Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, wherein：
Fig. 1 is support portion and gear ring relationship partial schematic diagram；
Fig. 2 is wherein one section of schematic three dimensional views of flywheel.
Specific embodiment
Component in present embodiment, such as first order support portion 1 and second level support portion 1a, the first disc 2 and the second spoke
Plate 2a, first muscle 3 and second muscle 3a and the first gear ring 6 and third gear ring 6a etc., form, structure and size are identical
Or it is similar, it should be representative when repeating component and accordingly expanding.
As shown in Figure 1, a kind of high rigidity integral type flywheel, including it is multiple it is of different sizes, for receiving chain and will be by
The peripheral force that the chain transmits reaches the gear ring of bicycle rear wheel hub and the support portion of the annular for fixed gear ring, the chain
Item can shift to another gear ring by gear from a gear ring；Support portion includes the first order being made of disc and cylinder muscle
Support portion 1, second level support portion 1a ... and so on；First order support portion 1 includes the first disc 2 and is distributed in the first disc
Several first muscle 3 on 2, second level support portion 1a includes the second disc 2a and several are distributed on the second disc 2a
Second muscle 3a, and so on；Between adjacent support portion, cylinder muscle wherein one end of the first disc 2 and next stage support portion
Overlap joint forms the first overlapped points 4, and the inside of one end of first muscle 3 and the first disc 2 overlaps, the other end of first muscle 3 with
Second disc 2a lateral overlaps are fixed to form the second overlapped points 4a；First gear ring 6 is fixed in the first overlapped points 4, third gear ring
6a is fixed on the second overlapped points 4a；Disc is excessively thin according to the annular sheet metal that the characteristic difference of material can be 0.5~2.5mm thickness
It influences intensity and subsequent manufacturing procedure and such as reduces repeated hole or lightening grooves, blocked up one cause material cost to waste, and processes
Tool wear is relatively fast, and causes the volume increase of flywheel；Inside of first disc 2 far from the first gear ring 6 has in company
Continue the ring muscle 5 of annular；The peripheral force that chain transmits forms twisting force to the first overlapped points 4 by the first gear ring 6, and then transmits
Onto the first disc 2, since the first disc 2 is one piece of whole plate, the torque of transmission is uniformly disperseed, therefore in the circumferential firm
Degree and antitorque deformability will be higher by much compared with the form of disconnection so that antitorque strong possessed by flywheel under equal quality
Degree, rigidity and service life service life greatly improve.
Meanwhile at least one layer of second gear ring 7 is radially provided on first muscle 3, it is contemplated that the form of flywheel entirety, ruler
Very little and weight factor, increased second gear ring, 7 quantity is preferred with one to four layers on first muscle 3, and quantity is too many, can influence
Support strength and the craftsmanship of processing；The fixed point of second gear ring 7 and first muscle 3 is third overlapped points 10；It retouches for convenience
It states and understands, although the second gear ring 7, there is no corresponding to support portion, this section and following it is still assumed that a supporting member should
Supporting member is first order support portion 1, second level support portion 1a or similar structure, which originally set in not use
Support and fixed structure necessary to each layer of gear ring during meter scheme；It is set by present design by what at least two layers of gear ring merged
It counts onto a support portion so that one layer of supporting member is corresponded to from one layer of gear ring of script structure and becomes present two or more layers
Gear ring shares a support portion, eliminates the supporting member for corresponding to the second gear ring 7 originally, plays the role of simplified structure,
Although first muscle 3 is considered to combine multilayer gear ring, the distance between gear ring is constant, it is therefore desirable to overstriking and add
It is total to omit one layer of supporting member rear flywheel for height, but correspond to relative to one layer of gear ring of script structure the form of a supporting member
Quality is to reduce, and because the rigidity in first 3 overstriking of muscle its circumferential direction and anti-twisting property are risings；Simultaneously because first
Cylinder muscle 3 highly improves so that the distance between adjacent first disc, 2 and second disc 2a is greatly increased, in processing and fabricating gear ring
Especially when the number of teeth of adjacent gear ring differs less processing, the space that process tool can transfer to other use increases, and can as needed select more
For suitable cutter and more suitable feed withdrawing distance, and finally so that region metalworking work between first muscle 3
Skill significantly optimizes, and quality is more preferably, and the region between second muscle 3a is similarly.
Preferably embodiment, as depicted in figs. 1 and 2, the outer diameter of support portion are identical with the internal diameter of corresponding gear ring, thus lead to
It crosses all support portion disc and forms multistage stair-stepping cone-shaped component 9 with cylinder muscle sequence overlap joint, corresponding gear ring is fixed on taper structure
A portion of flywheel or flywheel is formed on part 9, the connection mode of gear ring and cone-shaped component 9 can be integrally connected,
It can be machined to two individual modules and the two is connected as by a non-removable unit by subsequent technique again, recommend
It is to use above-mentioned disc, cylinder muscle and gear ring being process by one piece of integral material, so that between different components
Connection more fastens, and form twisting force by the first gear ring 6 by the peripheral force that chain transmits (does not mark to overlapped points in figure
Number), and then it is transmitted on the first disc 2, the first disc 2 is again by moment loading to first muscle 3, and first muscle 3 is by torque
Be transferred to the first overlapped points 4 be transitioned into again on the disc of next stage support portion and so on and be finally applied to the branch of minimum diameter
On support part (not marked in figure), the support portion of minimum diameter is connect with the shaft wheel hub on bicycle so that even if support
Portion is not provided with wheel hub, it is also possible that flywheel realizes the transmission of whole torsion and opposite with wheel hub.
Preferably embodiment, as shown in Fig. 2, passing through first muscle 3 between adjacent the first disc 2 and the second disc 2a
Form support, first adjacent muscle 3 of any two, the first disc 2 positioned at upside and the second disc 2a positioned at downside
