connecting portion is provided with lightening hole as of the present utility model, alleviates the weight that chain is overall, improves the transmission efficiency of chain, adds the reliability of chain work.
As of the present utility model further preferably, the curved surface of described waist be angle be the circular arc of 100～135 °, the center of circle of the curved surface of waist, in the inner side of outer chain sheet, decreases chain noise in transmission process, and makes chain more smooth and easy when speed change.
Beneficial effect: a kind of polygon chain described in the utility model, compared with prior art, has the advantage that
1, by increasing the head area of outer chain sheet, engage with fluted disc in advance when speed change, reduce the situation generation that speed change has some setbacks；
2, under nominal operating conditions, because width lengthens, be equivalent to chain is played more guiding function, reduce the probability falling chain；
3, chamfering is added by the side outer at chain sheet head, can be more smooth and easy with chain speed change, reduce the probability falling chain；
4, connecting portion is provided with the radian that raises up, and decreases chain noise in transmission process, and makes chain more smooth and easy when speed change；
5, by changing the shape of outer chain sheet, the global design sense making chain is higher, allows consumer have more selection when buying chain.
