Abstract
The utility model relates to an improved turbine vibrator structure, which is characterized in that an eccentric rotor is arranged in an air chamber of a base, outer covers are respectively arranged in through grooves on two sides of the base and used for fixing the eccentric rotor, and inner walls of the two through grooves are respectively provided with threads with the same spiraling direction. Therefore, a cutter used for processing the base can be used for machining the two through grooves and the air chamber on the base along the same axis sequentially, the two through grooves and the air chamber share the same axis, service life reduction caused by processing deviation of the axis of a rotating shaft of the eccentric rotor during rotation can be lowered; and furthermore, the rotating direction of the eccentric rotor is opposite to directions of the threads on the inner walls of the two through grooves, so that the outer covers can be combined and fastened with the base more tightly when in rotation of the eccentric rotor, and any of the two outer covers can avoid loosening and falling from the base.
Description
Technical field
The utility model system refers to a kind of different formed eccentric effects of eccentric rotor structure counterweight of utilizing especially about a kind of turbine vibration device structural improvement, makes this eccentric rotor produce the turbine vibration device of vibrating effect when rotating at a high speed.
Background technology
Storage, agitator, pulverizer ... wait device, be stained with for fear of material and stick on wall or be fastened in corner, the slot, generally can on this device, add a turbine vibration device, utilize high pressure draught to drive set rotor in this turbine vibration device with eccentric inertia, this rotor of mat is the vibrative effect of the variation of momentum in rotation process, and then drive the single unit system vibration, reach the purpose of material.
As shown in Figure 4, it is the turbine vibration device (60) of a prior art, its two relative side that lies in a pedestal (61) forms one respectively and wears groove (611), this two is worn between the groove (611) and is connected with an air chamber (612), be provided with an eccentric rotor (62) in this air chamber (612), the axial respectively projection in the two opposite sides of this eccentric rotor (62) forms a rotating shaft (621), distinguishes a sheathed bearing (63) again in this two rotating shaft (621);
Two enclosing covers (64) are located at wearing in the groove (611) of this pedestal (61) respectively, form a groove (641) on the end face of the corresponding pedestal of each enclosing cover (64) (61) inside, for ccontaining one corresponding bearing (63), be to form the screw thread that matches respectively on the outer shroud wall of two of this pedestal (61) the internal ring wall faces of wearing groove (611) and this enclosing cover (64) with relative fixed again.
Wherein, above-mentioned pedestal (61) is when making with machined into, and needing elder generation is that benchmark runs through this pedestal (61) with the internal diameter of this air chamber (612); Then withdrawing is to the place, a side of the contiguous lathe of this pedestal (61), is that benchmark is worn groove (611) to this and done further processing to wear the default internal diameter size of groove (611), and forms screw thread on the internal ring wall face of wearing groove (611); This pedestal (61) that overturns again afterwards makes lathe machine-shaping on the another side of pedestal (61) have another to wear groove (611) and screw thread.
Under above-mentioned processing mode, this pedestal (61) both sides wear groove (611) be easy to just can cause because of the relation of error its axle center not the position at same axial line, thereby influence the position of this two enclosing cover (64), make the rotating shaft (621) that is positioned the last eccentric rotor (62) of this enclosing cover (64) by bearing (63) also can form deflection; Thus, eccentric rotor (62) is under high speed rotating, and its rotating shaft (621) will be because of bearing the fracture easily of great load, damaging.
Moreover two of this pedestal (61) is worn screw thread that groove (611) locates after machining, its around direction be opposite, that is, when this two enclosing cover (64) being locked in this pedestal (61) when going up, this two enclosing cover (64) must be rotated with opposite direction; Thus, when this turbine vibration device (60) in when running, in case this eccentric rotor (62) rotates towards a specific direction, and when driving integral turbine vibrator (60) vibration, wherein will more and more fasteningly combine between an enclosing cover (64) and pedestal (61), another enclosing cover (64) then can be gradually by getting loose on the pedestal (61), even drop.
Summary of the invention
Because the shortcoming of aforementioned prior art, the utility model is improved at the structure of turbine vibration device, the eccentric rotor that uncommon design by this solves the turbine vibration device of prior art damages easily, and the shortcoming that in rotating process, causes an enclosing cover wherein to get loose, drop easily, and make procedure of the present utility model once finish in regular turn along axial line, avoid the clamp tool process of repetition.
In order to reach above-mentioned utility model purpose, the technology that the utility model utilized is: turbine vibration device structure-improved comprises:
One pedestal, form in regular turn between its two relative side be connected one first wear groove, an air chamber and one second is worn groove;
One first enclosing cover, it is to be located at first of described pedestal to wear in the groove, and indent forms a groove on the inner face within the corresponding pedestal;
One eccentric rotor, it is to be located in the air chamber of described pedestal, on the outer shroud wall of described eccentric rotor around forming a plurality of flute profile blades, the axial respectively projection in two opposite sides forms a rotating shaft, the sheathed bearing of difference in described two rotating shafts, wherein a bearing is located in the groove of described first enclosing cover;
One second enclosing cover, it is to be located at second of described pedestal to wear in the groove, and indent forms a groove on the inner face within the corresponding pedestal, the groove of described second enclosing cover can supply ccontaining another bearing, it is characterized in that:
First, second of described pedestal worn and formed respectively with equidirectional on the internal ring wall face of groove around the screw thread that is provided with;
Around forming screw thread, first of the screw thread of described first enclosing cover and described pedestal worn the threads engaged of groove and can be mutually combined on the outer shroud wall of described first enclosing cover;
Around forming screw thread, second of the screw thread of described second enclosing cover and described pedestal worn the threads engaged of groove and can be mutually combined on the outer shroud wall of described second enclosing cover.
The oblique in the same direction extension of each flute profile impeller of above-mentioned eccentric rotor, when this eccentric rotor was driven by air-flow, the rotation direction during first, second enclosing cover locking of its rotation direction and this was identical.
Design by this, when when making this pedestal with machined into, can overturn this pedestal can make in order to the cutter of processing along the machine-shaping in regular turn of same axis have this first to wear groove, air chamber and second is worn groove, make it have identical axle center, the load that the rotating shaft of lowering this eccentric rotor is caused because of the axle center machining deviation when rotating, thereby the service life of improving the turbine vibration device.
In addition, more can make this first wear groove and second and wear the screw thread at groove place and put with identical directional ring winding, when the rotation direction when first, second enclosing cover of rotation direction and this of this eccentric rotor locks is identical, two to wear within the groove on the wall hand of spiral opposite with this for this eccentric rotor direction of rotation, so when eccentric rotor rotate to produce, will make more and more fastening combination the between this enclosing cover and pedestal, reach and prevent that wherein arbitrary enclosing cover is by the purpose that gets loose on the pedestal, drops.
