Abstract

The utility model discloses a self-lubricating bearing flywheel, including inner core and shell, the both sides of shell inner edge are provided with self-lubricating bearing I and self-lubricating bearing II respectively, the one end interference fit of the inner core that self-lubricating bearing I and shell endotheca were established is connected, be equipped with very heavy groove on the middle section outer wall of inner core, very heavy inslot activity is equipped with very heavy, still install in the very heavy inslot and be used for blocking very heavy spring. The utility model discloses a self-lubricating bearing I and self-lubricating bearing II design very little with the cooperation size of flywheel part, prevent that rainwater and dust grit from getting into the flywheel, sealed effectual can prevent simultaneously that the steel ball from rustting the bad consequence of bringing, and good leakproofness can multiplicable flywheel inside rust-resistant and lubricated time again, noise abatement, increase of service life.

Description

Self-lubricating bearing flywheel

Technical Field

The utility model belongs to the technical field of the flywheel device, concretely relates to self-lubricating bearing flywheel.

Background

The flywheel is one of important spare parts on the bicycle, except that cassette flywheel (itself can not rotate, just can rotate with the help of the column foot) on the market at present, all rely on the steel ball to rotate basically, relative gap is great between steel ball and product, advances rainwater easily, advances dust, grit, causes the flywheel card to die, and the steel ball itself rusts easily, and later stage influence rotates and noise abatement, rusts even and dies.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a self-lubricating bearing flywheel to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a self-lubricating bearing flywheel, includes inner core and shell, the both sides of shell inner edge are provided with self-lubricating bearing I and self-lubricating bearing II respectively, the one end interference fit of the inner core that self-lubricating bearing I and shell endotheca were established is connected, be equipped with very heavy groove on the middle section outer wall of inner core, very heavy inslot activity is equipped with very heavy, still install in the very heavy inslot and be used for blocking very heavy jack spring, be equipped with the festival tooth on the inner wall of shell for a week at very heavy place, interior week clearance fit of self-lubricating bearing II has the apron, the apron passes through the one end threaded connection of screw thread and inner core, still be equipped with adjusting washer between apron and the inner.

The utility model discloses a technological effect and advantage:

the matching size through self-lubricating bearing I and self-lubricating bearing II and flywheel part designs very little, prevents that rainwater and dust grit from getting into the flywheel, and is sealed effectual, can prevent simultaneously that the steel ball from rustting the bad consequence that brings, and good leakproofness can multiplicable flywheel inside rust-resistant and lubricated time again, noise abatement, increase of service life.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the cross-sectional structure a-a in fig. 1 according to the present invention.

In the figure: 1 self-lubricating bearing I, 2 jacks, 3 jack springs, 4 cover plates, 5 inner cores, 6 adjusting washers, 7 outer shells and 8 self-lubricating bearings II.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-2, a self-lubricating bearing flywheel, includes inner core 5 and shell 7, the both sides of shell 7 inner edge are provided with self-lubricating bearing I1 and self-lubricating bearing II 8 respectively, the one end interference fit of inner core 5 that self-lubricating bearing I1 and shell 7 endotheca were established is connected, be equipped with the jack groove on the middle section outer wall of inner core 5, the activity of jack inslot is equipped with very heavy 2, still install the spring 3 that is used for blocking very heavy 2 in the jack groove.

And the inner wall of the shell 7 is provided with pitch teeth in a circle corresponding to the position of the jack 2.

And a cover plate 4 is in clearance fit on the inner periphery of the self-lubricating bearing II 8, and the cover plate 4 is in threaded connection with one end of the inner core 5 through threads.

An adjusting gasket 6 is arranged between the cover plate 4 and the inner core 5.

When the shell 7 is pulled by the chain and the vehicle needs to move forward, the sectional teeth on the inner edge of the shell 7 can prop against the jack 2, the inner core 5 is driven by the jack 2, and the inner core 5 drives the wheel to rotate. At the moment, the self-lubricating bearing I1 can bear the pressure transmitted from the outer shell 7 to the inner core 5, and when the flywheel idles, the self-lubricating bearings II 8 at two ends of the outer shell 7 respectively rotate relative to the large end of the inner core 5 and the cover plate 4.

Through the cooperation size design of self-lubricating bearing I1 and self-lubricating bearing II 8 and flywheel part very little, prevent that rainwater and dust grit from getting into the flywheel in, sealed effectual can prevent the steel ball simultaneously and rust the bad consequence that brings, good leakproofness can multiplicable flywheel inside rust-resistant and lubricated time again, noise abatement, increase of service life.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
