Abstract
The invention discloses a polygonal chain which comprises outer chain sheets, inner chain sheets, chain rollers and pin shafts. Each outer chain sheet is composed of two chain sheet heads and a connecting portion for being connected with the chain sheet heads. Chamfers are arranged on the chain sheet heads, and waist portions are arranged at the joints of the connecting portions and the corresponding chain sheet heads. The area of the heads of the outer chain sheets of the chain is obviously increased, the smoothness in the speed changing process is improved, and the probability of chain falling is lowered.
Description
Technical field
The present invention relates to field of chain transmission, specifically a kind of polygonal chain.
Background technique
Bicycle is conventional industries, there is the history of more than 100 year, due to the problem of environmental protection and traffic, bicycle become once again countries in the world particularly developed country resident like traffic, fitness tool, the center of gravity of world's bicycle trade just from traditional type of riding instead of walk traffic tool to sports type, mountain, leisure type change, in U.S., Europe, Deng developed country, bicycle is a kind of more general motion, body-building, leisure and recreational product.Annual whole world bicycle demand is huge, and the data statistics display of Japanese CYCLEPRESS, within 2014, whole world bicycle demand size remains on 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 traffic tool of environmental protection; Bicycle is gone on a tour as fitness equipments be used for riding exercise, bicycle by increasing people; The path resource that bicycle takies than automobile is much smaller; Easy to maintenance; Non-exhaust emission, the pollutant such as inorganic oil, freezing mixture; Quiet traveling; Except regular fastening component, do not need the features such as maintenance, thus attract the Consumer changing means of transportation, can delay the speed that Motor Vehicle rises yet.Require from the globalization of energy-saving and environmental protection, low-carbon (LC), 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, be one and translation power is converted into the device of 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, thus bicycle is advanced.Therefore transmission part is extremely important, and the chain in transmission part is core, and can whether chain transmission is smooth and easy directly affects the driving of bicycle and ride and carry out smoothly.
Bicycle chain common on market is usually by outer chain sheet, and inner chain sheet, chain rolls and bearing pin composition, and the shape of outer chain sheet and inner chain sheet is " ∞ " shape, easily can occur falling chain, the phenomenons such as speed change is not smooth if in use concentrated because of inadequate lubrication or driving force.
Summary of the invention
Goal of the invention: the object of the invention is to solve the deficiencies in the prior art, provides a kind of polygonal chain, and the head area of the outer chain sheet of this chain obviously increases, and improves smooth degree during speed change, reduces the probability falling chain.
Technological scheme: in order to realize above object, a kind of polygonal chain of the present invention, it comprises: outer chain sheet, inner chain sheet, chain roll and bearing pin, described outer chain sheet forms by two chain sheet heads with for the joint of connection chain sheet head, chain sheet head is provided with chamfering, and the joint of joint and chain sheet head is provided with waist.
As present invention further optimization, described chain sheet head is polygonal, and the area of outer chain sheet head compared with prior art obviously increases, and engages in advance when chain speed change with fluted disc, 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 play more guiding function to chain, reduce the probability falling chain.
As present invention further optimization, the angle of described chamfering is 35 ° ~ 60 °, and described chamfering is positioned at the outer side of chain sheet head, and chain speed change in transmission process can be made more smooth and easy, reduces the probability falling chain.
As present invention further optimization, described joint is provided with lightening hole, alleviates the weight of chain entirety, improves the transmission efficiency of chain, adds the reliability of chain work.
As present invention further optimization, the curved surface of described waist to be angle the be circular arc of 100 ~ 135 °, the center of circle of the curved surface of waist, in the inner side of outer chain sheet, decreases the noise of chain in transmission process, and makes chain more smooth and easy when speed change.
Beneficial effect: a kind of polygonal chain of the present invention, compared with prior art, has the following advantages:
1, by increasing the head area of outer chain sheet, engaging with fluted disc in advance when speed change, reducing the situation generation that speed change has some setbacks;
2, under nominal operating conditions, because width lengthens, be equivalent to play more guiding function to chain, reduce the probability falling chain;
3, add chamfering by the side outer at chain sheet head, can chain speed change more smooth and easy, reduce and fall the probability of chain;
4, joint is provided with the radian that raises up, and decreases the noise of chain in transmission process, and makes chain more smooth and easy when speed change;
5, by changing the shape of outer chain sheet, making the global design sense of chain stronger, allowing Consumer have more selection when buying chain.
