Abstract
The utility model provides an eccentric wheel and relates to an improvee structure of the eccentric wheel. The eccentric wheel which is connected through a pin is easy to control the processing accuracy, can avoid the stress concentration. And the eccentric wheel comprises an axial eccentric wheel; and the eccentric wheel is connected with a cross head through a connecting rod. In the main technical proposal, the axis is provided with a protruding table; the protruding table is connected with a middle sleeve arranged between the two eccentric wheels through a pin; and the middle sleeve are connected with the two eccentric wheels on the two sides of the middle sleeve through a bolt.
Description
Technical field:
The utility model relates to the improvement of eccentric wheel structure.
Background technique:
Diaphragm pump power end transmission eccentric wheel structure is it to be rotatablely moved be converted into straight line motion, promotes piston and carries out work; The jig frequency of per minute is more than 42 times, and piston rod bears the impact of alternate load motion.But existing diaphragm pump power end is the eccentric wheel structure form, and its big bevel pinion is connected into the herringbone gear form.Exist following shortcoming: 1, because big or small Gear Processing precision is difficult to guarantee that therefore in use the gap of gear easily produces impact endurance test shock.2, two eccentric fixedly keyways differ 90 ° on axle, and not only axle generation stress is concentrated; And machining accuracy is difficult to guarantee, influenced eccentric normal operation.
The model utility content:
The utility model is exactly at the problems referred to above, the eccentric wheel with the pin connection that a kind of easy assurance machining accuracy is provided, can avoids stress to concentrate.
For achieving the above object, the utility model adopts following technological scheme, the utility model comprises a last eccentric wheel, eccentric wheel links to each other with crosshead by connecting rod, its structure outline axle is provided with boss, boss links to each other with the middle cover between two eccentric wheels by pin, and middle cover links to each other by the eccentric wheel of bolt with both sides.
The beneficial effects of the utility model:
1, be easy to guarantee machining accuracy:
Complicated be connected into herringbone gear because the utility model has been replaced by the middle cover with pin, the utility model is processed easily by big bevel pinion, and easier assurance machining accuracy; Make wobbler action steady simultaneously;
2, avoided stress to concentrate:
Owing to do not spline on axle, thereby the stress that has reduced axle is concentrated; And the intensity and the rigidity of axle have been improved.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of boss of the present utility model with the middle cover combination;
Fig. 3 is that the A of Fig. 2 is to view.
Embodiment:
The utility model comprises eccentric wheel 2 on the axle 5, and eccentric wheel 2 links to each other with crosshead 8 by connecting rod 6, and axle 5 is provided with boss 4, and boss 4 links to each other with the middle cover between two eccentric wheels 21 by pin 3, and middle cover 1 links to each other by the eccentric wheel 2 of bolt 7 with both sides.
Add man-hour, the boss 4 on the axle 5 of the present utility model is installed together with middle cover 1, then, between boss 4 and middle cover 1, hole 9; On hole 9, be fixed with pin 3 again; Can guarantee the concentricity of boss 4 and middle cover 1.
