Description
Technical field
The present invention relates to bicycle chainwheel, more particularly to a kind of modularization makes manufacture production quick, it is possible to decrease manufacturing cost
Bicycle chainwheel group manufacture method.
Background technology
The chain wheel set of general multi-speed bicycle has the sprocket wheel of the multi-disc different size number of teeth, is fitted in jointly on a sleeve,
The sleeve and the heart axle for being socketed in flower hub after one, the trailing wheel connection of the rear colored hub and bicycle, and treadled cycle pedal can band
Dynamic large fluted disc group rotation, hangs by means of a chain between the large fluted disc group and the chain wheel set and connects, can coordinate different road conditions
Change chain by means of a speed changer of bicycle and hang a wherein large fluted disc for large fluted disc group and a wherein sprocket wheel for chain wheel set, and band
Dynamic bicycle advances.
Because the series of bicycle variable-ratio is more, the sprocket wheel quantity assembled in chain wheel set is relatively most, such as Fig. 1 and
Fig. 2 show TaiWan, China new patent M451318 bicycle chainwheel groups, and it includes a pedestal 60, plural long fixture
70 with short fixture 74, the big sprocket wheel 80 of a maximum outside diameter, one first sprocket wheel 90, one second sprocket wheel 91, one the 3rd sprocket wheel 92 and
One the 4th sprocket wheel 93, the pedestal 60 has a cylindric body 61, and the outer ring portion of body 61 is furnished with six branch gripping arms 62, supports
Arm 62 has relative a first surface 63 and a second surface 64, and second surface 64 is provided with one first stepped rank portion
641 and a second-order portion 642, the thickness in the first rank portion 641 is more than the thickness in second-order portion 642, the first rank portion 641 and second-order
Portion 642 is respectively provided with a through hole 65, the first surface 63 of branch gripping arm 62 is provided with a big sprocket wheel 80, and to should the first rank portion 641
Through hole 65 is provided with mounting hole 81, and the first sprocket wheel 90, the second sprocket wheel 91, the 3rd sprocket wheel 92 and the are sequentially installed in the direction of second surface 64
Four sprocket wheels 93, the first sprocket wheel 90, the second sprocket wheel 91, the 3rd sprocket wheel 92 and the 4th sprocket wheel 93 correspond to the long annular point of fixture 70 respectively
It is furnished with plural mounting hole 901,911,921,931.Long fixture 70 has a large-diameter portion 71, a long column 72 and a short column 73, makes
First sprocket wheel 90 is riveted by means of its mounting hole 901 with long fixture 70, long fixture 70 and the mounting hole 911 for passing through the second sprocket wheel 91
And first rank portion 641 through hole 65, then penetrate the mounting hole 81 of big sprocket wheel 80, big sprocket wheel 80 be riveted on first surface 63.
Short fixture 74 has a large-diameter portion 75, a long column 76 and a short column 77, and the 3rd sprocket wheel 92 is borrowed with the 4th sprocket wheel 93
The short column 77 of short fixture 74 passes through the mounting hole 921 and rivet clasp of the 3rd sprocket wheel 92, and the long column 76 of short fixture 74 passes through the 4th
The mounting hole 931 of sprocket wheel 93 and the through hole 65 of branch gripping arm 62 and riveted.So make the first sprocket wheel 90, the second sprocket wheel 91, the 3rd chain
Wheel the 92, the 4th sprocket wheel 93 and big sprocket wheel 80 by plural long and short fixture 70,74 wear and riveted is consolidated with pedestal 60 jointly
Integrally.
In assembling, it is necessary to one end of long fixture 70 is passed through the mounting hole 901 of the first sprocket wheel 90 by manpower, and
The other end and through the second sprocket wheel 91 the rank portion 641 of mounting hole 911 and first through hole 65 and be riveted on first surface 63.It is short solid
Its short column 77 of part 74 is determined through the mounting hole 921 and rivet clasp of the 3rd sprocket wheel 92, and short fixture 74 passes through the 4th with its long column 76 again
The mounting hole 931 of sprocket wheel 93 and the through hole 65 of branch gripping arm 62 and riveted, it can be seen that, assembling process is very time-consuming bothersome, each group
The precision that part cooperates is difficult to control to, and does not meet economic needs.
