Dry through hole, after two wheel hub clampings, two through holes are interconnected to form passage, and positioning pin is plugged with the passage.
Using the above scheme, when the wherein row sprocket tooth abrasion in sprocket wheel is more serious, it is only necessary to by serious wear
A wheel hub replaced, solve the problems, such as to need replacing whole sprocket wheel, reduce the waste of resource, reduce enterprise and exist
Cost in production link.In addition, utilize the cooperation of card slot and fixture block, simple in structure, replacement easy to disassemble；Two through hole connections
Into a passage, it is threaded through at the same time in two different wheel hubs easy to a positioning pin, strengthens the firm of two wheel hubs clamping
Property, adds the stability of sprocket wheel entirety.
More preferably：The through hole is arranged on the interval location of card slot and fixture block.
Using the above scheme so that the position that positioning pin is plugged in two wheel hubs is evenly distributed, and positioning pin is to two
Wheel hub it is spacing more uniformly, contribute to increase wheel hub connect and fix after stability.
More preferably：Two clamping rings are clamped to form torus, and the outer end of the torus is provided with rubber ring.
Using the above scheme, rubber ring can use the preferable material of wearing coefficient, when chain is connected on sprocket wheel, rubber ring
Outer end face abutted with chain, cushioning effect is played to chain, help to reduce chain and chain gear transmission caused by noise, be
A good working environment is built in production.
More preferably：The both ends of the rubber ring are connected on the inner wall of two sprockets.
Using the above scheme, rubber ring forms a protective barrier to clamping ring, prevents the impurity in the sprocket wheel external world from rubber
Gap between ring and sprocket enters the wedging position of wheel hub so that the clamping of wheel hub is more bonded.
More preferably：The circumferentially disposed some abutting blocks of outer circumferential surface of the rubber ring, the abutting block and rubber ring
It is smooth excessive.
Using the above scheme, when chain is engaged on sprocket wheel, abuts block and carry out point contact with chain, reduce chain and rubber
The contact area of rubber ring, transmission of the rubber ring to chain is also reduced on the premise of noise abatement and is hindered.
More preferably：Teeth groove is formed between the sprocket, the abutting block is between two opposite teeth groove
And higher than the slot bottom of teeth groove.
Using the above scheme, abut block the dust impurity in teeth groove is stopped, prevent sprocket wheel outside impurity along
Teeth groove arrives at rubber ring, to reduce the accumulation of impurity on rubber ring so that the abrasion of chain wheel and rack is reduced, and adds sprocket wheel
Service life.
More preferably：The outer circumferential surface of the clamping ring is uniformly provided with locating slot, the inner peripheral surface of the rubber ring this
It is provided with the locating piece being connected in locating slot.
Using the above scheme, locating piece is connected in locating slot, spacing to rubber ring progress, prevents rubber ring from being passed in chain
Rotate in a circumferential direction when dynamic and make it that abutting block deviates teeth groove, while add the stability of rubber ring.
More preferably：Side of the teeth groove away from rubber ring is provided with guide groove；One end of the guide groove with
Teeth groove connects, and the other end is abutted with the outer surface of wheel hub.
Using the above scheme, the dust impurity outside sprocket wheel can be slided as the transmission of chain and sprocket wheel is oriented to along sprocket
Enter in teeth groove, the guide groove that one end is connected with teeth groove helps the dust impurity slid in teeth groove being directed to discharge, reduces
The abrasion of sprocket wheel and chain, adds the service life of sprocket wheel.
More preferably：The inner peripheral surface of the wheel hub circumferentially offers some keyways.
Using the above scheme, the setting structure of keyway is simple, coordinates when being socketed in bent axle easy to timing sprocket with spin-ended key
Use, to realize the rotation of timing sprocket.
In conclusion the utility model has the advantages that：
By setting the wheel hub of dislocation clamping, the sprocket wheel odontotripsis for solving sprocket wheel side in use is more serious
The problem of then needing replacing whole sprocket wheel, reduces the waste of resource, reduces production cost；Noise reduction is played in the setting that rubber changes
Effect, for production build a good working environment.
