Specific embodiment
Referring to figs. 1 to Fig. 2, details are as follows for the structure feature for the raceway that rubs to this sprocket wheel Double End：
A kind of sprocket wheel Double End friction raceway, including pedestal 1, transmission shaft 2 and sprocket wheel 3,2 both ends of transmission shaft pass through bearing
4 and bearing cap 5 be set on the top of pedestal 1, the sprocket wheel 3 is socketed on 5 outside of bearing cap of 2 one end of transmission shaft；The sprocket wheel 3 it is another
One end is equipped with regulating member 7 in 2 periphery socket spring 6 of transmission shaft, the other end of the spring 6；Described 3 one end of sprocket wheel and transmission
The first friction plate 81 is equipped on axis 2 between corresponding bearing cap 5, is rubbed between the other end of the sprocket wheel 3 and spring 6 equipped with second
Pad 82,81 and second friction plate 82 of the first friction plate are fixed on transmission shaft 2.
The sprocket wheel Double End rubs raceway in action process, by the collapsing length of 7 adjustment spring 6 of regulating member, after
And change axial force suffered by sprocket wheel 3, change the first friction plate 81 and the second friction plate 82 and the frictional force at 3 both ends of sprocket wheel, realize
Sprocket wheel 3 and transmission shaft 2 be mutually disengaged or the state effect of secure fit, realize the autobiography of sprocket wheel 3 or drive transmission shaft 2 common
The state of rotation；It can be realized during sprocket wheel 3 persistently rotation, transmission shaft 2 can realize stopping at any time or common with sprocket wheel 3
The action effect of rotation.
When the machining position on automobile packing line needs processing component to realize transmission action, at this point, reducing stopper 9, adjust
Regulating member 7 is saved, makes its compressed spring 6；The elastic force of spring 6 compressed at this time makes the second friction plate in 6 other end of spring
82nd, 3 and first friction plate 81 of sprocket wheel is mutually adjacent to, you can increase sprocket wheel 3 rubs with first friction plate 81 at its both ends and second
Frictional force between pad 82；When regulating member 7 reaches suitable location, the elastic force for making spring 6 is sufficiently large, you can realizes sprocket wheel 3
Realized between first friction plate 81 and the second friction plate 82 at its both ends it is opposing stationary, since the first friction plate 81 and second rubs
Pad 82 is fixed on transmission shaft 2, i.e. the first friction plate 81 and the second friction plate 82 drive transmission shaft 2 with sprocket wheel 3 simultaneously
Rotation realizes that sprocket wheel 3 drives 2 common action of transmission shaft, and automobile dispenses processing component on line and realizes transmission action.
When the machining position on automobile packing line needs processing component to temporarily cease transport action, regulating member 7 is adjusted, is made
The spring 6 of compression gradually restores；The elastic force of spring 6 is gradually reduced at this time, you can reduces sprocket wheel 3 and first friction plate at its both ends
81 and the second frictional force between friction plate 82；When regulating member 7 reaches suitable location, the elastic force of spring 6 is sufficiently small, you can real
It is opposite between existing sprocket wheel 3 and first friction plate 81 and the second friction plate 82 at its both ends to slide；It is acted at this point, starting stopper 9,
Stopper 9 is made to increase, the inertia for preventing transmission shaft 2 by stopper 9 rotates, while the first friction plate 81 and the second friction plate 82
Static with transmission shaft 2, sprocket wheel 3 continues to keep rotation, realizes that sprocket wheel 3 individually rotates, the state that transmission shaft 2 stops operating, automobile
Processing component, which can be realized, on packing line temporarily ceases action.
As the preferred embodiment of the present invention, with reference to shown in Fig. 1 to 2；
Specifically, in one of which embodiment, the regulating member 7 uses adjusting nut, and the corresponding end of the transmission shaft 2
End is equipped with external screw thread, and the external screw thread of 2 end of transmission shaft is adapted with adjusting nut；Wherein, the adjusting nut is outer
Diameter is more than the diameter of spring 6；Adjusting nut can be passed through by further ensuring that（Regulating member 7）To the extruding degree of spring 6, change
The elastic force of spring 6 realizes opposing stationary or sliding mode the phase co-conversion between sprocket wheel 3 and transmission shaft 2.
Specifically, in another embodiment, the regulating member 7 uses adjusting bolt, and the correspondence of the transmission shaft 2
End is equipped with threaded hole along axis, and the threaded hole of 2 end of transmission shaft is adapted with adjusting bolt；Wherein, the adjusting spiral shell
The nut outer diameter of bolt is more than the diameter of spring 6；Adjusting bolt can be passed through by further ensuring that（Regulating member 7）Nut to spring
6 extruding degree changes the elastic force of spring 6, realizes opposing stationary or sliding mode mutual between sprocket wheel 3 and transmission shaft 2
Transformation.
To further ensure that 3 both ends institute stress of sprocket wheel is identical；First friction plate 81 at 3 both ends of sprocket wheel and the second friction
Piece 82 is symmetrical arranged；So as to avoid 3 both ends force unbalance of sprocket wheel, ensure the service life of sprocket wheel 3.
Specifically, 3 both ends of sprocket wheel are arranged with indent cascaded surface 31, and described in the edge that transmission shaft 2 connects
One friction plate 81 and the second friction plate 82 are symmetrically positioned in the indent cascaded surface 31 at 3 both ends of sprocket wheel；Further realize the first friction
81 and second friction plate 82 of piece is stablized relatively with the cooperation of the end positions of sprocket wheel 3 respectively, reduces to the first friction plate 81 and second
The abrasion of friction plate 82 ensures service life.
For be further ensured that the first friction plate 81 and the second friction plate 82 and 2 position of transmission shaft stablize relatively and first
81 and second friction plate 82 of friction plate and sprocket wheel 3 be opposing stationary or during sliding mode, to the first friction plate 81 and the second friction plate
82 abrasion is minimum；First friction plate, 81 and second friction plate 82 is symmetrical with 2 axis of transmission shaft and is equipped with horizontal U-lag
83, limited post 21 is respectively equipped with corresponding to horizontal 83 position of U-lag on 2 lateral wall of transmission shaft, and the limited post 21
Diameter is adapted respectively with the horizontal U-lag 83 on the first friction plate 81 and the second friction plate 82；So as to ensure the first friction
81 and second friction plate 82 of piece is relatively fixed with transmission shaft 2 while connect, and ensures the first friction plate 81 and the second friction plate 82
It is bonded with the stabilization of 3 rubbing surface of sprocket wheel, avoids causing to rub since the position of the first friction plate 81 and the second friction plate 82 is unstable
Increase is wiped, reduces the frictionally damage to the first friction plate 81 and the second friction plate 82 to the greatest extent.
To improve the service life of the first friction plate 81 and the second friction plate 82, its wearability is improved, it is antifatigue to enhance its
Performance；First friction plate, 81 and second friction plate 82 uses polyformaldehyde（POM）Material makes；Thus greatly reduce chain
The mutual sliding friction between the rigid bearing lid 5 corresponding on transmission shaft 2 of 3 end faces is taken turns, further reduces the mill of the sprocket wheel 3
Damage saves financial cost.
The present invention provides a kind of sprocket wheel Double End friction raceway, simple in structure, easily manufactured, can be in existing transmission shaft
On the basis of be improved, so as to reduce repacking cost；During sprocket wheel persistently rotates, transmission shaft can realize at any time stop or
With the co-rotational action effect of sprocket wheel；The friction raceway reduces the abrasion of the sprocket wheel, improves service life, save it is economical into
This, reduces energy consumption, applied widely, easy to utilize.
