It is located in the roller outer ring to denticle, roller, flat spring, the roller is touched with the roller outer ring；In the unidirectional tooth
An isolation adjusting gasket and a ball bearing are put on the both ends of mandrel respectively, the isolation adjusting gasket is located at institute
It states between unidirectional denticle and ball bearing；The shelves cover board is embedded in the inside of the belt hub cap, and the ball bearing is located at
Between the isolation adjusting gasket and shelves cover board.
Further, one end of the unidirectional tooth core axis extends to outside the belt hub cap, in the unidirectional tooth core axis
A dustproof cover is covered on the other end.
Further, the unidirectional denticle tilts and is arranged on the outer wall of the unidirectional tooth core axis at equal intervals.
Further, there are six the unidirectional denticles,
Further, the unidirectional tooth core axis, roller outer ring, roller are made of Steel material.
In conclusion by adopting the above-described technical solution, the utility model compared with prior art, has the advantage that
The one-way belt sheave shell of the utility model and unidirectional tooth core shaft clutch general assembly have combined list more accurate
To the concentricity and deflection degree of belt pulley, service life is substantially increased.Unidirectional tooth core axis, the flat spring, rolling of the utility model
The setting of column and roller outer ring can more smoothly support circulation, make roller outer ring and roller and unidirectional denticle uniform force,
More coaxial, balance, one-way locking is more firm, and unidirectional skidding is more smooth.

Specific embodiment
Specific embodiment of the present utility model is further described in detail with reference to the accompanying drawing.
Referring to Figure 1~7, the utility model provides a kind of single-way belt pulley of automobile generator, including belt hub cap
1, unidirectional tooth core axis 2, ball bearing 3, roller outer ring 4, isolation adjusting gasket 5, shelves cover board 6.
Multiple unidirectional denticles 7 are fixed on the outer wall of unidirectional tooth core axis 2, any unidirectional denticle 7 is connected with a flat spring 8
It connects, any flat spring 8 is connected with a roller 9.The unidirectional inclination of denticle 7 and the outer wall that unidirectional tooth core axis 2 is set at equal intervals
On, there is a protrusion 11 between two neighboring unidirectional denticle 7.Preferably, there are six unidirectional denticles 7.
The outside that roller outer ring 4 is assembled in unidirectional tooth core axis 2 forms unidirectional tooth core shaft clutch assembly, unidirectional denticle 7, rolling
Column 9, flat spring 8 are located in roller outer ring 4, and roller 9 is touched with roller outer ring 4.On being covered respectively on the both ends of unidirectional tooth core axis 2
Adjusting gasket 5 is isolated between unidirectional denticle 7 and ball bearing 3 in one isolation adjusting gasket 5 and a ball bearing 3.Shelves cover board
The inside of 6 insertion belt hub caps 1, ball bearing 3 are located between isolation adjusting gasket 5 and shelves cover board 6.
One end of unidirectional tooth core axis 2 extends to outside belt hub cap 1, is covered with one on the other end of unidirectional tooth core axis 2
Dustproof cover 10.Dustproof cover 10 can prevent extraneous dust, sandstone, greasy dirt etc. from entering inside one-way belt sheave, make its isolation, prolong
Long life.
The effect of the utility model shelves cover board 6 is that the inner components of belt hub cap 1 are fixed on outside one-way belt sheave
It does not swing on certain position within shell 1, prevents it from falling off.
The effect of ball bearing 3 is to be fixed on both ends and the support mandrel 360 degree rotation of unidirectional tooth core axis 2.Isolation is adjusted
The effect of gasket 5 is that ball bearing 3 is isolated with unidirectional denticle 7, and protects when roller 9 and flat spring 8 are slided it；
The position and gap between inner components are adjusted simultaneously, thick, thin isolation adjusting gasket 5 can be realized by replacement.
Referring to Figure 1, belt hub cap 1 is driven by automobile belt connection, when unidirectional denticle 7 is motionless, roller outer ring 4
When rotating clockwise, angle of the roller 9 under the extension tension force effect of flat spring 8 in unidirectional denticle 7 with the formation of roller outer ring 4
Place, roller outer ring 4 drive roller to force tightly to angle, form continuous occlusive state, with regard to this continuous locking.When 4 inverse time of roller outer ring
When needle rotates, roller outer ring 4 drives roller 9 to flat spring 8 to shrink, and roller outer ring 4 and roller 9 will generate dynamics relaxation at this time,
Continuous discrete state is formed, with regard to this skidding 360 degree rotation.One-way clutch effect is realized by the above method.
The utility model is assembled into two-body combination, i.e. one-way belt sheave shell 1 and unidirectional tooth core shaft clutch always in groups
Dress combines, it is possible to reduce error, to ensure that concentricity and deflection degree.
The one-way belt sheave shell 1 of the utility model and unidirectional tooth core shaft clutch general assembly have combined list more accurate
To the concentricity and deflection degree of belt pulley, actual measurement tolerance is 0.05mm, substantially increases service life.The utility model it is unidirectional
Tooth core axis 2, unidirectional denticle 7, flat spring 8, roller 9 and the setting of roller outer ring 4 can more smoothly support circulation, make roller
Outer ring 4 and roller 9 and 7 uniform force of unidirectional denticle, more coaxially, balance, and one-way locking is more firm, unidirectionally skid more suitable
Freely.
Embodiment described above is merely to illustrate the technical idea and feature of the utility model, and its object is to make ability
Technical staff in domain can understand the content of the utility model and implement accordingly, cannot be only practical to limit with the present embodiment
Novel the scope of the patents, i.e., it is all according to same changes or modifications made by the revealed spirit of the utility model, it still falls in practical
In novel the scope of the patents.
