Abstract
The utility model is related to a kind of variable eccentric for fatigue tester, and it mainly includes eccentric wheel body, eccentric block, balancing weight, left-right rotary screw mandrel, end cap A, end cap B；Through in a left-right rotary screw mandrel, and in the dovetail groove of eccentric wheel body, end cap A and end cap B is located at the dovetail groove two ends of eccentric wheel body to limit the axial movement of left-right rotary screw mandrel for eccentric block and balancing weight.Four square holes for turning left-right rotary screw mandrel one end by spanner rotate left-right rotary screw mandrel, eccentric block is moved so as to adjust eccentric throw in the dovetail groove of eccentric wheel body；Corresponding balancing weight also can be under the rotation of left-right rotary screw mandrel towards the direction movement that eccentric block is opposite, so as to reach dynamically balanced purpose simultaneously.
Description
Technical field
The utility model is related to a kind of eccentric wheel installed in Mechanical Fatigue Test Machine, and more particularly to one kind needs regulation
Eccentric throw, but with dynamically balanced eccentric wheel, the eccentric wheel can be widely applied to various plant equipment.
Background technology
Motor is rotated by transmission device band movable eccentric wheel in Mechanical Fatigue Test Machine, is straight by convert rotational motion
Line is moved back and forth.Conventional eccentric wheel is the ability with regulation eccentric throw, it is impossible to reach dynamic balancing function, such that
Machinery produces strong vibrations and substantial amounts of noise.
Utility model content
Main purpose of the present utility model is to provide one kind to be needed to adjust eccentric throw, and the bias with Self-balancing
Wheel.
In order to solve the above-mentioned technical problem, the utility model includes installed in the eccentric wheel of Mechanical Fatigue Test Machine：Partially
Heart wheel body, eccentric block, balancing weight, left-right rotary screw mandrel, end cap A, end cap B, it is characterised in that：Eccentric block and balancing weight through
In a piece left-right rotary screw mandrel, and in the dovetail groove of eccentric wheel body, end cap A and end cap B is located at the dovetail of eccentric wheel body
Groove two ends are limiting the axial movement of left-right rotary screw mandrel.
The pitch at wherein told left-right rotary screw mandrel two ends is identical, and two tops of screw mandrel are provided with four square holes and are rotated in order to spanner
Left-right rotary screw mandrel；There is certain gap between the eccentric block told and the lower end of balancing weight and eccentric wheel body, it is more held
It is easy to install；There is a screwed hole end cap A upper ends told, for mounting screw with fixed screw, in order to limit left-right rotary screw mandrel
Circumferential movement.
The utility model has the advantage of：Eccentric wheel of the present utility model reaches tune by the eccentric block slided on screw mandrel
Save the purpose of eccentric throw；And the dynamic balancing for then realizing eccentric wheel of corresponding balancing weight.
Brief description of the drawings
Fig. 1 is the utility model overall structure schematic three dimensional views.
Fig. 2 is a kind of front view of variable eccentric for fatigue tester of the utility model.
Fig. 3 is a kind of full sectional view of variable eccentric for fatigue tester of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to figs. 1 to Fig. 3, the utility model provides a kind of variable eccentric for fatigue tester, and it includes：Partially
Heart wheel body（4）, eccentric block（5）, balancing weight（2）, left-right rotary screw mandrel（3）, end cap A（1）, end cap B（6）, it is characterised in that：Partially
Heart block（5）With balancing weight（2）Through a left-right rotary screw mandrel（3）In, and positioned at eccentric wheel body（4）Dovetail groove in, end
Lid A（1）With end cap B（6）Positioned at eccentric wheel body（4）Dovetail groove two ends limiting left-right rotary screw mandrel（3）Axial movement.
Further, left-right rotary screw mandrel（3）The pitch at two ends is identical, and two tops of screw mandrel are provided with four square holes in order to spanner
Rotary screw rod.
Further, eccentric block（5）And balancing weight（2）Lower end and eccentric wheel body between there is certain gap,
Make it easier to install.
In order that eccentric wheel operationally eccentric throw is constant, therefore in end cap A（1）There is a screwed hole upper end, for installing spiral shell
Follow closely with fixed screw, in order to limit left-right rotary screw mandrel（3）Circumferential movement.
During specific works, if to adjust eccentric throw can turn left-right rotary screw mandrel with spanner（3）The four square holes rotation of one end
Screw mandrel, makes eccentric block（5）In eccentric wheel body（4）Dovetail groove in move so as to adjust eccentric throw；It is simultaneously corresponding
Balancing weight（5）Also can be in left-right rotary screw mandrel（3）Rotation under towards eccentric block（5）Opposite direction movement, so as to reach dynamic balancing
Purpose.
Claims (4)
