Degree, improves the support situation of shifting axle, it is therefore prevented that because rotating or eccentric wear produced by axial float.
2. overall eccentric processing technique is simple, and part is few, and big chute access section cross-sectional area strengthens,
Enhance the bearing capacity of hollow axle.
3. connecting rod back-up ring is arranged on overall eccentric, can radially move and subtract together with overall eccentric
Few connecting rod eccentric wear, worm gear and the axle of worm screw generation, equipped with thrust ball bearing, can be reduced in connecting rod back-up ring side
To impulsive force.
Thus substantially increasing dosing pump bearing capacity big, measuring accuracy is high, and service life is long.
Accompanying drawing explanation
Fig. 1 is the dosing pump structural representation of entirety throw of eccentric governor motion of the present invention.
Fig. 2 be entirety throw of eccentric governor motion of the present invention dosing pump in the structural representation of overall eccentric
Figure.
Fig. 3 is the structural representation of the dosing pump hollow mandrel of entirety throw of eccentric governor motion of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is described in detail.
Slider bar travel governor motion as shown in Figure 1, including tune amount screw mandrel 1, shifting axle 2, hollow axle
3, connecting rod 5, overall eccentric 7, worm gear 8, worm screw 9, slide bar 10, described tune amount screw mandrel 1
One end can be connected the most in relative rotation with shifting axle 2, described shifting axle 2 is inserted in hollow axle 3
In, described shifting axle 2 has skewed slot 2-1, skewed slot 2-1 is provided with slide block 6, described is hollow
Being arranged with overall eccentric 7 on axle 3, described overall eccentric 7 is fixed with connecting rod 5, described
Connecting rod 5 is connected with slide bar 10, and described hollow axle 3 is socketed with worm gear 8, described worm gear 8
Engage with worm screw 9.
Described tune amount screw mandrel 1 uses locking after round nut 14, locking plate 17, angular contact bearing 15
Nut 16 is rotatably mounted to one end of shifting axle 2.So arrange and can improve tune amount screw mandrel 1 He
Axiality between shifting axle 2, improves the support situation of shifting axle 2, it is therefore prevented that because rotating or axial
Eccentric wear produced by play.
Between described overall eccentric 7 and connecting rod 5, there is needle bearing 12.
It is provided with connecting rod back-up ring 4 outside described connecting rod 5 and needle bearing 12.
Described connecting rod back-up ring 4 opposite side is provided with thrust ball bearing 13.
Described hollow axle 3 two ends are provided with conical roller bearing 18 and conical roller bearing 19.
Connecting rod back-up ring 4 is arranged on overall eccentric 7, can do and radially move together with overall eccentric 7
Dynamic minimizing connecting rod 5 eccentric wear, worm gear 8, equipped with thrust ball bearing 13, can be reduced in connecting rod back-up ring 4 side
The axial impact force produced with worm screw 9.
Described tune amount screw mandrel 1 is provided with adjusting handle 21.
Such as Fig. 2. and it is provided with the little chute 3-3 of symmetry on the hollow axle 3 as described in shown in 3 concurrently with big
Chute 3-1, offers through warp-wise through hole 3-3 at described little chute 3-2；Described is overall inclined
Heart wheel 7 is two layers of staged frustum cone structure, and one layer of ladder 7-2 have the biggest slide opening 7-21, two
Layer ladder 7-1 is provided with eccentric orfice, and described eccentric orfice one outer is provided with radially little slide opening 7-11, institute
The big slide opening 7-21 and the little slide opening 7-11 that state are through, and two layers of described ladder side are provided through bias
The slide block installing hole 7-12 in hole.
Described slide block 6 passes on the slide block installing hole 7-12 on overall eccentric 7, hollow axle 3
Skewed slot 2-1 on radial direction through hole 3-3 and shifting axle 2 is located on overall eccentric 7.
Operation principle is as follows:
Motor drives hollow axle 3 to rotate by worm gear 8, worm screw 9, and hollow axle 3 drives overall inclined simultaneously
Heart wheel 7, connecting rod 5, slide bar 10 do linear reciprocating motion.When tune amount screw mandrel 1 axially-movable, move
Moving axis 2 also axially moves simultaneously, owing to slide block 6 and overall eccentric 7 can not axially move,
In the skewed slot of shifting axle 3, slide block moves radially, drives overall eccentric 7 can only do radial motion, makes
Its eccentric throw is changed, and the movement travel of slide bar 10 changes therewith.
