Description
Technical field
The utility model belongs to machine driven system technical field, more particularly to a kind of flywheel.
Background technology
The flywheel used at present in the plant equipment such as bicycle, electric car, the steel ball in it is axial end circular arc
Supporting, the closely coupled roller of ball is pasted by the steel ball ball in both ends of the surface arc raceway, and frictional force is big, and service life is short.In addition,
When flywheel works, flywheel casing, which is rotated, drives steel ball along the steel ball rolling path rolling on the inside of inner core outside and flywheel casing；Work as flywheel
When shell is reversely rotated, steel ball lacks braking and is not turned in time under inertia and produce flywheel and rock space, easily make
Into the damage of flywheel.
The content of the invention
Not enough more than present in prior art to solve, the utility model aims to provide a kind of flywheel, noise during rotation
It is small, flywheel casing and inner core automatic clutch are made during revolution, space is rocked when reducing reversion.
To achieve the above object, the technical scheme that the utility model is used is as follows：A kind of flywheel, including flywheel casing,
In core and the positive frame of guarantor that is placed between flywheel casing and inner core, the positive frame upper surface of guarantor is circumferentially arranged with the card for putting steel ball
It is provided with the inside of groove, flywheel casing and on the outside of inner core the steel ball raceway for rolling steel ball；It is described protect positive frame lower surface circumferentially arranged with
The groove of brake block and spring is put, brake block is in contact with the outside of inner core and on the inside of flywheel casing, and spring connects with brake block
Touch and brake block can be promoted；It is close with formation on the outside of inner core on the inside of flywheel casing provided with making below the top of the steel ball and brake block
Close the enclosing cover in space.
Improved as of the present utility model, described protect is provided with card between positive frame lower surface and enclosing cover, protect positive frame lower surface
Circumferentially arranged with raised corresponding groove on card.
As another improvement of the present utility model, the brake block on the outside of inner core and on the inside of flywheel casing for face with connecing
Touch.
As a result of above-mentioned technical scheme, compared with prior art, acquired beneficial effect is the utility model：
The steel ball raceway of the utility model flywheel is located on the outside of inner core with the relative position on the inside of flywheel casing, making steel ball
Between be connected by protecting positive frame, original steel ball ball is pasted into ball, and closely supporting supports to protect positive frame, steel ball by protect positive frame it is uniform every
Rolling is opened, such bearing structure frictional force is significantly reduced, effectively reduce noise, improve the kinematic accuracy of flywheel, extension flies
The service life of wheel；
The utility model flywheel protects positive frame lower surface and is provided with the spring being in contact with brake block, when flywheel casing reversely turns
When dynamic, brake block is promoted under the action of the spring, makes brake block and flywheel casing extrusion friction, realize flywheel casing with protecting positive frame
Automatic clutch, it is to avoid steel ball lacks braking and do not turn in time under inertia and produce flywheel and rock space, make transmission
Reliably, clutch is sensitive, and flywheel is durable；
The utility model flywheel is provided with shell, card, makes on the inside of flywheel casing with forming confined space on the outside of inner core, prevents
Dirt, anti-gray；
The utility model is simple in construction, easy to assembly.
The utility model is applied in the plant equipment such as bicycle, electric car, motorcycle, for machine driving.
Brief description of the drawings
Below in conjunction with the accompanying drawings and specific embodiment is further described in detail to the utility model.
Fig. 1 is the configuration schematic diagram of the utility model embodiment；
Fig. 2 is the positive lower surface structure sectional view of frame 3 of guarantor of the utility model embodiment；
In figure：1st, flywheel casing；2nd, inner core；3rd, positive frame is protected；4th, steel ball；5th, brake block；6th, spring；7th, enclosing cover；8th, card.
Embodiment
Embodiment
A kind of flywheel, as shown in Figure 1, 2, including flywheel casing 1, inner core 2 and is placed between flywheel casing 1 and inner core 2
Protect positive frame 3.
Protect the positive upper surface of frame 3 and be circumferentially uniformly provided with neck, neck and be installed with steel ball 4, the inner side of flywheel casing 1 and inner core
2 outsides are opposite provided with the raceway of steel ball 4 for rolling steel ball 4, when the flywheel is worked, and steel ball 4 is along the rolling path rolling of steel ball 4.
Protect the positive lower surface of frame 3 and be circumferentially uniformly provided with the groove for being placed with brake block 5 and spring 6, put the groove edge of brake block 5
Rotation direction is tilted, and is through to outside from the inner side for protecting positive frame 3, is placed on brake block 5 and the inner outside of core 2 and flywheel in groove
The inner side of shell 1 is in contact.Put the groove of spring 6 and be connected with putting the groove of brake block 5, and perpendicular to the groove for putting spring 6, bullet
Spring 6 is placed on groove interior energy and is in contact with brake block 5, and can promote brake block 5.Brake block 5 is cuboid of the two ends with radian
Shape, makes brake block 5 be contacted with the inner outside of core 2 and the inner side of flywheel casing 1 for face.
Protect the positive lower surface of frame 3 and be circumferentially uniformly provided with groove, protect and card 8 is provided between the positive lower surface of frame 3 and enclosing cover 7, card
Piece 8 is provided with the projection being adapted with groove, card 8 is fixed on the positive lower surface of frame 3 of guarantor.
The top and the lower section of brake block 5 of steel ball 4, which are provided with, makes the inner side of flywheel casing 1 form confined space with the inner outside of core 2
Enclosing cover 7.
When the flywheel is worked using the present embodiment, flywheel casing 1, which is rotated, drives steel ball 4 along the inner outside of core 2 and flywheel casing 1
The rolling path rolling of steel ball 4 of inner side；When flywheel casing 1 is reversely rotated, brake block 5 promotes brake block under the thrust of spring 6
5, make brake block 5 and the extrusion friction of flywheel casing 1, realize flywheel casing 1 with protecting the automatic clutch of positive frame 3, it is to avoid outside flywheel
The damage rocked space and cause flywheel is produced when shell 1 is inverted.
