Description
1, technical field
The utility model relates to pneumatic element, refers to a kind of directed gas vibrator of gear-engaged type that is used for vibratory sieve equipment especially.
2, background technology
The structure of traditional vibratory sieve is as shown in Figure 1, comprises screen frame 01, is located at the screen cloth that has mesh 02 on the screen frame 01, and is fixed on the vibration source 03 on the screen frame 01.Vibration source more than 03 adopts ultrasonic vibrator, but the ultrasonic vibrator price is higher.
When existing gas vibrator was used on the miscellaneous equipment, during the motion of gas vibrator drive load, mostly the load movement track was irregular curve, can't realize the motion of the orientation of load, and the idle work of consumption is more, and efficient is lower.
3, utility model content
The purpose of the utility model is to provide a kind of gear type engagement gas vibrator that makes load can realize directional vibration, improves the efficient of gas vibrator, and simplified structure is practiced thrift cost.
The utility model is realized through following technical scheme:
The directed gas vibrator of a kind of gear-engaged type comprises the vibrator housing that has air inlet and exhaust outlet, is provided with die cavity in the inside of vibrator housing; Air inlet and exhaust outlet are communicated with die cavity, minimum a pair of pitch wheel, i.e. left gear and the right gear of being equipped with in the die cavity the inside; Left gear and right gear are installed in respectively on left gear axle and the right gear axle; Through the rolling bearing supporting, rolling bearing is installed on the bearing saddle bore of vibrator housing the inside respectively for left gear axle and right gear axle two ends, and left gear is provided with lightening core and eccentric block; Right gear is provided with lightening core and eccentric block; It is characterized in that: two meshing gears rotate around gear shaft under compressed-air actuated thrust, and the eccentric force during rotation is mutual superposition on the direction of vibration force output, make the vibration force of vibrator output reach maximum; And the eccentric force of two meshing gears is partly or entirely cancelled out each other on the opposite direction of power output; Vibration force output approaches zero in that this side up, makes load obtain the vibration of orientation, maximum amplitude thus, improves the efficient of vibrator.
Described left gear and right gear are a pair of intermeshed gear, and tooth-formation of gear is straight-tooth, helical teeth and herringbone tooth, and the gear number of teeth is 8～25 teeth.
Have 1 lightening core on said each gear at least, have 1 eccentric block at least.
The beneficial effect that the utlity model has:
When the air inlet of compressed air from vibrator housing enters in the near closed hollow ring of gas vibrator; The thrust of gas makes two gears rotate around gear shaft on the two meshed gears flank of tooth, and gear is provided with eccentric block; Gear produces eccentric force when rotated; This eccentric force is cancelled out each other in certain direction, and mutual superposition on another direction makes the vibration force of vibrator output on certain direction, reach maximum.Make load obtain directed vibration thus, simplified structure reduces cost.
Because gear with leaving small gap between the housing inner chamber but can not contact, makes compressed-air actuated leakage rate minimum like this, improve the efficient of vibrator.

The cutaway view of the directed gas vibrator of the gear-engaged type of Fig. 2 the utility model.
Fig. 3 is that the A-A of Fig. 2 analyses and observe a kind of structure chart;
Fig. 4 is that the A-A of Fig. 2 analyses and observe another kind of structure chart.
5, the specific embodiment:
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
Like Fig. 2, Fig. 3, shown in Figure 4; The directed gas vibrator of a kind of gear-engaged type comprises the vibrator housing 1 that has air inlet 11 and exhaust outlet 12, is provided with die cavity 13 in the inside of vibrator housing 1; Air inlet 11 is communicated with die cavity 13 with exhaust outlet 12; Minimum in die cavity 13 the insides a pair of pitch wheel is installed, i.e. left gear 21 and right gear 22, left gear 21 and right gear 22 are installed in respectively on left gear axle 31 and the right gear axle 32; Left gear axle 31 supports through rolling bearing 5 respectively with right gear axle 32 two ends; Rolling bearing 5 is installed on the bearing saddle bore 14 of vibrator housing 1 the inside, and left gear 21 is provided with lightening core 211 and eccentric block 212, and right gear 22 is provided with lightening core 221 and eccentric block 222.
Have 1 lightening core on said each gear at least, have 1 eccentric block at least.
Compressed air enters in the near closed hollow ring of gas vibrator from the air inlet 11 of vibrator housing; The thrust of gas makes two gears rotate around gear shaft on the two meshed gears flank of tooth, is discharged by exhaust outlet 12 again; Gear is provided with eccentric block; Two meshing gears produce eccentric force when rotated, and this eccentric force is mutual superposition on the direction of vibration force output, make the vibration force of vibrator output reach maximum.And the eccentric force of two meshing gears is partly or entirely cancelled out each other on the opposite direction of power output, and vibration force output approaches zero in that this side up.Make load obtain the vibration of orientation, maximum amplitude thus, improve the efficient of vibrator.
Like Fig. 3, shown in Figure 4, gear makes compressed-air actuated leakage rate minimum with leaving small gap between the housing die cavity 13 but can not contact like this, and compressed-air actuated thrust is acted on the gear to greatest extent, and it is maximum that the vibrator delivery efficiency also reaches.
