Description
Technical field
The utility model is related to swinging screen technical fields, and in particular to a kind of rectangular swinging screen vibrator.
Background technology
Existing rectangular swinging screen vibrator is that exciter shaft both ends are equipped with each a set of bearing, and eccentricity balance-weight block is fixed on
On axis, spindle nose is equipped with negative pulley wheel, and bearing block is fixed in babinet.Negative pulley wheel drives shaft rotation dynamic, and axis drives bias to match
Pouring weight rotates.In assembly since the two bearings depth of parallelism is difficult that control is parallel consistent.Long-play can cause bearing wear.From
And bearing use cost is caused to increase, reduce service efficiency.
Invention content
For the above situation, existing rectangular swinging screen vibrator bearing is easy to wear, use cost is high in order to solve, drop
Problem low, service efficiency is low.The utility model provides one kind and can reduce bearing wear degree, reduce cost of use, improve
A kind of rectangular swinging screen vibrator of utilization rate.
Technical solution is：Include spindle nose, the quilt of the vibrator shell, exciter shaft and exciter shaft both ends that are fixed in babinet
Dynamic belt pulley and eccentricity balance-weight block, vibrator shell is interior to be equipped with a set of bearing, and bearing is socketed on exciter shaft, exciter shaft both ends
Spindle nose be separately fixed on babinet, negative pulley wheel and eccentricity balance-weight block are each attached on vibrator shell, and negative pulley wheel can
The rotation of vibrator shell, vibrator shell is driven to drive eccentricity balance-weight block rotation.
Preferably, spindle nose is fixed by screws on babinet.
Preferably, negative pulley wheel is fixed by screws in vibrator shell top.
Preferably, eccentricity balance-weight block is fixed by screws in lower end in vibrator shell.
The utility model provides a kind of rectangular swinging screen vibrator, has the beneficial effect that compared with prior art：By vibrator
Axis both ends spindle nose is fixed on babinet, and negative pulley wheel and eccentricity balance-weight block are each attached on vibrator shell.Make exciter shaft not
In the case of dynamic, negative pulley wheel can drive vibrator shell to rotate, and vibrator shell drives eccentricity balance-weight block rotation.When can avoid long
Between operation can cause bearing wear.Vibrator service efficiency is improved, cost of use is reduced.
Description of the drawings
Fig. 1 the utility model provides a kind of rectangular swinging screen exciter structure schematic diagram.
In figure：1 babinet, 2 vibrator shells, 3 exciter shafts, 4 spindle noses, 5 negative pulley wheels, 6 eccentricity balance-weight blocks, 7 bearings, 8
Screw.
Specific implementation mode
The utility model is described in further detail presently in connection with attached drawing.Attached drawing is the schematic diagram of simplification, only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
Embodiment one, as shown in Figure 1, a kind of rectangular swinging screen vibrator, including be fixed in babinet 1 vibrator shell 2,
Spindle nose 4, negative pulley wheel 5 and the eccentricity balance-weight block 6 at 3 both ends of exciter shaft 3 and exciter shaft.It is equipped in vibrator shell 2 a set of
Bearing 7.Bearing 7 is socketed on exciter shaft 3.The spindle nose 4 at 3 both ends of exciter shaft is fixed on by screw 8 on babinet 1 respectively.
Negative pulley wheel 5 and eccentricity balance-weight block 6 are each attached on vibrator shell 2.Negative pulley wheel 5 can drive vibrator shell 2 to rotate.Swash
The device shell 2 that shakes drives eccentricity balance-weight block 6 to rotate.In the case of keeping eccentric shaft motionless, negative pulley wheel can drive vibrator shell to rotate,
Vibrator shell drives eccentricity balance-weight block rotation, to generate vibration.Avoidable long-play can cause bearing wear.It improves and swashs
It shakes device service efficiency, reduces cost of use.
Embodiment two, on the basis of embodiment one, further, spindle nose 4 is fixed on by screw 8 on babinet 1.Passive skin
Belt wheel 5 is fixed on 2 top of vibrator shell by screw 8.Eccentricity balance-weight block 6 is fixed on lower end in vibrator shell 2 by screw 8.
The above embodiments are merely examples for clarifying the description, and does not limit the embodiments.For institute
For the those of ordinary skill in category field, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.Among the protection domain that variation or variation extended from this are created still in the utility model.
