Embodiment Construction

[0029] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0030] like figure 1 As shown, the deformed sprocket wheel of this embodiment includes a plurality of wheels 1, and the outer edges of the sides of adjacent wheels 1 are hinged to each other, and the sides of adjacent wheels 1 form an angle or fit each other, and the plurality of wheels The pieces 1 are combined to form a sprocket;

[0031] like image 3 As shown, the structure of a single wheel 1 is as follows: a concave arc structure 15 at the inner edge, a convex arc structure 18 at the outer edge, and the arc structure 15 is concentric with the arc structure 18; Chain teeth are arranged on the shape structure two 18.

[0032] like figure 1 and figure 2 As shown, the wheel 1 includes the first wheel 11 and the second wheel 12, the first wheel 11 and the second wheel 12 are arranged at intervals; the side of a single wheel 11 is at...

Abstract

The invention relates to a deformation chain wheel which comprises multiple wheel pieces and a fixed plate. The outer edges of the sides of the adjacent wheel pieces are hinged; the sides of the adjacent wheel pieces form an angle or fit mutually; the multiple wheel pieces are spliced to form a chain wheel; an installation hole is formed in each wheel piece; a fastening piece is arranged in each installation hole; the chain wheel and the fixed plate are arranged fixedly through the fastening pieces; and the adjacent wheel pieces rotate relative to the hinged point, so that the sides of the adjacent wheel pieces fit mutually or form an angle, the overall chain wheel is changed between a circular shape and an oval shape, and the deformation of the chain wheel is realized. The deformation chain wheel provided by the invention is simple and ingenious in structure, is particularly applicable to an autocar transmission system so as to overcome the defects of an existing single circular-shaped or oval-shaped chain wheel, and is beneficial to greatly improving the riding experience of a user.

Description

technical field [0001] The invention relates to the technical field of sprockets, in particular to a deformed sprocket. Background technique [0002] A sprocket, usually round, is simple to make and most commonly used. [0003] The transmission of force on the pedals in the bicycle field adopts a sprocket structure. During riding a bicycle, the force exerted by the foot on the pedal varies periodically with the change of the position of the crank; since the direction of the foot force is always downward, the same foot force is in different positions of the crank, and the effect of force Instead, foot power works best when the crank is in the horizontal position and worst when it is in the plumb position; hence the elliptical sprocket. [0004] The distance from each tooth on the oval sprocket to the center of the sprocket is different. During the riding process, the length of the force arm will change periodically, and the force applied by the foot to the pedals will also ...
