Lean on, but when operating between it is long just occur that double eccentric wheel loosens the problem skidded or move left and right on main shaft and occurs, make
Inaccurate into positioning, transmitting torque is unreliable so that produces between double eccentric wheel and main shaft and greatly damages, and affects equipment work
Stability.
Therefore, there is positioning inaccurately and transmitting torque can not in the fixation between current jacquard main shaft and double eccentric wheel
The problem leaned on.
Utility model content
The purpose of this utility model is, there is provided a kind of main shaft of jacquard and double eccentric wheel attachment structure, and it has fixed
The characteristics of position is accurately and transmitting torque is reliable.
The technical solution of the utility model：A kind of main shaft of jacquard and double eccentric wheel attachment structure, including main shaft, main shaft
Upper Jing keys are fixed with double eccentric wheel, and a pair of anchor ears are additionally provided with main shaft, and a pair of anchor ears are respectively positioned at the both sides of double eccentric wheel.
In the main shaft and double eccentric wheel attachment structure of aforesaid jacquard, the main shaft is provided with keyway, a part for key
It is fastened in keyway.Enable to key fixed firm on main shaft.
In the main shaft and double eccentric wheel attachment structure of aforesaid jacquard, draw-in groove is provided with the axis hole of the double eccentric wheel,
Another part of the key is fastened in draw-in groove.Double eccentric wheel being accurately positioned in main shaft circumference can be preferably realized, realizes turning round
The reliable delivery of square.
In the main shaft and double eccentric wheel attachment structure of aforesaid jacquard, draw-in groove is provided with the axis hole of the anchor ear, it is described
Another part of key is fastened in draw-in groove.Anchor ear can preferably be realized in the circumferential positioning of main shaft, and then can be preferably real
Existing double eccentric wheel being accurately positioned main shaft axial direction, prevents movement of the double eccentric wheel on main shaft, it is also possible to be main shaft to it is double partially
Heart wheel transmits reliable moment of torsion and plays auxiliary potentiation.
In the main shaft and double eccentric wheel attachment structure of aforesaid jacquard, the key is flat key.Facilitate main shaft with double bias
Take turns and be fixedly connected with solid and reliable between anchor ear.
In the main shaft and double eccentric wheel attachment structure of aforesaid jacquard, the anchor ear Jing screws are fixed on main shaft.Energy
It is enough further to realize solid and reliable fixation of the anchor ear on main shaft.
Compared with prior art, this utility model realizes that double eccentric wheel is dual on main shaft by key and a pair of anchor ears
It is fixed, realized by key double eccentric wheel in main shaft last week being accurately positioned upwards, prevent double eccentric wheel from skidding on main shaft, and
Reliable moment of torsion is transmitted for double eccentric wheel；Double eccentric wheel being accurately positioned on axial direction on main shaft is realized by a pair of anchor ears,
Prevent double eccentric wheel from moving left and right on main shaft.Therefore, the characteristics of this utility model has registration and reliable transmitting torque.
Description of the drawings
Fig. 1 is fit structure schematic diagram of the present utility model；
Fig. 2 is fit structure exploded view of the present utility model.
Labelling in accompanying drawing for：1- main shafts, 2- keys, 3- double eccentric wheels, 4- anchor ears, 5- keyways, 6- draw-in grooves, 7- screws.
Specific embodiment
This utility model is further described with reference to the accompanying drawings and examples, but is not intended as to this utility model
The foundation of restriction.
Embodiment.A kind of main shaft of jacquard and double eccentric wheel attachment structure, are constituted as depicted in figs. 1 and 2, including main shaft
1, Jing keys 2 are fixed with double eccentric wheel 3 on main shaft 1, and a pair of anchor ears 4 are additionally provided with main shaft 1, and a pair of anchor ears 4 are located at respectively double bias
The both sides of wheel 3.The main shaft 1 is provided with keyway 5, and a part for key 2 is fastened in keyway 5.At the axis hole of the double eccentric wheel 3
Draw-in groove 6 is provided with, another part of the key 2 is fastened in draw-in groove 6.Draw-in groove 6 is provided with the axis hole of the anchor ear 4, the key 2
Another part is fastened in draw-in groove 6.The key 2 is flat key.The Jing screws 7 of the anchor ear 4 are fixed on main shaft 1.The screw 7 has
Four, upper and lower each two are fixed on a pair of anchor ears 4 on main shaft 1.
Utility model works principle is：
In the keyway 5 that key 2 is stuck on main shaft 1, now also a part for key 2 is located at the outside of keyway 5, by double bias
Wheel 3 is set on main shaft 1, and the ledge of key 2 is fastened in the draw-in groove 6 at the axis hole of double eccentric wheel 3, completes double eccentric wheel
3 first times on main shaft 1 were fixed, and then respectively two anchor ears 4 were set on main shaft 1 positioned at the both sides of double eccentric wheel 3, and
The ledge of key 2 is fastened in the draw-in groove 6 arranged at the axis hole of anchor ear 4, adjustment anchor ear 4 clamps double eccentric wheel 3, then makes
Anchor ear 4 is completely fixed in the corresponding screw arranged on main shaft 1 with screw 7, is completed a pair of anchor ears 4 and double eccentric wheel 3 is being led
