Description
Technical field
The invention belongs to bike flywheel gear technical fields, and in particular to a kind of non-return ring type bicycle freewheel.
Background technique
Flywheel is one of components important on bicycle, currently on the market except cassette flywheel (itself is not able to rotate, borrows
Column foot is just able to rotate) outside, all rotated substantially by steel ball, between steel ball and steel ball and steel ball and product relative slot compared with
Greatly, it is easy into rainwater, into dust, sand causes flywheel stuck, in addition, very heavy (non-return keys) and spring are used when driving flywheel,
It easily gets rusty, causes flywheel fails, and steel ball itself gets rusty easily, consequent effects rotation and increase noise, or even rust are dead.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of non-return ring type bicycle freewheel
Problem.
To achieve the above object, the invention provides the following technical scheme: a kind of non-return ring type bicycle freewheel, including non-return
Ring, inner core and shell, the inside at the shell both ends is embedded with self-lubricating bearing I and self-lubricating bearing II respectively, described from profit
The one end fits for the inner core being arranged in plain besring I and shell are connect, and the middle section outer rim of the inner core is provided with keyway, the non-return
Ring is fixed on keyway, and the outer rim of the non-return ring is provided with the elastic slice matched with shell internal segment tooth, the cover board and inner core
Between be provided with adjusting washer.
Preferably, the inner hole wall of the non-return ring is equipped with the keyway matched with inner core outer rim keyway.
Preferably, the section tooth is distributed on the inner wall of shell and is oppositely arranged with non-return ring.
Preferably, clearance fit has cover board in the inner circumferential of the self-lubricating bearing II, and the cover board passes through screw thread and inner core
Threaded one end connection.
Technical effect and advantage of the invention:
The steel ball that the present invention is used by self-lubricating bearing instead of original, self-lubricating bearing I, self-lubricating bearing II are with inner core and outside
It is fitted close between shell, rainwater, dust can be effectively prevent, sand enters flywheel, when extending the antirust and lubrication inside flywheel
Between, extend flywheel service life, by the way that non-return ring is arranged, avoiding flywheel because very heavy and spring gets rusty, the bring that falls off is bad
Afterwards, stability is more preferable, comfort of riding.
Detailed description of the invention
Fig. 1 is configuration schematic diagram of the invention；
Fig. 2 is side structure schematic diagram of the invention；
Fig. 3 is A-A the schematic diagram of the section structure in Fig. 2 of the invention.
In figure: 1 self-lubricating bearing I, 2 non-return rings, 3 cover boards, 4 inner cores, 5 adjusting washers, 6 shells, 7 self-lubricating bearings II.
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the scope of protection of the invention.
As shown in Figure 1-3, a kind of non-return ring type bicycle freewheel, including non-return ring 2, inner core 4 and shell 6, the shell 6
The inside at both ends is embedded with self-lubricating bearing I 1 and self-lubricating bearing II 7 respectively, is arranged in the self-lubricating bearing I 1 and shell 6
Inner core 4 one end fits connection, the middle section outer rim of the inner core 4 is provided with keyway, and the non-return ring 2 is fixed on keyway,
The outer rim of the non-return ring 2 is provided with the elastic slice matched with 6 internal segment tooth of shell, is provided with tune between the cover board 3 and inner core 4
Whole washer 5.
Self-lubricating bearing I 1 is installed with self-lubricating bearing II 7 using following any mounting means:
1. the outer ring of bearing and 6 inner edge of shell relatively rotate；
2. one end of the inner ring of bearing and inner core 4 relatively rotates.
The inner hole wall of the non-return ring 2 is equipped with the keyway matched with 4 outer rim keyway of inner core.Non-return ring 2 and inner core 4 it
Between be fixed by the way that the mutual interference of keyway is chimeric.Non-return ring 2 is made of match steel, and non-return ring 2 is whole to be the integrated design, and is had
The advantage for having structural strength high, wear-resisting can satisfy design and use.
The section tooth is distributed on the inner wall of shell 6 and is oppositely arranged with non-return ring 2.Utilize section tooth and elastic slice phase interworking
It closes, inner core 4 can be driven.
Clearance fit has cover board 3 in the inner circumferential of the self-lubricating bearing II 7, and the cover board 3 passes through screw thread and the one of inner core 4
End is threadedly coupled.Cover board 3 covers inner core 4 and one end of shell 6, protects internal inner core 4 and self-lubricating bearing II 7.
Specifically, the section tooth of 6 inner edge of shell can withstand non-return ring 2 in use, shell 6 is rotated by chain pull when riding
The elastic slice of outer rim, elastic slice drives non-return ring 2 to rotate, and since non-return ring is connect with inner core by spline, driving inner core 4 is driven
Vehicle wheel rotation.When idle running, shell 6 does not turn or inverts, elastic slice sliding opposite with the section tooth on shell 6.
The present invention by self-lubricating bearing instead of the steel ball that uses of original, self-lubricating bearing I 1, self-lubricating bearing II 7 with it is interior
It is fitted close between core 4 and shell 6, rainwater, dust can be effectively prevent, sand enters flywheel, extends the antirust inside flywheel
And lubrication time, extend flywheel service life, by the way that non-return ring 2 is arranged, flywheel is avoided to fall off band because very heavy and spring gets rusty
Come it is bad after, stability is more preferable, comfort of riding.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features,
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
