Abstract
The utility model provides a cast steel or cast iron coupler for an electric dust remover. The cast steel or cast iron coupler is composed of a motor rotating shaft, a coupler body and an electroceramics rotating shaft, and is characterized in that a key groove, an inner round through hole and a U-shaped groove are formed in the coupler body. As optimization, the coupler is made of cast steel or cast iron.
Description
Technical field
The utility model relates to a kind of electric cleaner, relates in particular to a kind of electric cleaner cast steel ironware coupling.
Background technique
Cathode rapping part on electric cleaner is also one of parts of most critical in electric cleaner, wherein the reducing motor of cathode rapping device is arranged on electric cleaner top mostly, by coupling transmission of power electroceramics rotating shaft and the vertical pivot to cathode rapping device, then give rapping shaft by vertical pivot and big or small pinwheel transmission of power.Common coupling generally adopts round steel bar to make, and needs size, inner circle, upper and lower two end faces, rounding, and adopt milling machine to mill out U-groove bevel, then adopt slotting machine to insert out keyway, be gold machining part.Be materials waste on the one hand, the coupling of 4 kilograms needs the steel more than 7 kilograms; On the other hand, whole product all adopts gold machining to be shaped, and processing cost is quite high; The effect in fact using is unsatisfactory, whole gold machining part directly mails to on-the-spot installation, appearance is unshielded, get rusty seriously in scene, make coupling together with motor rotation axis rust, can not fall along with the wearing and tearing of supporting disk, occur the situation of the pin of the U-groove bevel mouth scratch porcelain axle of coupling, easily cause electroceramics rotating shaft to damage.
The rotating speed of reducing motor is quite slow in fact; only has per minute 1 right side of turning left; the requirement of strength of coupling and required precision are not very high yet; the axle sleeve of the electroceramics rotating shaft being connected with it is also book relatively of ironcasting thickness; gap between them is quite large; be that coupling can fall along with the wearing and tearing of supporting disk and it needs most, be linked together with electroceramics rotating shaft all the time, not only protected electroceramics rotating shaft but also guaranteed the normal operation of electric cleaner.
Thereby can redesign the coupling of said structure, under the prerequisite that meets bearing load, simplify production technology, further save cost of production.
Model utility content
The technical problems to be solved in the utility model is to provide that a kind of processing technology is simple, the electric cleaner that intensity is good, cost of production is low of self cast steel ironware coupling.
The utility model is achieved through the following technical solutions:
The utility model electric cleaner is made up of motor rotation axis, coupling and electroceramics rotating shaft with cast steel ironware coupling, it is characterized in that: described coupling is provided with keyway, interior round tube hole and U-groove bevel.
As preferably, described coupling adopts Cast Steel or ironcasting.
As preferably, suitable employing cast-aluminum die when described coupling adopts ironcasting, makes the dimensional accuracy of ironcasting and surface finishment higher.
As preferably, after described coupling cast form in round tube hole need be through machined into, the diameter of interior round tube hole and the external diameter of motor rotation axis are suitable.
As preferably, after described coupling cast form, keyway need be processed through slotting machine, the width of the key on its width and height and motor rotation axis and highly suitable.
As preferably, its external diameter after described coupling cast form, two end faces and U-groove bevel are not done gold machining, and the interface internal diameter of its external diameter and electroceramics rotating shaft is suitable, and the cotter diameter of the width of U-groove bevel and electroceramics rotating shaft is suitable, and gap is all larger.
As preferably, the keyway of described coupling and U-groove bevel be orthogonal is the 90 degree settings of being separated by.
When on-the-spot installation, coupling is enclosed within on the motor rotation axis with key, and the interface of electroceramics rotating shaft is enclosed within on coupling, and the pin of electroceramics rotating shaft is aimed at U-groove bevel.
The utility model compared with prior art, has following obvious advantage and good effect:
1. coupling adopts cast steel or ironcasting, and gold machining amount is few, saves cost of material.
2. processing technology is simplified, and only needs internal round tube hole and keyway to carry out simple gold machining, has reduced man-hour and cost of production.
3. compared with gold machining part, Cast Steel or ironcasting are not easy to get rusty, and usability is better.

As preferably, described coupling 2 adopts Cast Steel or ironcasting.
As preferably, suitable employing cast-aluminum die when described coupling 2 adopts ironcasting, makes the dimensional accuracy of ironcasting and surface finishment higher.
As preferably, after described coupling 2 cast forms in round tube hole 22 need be through machined into, the external diameter of the diameter of interior round tube hole 22 and motor rotation axis 1 is suitable.
As preferably, after described coupling 2 cast forms, keyway 21 need be processed through slotting machine, the width of the key 11 on its width and height and motor rotation axis 1 and highly suitable.
As preferably, its external diameter after described coupling 2 cast forms, two end faces and U-groove bevel 23 are not done gold machining, interface 31 internal diameters of its external diameter and electroceramics rotating shaft 3 are suitable, and the diameter of the pin 32 of the width of U-groove bevel 23 and electroceramics rotating shaft 3 is suitable, and gap is all larger.
As preferably, the keyway 21 of described coupling 2 and U-groove bevel 23 be orthogonal is the 90 degree settings of being separated by.
When on-the-spot installation, coupling 2 is enclosed within on the motor rotation axis 1 with key 11, electroceramics rotating shaft 3 connect 31 muzzles on coupling 2, the pin 32 of electroceramics rotating shaft 3 is aimed at U-groove bevel 23.
