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 the structural schematic diagram of the integral type flywheel first half of the utility model；
Fig. 2 is the structure another kind embodiment of the integral type flywheel first half of the utility model.
Specific implementation mode
As shown in Figure 1, a kind of integral type flywheel, includes cone pulley 1, the wheel being overlapped to form by the gear ring that multilayer diameter is sequentially increased
Hub 2 and antitorque gear ring 3.Diameter minimum is the first gear ring 11 in multilayer gear ring, and it is second that diameter is maximum in multilayer gear ring
Gear ring 12.Antitorque gear ring 3 is removably fixed with the second gear ring 12, and fixed mode can be riveting, be threadedly coupled or weld
The one kind connect.Wheel hub 2 is tubular, and one end of wheel hub 2 and the smaller diameter end of cone pulley 1 are detachably connected, such as elastic conjunction, riveting
It connects, be threadedly coupled or weld；The other end of wheel hub 2 and 3 integrally connected of antitorque gear ring.One end and resist that cone pulley 1 is relatively large in diameter
It turns round the overlap joint of gear ring 3 and forms the first overlapped joints 8, it is more excellent in a manner of by the second gear ring 12 and antitorque gear ring 3, overlapped so that structure phase
It is easy to process to simple；The smaller one end of 1 diameter of cone pulley forms the second overlapped joints 9 with the overlap joint of wheel hub 2, with the first gear ring 11
Overlapped that mode is more excellent with wheel hub 2 so that structure is relatively easy, easy to process.Thus, it is only necessary to pass through the first overlapped joints 8,
Two overlapped joints 9 may make cone pulley 1, wheel hub 2 and antitorque gear ring 3 to form a stable triangle knot on axial section
Structure.Since wheel hub 2 and antitorque gear ring 3 are integrated so that the stress of flywheel is more split type evenly, avoids 2 He of wheel hub
The binding site that antitorque gear ring 3 disconnects occurs loosening sliding；Meanwhile being wholely set wheel hub 2 and antitorque gear ring 3, it can avoid existing
Have in flywheel, in cone pulley 1 and antitorque gear ring 3, wheel hub axially can only bear axial compressive force and cannot hold for the setting that wheel hub 2 detaches
By the defect of pulling force so that flywheel has better adaptability for bicycle stressing conditions complicated in high-speed motion, greatly
The intensity and antitorque stress-bearing capability of big raising flywheel entirety so that flywheel stabilization is good, intensity is high.
Preferable embodiment, as shown in Fig. 2, antitorque gear ring 3 includes the first disc 34, third gear ring 35 and the 4th tooth
Circle 39, third gear ring 35 and the 4th gear ring 39 with 34 integrally connected of the first disc.Specific connection type can be by third tooth
Circle 35 is arranged in the outer of the first disc 34, from the first disc 34 it is axially outwardly extending go out first muscle 37, and with first
Muscle 37 extends up to the second disc 38, and the second disc 38 is parallel with the first disc 34, and the 4th gear ring 39 is arranged in the second disc 38
Outer.So that the 4th gear ring 39 is parallel with both third gear rings 35, ensure that the speed changing function of flywheel is normally realized.By anti-
It turns round gear ring 3 and concentrates third gear ring 35 and the 4th gear ring 39 simultaneously so that the gear ring number of plies of flywheel additionally increases.Using this structure
Benefit be also apparent, the speed change number of current kinetic bicycle freewheel is even higher to 12 speed, and the flywheel of integral type is usual
It is that raw metal is forged into idiosome by equipment, then carries out tooth processing again, and the flywheel of integral type often increases by one layer of gear ring, forging
The axial dimension of pressure is longer, also higher to the forging and stamping Capability Requirement of equipment, as long as such as the flywheels of 12 speed ability is forged and pressed to equipment
400t is sought, but when needing more transmission ranges, such as becoming 13 speed by 12 speed, the forging and stamping of equipment are required to arrive with regard to increasing sharply
1000t even more than, often increase by one speed, need additionally to increase a gear ring, to equipment requirement in geometry multiple rise, also,
The equipment of high forging and stamping ability has very huge pressure in service life, plant maintenance and acquisition cost, thus by
Cone pulley 1 is combined with antitorque gear ring 3, and concentrates third gear ring 35 and the 4th gear ring 39 additionally to increase the gear ring number of plies in antitorque gear ring 3
Alleviate such case significantly, versatility is good, while so that equipment cost is low, properties of product are stable, good manufacturability.
Preferable embodiment, as depicted in figs. 1 and 2, the second gear ring 12 include third disc 122 and with third disc
The outer portion in third disc 122 is arranged in second muscle 123 of 122 connections, the work tooth 121 of the second gear ring 12.Second muscle
123 for connecting last layer gear ring and the second gear ring 12 in cone pulley 1, and it is at different levels to add a circumferentially uniformly distributed cylinder muscle realization by disc
The connection relation of gear ring.When antitorque gear ring 3 is connect with cone pulley 1, the first disc 34 is passed through into riveting, screw thread with third disc 122
The modes such as connection, welding, elastic conjunction are directly or indirectly fixed as one.For example, in the first disc 34 and third disc
Through-hole (not marked in figure) is opened up on 122, and is connected as one the first disc 34 with third disc 122 by fixed part 7.
Certainly, it is different from the embodiment of the preceding paragraph, can also be that second muscle 123 and the first disc 34 is directly fixed
Connection, as long as can be so that antitorque gear ring 3 connect reliably secure, simple in structure and technique with cone pulley 1 well.
Preferable embodiment is conducive to mitigate the matter of flywheel as shown in Fig. 2, being provided with lightening hole 36 on the first disc 34
Amount.
Preferable embodiment, as depicted in figs. 1 and 2, wheel hub 2 can be connected by the way that spline 22 is arranged with axis synthesis.Together
When, weight loss groove 21 can be added on wheel hub 2 reduces flywheel total quality without influencing rigidity.
Light-weighted aluminium alloy gear ring can be used in preferable embodiment, antitorque gear ring 3 and wheel hub 2, antitorque in guarantee
While the intensity and toughness of gear ring 3, ensure that the quality of flywheel entirety is unlikely to too high.
Preferable embodiment, as shown in Fig. 2, the first gear ring 11 is removably connected with the 5th gear ring 10, the side of connection
Formula can be one kind of welding, threaded connection or riveting.The 5th gear ring 10 is directly added by the smaller diameter end in cone pulley 1, is risen
To effect similar with the 4th gear ring 39, the idiosome of flywheel is reduced in the size longitudinally forged and pressed so that good manufacturability.
Preferable embodiment, as shown in Fig. 2, the 5th gear ring 10, the first gear ring 11, the second gear ring 12, third gear ring 35
And 39 diameter of the 4th gear ring is sequentially increased so that the flywheel after riveting is a conic tower type, ensures that the function of flywheel multi-speed is real
It is existing.
Above example is only to illustrate the technical solution of the utility model and is not intended to limit it, all without departing from this
Any modification of utility model spirit and scope or equivalent replacement should all cover the range in technical solutions of the utility model
It is interior.
